Hello everyone,
I’d like to briefly introduce our house project here. The goal is to exchange ideas with you on various topics and possibly create specific threads for detailed subtopics. Since we haven’t signed any contract yet and only have two initial rough quotes, I can’t provide details like heating load calculations at this stage. Thanks for your understanding.
Now for the first rough plan:
- Single-family house with about 170-180m² (1830-1940 sq ft) living space
- Bungalow
- Only the ground floor will be occupied
- Geothermal heating with 2 boreholes, each 80m (260 ft) deep, and a Nibe S1255 unit
- Floor slab insulation with glass gravel
- 36.5cm (14 inches) exterior walls made of Ytong masonry units
- Ceiling insulation using Ytong ceiling elements (maybe too expensive!?)
- Household of 2 people (likely to increase to 4)
- Decentralized ventilation (I’m not very satisfied with ReglerAir window units)
- Photovoltaic system on the roof, 7-10 kWp, without battery storage
- Triple-glazed PVC windows
I would appreciate your initial assessment and feedback.
Budget: Moderate, two incomes; total costs for the complete house (excluding furniture and kitchen) should not exceed 400,000 euros.
I will provide more information later.
Best regards and thanks for your feedback!
Peter

(Roughly speaking, ground-source heat pumps tend to last longer than air-source heat pumps because the equipment of a ground-source heat pump is usually installed indoors in a dry, temperature-controlled basement or utility room. This naturally helps increase its lifespan.)
Our air-source heat pump is installed indoors in a dry basement.
I would remove targets like KfW40 (significant standard exceedance) and similar ones. Trying to be middle-income/-wealthy and at the same time eco- and technologically avant-garde just doesn’t fit. When it comes to heating systems and such, you should keep in mind: the more high-tech the equipment, the more skilled the designer and maintenance technician need to be. Better medium-tech than high-tech — but incorrectly sized. You can talk a lot about what is supposed to be the latest trend, but it only helps if you actually do it — and that’s exactly where the "bottleneck" is, whether the plumber Krause from Bahnhofstraße is skilled enough for that. Controlled residential ventilation — whether single-room or centralized — in my view: if heat recovery is involved, it makes sense to “pool” all the rooms and have a central control unit manage the more complex processes. For simple airing/ventilation, however, in my opinion, a less networked system is better, allowing smaller units to operate standalone, which ultimately makes it easier to adjust or replace them modularly. And last but not least: whoever provides subsidies always pursues goals/interests that don’t necessarily align with those of the subsidy recipient. Money often simply serves the purpose of making arguments sound more reasonable.
