Retrofitting heating

Hello everyone.

We have the opportunity to buy a house from 1950.
At the moment, the house is still heated by a coal stove.
The living area is approximately 90 m².
Can someone give me a rough estimate of how much the retrofit of a heating system would cost?

Thanks

Regards Frank

Hello,

....Can someone give me a rough estimate of what retrofitting a heating system would approximately cost? ...

10...25 T€, who can reliably quantify that?
For older existing buildings, it makes sense to pursue an overall energy concept.
Sometimes it can be more economical to condition the building envelope (reducing heating energy demand) rather than investing exclusively in the system technology.
In addition, existing buildings sometimes pose considerable financial risks regarding the building structure.
Initial "bargains" often turn into nightmares later on!

Best regards

According to our experience (built in 1936), the new heating system (gas heating and radiators in all rooms) cost about €20,000. The problem from my point of view is different. If you open everything up to install the heating, it makes more than sense to also renew the entire sanitary piping at the same time (+ approx. €15,000). I won't talk about the advisability of electrical renewal when everything is open right now (approx. €15,000).

These are our values for a 1938 house with medium new equipment.

According to our experience (born 1936), the new heating system (gas heating and radiators in all rooms) cost about €20,000.

This is certainly not transferable to any existing system renovation!

..If you tear everything up to install the heating, it makes more than sense to also completely renew the entire sanitary piping at the same time (+ approx. €15,000)....

Correct, a one-time, slight "bleeding" burdens overall less.
Personally, I find existing renovations, where you can practically "tear everything up" (core renovation), much more accommodating than significant, partly restrictive boundary conditions. In the latter case, usually only a more or less justifiable compromise remains, depending on the individual case.
Sustainable existing renovations represent the highest level regarding expertise (building structure, system technology)!

Best regards.

That is certainly not transferable to any renovation of existing installations. v.g.

If you understand German well, you surely understood that I did not write "That is the case with any renovation of existing installations," but rather "According to our experience with a house from 1936."

You partially give good hints here, but your repeated assessments and your know-it-all attitude without real added value may lead to you soon being the only one writing here. And that would be a pity for the forum. It also lives from diversity.

....."From our experience with a house from 1936".....

What added value does this create for the OP?

.....but your repeated assessments and your know-it-all attitude without real added value....

Your assessment is unfortunately somewhat one-sided. "Know-it-all attitude" is unfortunately predefined, since I come from the field and the industry.
There is hardly a post that I could not comment on. I simply lack the time for this, so I limit myself to just a few.
Some answers from anonymous advisors without any professional training even cause financial damage to those seeking advice. The unfortunate thing is, there is no liability for this!
The assumption that sustainable, reliable value retention could be obtained for free is mistaken, unless you live in socialism.
"Free" advice can at best be afforded by sellers who swindle inexperienced builders to their disadvantage with colorful advertising gimmicks.
Since I am not only active as an MEP planner and energy consultant but also as an expert, I could write a book about this!

...can lead to you soon being the only one writing here.

Sometimes less is indeed more!
More is not always better, and rarely truly reliable!

Best regards
