Hello,
after several years, we have finally found our own home.
The house was built in 1981 and is still in good condition, so we could actually move in right away.
There is a gas heating system and radiators in place... however, we have been "spoiled" by underfloor heating for years.
Now we are trying, as non-experts, to weigh the pros and cons... which is not so easy.
I think IF you decide to go for it, it should be done before moving in. Because once you live in the house (with 4 people), it only gets more complicated.
One point we can’t quite assess: does underfloor heating save enough energy to be worthwhile? What kind of purchase and installation costs should we expect?
My husband and father are skilled DIYers and could do some of the work themselves.
The total living area is 186 m² (with either just the ground floor or ground and first floors with about 65 m² each being relevant).
By the way, the house has a basement.
What type of underfloor heating would be recommended for retrofitting? I don’t know the ceiling height at the moment, but it was neither especially high nor low.
A very important point:
According to calculations, the house has an energy efficiency rating "G" with a consumption of 217.2 kWh/(m²·a).
Can anyone comment on this? What does that mean in practical terms?
There are double-glazed wooden windows installed, and I think replacing them would also make sense to avoid heating the garden...
We will probably hire an energy consultant to take a closer look at the house and provide advice. But I appreciate any help you can give in the meantime!
Regards,
schnie

I wouldn’t do that, simply because it would mean losing the insulation under the underfloor heating. This results in significant heat loss. In the dry system, there is at least 25 mm (1 inch) of insulation within the 45 mm (1.8 inches) total build-up height, which isn’t huge but still something. If the build-up height is limited, you can always use a thin layer system with only 10 mm (0.4 inches) build-up height, which is still better than milling, as old tiles or similar coverings don’t need to be removed.
