In winter, many families will choose to use gas wall-hung boilers for heating, but many people may not understand what this principle is when they buy it
The principle of gas wall-hung boiler heating is mainly to generate heat energy by burning gas, and then transfer the heat energy to the heating water to increase the temperature of the heating water. The heated heating water is pumped to the radiators, floor heating and other terminal equipment to dissipate the heat into the room for heating.
Specifically, the combustion chamber in the gas wall-hung boiler transmits the high-temperature flue gas and combustion products generated by gas combustion to the heating water through a heat exchanger, so that the heating water is heated. The heated heating water is sent to the radiator, floor heating and other terminal equipment by circulating pumps, and the heat is dissipated into the room through heat dissipation to raise the indoor temperature.
At the same time, the gas wall-hung boiler also has an automatic adjustment function, which can automatically adjust the temperature and flow of the heating water according to the change of indoor temperature to keep the indoor temperature stable.
In a word, the principle of gas wall-hung boiler heating is to generate heat energy by burning gas, and then transfer the heat energy to the heating water, so that the indoor temperature rises and remains stable.
Advantages and disadvantages of gas wall-hung boiler heating
First, the advantages of wall-hung furnace heating.
1. Free heating time.
If you use a wall-hung stove for heating, you can set the time freely, which means that you can set it according to your own needs. At the same time, the temperature of each room can also be adjusted according to different needs. In addition, the wall-hung boiler can also provide us with domestic hot water during the heating period, without the need to use a water heater, which not only saves money, but also saves space.
2. Safe and economical.
The wall-hung boiler is a high-safety heating equipment, which is very in line with the principle of heat charging in all aspects, and the amount of gas consumed can be accurately calculated and the user can control it by himself. At the same time, this kind of equipment can also play a certain role in saving gas, it is mainly natural gas, liquefied petroleum gas and other energy sources, in addition to being installed in the kitchen, can also be installed in the balcony basement and other areas.
3. Comfortable and convenient.
It is very convenient to use a wall-hung stove for heating, and it is also very comfortable to use. It is the use of indoor pipelines to connect radiators to achieve the effect of heating and domestic hot water at the same time, that is, the role of double circuit. If you install a thermostat, you can also adjust the temperature of different spaces, and when there is no one at home, you can set the temperature at a low temperature to save energy consumption, and if you install a timer, you can also preset the use time, which is very convenient to use.
Second, the shortcomings of wall-hung boiler heating.
1. High maintenance costs in the later stage.
When the wall-hung boiler is used daily, it needs to be maintained regularly, and it will be more troublesome. For families who have no one at home for a long time in winter, it must be kept in a state of low temperature burning, otherwise the pipes are easy to freeze. At the same time, the cost of later maintenance is relatively high, because the furnace will become less and less efficient after a long time, and it needs to be replaced after the service life, and the cost needs to be borne by the user.
2. High heating costs.
Since the main gas source used in the wall-hung boiler is natural gas, if a small furnace is used, its combustion efficiency is relatively low, which increases the cost of heating. Especially for families with children and the elderly, the cost of heating is naturally high when they need heating all day.
3. High noise.
During the use of the wall-hung boiler, it will make loud noise, and there are some potential safety hazards, and it will pollute the local environment. Because the carbon dioxide and other substances emitted by natural gas when used will cause certain pollution to the surrounding environment, especially for high-rise residential buildings.
