ᐅ Air-to-Water Heat Pumps – Your Experiences (All Brands) / Types, Costs

Hello everyone,

We are planning to build a single-family house next year with about 160-170 sqm (1700-1830 sq ft), without a basement. It will have underfloor heating and an open living area. A fireplace is not planned. We want to install an air-to-water heat pump.

I would prefer a monoblock system since no refrigerant certificate is required for maintenance. Our utility room is planned to be large enough to fit a monoblock, but I would like to benefit from your experiences. Even if some of you have a split system, we haven’t completely ruled that out yet. There are now also combination units with indoor and outdoor components that can be maintained without a refrigerant license.

Here are my questions:

- Which air-to-water heat pump do you have?
- How long has it been in operation?
- Do you also have a fireplace or another heating option? (If yes, would you manage without it?)
- Have you ever needed to use the electric heating element?
- What is your annual electricity consumption for the heat pump?
- Have you encountered problems with very cold outdoor temperatures? (Electric heater, etc.)
- How "loud" is your heat pump? (Have there been any issues with neighbors because of noise? Or is it too loud for you?)
- Why did you choose your heat pump, and would you make the same choice now?

As you can see, I basically want to know everything you can share. I really appreciate any information!

Best regards!
