I have just read a study on the life cycle costs of a 12-unit residential building.
Alarming!
The cost per ton of CO2 saved was more than three times higher for the standard EH40 compared to the building energy regulation / building code.
Although this study focuses on a multi-family building, it could, to some extent, also be applicable to a single-family house.
According to the study, especially higher costs for maintenance, repairs, and component replacement negatively affected the economic efficiency.
Cost per ton of CO2 saved
Building energy regulation / building code: 2,171 €
EH55: 4,718 €
EH40: 7,523 €

Ball valve filter included or another type of sludge separator/magnetic/magnetite filter device for the secondary circuit as a requirement. a) What does this have to do with the Building Energy Act versus EH40?
b) What does the sludge separator have to do with the heating system? It is simply installed in the water circuit to prevent deposits, for example in the sight glasses of the flow meters...
You can install the same in gas, pellet, district heating, and so on.
Marketing this as maintenance for the air-to-water heat pump is "interesting," but it has nothing to do with the topic.

My nephew is building barely 100m (330 feet) away, and they are just interested in one thing or another. What you write sounds less like interest and more like simply being "against" it.
Even though your own house isn't all that different in content?!

I was talking about my place... Yes, just a standard air-to-water heat pump.
I don’t understand what difference you think there is relating to the Building Energy Act, EH40, etc.?!

No, it is exactly as I described.

Presenting this as maintenance for the air-to-water heat pump is “interesting,” but it is unrelated to the topic.I’m not trying to “sell” anything; I just wanted to point out that you do have filters in your system that need to be maintained (cleaned or replaced). And these should (hopefully) be checked and cleaned during maintenance as needed. You have to do the same for any other pump-based, water-circulated heating system, and of course, this has nothing to do with the Building Energy Act versus EH40. There are no maintenance-free products in this field.
