Hi - I'm extending my kitchen/diner and want to install UFH. Its extending by 50%, so will have half existing concrete floor and half new floor. The floor in the new bit is yet to be done. The cost of digging out the existing floor is a LOT - I'd like to avoid this if i can. A couple of companies I've seen advertised lay UFH into existing concrete floors by cutting channels and laying the pipe inside. The house was built in 2002, so the existing floor (should) be reasonably well insulated. Example companies: https://www.outsourcedenergy.co.uk/in-cut-underfloor-heating/ and https://www.jk-gb.com/jk-in-ground-ufh.php Has anyone had any experience of this method?

Hello, just trying to get my head round wet UFH in our conversion: The concrete is rough and unlevel in places so I'm hoping the screed will even things out, there is approx 200mm available in some places, but it varies. I'm planning: 10mm slate floor 65-70mm screed 100mm PIR The electrician has put the ring main on the floor so need to tuck the DPM under it. Is this ok touching the PIR? I read EPS can degrade plastic?? DPM ?? 10mm sand blinding?? or EPS?? Which sand is best? original rough concrete slab with a slight slope Which diameter of UFH pipes and which spacing is best to be the most flexible? Going to start with a Willis heater and save up for ASHP, but might need a boiler . Thank you!
