You can read it this way or that. Not only as a question but as a recommendation. The intention is not immediately obvious but now you have clarified how you meant it.
First, read up on this in the forum. You are asking such a general question like "Is the red car good and cheap because my friends said so?"
Low heating costs are not dependent on a single equipment detail, there are many other things involved, e.g. building envelope, heating design, underfloor heating or radiators, own usage behavior
A fuel-efficient 1.0-liter petrol engine also has an immense consumption when installed in a truck ;-)
okay, that was not clear to me. but yes, I am still relatively inexperienced in that regard. I will see what else I can find about it in the forum.
1.) If it somehow financially works out, then a geothermal heat pump... Unless other reasons prevent this, e.g. soil conditions of the property, regulations regarding groundwater, general contractor objects if the general contractor is supposed to build.
2.) Air heat pump if point 1. does not work due to various reasons. Or low heating load of the house and/or in combination with a photovoltaic system. Although a photovoltaic system is never bad, except when poorly planned and implemented.
3.) In general, there are no bad heat pumps (whether air, ground, or water), only badly planned houses or hydraulics.
4.) Exception if it is not an extremely well-insulated passive house. Then never let anyone sell you a so-called air-to-air heat pump or so-called comfort air heating or whatever heating.
THANK YOU! that is a helpful overview. let’s see if a geothermal heat pump is even within the budget and if the building conditions also speak for it. what is so special about this option?
And also no exhaust air heat pump!
First of all, I want to say that you cannot generally state prices for the various options because it always depends on the conditions, etc. Basically, geothermal heat pumps are more cost-efficient in the medium to long term. If this option is not feasible for you, I recommend an air-to-water heat pump in combination with a photovoltaic system.
okay, thanks! the long-term aspect actually interests me the most. we would rather invest a bit initially if we can save something in the long run. do you yourself also heat with this system?

... and if you are a bit handy or find a decent plumber, you can also look around online for "Geisha." It is a Panasonic monoblock with a very good price/performance ratio. It is not as effective as geothermal energy, but as a layman, you can replace the heat pump yourself in one or two hours if it breaks down in 5 or 10 years. That will cost you at most around €3,000 for the heat pump.
Since no work on the refrigeration circuit is necessary, it is possible, but those who want to be on the safe side will take HB. However, Geisha should only be done by someone who has studied well, as the correct hydraulics, underfloor heating, and hot water planning are also required.
But Geisha should only be done by someone who has thoroughly researched it, as the correct hydraulics and underfloor heating as well as hot water planning are also necessary.
You should replace Geisha with any heat pump and someone with heating installer ;-) The DIYer gives more thought to the hydraulics and design of the underfloor heating than 90% of heating technicians. LOL
