Hello,
we are about to purchase a single-family house and plan to renovate quite a bit. In addition to a new heating system, the radiators will be replaced with underfloor heating. However, I’ve been wondering how to best carry this out. The house has a living area of 170m² (1830 sq ft), and besides the partially installed tiles, the screed layer would also need to be removed. The latter would involve a huge amount of work and significantly increase the costs, so I am considering whether it’s possible to install the underfloor heating by milling channels directly into the existing screed without removing it. Are there any other options? Since the doors will also be replaced, a slight increase in floor height is not a major concern.
What else should I keep in mind? How would the heating efficiency behave if the installation is done differently than usual? Any advice would be greatly appreciated!

I posted this topic in the wrong category. Could a moderator please move it to the heating section – thanks.
Since the heating system will also be replaced, could you tell me which heating systems or manufacturers you have installed? I am interested in brands known for durability, reliability, and good service (possibly with longer warranty periods). I plan to meet with several heating installers over the next few days or weeks, but I want to familiarize myself with the topic first. To know where to start in this broad field, I would appreciate any good advice here.

If raising the floor level is acceptable, why mill out the surface? That would mean losing the insulation beneath the underfloor heating, which I consider essential.
Removing the screed is quick and easy, though. We did it ourselves, and with two people—including carrying everything down 66 steps—it took just one day for 60 square meters. Cost: 200 euros for the container. However, I would only recommend this in basements or ground floors if there is no insulation underneath or if the ceiling below cannot be insulated. For upper floors, it seems too much effort. In those cases, it’s better to install a dry system, which requires a build-up height of only 4-5 cm (1.5-2 inches), including 3 cm (1 inch) of insulation. If no insulation is needed, a thin-layer system with a build-up of 1-2 cm (0.5 inch) is sufficient.

Hello,
we have 170m² (1830 sq ft) of area that needs to be removed. I don’t think that will be very easy. I can’t really judge the insulation situation. How much did the new screed cost you? The upper floor should be renovated as well, since all the rooms are located there. Our kids (2 years and 6 months) will also get a separate playroom, and underfloor heating would definitely be a good idea there. I don’t need underfloor heating in the basement. The three radiators don’t bother me since I don’t spend much time down there.

if you combine panel radiators with underfloor heating, you need to set up two separate heating circuits or purchase new radiators for the basement.
A panel radiator either requires a significantly higher flow temperature than underfloor heating or a considerably larger surface area to deliver the necessary heating output.
