When it comes to heating methods, experience shows that recommendations differ in all forums.
We are installing a gas condensing boiler again because, in our personal opinion, this method is still the most effective at the moment. Conversion options to other technology are possible.
We have had many discussions about this. The majority in our neighborhood use gas condensing boilers.
There are also air-water heat pumps in our new development area. Meanwhile, neighbors have started arguing about them. The units are not as quiet as advertised, after all.
Only our property met the necessary requirements regarding boundary distances for geothermal energy.
I won’t mention the other methods now. Someone else can have fun with those.
