I. What is underfloor heating

What is underfloor heating? p>Floor radiant heating, referred to as floor heating, is a technology that is both old and new. The use of floor heating in China can be traced back to the end of the Ming Dynasty, at that time it was the palace royal family can only have a way of heating, the existing Forbidden City in Beijing is a good representative. Later the powerful and big families and other people with spending power can also be used.

The first underfloor heating is in the brick floor under the good flue, winter through the flue smoke and reasonable configuration of the smoke window to achieve the brick warm and then transferred to the interior, so that the effect of indoor warmth. Later, the fire wall and kang were built in the northern countryside of China, and Korea and Japan learned from them, and the floor kang was built.

From ancient times to the present, human beings continue to inherit civilization, innovation and development progress. Now with the advent of the age of science and technology, the ground heating technology has developed from the original flue cooling kang type heating to modern materials as the heat medium of the ground radiation heating. The technology began to be applied in developed countries as early as the 1930s, and China has applied the technology to the Great Hall of the People, Overseas Chinese Hotel and other projects in the 1950s.

Second, the principle of floor heating

Floor radiation heating is the entire ground as a radiator, through the floor radiation layer of the thermal media, uniform heating of the entire ground, the use of the ground's own heat storage and the law of upward radiation of heat from the bottom to the top of the conduction, to achieve the purpose of heating.

Because of the indoor formation of the soles of the feet to the head of the gradually decreasing temperature gradient, thus giving a person warm feet cool comfort, which is in line with traditional Chinese medicine, "warm feet and top cool" fitness theory, is currently the most comfortable way of heating, but also a symbol of the quality of modern life.

Three, floor heating classification

The classification of floor heating is divided into two categories of water and electric floor heating from the heat medium, from the pavement structure is divided into wet floor heating and dry floor heating two kinds of floor heating, from the surface decoration material is divided into floor heating and floor tiles floor heating; from the functionality of the ordinary floor heating and far-infrared floor heating.

1, water underfloor heating

Water underfloor heating, i.e., low-temperature hot water floor radiant heating, is a heating method that uses hot water with a temperature of not more than 60 degrees Celsius as a heat medium, circulating in the heating pipe, heating the floor, and supplying heat to the indoor heating method through the ground in the form of radiant (primary) and convective (secondary) heat transfer. It is characterized by warmth, comfort (even heat dissipation without dryness), health and energy saving.

(1)Dry floor heating

Dry floor heating, compared to ordinary floor heating needs concrete and other materials backfill installation, it does not need to backfill, so it is named dry floor heating. It is also known as ultra-thin floor heating because it does not require backfill and reduces the occupied space. The reason for the lack of backfill is that the coils of the floor heating are stuck in the slots of the insulation board. Due to the ultra-thin nature of dry floor heating, it is mostly used in rooms with shorter floors, or rooms that are finely decorated.

Dry underfloor heating is in the form of a piece of module that has been connected, and when installing it, you only need to put together a piece of module in accordance with the designed drawing lines and the direction of the underfloor heating coils, and then you can quickly complete the construction of underfloor heating and decorate the floor.

The structure of dry underfloor heating module is thermal conductive layer, underfloor heating coil and heat insulation layer. Thermal conductivity layer is located above the thermal insulation layer, the thermal conductivity layer and the thermal insulation layer is fixed, between the two layers of the corresponding floor heating coil slot, floor heating coil slot for the inverted Omega-shaped pipe groove. Eliminate the need for pipe clips, and do not need to use glue to fix the film, not only does not take up the floor height but also to protect the floor elasticity and good comfort.

(2) wet floor heating

Wet floor heating is currently the most mature installation process in the water floor heating, but also more traditional floor heating. The price is relatively cheap, is the dominant process in the domestic floor heating market, the market share of about 90%.

The so-called wet type, that is to say, the floor heating pipes encased in concrete, and then lay the ground, tiles and other floor materials on top of the concrete layer. This layer of concrete not only plays a role in protecting and fixing the plumbing pipes, but is also the main channel for transferring heat. The concrete layer can make the heat evenly distributed, reducing the occurrence of localized overheating or overcooling.

The laying of wet underfloor heating is the largest project compared to other underfloor heating, but the cost is relatively low. First, the insulation pipe is lined up and fixed on the concrete surface, and then the sand and gravel concrete layer is poured, and only after it dries can the floor decoration work be carried out. As you can see, wet floor heating is a multi-layer composite structure with many and complex processes, and the installation work is usually carried out in the pre-decoration period. The use of cement concrete, the foot will feel more hard, the ground unit square meter load bearing weight than dry high, building load bearing is also heavier than the heater way to about eight times.

2, electric floor heating

Electric floor heating is the outer surface of the permissible operating temperature limit of 65 ℃ heating cable buried in the floor, heating cable as a heat source to heat the floor to thermostat control the room temperature or floor temperature, to achieve the heating method of radiant floor heating. Mainly have the advantages of comfort, energy saving, environmental protection, flexibility, no maintenance and so on. Generally divided into two kinds of heating cable heating and electric heating film floor heating.

(1) heating cable heating

Heating cable floor heating is a low-temperature heating cable as a heat source, heating the floor, through the ground to radiation and convection heat transfer to the indoor heating mode of heating. It is characterized by zero emission and no pollution, high heating rate, strong controllability, not affected by temperature, space saving, simple installation and low cost.

Heating cable floor heating is divided into single-core cable and double-core cable. From the point of view of electromagnetic radiation, double-core cable than single-core cable electromagnetic radiation is smaller, more suitable for home floor heating, while the single-core electromagnetic radiation is higher than double-conducting, used for outdoor floor heating system more.

From the design and installation, single-core to be more difficult, due to the single-core cable ends to be connected to the thermostat, you need to make the end of the cable back to the reasonable ground, so you need to design in the design of the design, construction, grasp the scale. Compared to single-core, double-core is better construction, where the end of the cutoff can be.

Heating cable heating system, not subject to environmental conditions, can be used for room heating, pipeline frost insulation, outdoor snow melting and ice melting, and so on any heating needs. The heating cable's radiant floor heating method uses the entire floor as a radiator, and the indoor temperature is evenly distributed, so you will have a warm and comfortable feeling at any location in the room.

(2)Electric film floor heating

Electric film floor heating system is composed of thermostat electric floor heating thermostat, connecting wires, connecting cards, insulation accessories, thermal insulation materials, electric heating film and finishing materials.

The electric heating film is the heating element of the floor heating system, in the electric heating film on both sides of the electricity, the positive and negative poles produce a voltage difference, the formation of electromagnetic fields, carbon molecular crystals in the alternating electromagnetic field to do Brownian motion, friction, collision and heat and far-infrared light waves emitted, and then by the floor uniformly to the indoor radiation of heat, and at the same time in the specific gravity difference between the hot and cold air under the action of the air's natural convection phenomenon, so as to achieve step heating. Thus, the heating effect is achieved in a step-by-step manner.

The electric film floor heating system can adjust the room temperature within the set temperature range through the AC thermostat set up in each room, so that people can save water and electricity as flexible and convenient heating. Because of the elimination of heaters and pipelines, the electric heating film heating system does not take up indoor space. It does not produce smoke and dust, no noise and no floating dust caused by indoor air convection, which is in line with the requirements of urban planning and suitable for the requirements of green environmental protection in modern society. It can be adapted to the needs of a variety of users, and can be metered by household, unit or floor, with the user controlling the electricity consumption freely.

Part2-What are the advantages and disadvantages of floor heating

One of the advantages of floor heating

1, healthy and comfortable

Because floor heating heating makes the indoor surface temperature uniform, giving a person with warm feet and cool head a comfortable feeling to improve blood circulation, and promote metabolism. And it is not easy to cause dirty air convection, so that the indoor air is clean.

2, energy efficient

Floor heating makes the heat concentrated in the height of the human body to benefit from, and heat loss in the transmission process is small. And low-temperature radiant floor heating can also be implemented in the stratification, household, room control, the user can be individually regulated according to the situation, effectively saving energy.

3, beautify the room

Indoor can not install the heater and its pipeline, you can free up more space to facilitate the decoration and home furnishing, and reduces the health of dead ends.

4, good thermal stability

Because the ground layer and the concrete layer of heat storage capacity, so the thermal stability of floor heating, and in the intermittent heating conditions, the indoor temperature changes slowly.

5, long service life

Floor heating PERT tubing buried in the ground, good stability, non-corrosive, unmanned destruction, long service life, but also saves maintenance and replacement costs.

Two, the shortcomings of floor heating

1, on the floor height of 80mm occupation, because the floor heating insulation board has 30mm, soybean stone concrete filler layer of 50mm, the total **** 80mm thick, so the indoor floor height has a certain impact.

2, floor heating is poorly maintainable, because floor heating is a hidden project, it is not easy to repair, so the renovation should choose pressure, temperature, corrosion resistance and good thermal stability of high-tech environmental protection tubing. And it is not easy to second renovation, because the floor heating hot pipes are laid in the ground, the second renovation to remodel the ground, it is easy to damage the underground piping. Also pay attention to the use of the temperature can not be set too high, otherwise it will reduce the service life of the delivery pipeline.

3, small space, such as bathroom use is limited, due to the floor heating heat pipes are more complex, laying floor heating coil before and after the waterproofing, small space laying range is small, so the room temperature is likely to reach the heating standard.

4, floor heating system in the operation of 2-4 years, the floor heating pipeline is prone to scale, which requires professional equipment for cleaning, otherwise it will directly affect the heating effect.

Part3-Electric floor heating and water floor heating which is good

Whenever the winter season, is also the peak season of the heating equipment. However, consumers will coincidentally have a question when choosing heating equipment. Electric floor heating and water floor heating which is good? Below I give you a comparative analysis of electric floor heating and water floor heating, to see which is better.

Electric underfloor heating and water underfloor heating which is good electric underfloor heating and water underfloor heating comparative analysis

A, electric underfloor heating and water underfloor heating effect comparison

Water underfloor heating and electric underfloor heating are installed under the floor, the bottom to the top of the uniform heat dissipation, indoor air convection weakened, less moisture loss, to avoid the production of skin dryness, fire, and other physical discomfort. The difference is that the electric floor heating there is a leakage and burn safety hazards, the protection of the insulation layer and the safety of the installation requirements are very high, and the use of electromagnetic fields will be generated, the human body caused by magnetic radiation damage. And water underfloor heating pipe is just water flow, there will be no major safety hazards.

Two, electric floor heating and water heating energy consumption comparison

The working principle of electric floor heating is the outer surface of the permissible upper limit of the working temperature of 65 ℃ electric heating film, heating cable buried in the floor, electric heating film, heating cable as a heat source to heat the floor to the thermostat control the room temperature or the floor temperature, to achieve the ground radiation heating. Electric floor heating using heating cable is a better effect of energy saving at the end, while electricity is renewable energy.

Water floor heating mostly natural gas as the main fuel, water as a fluid running in the pipeline to heat the ground heating system. Water underfloor heating and traditional convection heating compared to the energy saving of about 20%, such as the use of zoned temperature control devices, energy saving can reach 40%. Water underfloor heating in the transmission process of heat loss is small and the heat is concentrated in the height of the human body to benefit from, even if the indoor set temperature is lower than the convection heating method 2 ~ 5 ℃, can make people have the same warm feeling. And water heating heating boiler can provide domestic hot water, do not have to spend money to buy a water heater, eliminating the cost of purchasing a water heater.

Three, electric floor heating and water floor heating installation comparison

Water floor heating system is usually composed of heat source equipment, heating mains, manifolds and collectors, temperature control systems, ground structural layer. Large houses are also equipped with heating circulating water pump (pressurization), thermostatic mixing valve (energy-saving and good comfort) and so on.

The composition of the electric floor heating system mainly consists of the ground layer, adiabatic insulation layer, structural layer, heating cable, power supply, thermostat, floor heating controller and so on. Due to the different composition of the system, the installation of electric underfloor heating is faster than water underfloor heating, and usually the installation of electric underfloor heating in a family house of 200_ saves one day's work period than the installation of water underfloor heating. And the water floor heating system is complex, the construction technology requirements are higher, need skilled installation team to protect the quality of the project, to eliminate security risks.

Four, electric floor heating and water floor heating cost comparison

Electric floor heating is composed of underground heating cable and temperature control system on the ground, the main unit heating area to calculate the cost of installation, the larger the area, the larger the investment per unit area; water floor heating is composed of a number of components such as heating boiler, geothermal piping, manifold, control system, valves, etc., the installation cost is not fixed. The heating boiler of water underfloor heating can supply domestic hot water at the same time, the larger the area of the house, the smaller the investment per unit area. Usually we recommend that small areas of households to install electric floor heating is more cost-effective, while large households and villa users to install water floor heating is more economical and energy-saving.

Part4-Underfloor heating or heating?

As the saying goes, an autumn rain is a cold. Although it is not really "escape" from the summer, but the rainy day temperature gradually with the fall on track. The north can choose heating, the south can be warmed with floor heating. Compared with the two, floor heating or heating is good?

A, what is heating

Heating, narrowly defined as a centralized heating facilities. It consists of pipes (i.e., heating pipes) that carry steam, or hot water, produced by a boiler to radiators (i.e., heaters) in the room or car, dissipating heat to increase the room temperature, and then flowing back to the boiler to reheat and recirculate. The water used for heating must be clean water for human health and the environment.

Cities north of the Qinling-Huai River in China basically have city-wide scale heating pipeline networks operated by the government or government-appointed companies to provide centralized heating services in the winter, with the level of service, charges, and start and end dates of heating varying from place to place. Cities south of the Qinling-Huaihe River generally do not have city-wide scale heating networks, but smaller scale (e.g., neighborhoods, campuses, factories) heating networks exist.

Two, floor heating or heating is good?

1, floor heating or heating good installation effect

Heating heating is installed in the outside window under the heater (such as restrictions on the installation of the inner wall), generally using the open installation, the pipeline dark laying under the ground. At present, the heater is generally used steel plate, aluminum alloy and copper-aluminum composite heater, the pipeline using copper and PEX tubes and so on. This way of installation occupies the horizontal space of the room, affecting the placement of furniture, the installation of the heater is subject to whether the wall can be fixed bracket constraints.

Floor heating is a hidden system, floor heating pipe buried in the ground, does not affect the wall decoration and furniture placement, not subject to whether the wall can be fixed bracket constraints, the advantage of this is particularly obvious in the surroundings are floor to ceiling glass and other spaces. Because the floor heating is buried in the ground heating system, will increase the net height of the room, in general, the wet floor heating to increase the height of 8cm, dry floor heating to increase 4cm.

2, the floor heating is good or good heating effect

Heating heating is convection-based heating. The heater first heats the air around it, so that the air in the room to form convection to achieve the purpose of heating. In this way, the temperature around the heater is high, with the increase in distance from the heater, the temperature decreases, the temperature difference between the same level is large, especially in large rooms. Because this heating is convection, hot air convection from top to bottom, the room temperature is hot on the bottom of the cool, giving the feeling of a hot head and feet cool, relatively poor sense of comfort.

Floor heating is based on radiant heating, heat from the bottom to the top of the uniform radiation heat, the room temperature at the same level of uniformity, temperature difference is small, giving the feeling of hot foot cool, in line with Chinese medicine, "warm feet and top cool" health care theory, both energy saving and comfortable.

3, floor heating or heating good thermal efficiency

Heating out of the higher temperature, the temperature of the room in a short period of time began to rise, the thermal efficiency is very high, nowadays, young people have a high efficiency heating needs, hope to be able to heating in a short period of time users choose the heater heating will be better.

Floor heating in the water floor heating water specific heat is larger, so the warming is slower, especially the initial opening, the temperature of the whole house needs to rise for a long time, so the water floor heating is generally open 24 hours. Electric underfloor heating warms up faster and can raise the indoor temperature in a short time, but you can't adjust the temperature too high all at once, so it's easy to damage the cable components.

4, floor heating or heating good energy efficiency

Heating belongs to the air convection cooling, the required water supply temperature is high, and most of the heating is not added temperature control device, even with the addition of temperature control system, the energy saving effect is still not obvious, while the floor heating than heating energy saving 30%.

Floor heating is a low-temperature radiation, the required temperature is lower, and floor heating with temperature control, temperature control function, for centralized heating may not have much advantage, but for the independent heating system or centralized heating system of sub-metering, energy saving effect is more obvious.

Part5-underfloor heating with what flooring is good

Select floor heating floor requirements

The floor heating floor of the requirements of the wood is particularly strict, the first can is the requirement of high-temperature resistance, which is the wood is specially treated, even if it is immersed in 100 degrees of hot water will not be cracked, degumming, deformation and warping, due to underfloor heating flooring planks to be in a long-term in the high temperature environment, so the environmental protection of the flooring is very important for the environment, the floor heating is a good choice. High-temperature environment, so the requirements for environmental protection is also very demanding, the required formaldehyde emissions must meet international standards, or in the high temperature of the baking than ordinary plates are more likely to release toxic substances.

Choice of floor heating floor requirements, first of all, to punch the wood to start, to see if its moisture content is not too high, no drying process, otherwise long time high temperature will evaporate moisture, wood will shrink to produce chaffing. Then it is important to look at the choice of experienced, technologically mature manufacturers, this type of manufacturers tend to do a long history of wood flooring, in all areas are comfortable, to make the floor heating wood flooring environmental protection, durability are more reliable.

Installed floor heating floor how to choose

And in the choice of the type of electric heating, it is best to be able to choose multi-layer composite flooring, this composite flooring after technological innovation, both laminate flooring wear-resistant and solid wood composite flooring resistance to deformation, practiced in the three major harsh environments (public **** occasions, geothermal, humidity) are excellent performance. The requirements in terms of use and maintenance are also different.

The choice of floor heating flooring must pay attention to a few hard indicators, one is the absorption of the thickness of the expansion rate is best to be in the 2.5% of the next, the general water thickness of the expansion rate can not exceed 4.5%. Also note that there should be wear-resistant layer and very high wear-resistant rpm, such as in 9000 rpm or so, otherwise sandpaper sanding, the surface pattern will be polished and whitened. Environmental protection is also very important, every hundred grams of product formaldehyde emissions can not exceed 40 milligrams. And the water content must also be between 3% and 10%.

Choice of floor heating flooring is also able to choose according to the color, such as the living room requires a high degree of brightness, we should start with a bright warm yellow or white-yellow, to create a bright, open, elegant environment, while the bedroom can choose a warm color floor heating floor heating, to give you the mood to relax, feel serene and soothing. If it is a children's room, you can choose bright light-colored flooring, while places such as the study are more suitable for dark decorative flooring.

Part6-Bathroom underfloor heating to install underfloor heating is used more and more frequently in people's lives. Many homeowners choose to use underfloor heating to ward off the cold and create a warm home for their families when they are decorating. However, when the living room, dining room and bedroom become warm, the bathroom is cold. I am a person who does not like to take a shower in winter because it is really cold. I thought it would be nice to install underfloor heating in the bathroom. But is underfloor heating in the bathroom really good?

Bathroom underfloor heating is good - to solve the damp, high comfort

In winter, in the bathroom bath will encounter the bathroom temperature is not enough and the problem of wet ground after the bath, the emergence of these two problems will affect the family in the winter use of the bathroom comfort. If you lay floor heating in the bathroom, you will be able to solve these two problems at once.

Even cooling from the ground, on the one hand, to solve the traditional family use bath can only dry to the head of the limitations of the bathroom bath to increase the comfort of the soles of the feet, and on the other hand can be after bathing the wet ground drying, to solve the bathroom hygiene and humidity problems. Therefore, at present, many high-end buildings and high-quality families will be in the bathroom floor heating.

Bathroom underfloor heating is good - beautiful and generous, cost-effective

In the various rooms of the home, the bathroom area is relatively small, if the floor heating in the bathroom, will not take up additional area in the bathroom, will not appear such as bathroom installation of radiators, bathtubs, and other heating equipment abruptly, so that the entire bathroom is more beautiful, generous, and save a lot of use area for the bathroom. Save a lot of area.

In addition, due to the long service life of the floor heating, almost the same life with the building, and if the installation specification, the later almost no need for maintenance, can be said to be a one-time investment in a lifelong income.

Bathroom underfloor heating is good - bathroom paving underfloor heating precautions

Bathroom because the area is relatively small, and buried underground pipeline far more than other rooms, so the process of installing underfloor heating in the bathroom is more complex compared to other rooms. It is recommended that families who need to install underfloor heating in the bathroom should pay attention to the following aspects:

First, the bathroom is the place where the family uses the most water, so the most important thing to pay attention to when laying underfloor heating in the bathroom is to pay attention to the waterproofing, in general, the professional underfloor heating installation company in the bathroom when laying the underfloor heating, they will do waterproofing twice, once before the underfloor heating pipe is paved, and once after all the installation, in order to ensure that the temperature of the underfloor heating.

Secondly, there will be more things laid on the bathroom floor, such as toilets, bathtubs, basins and all kinds of sanitary appliances, which makes it more difficult to distribute the temperature from the bottom to the whole room, which affects the amount of heat supplied by the underfloor heating of the bathroom, so when laying the underfloor heating in the bathroom, it is usually designed in accordance with the temperature of 20 ℃ - 24 ℃.

Third, bathroom underfloor heating especially when used in winter, because of the need for higher heat load and heat supply, in the selection of underfloor heating it is best to choose high-power products, you can avoid the need for high heat when the heating is not enough to affect the bathroom temperature is not enough.

Bathroom floor heating is good? Through the above introduction, bathroom floor heating can be said to have many benefits, clean and warm bathroom can make the whole family more cozy and comfortable. Families in the careful consideration of the bathroom paving underfloor heating precautions, the application of underfloor heating in the bathroom so that the bathroom can have a truly the most hygienic room in the home, is a whole new experience of the bathroom habits of the whole family.

Part7-Floor heating installation steps

Floor heating is not only winter heating equipment, but also relates to the layout of the interior decoration, good floor heating installation can undoubtedly be the icing on the cake for home decoration, to achieve the perfect combination of comfort and energy saving. So in the construction of home heating decoration, how to install floor heating? What is the process of floor heating installation? Below we will learn about the steps of floor heating installation, I hope it can help you.

Floor heating installation steps water floor heating installation steps

One, pre-installation inspection

Prior to construction, the installation company should first test the ground leveling layer, and hand over the site with the owner to determine the location of the thermostat, manifold, wall-hung boiler and wall-hung boiler flue holes, etc.. At the same time set up the size and size of the need to reserve, to facilitate the installation company to go pipe wiring.

Two, the installation of water heating manifold

Water manifold according to the pre-determined position against the body installation, installation to do straight, firm. Wall-hung boiler and wall-hung boiler main positioning and determine the location of the flue.

Three, laying insulation board

Cut insulation board according to the actual size, laying, laying to leave a gap for the pipeline. Heating materials include heat source (wall-hung furnace), cooling end (radiator), pipe fittings pipe and temperature control system. In the process of laying insulation board should ensure that the site is clean and tidy, insulation board is mainly to play a role in insulation, to prevent the use of floor heating temperature transfer downward.

Four, laying reflective film and steel wire mesh

Reflective film shall be close to the insulation board, laying reflective film is to prevent the floor heating pipe heat downward radiation (i.e., radiation conduction), steel wire mesh can be fixed to the pipe, increase the load-bearing pipe, effectively preventing the floor from cracking.

Five, laying pipes

The floor heating pipe laying on the construction technology requirements are very high, in order to ensure that the late use of floor heating when the heat dissipation is uniform, floor heating pipe laying also requires floor heating pipe must be evenly distributed on the ground, the distance between the tube and pipe 200mm, after laying a good with plastic nails will be fixed to the floor heating pipe on the insulation board. Be careful not to pollute the pipes during installation.

Sixth, connect the floor heating pipe and manifold

Connect the floor heating pipe and manifold, check whether there is any damage to the pipeline, and the system for water pressure test. After checking the laying of the pipeline without damage and pipe spacing in line with the design requirements, the first system for flushing, and then carry out water pressure test.

Seven, laying concrete layer

Concrete layer of the entire floor heating system plays a protective role, can be fixed water pipe, to protect the water pipe to avoid deformation due to thermal expansion and contraction of extrusion, at the same time, can make the heat distribution more uniform, the user feels more comfortable.

Eight, laying floor materials

Laminates and tiles are more suitable for floor heating floor materials, ceramic tile thermal conductivity, resistance to deformation is strong, is the ideal choice for floor heating. In recent years, there are a lot of processed solid wood flooring can also be used in the floor heating, this time you need to understand clearly and then purchase and install.

Nine, the installation of wall-hung boilers

Installation of wall-hung boilers on the entire water supply loop water temperature and hydraulic balance debugging.

Floor heating installation steps of electric floor heating

Electric floor heating is becoming more and more common, the following look at the general steps of its construction:

1, laying insulation

Polystyrene insulation board should be laid on a flat and clean structural surface. Laying should be cut neatly, the gap shall not be greater than 10mm, between the insulation board should be smooth adhesive tape.

2, laying wire mesh

Wire mesh will be laid on the polyester vacuum aluminized film, the joints should be tied at the binding tape tied firmly between the wire mesh should be lapped and tied fixed. If the cable is fixed with a nail or fixed with a fixed band to fix the heating cable, the wire mesh should be laid in the pebble concrete filler layer.

3, laying heating cable

Heating cable must be laid according to the design drawings required spacing on the wire mesh, with lashing will be fixed in the wire mesh heating cable, or with a fixed belt or with a nail will be fixed in the heating cable insulation layer.

4, heat with air measurement

Heating cable laying is completed, according to the drawings to check whether it meets the design requirements and use a multimeter and shaking table (500MΩ) to detect the nominal resistance of each cable, insulation resistance, to ensure that the heating cable is not disconnected, short-circuit phenomenon. Before pouring pebble concrete must be energized to detect the heating effect of the heating cable.

5, pouring pebble concrete filler layer

pebble concrete into the laying area must be set up to transport pads, trolleys and other tools can not be directly pressed heating cables; concrete pouring should be gently tamped with wooden tools, do not vigorously ramming; filler layer is not allowed to be stepped on within 48 hours of the completion of the filling layer, filler layer of the ground after the completion of the construction of the ground is forbidden to chiseling, heavy loads.

6, the cable again test

Fill layer construction is completed, and then use a multimeter and shaking table (500MΩ) to detect each cable to check the heating cable in the filler layer construction process is not damaged.

7, thermostat installation

Should be installed before the delivery of the project, the installation of the thermostat installation instruction manual shall prevail, the installation should be energized after the test, after the test with tape wrapped to avoid damage.

Part8-Floor heating cleaning prices and precautions

Floor heating is one of our most common heating system, when we use for a long time, it is not inevitable to be cleaned, usually we will ask the professionals to clean, then how much is a floor heating cleaning?

Floor heating cleaning how much money of the cleaning method

Chemical immersion, projectile cleaning, pulse wave physical cleaning. Pulse cleaning method used in the floor heating the most, can be the floor heating pipe as well as the splitter of the scale and impurities in a one-time clean.

Floor heating cleaning how much money by square

(geothermal heating area) is now generally 2-3 yuan a flat is more reasonable.

How much does floor heating cleaning cost per circuit

A circuit is basically 50 yuan, and now most of the cleaning units to clean the cost of cleaning is basically provided as a reference only. For example, in Beijing, for example, one hundred and eighty square meters of the house cleaning a rough cost of five hundred to seven hundred or so, depending on the floor heating cleaning company charging mode, different cleaning organizations, different cleaning methods, the cleaning costs charged are not quite the same.

Floor heating cleaning how much money of floor heating cleaning precautions

Cleaning time: floor heating cleaning time in the heating before, during or after heating can be. Cleaning before heating, you can clean all the biological slime and other impurities in the pipeline, so that the heating effect to achieve the best state; cleaning in the heating, you can clearly feel the change in temperature rise; and cleaning after heating is relatively better, you can remove the impurities to prevent bacteria in the floor heating pipes to reproduce.

Cleaning cycle: According to relevant statistics, in the heating process, the floor heating pipe lining every increase of 1mm of dirt, will make the ambient temperature down 6 ℃, so it is necessary to clean in time, usually in 3-5 years cleaning.
