How to install the return pipe of the air source water heater

As shown in the figure:

1. If a return pipe is installed, the water pump of the return water system will start to work. It will pump the cold water remaining in the hot water pipe to the return pipe. , and then merged into the cold water pipe, so that hot water comes out of the water heater when taking a shower;

2. If there is no return pipe installed, a one-way angle valve must be installed under the wash basin furthest from the water heater. , when the return water system gets the return water signal and starts working, the cold water originally remaining in the hot water pipe is pumped directly to the cold water pipe through the one-way angle valve. In this way, hot water comes out directly when taking a shower. Extended information
