FAQs – Answers on heat pumps

What is the benefit of a photovoltaic system with heat pump?

FAQ arrow

Self-produced solar electricity is cheaper than electricity from the grid. That's why homeowners with photovoltaic systems should consume as much solar power as possible. With a heat pump, you optimize your own consumption because you can better coordinate production and consumption. If you use solar power for your heat pump, you will additionally reduce electricity costs and save even more money than with a heat pump without a photovoltaic system.

How does a heat pump work?

FAQ arrow

Heat pumps work on the same principle as refrigerators, the Joule-Thompson phenomenon, but in reverse: the refrigerator extracts heat from its interior to cool, the heat pump extracts heat from the earth, groundwater or air to heat. Depending on energy efficiency, two to five units of heat are generated from one unit of electricity.

Is a heat pump worth it?

FAQ arrow

For the environment immediately. With a heat pump, you reduce the CO2 emissions of your heating system by 98 percent. For your budget in the medium term.
