I've installed Vaillant air-to-water heat pump a year ago, and it has worked flawlessly so far (in the UK).
Valliant's pump is pretty quiet (I've heard PCs with worse fans) and uses a relatively benign refrigerant.
- microtonal 4y agoWe have a Nibe F470 air-to-air. Most of the time it's as loud as an old fridge. Not something you notice, since it in its own small room (where the gas furnace used to be). When it's freezing outside and the heat pump is working hard, it is louder, but you'd also hear the gas furnace under such circumstances. I think by and large, it's more quiet than the gas furnace we had before.
