air heat pump IWS GmbH

Hello dear experts,

we are still undecided regarding the heating technology. Should it be a heat pump, we have already shortlisted one. Namely the air heat pump from the company IWS GmbH. The model is called "Atria". The indoor unit is about the size of a fridge/freezer combination. It is supposed to work without problems down to -20 °C. The manufacturer has been producing devices in Sweden since 1973 and belongs to Danfoss.
The defrosting process of the outdoor module is demand-controlled and happens automatically. It is thus kept ice-free. Since we repeatedly read and hear negative comments about air/heat pumps, we wanted to ask the experts in this forum to have a look at the device on the page ****** and share their judgment (as far as possible) with us. The system is completed by a supply and exhaust air system with heat recovery.

For us laypersons, this all sounds good and plausible. Unfortunately, a small doubt still remains in the back of our minds.

It would be really kind if someone knowledgeable would take the trouble.

See you soon

Adrian

Hello,

...For us laypeople, it all sounds good and plausible. Unfortunately, there always remains a small doubt in the back of the mind.

What would that be?
Air heat pumps are as common as sand by the sea. The question about the device/manufacturer is absolutely secondary. Only when the complete calculations for the specific object are available does the choice of device or manufacturer come into play.
Here, the cart is always put before the horse. Typical layperson’s question.

Best regards
