Connecting the heat pump to the heating system
Individual temperature control in each room and increasing volume of
internal water
This solution is used to control the temperature of each room, for example, where thermostatic valves are used on the
radiators in each room. The function of the heat pump is to maintain a temperature in accordance with the heat curve
(depending on outdoor temperature) in the 100 litre primary water storage tank. The water is then distributed from the
store to the heating system. This solution also allows the overall volume of the installation to be increased if the volume of
the heating system is inadequate, for example with one or two fan-assisted radiators.
This system design is intended to ensure that the heat pump is able to continue operating if the fl ow falls below 70% of the
nominal system fl ow.

* Mixed heating system
There is a possibility to control a second
heating system with a mixing valve. This
is recommended when a combination of
radiators and a fl oor heating system is
used.
