ᐅ Costs of Underfloor Heating in a Renovation? How to Remove Screed

Hello everyone,

In the near future, I might be purchasing a house built in 1970 that will need renovation. I have a question regarding costs and some basic details:

The house has a basement (partially heated), a ground floor, and an attic, with a floor area of about 100 sqm (1,076 sq ft). It currently has a gas heating system (installed in 2002) with standard radiators, mostly located under the windows. I would like to install underfloor heating throughout the entire ground floor.

Question:
If I remove the existing screed myself so that the heating installer can start work from the concrete slab, essentially like in a new build, what kind of costs should I expect? The heating in the basement and attic should be retained.

Thank you in advance for any information.

Best regards,

Hello everyone,

This question is currently on my mind as well. It’s about a semi-detached house from 1970. In 1992, the heating system was converted from oil to gas. We would definitely like to have underfloor heating at least on the ground floor.

When researching the topic of retrofitting underfloor heating, you come across several providers offering installation without removing the screed. It seems that the space for the underfloor heating pipes is milled into the screed.

Whether with or without removing the screed: Are there any experiences with retrofitting underfloor heating? Can anyone share information on costs and/or the practical feasibility of installing underfloor heating afterwards?

Best regards
Ferique
