What is the principle of backwater device?

1. Working principle of temperature control: set the temperature of the backwater device. Once the temperature in the hot water pipe is lower than the set temperature, the backwater device will automatically work, so if the backwater device is left on for a long time, it will be started every ten or twenty minutes. The only way is to turn it on once a day in the shower and turn it off after washing. This is semi-automatic.

2, the working principle of water control: backwater is an additional ripple switch, that is, once you feel a little fluctuation in the water in the hot water pipe, it will automatically start and stop working once, so you don't have to switch it every day after installation, and you won't worry that it will work circularly and waste water and electricity, so it is called automatic.

Specific introduction:

1, the backwater device is also called intelligent hot water circulation system. In cold winter, hot water is used at home. After the hot water tap is turned on, the cold water in the pipeline comes out first. Only when all the cold water in the pipeline is drained will the hot water come late. In this way, you will wait for hot water in the villa for more than three minutes or even five minutes. You not only waste water resources, but also waste time.

2. Install the backwater device. When hot water is needed, start the backwater device dozens of seconds in advance to realize "hot water can be seen as soon as it is turned on".

3. The backwater device is used together with the domestic hot water supply system (gas water heater, electric water heater, solar water heater and positive displacement water heater). When taking a bath, you don't need to wait for the cold water to drain. Through the automatic circulation function of this product, you can get comfortable hot water immediately after use.
