Home gas boiler why the circulating pump is always non-stop turn?
Circulating pump during the heating work, as well as the user when using hot water, is to be running. In the following three cases, the circulating pump of the boiler will rotate. 1, it needs to heat the heating water to the radiator, to warm the end of the heat, the cooling of the low-temperature water pump back to the combustion chamber of the heat exchanger. 2, for the plate for the model of the boiler, the use of hot water when the circulating pump is also working, the need for hot water to the plate heat exchanger, used to heat tap water. 3, the boiler in order to achieve the anti-freeze, anti-jamming design needs, the need to lower the temperature below 5 ℃, or every 24 hours automatically run the circulating pump (and fans, gas valves and other components) about 5 minutes, or heating Water temperature rose to about 30 ℃. If the boiler downtime, the circulating pump is still running, then the failure, the need for after-sales maintenance.
Gas boiler water pump will automatically start and stop according to the water temperature, under normal circumstances during the water pump is kept non-stop. Because the pump operation can make the system temperature uniformity, the temperature inside the furnace can reflect the system temperature. But not all brands of fireplaces are so. So the pump motor is not working properly.
