What one should never forget when doing all the heating calculations are the ongoing costs and the hidden acquisition costs. For a gas boiler/pellets, for example, you need a chimney draft for about 2,000 euros, which you do not need with a heat pump. With pellets, there are also maintenance fees of 150 euros every year. And you also need electricity for all the circulation pumps with pellets or gas. And with pellets, you should actually count the space for the pellet storage as acquisition costs. With the heat pump, this electricity is completely included in the seasonal performance factor, and if you have a pump with less than 3 kg of refrigerant, you also do not need any maintenance. We were initially considering pellets or geothermal heat pump... Gas is not an option for us because we do not have a connection and we did not want a tank. We have now decided on an air heat pump, which costs about 10,000 euros less than the other two solutions. Because even if we might have 300 euros more electricity costs per year, from our point of view, it does not pay off compared to geothermal. Addendum: Gas, by the way, burns the cleanest among the fuels with the least CO2 emissions and the least fine dust. (Pellets are actually worse in this regard, it is only portrayed as "green" because trees can regrow)

If you have a gas connection, I would rather tend towards that. Low costs for the purchase, burns cleanly.

What about your ventilation behavior? Can you do without it?

There is a gas connection available at the street. At least in the summer, I will not be able to change my ventilation habits. We have cats, cat food smells, and I am allergic to cooking fumes, so I like to open the window immediately. I want to live in my house the way I want and am also willing to pay more money for it.

How about a controlled residential ventilation system then? You can only get more fresh air through permanently open windows and doors – which gets quite cold in winter.

Especially in summer, the ventilation behavior is irrelevant for the energy consumption of the heating.
