MultiVal - Calorifier for bivalent heating

Calorifier with 2 heat exchangers (coil) for heating using 2 heat sources. The primary heat generator is usually a solar energy system. Any heat generator (e.g. heat pumps, biomass boilers, condensing gas/oil boilers) can be used as the additional heat source. Supplementary heating can optionally be provided by an electric heating element or an integrated heat pump (CombiVal WPER).
