x-change® dynamic brine/water heat pumps

The x-change brine/water heat pump is the heat source in the “Kermi system x-optimised”. It uses a geothermal collector or a geothermal probe with a heat transfer fluid (so-called brine) circulating in it to extract thermal energy from the earth and converts it into heating warmth.

Heat pump advice

Sound level and sound insulation

With their exceptionally effective sound and vibration absorption Kermi heat pumps generate scarcely more noise emission than a ticking alarm clock.

Combining a heat pump with solar panels

It makes perfect sense to combine a heat pump and a solar panel system: Heat pumps need conventional electricity to operate – a solar panel system generates electricity from solar energy. And Kermi x-change dynamic heat pumps have an integrated solar panel interface as standard.

Which heat pump is the right one?

Large or small property, single-family house or multi-family house – which heat pump is the right one for your own construction or modernisation project depends above all on the conditions in and around the house. Some rough basic data and classifications help in the selection process.

Cooling with a heat pump?

Whether air-to-water, brine-to-water or water-to-water heat pump – heat pumps can also be used to cool living spaces if the necessary technical requirements are met.
