The difference between dry underfloor heating and wet underfloor heating

With the increasing popularity of underfloor heating, many homeowners who originally did not intend to install underfloor heating have begun to think about it: my house is not high enough, and I have heard that there is a kind of underfloor heating called dry underfloor heating, so is it possible to install it in my house?

Today, Youyou will analyze the advantages and disadvantages of dry floor heating and wet floor heating!

Wet underfloor heating introduction:

Wet underfloor heating is currently the most mature installation process, cost-effective, 90% of homeowners will choose it. The backfill layer of underfloor heating mainly serves the function of heat storage and heat dissipation, and the underfloor heating pipes buried in the ground provide heat to the room by heating the backfill layer, so as to achieve the effect of even and continuous heat dissipation.

Wet floor heating, as the name suggests, above a layer of wet cement mortar mix to do the heat storage layer. First lay a layer of insulation board on the ground, and then in the insulation board on the reflective aluminum film, and then in the aluminum film on the floor heating coils, the use of nails will be fixed in the pipeline on the insulation board, and then finally in the top of the anti-fracture silicone crystal mesh.

Because the underfloor heating coil is fixed on top of the insulation board, the insulation effect is better.

Advantages and disadvantages of wet floor heating:

Wet floor heating dissipates heat evenly and is thermally inert, even if the outdoor temperature suddenly becomes cold, or the water supply temperature changes, the indoor temperature change is not obvious, and the comfort level is very high.

Because of the backfill layer of wet floor heating, the floor height increases by about 7-8 centimeters after the floor decoration material is done, so if the room is shorter, the room will be very depressing. Maintenance and construction is more cumbersome.

Introduction of dry underfloor heating:

Dry underfloor heating can also be called thin underfloor heating, which is thinner because it has no backfill layer. Generally, thin underfloor heating is mostly used in rooms with shorter floor heights.

Advantages and disadvantages of dry underfloor heating:

Thin underfloor heating has the advantages of not occupying the height of the space, warming up faster, easy to maintain and so on.

There are advantages and disadvantages of thin floor heating, thin floor heating because there is no backfill layer (heat storage layer), so the thermal inertia is poor, if there is a change in the outdoor temperature or water supply temperature, the indoor temperature changes significantly.

Contrast

1, floor heating thickness: dry mounted in the thermal insulation module, directly on top of the floor heating floor, accounting for the layer height of about 4-5CM. Wet floor heating first in the cement surface after laying insulation board and then laying floor heating pipe, after pouring with soybean stone concrete leveling, plus the ground decorative layer, the height of the general 7-8 centimeters.

2, the degree of energy saving: dry floor heating and wet floor heating are more energy efficient than the heater, generally about 25% more energy efficient than the heater. If compared with the air conditioning with electricity, it is even greater to save money.

3, warming time: dry floor heating is hot and cold fast, the general warming time of 20-30 minutes, the corresponding cooling time is also 20-30 minutes on the cool. Wet floor heating hot slow cold slow, the general warming time takes 3-4 hours, but the advantage is that even if the bath time is long, the boiler priority supply of domestic hot water to go, not on the floor heating, wet floor heating will only cool down after 3-4 hours, a short period of time people indoors hardly feel the temperature fluctuations.

4, thermal insulation: wet floor heating is generally used more than 2cm of extruded plastic board, or even white crystal board, so the thermal insulation effect is very good. Dry floor heating is now generally modular, because of the extrusion board slotting process is difficult, so the majority of polystyrene board, its long-term thermal insulation is not as good as the extrusion board.

5, easy to install: dry floor heating installation, construction is extremely convenient, generally installed before laying the floor. Wet floor heating multi-layer composite, fixed coil, pouring the ground, the process is more complex than dry, generally installed after the completion of water and electricity.

6, comfort: wet floor heating heating comfort is better, stable temperature. As for the feel of the feet depends on what you install the ground material. Dry underfloor heating construction is not careful, if the later may walk sound.?

7, investment cost: dry floor heating and imported radiators heating is comparable, slightly higher than the general wet floor heating about 25%. Wet floor heating is generally comparable to ordinary radiator heating, plus the cost of backfill layer is equivalent to the cost of mid-range heating.
