System Build-up
The system combines a gas condensing boiler and a heat pump (hydro-box) for space heating and
domestic hot water. Depending on the position of the 3-way valve, the gas condensing boiler can either
be bypassed or not. The heat pump can either operate or not, depending on the active operation mode
(heat pump only, gas condensing boiler only or hybrid (= heat pump and gas condensing boiler)).
