Energy saving

Here you can find ideas on how modern radiators and control systems can help you make energy saving in heating.

Heating costs account for the largest part of our electricity consumption in detached houses. For the consumer, it is noticeably difficult to determine which heating system is most efficient and how you can make energy saving in heating and cooling. It is well known that a heat pump has a good COP value at low temperatures. But that is not enough. Underfloor heating gives a lower COP value together with a heat pump than, for example, hydronic radiators do. This in itself does not automatically lead to lower electricity consumption. Decisive is also how the heat is regulated and what heat losses the house has.

The ideal room temperature: does 19 °C suffice?

European governments recommend setting the thermostat to 19 °C to battle the energy crisis. But will this lower room temperature suffice to keep us comfortable?
