For example it is common for gas water heater, then install the hot water circulation system, when the circulation of the hot water is not up to the temperature after the start will heat the circulatory system, then the gas water heater will follow up?
2, timing control: water in the peak period every day, turn on the return of the circulating pump.3, temperature time control: the above two methods combined with the backwater system.4, manual control: set up the water pump starting switch at the water point, start the circulating water pump with hot water for a few minutes, and then use the water.
Backwater control usually has:1, constant temperature control, a temperature sensor is arranged in the hot water pipe network at the end of the water pipe, when the temperature is lower than the set value, the circulating water pump start, cold water will return, water flow, water temperature reaches the set value when the pump stopped.
The hot water circulation system generally refers to the hot water return cycle, when the hot water is from the water point distance, hot water pipeline memory product has a lot of cold water, again, these must discharge the water pipe to use hot water. This leads to waste of water resources and inconvenience to use. In order to solve this problem, we designed and installed hot water circulating water system, the specific approach is to install a return pipe at the end of the hot water pipe network, connected to the water inlet end of the source, through the circulating pump and control system installed on the return pipe, the pipe water back to the hot water to ensure the water heating, open the switch point don't emit too much cold water can use hot water, and water.
