The wall-hung boiler is turned off during the day and turned on at night, saving gas? Or is it to save fuel and open 24 hours a day?

Answer: the wall-hung boiler needs to save gas, and it is not turned on during the day and night, nor is it turned on 24 hours. My experience mainly includes the following ways to save money:

1, set the water supply temperature reasonably.

The operation and start-stop of the wall-hung boiler is mainly based on the temperature difference between the water supply temperature and the backwater temperature, which is usually 10 degrees. For example, when the water supply temperature is set to 60 degrees and the backwater temperature reaches 50 degrees, the wall-hung boiler will stop. When the backwater temperature is lower than 49 degrees, the wall-hung boiler works. Therefore, users should set the temperature normally and reasonably, such as floor heating. Setting the water supply temperature of 50 degrees and the water supply temperature of 58 degrees will bring different energy saving.

However, users can't unilaterally reduce the water supply temperature in order to save, so the indoor temperature is very poor, even less than the heat lost by the house, which will bring the wall-hung boiler to run for a long time and increase energy consumption; Don't blindly pursue indoor high temperature, improve the water supply temperature.

2. Set the temperature of the indoor thermostat reasonably.

The wall-hung boiler is controlled by a thermostat, and the temperature value of the thermostat should be set correctly. At this time, the start and stop of the wall-hung boiler is determined by the monitoring of the room temperature by the indoor thermostat. When the indoor temperature is 0.5-2 degrees higher than the preset value, it will stop; When the indoor temperature is lower than the preset value of 0.5-2 degrees, the wall-hung boiler will start to run.

Therefore, when the preset indoor temperature is 18-20 degrees, it is the most energy-saving and comfortable; On the other hand, in a system with multiple thermostats at home, we must pay attention to the unification of the preset temperature of each thermostat, which will bring lower energy consumption. However, due to the error of the temperature controller, the start and stop of the wall-hung boiler will increase, and the energy consumption will naturally be greater.

3. Correct design of control system.

As mentioned earlier, whether floor heating or radiator is used, if backwater is used to control the temperature, it is easy to have deviation, and the temperature deviation value is very large, so the probability of restarting the wall-hung boiler is very high, so it is not gas-saving. Just like a light bulb, voice control definitely consumes more power.

In addition, due to the use of indoor thermostats, such as a three-bedroom with four thermostats, the wall-hung boiler may never stop because of the temperature difference set or perceived by these four thermostats, which will bring high energy consumption.

Therefore, the general flat-type or single-component water collector (8 circuits/group) uses only one thermostat as far as possible, so the wall-hung boiler is the most gas-saving.

abstract

The gas saving method of wall-hung boiler is not to let it run day and night, let alone 24 hours, but to let it automatically control the temperature, so that the indoor temperature is constant at 18-20 degrees.
