Gas or heat pump? Experiences / Feedback

Insight is the first step to improvement.

Always only advertising for photovoltaics yourself, but presenting others' statements as false without arguments.

I myself also find photovoltaics + heat pump in a well-insulated house good.
Reasons for this are protection against rising energy costs and environmental protection.
But the payback period is often significantly longer than you propagate here, and as Bookstar says, the whole technology is also associated with risks regarding technical defects.

Fortunately, I started a thread ..... it's really not easy .

If I had the choice, which we didn’t have! Keep the gas!!! Heat pump only trouble

That didn’t work out with the insight after all...

Your facts are your opinion, nothing else. Gas runs without problems for 25 years and heat pumps are junk after 15 years. Well, surely you can provide the long-term studies for that(?). Maintenance costs for a heat pump? Aha, I wouldn’t know any, but gas costs a lot more to me.

A fact would be that gas is tried and tested and therefore reliable, you can’t really go wrong with it and gas costs are cheap. Heat pumps for residential use haven’t been around that long, there is still development potential. If the pump works properly, heating costs are the same or better with geothermal energy.

As of now. What happens, for example, if a CO2 tax is introduced? Then from the introduction on, no one will be thinking about installing a gas boiler anymore. No one knows how gas costs will rise – great dependence on other countries, etc.

Well, you could argue forever. Whoever can do the math and read up should do whatever makes them happy. If you have paid €40,000 for your gas heating for heating and investment over 20 years (or even €70,000 if the gas price develops unfavorably and burning is heavily taxed), I have just reached €20,000 with my heat pump+photovoltaic supply temperature. With my above proposal, I’d easily be at €0...

Maintenance costs are also many times higher.

I keep thinking about this topic, even though the house construction will only begin in a few years. What needs to be maintained on an air-to-water heat pump?

If you do it yourself (in my opinion) a ring trench collector combined with a Nibe is the optimum. Then a photovoltaic system as large as possible, e.g. 30kWp if it fits. Costs with BAFA funding and doing everything yourself then about 25,000...35,000. With that, you then have no heating/electricity costs and still make 200€ profit every month. (Roughly shown what is possible)

Yes, you are suggesting this now because you have it that way! But if a gas connection is available, then add solar: cheaper and more comfortable. Thinking about the above only starts when gas is not possible.
