Frequently asked questions

Can radiators be used with a heat pump?

Yes. Radiators must be sized for a flow temperature of 45–50 °C. At this temperature, a room needs a radiator roughly two to three times larger than at 70 °C.

Can underfloor heating and radiators be combined?

Yes. Circuits that require different water temperatures are separated with a mixing valve or a dedicated circuit. In bathrooms, a towel radiator is often added to the underfloor heating.

Can underfloor heating be used for cooling?

To a limited extent. The water temperature is kept above the dew point to prevent condensation. If full cooling is required, fan coils or air conditioning are added.
