Frank198127 Jun 2014 16:45Hello everyone.
We have the opportunity to buy a house from 1950.
Currently, the house is heated with a coal stove.
The living area is approximately 90 m² (970 ft²).
Can someone give me a rough estimate of the costs to retrofit a heating system?
Thank you.
Regards,

Hello,
For older existing buildings, it makes sense to pursue a comprehensive energy strategy.
Sometimes it can be more cost-effective to improve the building envelope (reducing heating demand) rather than investing solely in the heating system itself.
Moreover, older buildings can carry significant financial risks related to the building structure.
Initial "bargains" often turn into nightmares later on!
Best regards

Umbau-Susi28 Jun 2014 11:10Based on our experience (built in 1936), the new heating system (gas heating with radiators in all rooms) cost about €20,000.
In my opinion, the issue is different. When you open up everything to install the heating system, it makes a lot of sense to also replace all the plumbing at the same time (an additional approx. €15,000).
I won’t go into the benefits of renewing the electrical installations while everything is exposed, but that would be around €15,000 as well.
These are our figures for a 1938 house with a mid-range renovation.

..If you open everything up to install the heating, it makes a lot of sense to renew all the sanitary piping at the same time (+approx. 15,000€).... Correct, occasional, minor “bleeding” results in less overall stress. Personally, I find renovations where you can practically “open everything up” (full gut renovation) much more straightforward than those with significant, sometimes restrictive, boundary conditions. In the latter case, you usually have to accept a compromise that is more or less justifiable depending on the individual situation.
Sustainable renovations of existing buildings represent the highest level of expertise regarding the building structure and system technology!

You provide some useful tips here, but your repeated judgments and know-it-all attitude without real added value might soon leave you as the only one posting here. That would be a pity for the forum. It thrives on diversity.

.....but your repeated evaluations and know-it-all attitude without real added value.... Unfortunately, your assessment is somewhat one-sided. "Know-it-all attitude" is pre-defined here, as I have professional expertise and come from the industry.
There are hardly any posts I could not comment on. I simply lack the time for all of them and therefore limit myself to just a few.
Some answers from anonymous advisers without any professional qualification even cause financial harm to those seeking advice. The unfortunate part is that there is no liability for this!
The assumption that sustainable, reliable long-term value can be obtained free of charge is mistaken, unless you live in socialism.
“Free” advice at best can be offered by sellers who take advantage of inexperienced homeowners to their detriment, using flashy marketing gimmicks.
Since I work not only as an MEP (mechanical, electrical, plumbing) planner, energy consultant, but also as an expert witness, I could write a book about this!
