Use:

Designed mainly for compact solar systems of the YL and HX series (non-pressure type). It is used for automatic topping up of water in the tank directly from the water supply network.

The maximum cold water inlet pressure is 2 bar. In the case of higher pressure, we recommend using a reducer.

 Design:

The assistant tank is a device that is designed to automatically top up the tank without overflowing. When using hot water, the water level in the tank will also lower. The float located in the tank will open the water supply from the water supply network. When the tank is full, the float closes the inlet valve.

The assistant tank is mounted on the pipe from the bottom (thread Rp 1/2'').
