ᐅ Is it better to install the heat pump inside the house or outdoors?

Hello everyone,

we are currently considering the advantages and disadvantages of installing the heat pump either in the basement or outside in the garden.

Our architect has simply planned to place the heat pump behind a retaining wall in the garden.

- What are your experiences?
- What are the approximate cost differences?
- Would you recommend installing it indoors or outdoors?

The lot is 450 m² (5400 sq ft), with the house including a double garage occupying about 140 m² (1500 sq ft). There would be enough space in the basement.

Thanks

Hello,

we also have an air-to-water heat pump combined with a mechanical ventilation system with heat recovery installed in the basement.

Right next to the technical room is our guest room. Between them there is a standard concrete basement wall and two regular interior doors.

In the guest room, the unit is no longer audible (even with the door closed).

Of course, it is also not noticeable on the ground floor and upper floor.

As a layperson, I believe that installing the unit indoors or outdoors does not make a significant difference in cost – the additional effort inside the building is probably balanced out by the savings from not having to run piping all the way into the garden.

Regards,

Dirk

I just hope my neighbor doesn't have a motorcycle!!

If the installation is in the basement, is it located outside the thermal envelope? And is it mechanically ventilated through a duct?

If I remember correctly, Dirks’s basement is insulated all around. Aside from that, if the equipment is moved to the basement and the basement is used solely as a utility space, the heating and ventilation room still needs continuous insulation.

We place them in the corner, with the supply air on one side and the exhaust air on the other side through a light well. We didn’t want any on the outside due to space and appearance.

Could you please explain this a bit? I don’t understand the reason. – Thanks

Heating systems must be located within the thermal envelope.

However, insulation can also be applied in utility basements.
