Hello everyone,
we are planning a single-family house of about 140m² (1507 ft²). We have been recommended an air-source heat pump from Valliat. We do not have a basement, and the utility room is 8m² (86 ft²). The heat pump with the water storage tank takes up about 4m² (43 ft²).
It would be possible to install the heat pump in the attic (the ceiling is concrete). Is this efficient enough? Or is the connection to the outdoor unit too far away?
The system is: air-to-water heat pump geoTHERM VWL S

It’s not just the air heat pump, but also the water storage tank with domestic hot water preparation, solar panel (Vaillant VPS Allstor 1000), and the ventilation system.
The water storage tank is quite large... Then there is the air heat pump and the connections... It all adds up to a lot.

The air source heat pump has a maximum area of 1m² (11 square feet) and the water storage tank is under 1m² (11 square feet). The fan unit will be installed outside, or is it supposed to be indoors as well?
I would say this is a large, old system, and it has about 2m² (22 square feet).

VPS 1000 = Oval shape 950mm x 1195mm (37 inches x 47 inches) + connections,
GeoTherm VWW 6 1/2 = 600mm x 850mm (24 inches x 33 inches) + connections,
+ supply and exhaust ventilation system (wall-mounted unit),
with enough space it could be done with 3m² (32 sqft)... But I prefer to be on the safe side...

Hi,
Basically, with a lot of money, many things are possible! However, more is not always better! That means, of course, you can install the system anywhere in the house, but then you have to reinforce the attic ceiling more strongly. In general, all the system technology can be placed inside the building, which naturally takes up space, but also has economic advantages. Nevertheless, issues such as leaks, longer connection pipes, or possible noise problems due to positioning the system in the attic cannot be ignored. In this regard, the utility room is usually the better alternative. However, it is not uncommon to install the heating system in the attic; for gas condensing boilers, this is standard practice. There are also fewer reasons against this.
I am just wondering:
- What standard does your house meet?
- Who recommended this system concept to you?
- Did you hire an energy consultant, or did the structural engineer simply approve it?
Best regards!
