DOMESTIC HOT WATER CONNECTION

Pressure reducer

If the water mains pressure is greater than 6 bar, a pressure reducer

calibrated to 4.5 bar must be fitted.

Safety unit

The tank safety unit must be ACV approved and calibrated to 7 bar.

The valve discharge must be connected to the waste water disposal

system.

Domestic hot water expassion tank

Installing a domestic hot water expansion tank avoids any risk of

overpressure due to pressure surges and also makes sure that

there is a always water flowing through the safety unit when refilling

the domestic hot water tank.

Hot water circulation

If the tank is located a long way from the point of use, then

installing a closed recirculation circuit ensures that a faster supply

of hot water is always available.
