Hello dear house building forum,
We are building a KFW55 semi-detached house with approximately 150m² (1,615 sq ft) of living space. The project is being carried out with a general contractor. During planning, it turned out that the proposed location for the air source heat pump (behind the garage, at the neighbor’s property line) is not allowed because:

We are building a KFW55 semi-detached house with approximately 150m² (1,615 sq ft) of living space. The project is being carried out with a general contractor. During planning, it turned out that the proposed location for the air source heat pump (behind the garage, at the neighbor’s property line) is not allowed because:
- The location is behind the building boundary line
- The required setback of 3m (10 feet) from the neighboring property is not met
Our general contractor has suggested the following options:
- Ground source heat pump, with additional costs of at least 15,000 EUR
- Exhaust air heat pump, probably no additional costs
- Where can I find reliable information about alternatives to outdoor installation of an air source heat pump? Which organizations or professionals could provide expert advice (possibly for a fee)?
- What is the difference between an air source heat pump and an exhaust air heat pump?
- Is an exhaust air heat pump even suitable for a KFW55 house?

When standing in front of the heat pump, the minimum clearance on the left side is slightly less (40cm (16 inches) vs. 60cm (24 inches)), so that might be more practical. But wouldn’t that violate the minimum distance to the neighbor on the other side?
I would talk to the general contractor to see if, due to the specific circumstances, a change of manufacturer and model might be possible.
The heat pump from @kati1337 is, as far as I know, a “standard” heat pump with a complete indoor unit. Maybe she can provide more details and name the model?

The heat pump from @kati1337 is, as far as I know, a “standard” heat pump with full indoor installation. Maybe she can add some details and name the model? Yes, we have a Tecalor THZ 504. I have written quite a bit about the unit on my blog (Chris and Kati build a house) and included some photos. It is installed indoors only.
It is a combined unit, an air-to-water heat pump and ventilation system, and it takes up about half of the utility room. But it is a good unit and we are satisfied with it. To be honest, it’s probably slightly oversized for our house (in terms of heating capacity). However, we are happy; in the first full year, the energy costs for heating, ventilation, and hot water were around €54 per month.
I’ve just joined in halfway through.
I don’t think any of the three installation options are particularly good.
Definitely not by the garage. Even if your unit is quiet, it acts like a sound funnel.
But generally, I wouldn’t want to have that thing on the terrace either.
Option 3 is still the better choice.
But as already asked, why not in front of the house? Did I miss some reasons for that? Where is the utility room?
With these options, I would also prefer an indoor installation.

It’s not allowed by the street because it’s explicitly excluded in the development plan. All attempts to discuss this with the local authorities were unsuccessful. Maybe it could be challenged. Since the heat supply via heat pump is explicitly desired, such a ban doesn’t really make sense. As if the street had to be the most attractive place in a neighborhood...
