Hello all!

I am the (co-)owner of an apartment in a multi-family house built around 1880 - the classic with gas floor heating, 3m high rooms and decorative facade. My family and I are naturally concerned about how we will heat in the future - as CO2 neutral as possible, of course.

From my point of view, the heat pump (HP) is the only sensible technology for heating, also and especially in existing buildings. It could even be worthwhile today if the consumer price for electricity were to drop to a tolerable level. Especially if you produce your "own" electricity. For people like me, however, this electricity cannot come to any significant extent from photovoltaics (PV) on my roof alone. Because there is too little space and the roof does not belong to me alone (co-ownership share).

We therefore urgently need a solution to be able to use "self-produced" renewable electricity from the surrounding area or from anywhere in Germany at producer prices (with a low transmission fee) for the HP drive. This would incentivize citizens like me to invest in my own PV (or wind power).

  • Is there any news on this topic that I am not aware of yet?
  • What are the reasons, if any, why this is not massively implemented (so far)? Who is possibly putting the brakes on this?
  • What are the reasons against the idea?
  • Who is familiar with the current legal situation, and/or knows what the planning for the future looks like?


Many thanks in advance
Frank

PS: Another delicate point is the issue of noise protection in existing buildings - there is often a mood against air-source HP because they are supposedly too loud.
On the one hand, according to leading experts (e.g. Mr. Miara from Fraunhofer ISE in Freiburg), there are possibilities to reduce the noise emission into the whispering range, but the current distance regulations may still be too restrictive for very narrow buildings, as it is often the case e.g. in S-West. Again, it would be appropriate to question the current regulations in order to advance climate change!
