Advantages and disadvantages of natural gas heating

Advantages of gas wall-hung boiler heating

1, energy saving and environmental protection, because it doesn't waste a lot of heat on the pipeline like central heating. Relatively speaking, gas-fired wall-hung boiler heating improves heating efficiency.

2, save money, gas-fired wall-hung boiler heating costs less than central heating (burning gas). Take "Anrui" 24KW wall-hung boiler with rated gas consumption of 2.4m3/h as an example. If the room is about 100 square meter, the room temperature is constant at 20℃, the wall-hung boiler runs intermittently for 5 hours all day, and the daily gas consumption is 12 m3. As can be seen from the above, a house with an area of about 100 square meter is heated by a gas-fired wall-hung boiler in one heating season, which saves 264 yuan compared with the central heating (gas). The use of gas-fired wall-hung boilers for heating is obviously more expensive than central heating (burning coal). If your home is heated by a wall-hung boiler, I suggest you install a thermostat, which can achieve a certain energy-saving effect. If there is no one at home or the temperature is lowered at night, the natural cost will be reduced accordingly.

3. Flexible heating, not limited by central heating time. The heating time can be set freely and turned on at any time. The starting time can be preset to make life more comfortable, and the temperature of each room can be adjusted at will within a certain range.

4, indoor dual-use, gas-fired wall-hung boiler can provide both heating and domestic hot water.

Disadvantages of gas wall-hung boiler heating

1. Wall-hung boiler heating allows you to enjoy energy conservation and environmental protection. If used improperly, there will be problems such as high failure rate and potential safety hazards.

2. In the first heating season of the new house, there is a lot of water vapor in the wall, or because the occupancy rate of the community is low, when heating by itself, the heat will be conducted to the uninhabited neighbors through the wall, floor and ceiling, which will not only affect the heating effect, but also cause waste of resources.

3. The service life of ordinary wall-hung boilers is usually around 10 years, so they have to be replaced after 10 years, and this cost can only be borne by the owners themselves.

Usage of gas wall-hung boiler

1, water injection;

The newly installed gas wall-hung boiler is filled with water first. The water injection method is to open the exhaust valve first, and then open the water supplement valve of the wall-hung boiler to replenish water. When the makeup water pressure reaches 1.0— 1.5bar, be sure to close the makeup water valve, otherwise the overpressure relief valve of the system will always leak water, which may soak indoor items. Then observe whether there is water flowing out of the exhaust hole of the exhaust valve. If there is water flowing out, it means that the system water has been filled up, and the exhaust valve can be closed.

2. Power on;

Turn on the power switches of all gas-fired wall-hung boilers and let them start working. It should be noted that the wall-hung boiler uses a leakage protection plug, and press the on key in the middle to connect the power supply.

3. Operation;

The operation here refers to the trial operation. Let the gas wall-hung boiler run for 5 minutes, and then turn on the ignition after the air in the system is exhausted and the water pressure in the system is stable.

4. Temperature setting;

There are two kinds of gas wall-hung boilers, one is a single function, which can only provide heating, and the other is a wall-hung boiler with heating and bathing. If it is dual-function, the temperature should be set for both. If it is radiator heating, the temperature should be set at 80 degrees. If it is floor heating, the temperature should be set at 60 degrees. However, the set temperature of domestic hot water should not be higher than 50 degrees. As the water temperature of Anrui gas wall-hung boiler is low when it is used for the first time, please don't set the temperature too high. If the water temperature is too high, it is easy for the wall-hung boiler to run for a long time without reaching the set temperature.

5. Adjust the water temperature;

Here is to adjust the temperature of the bath water. In winter, the temperature can be set below 42 degrees, which will burn people if it is too high. In summer, the water temperature can drop by one or two degrees. The correct operation steps for users are to open the gas valve → start the machine → then adjust the winter and summer modes, and press the up and down keys to adjust the water temperature for heating or bathing. If there is no ignition, the water pump is usually stuck. Turn the water pump impeller several times with a flat screwdriver. If the problem cannot be solved, please contact the after-sales service personnel.
