Hello,
we are planning to replace our oil heating system with a heat pump as soon as possible (with subsidies), and I would appreciate your help in understanding what the current costs might be and what would be considered overpriced. We do not have a quote yet but are in contact with a reputable company that also includes an energy consultant for the subsidies.
Our house has a living area of 130 square meters (1400 square feet) spread over 3 floors, plus a basement that is at street level on the downhill side due to the slope. The house was built in 1930 but underwent extensive renovation in 2008, including insulation of the facade and roof, new windows, replacement of water pipes and electrical wiring, and installation of solar panels for hot water. We have also installed a small balcony solar system. Due to large dormers, there is limited roof space suitable for photovoltaic panels.
Unfortunately, there is no underfloor heating, but radiators, some of which are quite old and probably should be replaced. There are a total of 12 radiators.
Our current annual oil consumption is about 1500-1600 liters (400-420 gallons).
I’m not sure what other information is needed to get a rough idea, so I’ll leave it at that and wait for any questions.
I hope you can give me a rough estimate so I can better evaluate offers.
Thanks in advance!

The oil heating system is from 1998, so it’s quite old.There are systems that have been running for twice as long.You can also apply for KFW funding.
If you want to spend little money, in my opinion converting to condensing technology is much cheaper and still allowed today. It reduces consumption by about 20–30%.
First, get some quotes. The companies will then inspect your existing system and know exactly what should be done.
Show us the roof surfaces.

Additionally, integrating thermal energy with a heat pump is expensive and complicated.

Also, integrating thermie with a heat pump is expensive and complex.I can confirm that.
But it is definitely beneficial if you use less electricity.

Show us the roof areas.But condensing technology still uses fossil fuels, doesn’t it? Here is a picture from above (the house with the solar modules is oriented north)

Isn’t condensing technology still using fossil fuels?If that is a deal breaker for you, then so be it.
I only wanted to show you what I consider a lower investment.
Despite the high costs, I decided on a heat pump and photovoltaic system.

I was just pointing out what I believe to be a lower investment.
Despite the high costs for the heat pump and photovoltaic system, I decided to go with them. We want to move away from oil or other fossil fuels as much as possible because their prices are expected to rise significantly and, additionally, they are simply not sustainable. Since there are currently subsidies available, we want to start the process soon. But we will see how we proceed with solar. We need to wait for some quotes and so on.
