ᐅ Is investing in a heat pump really not worth it?

I have always been a supporter of green electricity and renewable energy sources, so I would like to have an air source heat pump for our own house. My husband is much more conservative about this, and we haven't been able to find common ground so far. Based on the current gas prices, he calculated that an air source heat pump would only pay off after about 15 years. He assumes purchase costs of around 10,000 euros. But is this rough estimate/calculation really accurate? 15 years would be too long for me as well... We have a solid construction with 170mm (6.7 inches) Unipor bricks and a 140mm (5.5 inches) external thermal insulation composite system (ETICS) / external wall insulation.

If you are interested in an exact price for a heat pump, have one quoted by a heating engineer. However, the price alone is not sufficient; the heat pump must be specifically designed for your house.

Thermal insulation of your home also includes using local climate data to determine a heat pump with an adequate coefficient of performance.

It is advisable to seek advice from a specialist engineer; although this involves a fee, you will receive professionally determined data for heat supply with a heat pump, including costs and payback period.

Your husband’s price estimate is actually correct; you will need to calculate within this price range.

I would have thought that a heat pump only makes sense starting from a certain house size.

That is also the case, which is why consulting a specialist is necessary. This includes thorough calculations and determining which heat pump can be used. A cost estimate is often provided as well.

I also sought advice, and it’s all too expensive. It only pays off after at least 15 years, which is a long time. So, for anyone who needs to watch their budget, a heat pump is simply too costly.

Heat pumps are relatively expensive to purchase, that is true. The other question I have is that with a heat pump, I don't need any other fuel. I only require electricity for operation. This makes me relatively independent with this energy source.
