Heat pump and condensing boiler technology combined
The heat pump takes over the entire heat output for the building during the warm transitional period, i.e. during light heating operation. A boiler is only activated when hot water is required. Thanks to hydraulic decoupling, all consumer groups receive the volumes of water they require, regardless of the amount of water requested. The boilers can supply the missing energy precisely using condensing technology. At the same time, when outside temperatures are cooler, the heat pump first heats the cold system returns to 45 °C and the remaining energy is supplied by the boilers as mentioned above.
