We sometimes see that the external thermostat of the wall mounted furnace can save energy by 30%. Is that true? Is it a gimmick or can it really save energy and gas?
The temperature controller is divided into wired and wireless, but the principle is the same: after the temperature controller is installed, a switch is connected in series to monitor the indoor temperature in real time. If the indoor temperature reaches the ideal temperature, the switch is disconnected to stop the combustion of the wall mounted furnace, which will not make the room hotter and hotter, so as to achieve the purpose of saving gas. This is also the reason why adding a temperature controller to the wall mounted furnace can save energy and gas in essence.
However, the actual situation is that in case of poor insulation of the house and poor efficiency of the heating system, it is difficult to reach the set temperature when the wall mounted boiler is always open, or when the set temperature is reached, the indoor temperature will soon drop again. At this time, the thermostat has been in the relay closed state, and the wall mounted boiler still continues to work according to the original mode. This thermostat is equivalent to a decoration, not to mention energy saving.
Therefore, there are two key prerequisites for installing the thermostat to save gas: the thermal insulation performance of the house and the heating system are better.
In these two cases, the installation of temperature controller can really save gas.
