6. Hydraulic connection
The use of a circulation loop should be restrained. Such an installation may disturbs the stratification
inside the tank. This triggers more working cycles for the heat pump and the potential use of the
electric backup heater.
6.1. Cold water connection
No hydraulic device (stop valve, pressure reduction, flexible...) is allowed between the safety valve
and the cold water inlet of the water heater.
