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!

Why? To move away from oil. Solar thermal can be omitted. There is already a circuit with a buffer tank (@TE: that’s correct, right?). It is quite easy to integrate a heat pump with that. Yes, it might “cost” an additional controller. No one offered to keep using the old tank for me. There were many arguments: voiding the warranty, heavily scaled, and so on.

There were many arguments.Arguments or just pretended arguments to sell you more? It's a rhetorical question.

I’m increasingly uneasy about the global and political developments regarding oil and worry that it will eventually become financially unviable.Just replace oil with electricity in your statement. The same concerns now apply to electricity prices. Additionally, there are high upfront costs for a heat pump, a relatively short service life, and other significant challenges.
There are growing reports of excessive electricity consumption with heat pumps, cold homes, and a shortage of qualified technicians who can properly install, adjust, and maintain heat pumps.
There is nothing wrong with an oil heating system.

Electricity generation does have a CO2 component (in the energy mix), but it is significantly lower and will continue to decrease in the future. So the gap in price increases will keep widening.

There are also high investment costs for a heat pump, Oh no. Starting at €20,000 from a professional company for the monoblock BEFORE subsidies. It’s not that extreme anymore.

Relatively short lifespan of the heat pump What is meant by "relatively short"? The typical lifespan is nowadays stated as 20 years. Even for commercial use, a depreciation period of 15 years is recommended these days. Poor heating system design with frequent cycling shortens the lifespan, but that’s also true for many other devices or machines (the best example being cars mostly driven on short trips—as combustion engines, not electric).

Further not to be underestimated problems. Which ones exactly?

There are more and more reports of horrendous energy consumption with heat pumps, cold apartments, lack of and unqualified specialists who can properly set up and maintain a heat pump. Wow, quite a mixed bag of issues. I also hear more and more about exorbitant heating costs in old houses with oil heating. But the lack of qualified specialists doesn’t mean heat pumps are bad. Just because skilled workers to build a Maybach are missing doesn’t automatically make the product bad.

The gap in price increases will therefore continue to widen.You obviously have prophetic abilities.
The specific problem with heat pumps is the poor and completely outdated grid infrastructure in Germany. There are already talks of planned forced shutdowns, unreliable electricity supply, and even bankruptcies of energy providers. This issue will naturally become more relevant with the increasing number of heat pumps and electric vehicles. I won’t even start on the rising electricity prices.
The politically driven CO² taxation in Germany, on the other hand, is purely ideological. I am calm about future governments on this. Especially if the AfD becomes part of the government, which will likely abolish all this CO² nonsense again.
And it has always been like this. Oil prices have repeatedly become cheaper. The advantage is that I can store it and buy it in bulk. This is not possible with electricity or natural gas. And in 2021, I believe heating oil was somewhere around 30 cents per liter. CO² or not.

You obviously have psychic abilities.No. But I understand the subject. I can read laws. And there are also market laws that prices are subject to (by the way, the CO2 tax is a European law, not something invented in Germany, so it cannot simply be repealed there). Buchsbaum066 schrieb:

Have you followed the polls? Oh right, they’re all fake...Man, why am I even writing so much just because an uneducated AfD supporter with no economic knowledge claims random things...
And avoids addressing points because he realizes he wrote nonsense again.
