Hello,
we have purchased a semi-detached house from a developer. In total, the developer is building 8 semi-detached houses and one detached house. All the semi-detached houses will have a split water-source heat pump. Our semi-detached house has one gas line, and we were offered to use this line for a gas heating system with solar without extra cost.
The semi-detached house has a basement but no finished attic. The living area is about 130m² (1,400 sq ft) with underfloor heating installed throughout.
Which option should we choose, or which one is more economical considering the running costs?
Best regards,
AndiTanja

The heat pump is definitely the noisier option.Repeating it over and over doesn’t make it true that _all_ split systems are necessarily loud. Also, the general term heat pump covers a wide range of equipment, much of which is installed indoors 😉Regards, Bauexperte
Hello Bauexperte,
Curly did not write that at all. He only stated that heat pumps are generally noisier than gas boilers. I would agree with that as a general rule without hesitation. A gas boiler produces no noise outside the building. You will _always_ hear an air-to-water heat pump, even when installed indoors and with very high-quality units. Whether the noise is bothersome is a personal judgment, but the sounds from fans and airflows cannot be denied.
Best regards,
Andreas

Bieber081520 Dec 2016 21:38I agree with that but would like to point out that combustion systems (including gas boilers) also produce noise. This needs to be evaluated on a case-by-case basis. In the basement, it doesn’t matter, but if it is next to the living room, some people might find it disturbing. With air-to-water heat pumps, the noise is typically generated outside.

As he rightly pointed out, a boiler—or more precisely, the burner—also produces noise, usually inside the house. If the heat generator is located in the basement, the residents typically notice it less, but if it’s installed at ground level, it’s usually more noticeable.
I hope we can agree that "perception of noise" is a very personal matter. For some, even a whisper is too loud, while others (like me, for example) can easily sleep well even at an airport 😀
Best regards, Bauexperte

And I would also say that this applies universally and I fully agree with it.

markus270321 Dec 2016 06:38We have installed a new gas boiler in the utility room, and even when the burner is running, I have to stay very quiet in this room to hear anything at all. So I believe new units are quiet.
