Efficiency class B is great for an existing house. Almost everything must have been renovated, which is good. Then the financing depends on how much you want to prioritize the house financially.
And is there a reason why someone would leave money on the table in a sale?
I’ll quote myself with my question - since apparently some energy work has already been done, I would ask myself if there is still some catch somewhere? Or is it a sale within the family circle or something like that?
The problem with the story is as follows: Oil is bad and must no longer be newly installed. An obvious replacement energy carrier is gas, but that has also fallen out of favor. Accordingly, you have to be prepared that in a few years someone will come and expect you to install a heat pump when the heating breaks down. Heat pumps in old buildings with radiators are not an inexpensive combination. Either you then renovate the house (energetically, underfloor heating -> new floors everywhere) or you make sure to install a gas heating system before the deadline and postpone the problem. What about the pipes for water and electricity? Are they already new?
I have to stand up for the heat pump. My sister recently installed an air-to-water heat pump in a house from the 70s, with radiators. Under the advice of an energy consultant. Sure, you don’t have 28°C supply temperature there, but they replaced the windows, haven’t insulated the building envelope yet, and it all actually runs quite smoothly, the electricity prepayment with the heat pump tariff is also kept within limits. They also have a lot of photovoltaic panels on the roof.
what did the photovoltaic system and air-water heat pump cost your sister in total after deducting the subsidy? A financial advisor would definitely be better here than the energy consultants….
So you have to be a bit of a businessman …. I’m still considering photovoltaic as a hobby and a bit of idealism, but a heat pump, no matter how I look at it, just doesn’t pay off …
Search term ARD Mediathek heat pump is a nice contribution about an old building heat pump with €400 per month electricity costs for the heat pump …..
Well, it is already becoming interesting now, depending on how high the gas price is. In my house, I achieve a VLT of 41° at -12° NAT. With radiators. Currently, assuming an annual performance factor of 3, I come to ~8 cents/kWh gas from when it would be worthwhile to switch to a heat pump.
