We have the maintenance done every year for our DV heating system with surface collectors. Price per maintenance €170 gross.

In the first year, there was too little coolant in our system, so only part of the surface was used. There were quite significant heaving and settling. I estimate that the complete surface was lifted between 20 and 30 cm and then settled again in spring. Last winter, I could not observe any visible heaving or settling.

Especially in spring, you can already notice that the growth is somewhat delayed. Snow remains on the grass longer and everything grows a bit later. I estimate that this makes about 14 days to 3 weeks difference in spring. The advantage is that you have to take out the lawnmower later.

You are having the maintenance done, okay, but does a tightness test actually have to be carried out? I have already read that the floor has lifted by 20-30 cm at your place, and I find that severe. But that was probably due to the missing refrigerant. Did the heating company actually pay for that themselves? I think you also have a heat pump from Heliotherm, right?

No, we do not have a Heliotherm but a Lüumel heat pump. We did not pay for the refrigerant itself, only for the maintenance.
