ᐅ Heating system in the extension at the property boundary

Our current design includes an extension behind the carport at the property boundary to serve as a basement replacement room. It is intended to have direct access to the house. So far, I have received conflicting information about whether this room can also be used as a utility room (primarily for the heating system). Perhaps you can help clarify this. Is it allowed to install the heating system in this room? My current neighbor has done it this way, so I was somewhat surprised by the recent statement from a prefab home manufacturer saying that this would not be approved.

My only concern would be that in the current situation (heat pumps will be as valuable as gold in the coming years due to shortages), someone might break into the relatively inexpensive door and steal the heating system when I'm not around.
Maybe you should invest in a door that’s a bit more secure in the long run. After all, this door is protecting a system worth... probably around 40,000 EUR? 😉

By "inexpensive" I actually meant poorly insulated... thanks for the warning anyway ;-)
Anyone who manages to uninstall and transport this heat pump unnoticed would definitely win first prize at AGT.
Our heat pump from AI only cost 17K, including installation, back in 2021.

State Building Code RLP:

9) Buildings may be constructed directly on property boundaries or with reduced setback distances without setback areas if they meet the following conditions:

  • 1. Garages without fireplaces,
  • 2. Buildings and facilities for local supply of electricity, gas, and water,
  • 3. Other buildings without living spaces and without fireplaces,

provided that they are located on the property boundaries or within 3 meters (10 feet) of the boundaries and

  • a) have an average wall height not exceeding 3.20 meters (10.5 feet) above ground level,
  • b) have a length along the property boundary not exceeding 12 meters (39 feet), and
  • c) have roofs pitched at no more than 45º toward the property boundary; gable ends at the boundary may not exceed a height of 4 meters (13 feet) above ground level.

In other words, heat pumps used for heating are allowed, but anything requiring a chimney is not. Electrical and water installations are unproblematic.

[...] Only downside: If the router ever needs to be powered off (especially in winter), it means putting on slippers and throwing on a jacket (I could have moved it to my internal utility room, but didn’t want to because of the extra effort).

We solved this quite inelegantly: The router is connected to a simple timer switch that cuts power for 10 minutes at 3 a.m. Since then, no manual restarts have been necessary.

Why connect a router to a timer switch? If frequent restarts are required, the root cause should be addressed—not just the symptom! Those still using VDSL might face issues with the DLM, which automatically reduces the connection speed after regular restarts. My router runs continuously for months without problems.

I completely agree. In about 1.5 years, my router has only needed to be forcibly disconnected twice due to updates or disruptions. I didn’t have much choice regarding the router (well, I had a small choice since I opted for a business connection with a FritzBox Cable instead of a private plan with a low-quality router. My only provider is Vodafone with gas fiber/FTTH). I have occasionally had to unplug the router during firmware updates or longer interruptions. However, I certainly wouldn’t accept this if it were regularly required.

I wouldn’t really worry about someone removing the heat pump. The question is whether it’s even a good idea to install it there. My thinking was this: we planned for only a small utility room in the house (about 6 square meters (65 square feet)) with access to an extension (about 18 square meters (194 square feet)). The extension is naturally insulated differently and not heated. The system in the utility room takes up quite a bit of space in the 6 square meters (65 square feet), so I thought maybe it could be placed in the extension instead. Whether that’s allowed seems to be settled from my perspective. The remaining question is whether it’s advisable or if there are valid reasons against it. I’m not familiar with the subject and just want to explore the options before someone asks me afterwards: “Why didn’t you put that thing in the extension?”
