Pleasure and understood re the slab. Engineered flooring is fine. Get your builder/heating engineer to work out what they expect the HW temp to be in the pipes and then speak to your preferred wood flooring specialist to determine what tolerances their flooring has. Go engineered, check how thick the flooring is and what glue/bonding/fabrication system they use and whether the estimated temp will affect them. Make sure you know the desired depth of flooring you want so that your builder/engineer can correctly calculate the temp. Thicker the flooring, higher the temp etc.
Note that the panel systems used by Continal can be laid on a slab, with the flooring directly on top, so still offering you speedier fitting, (no curing time as no screed) and the same control as a radiator system. Just cos you have a slab doesn’t mean you have to fit the pipe work into the screed or even need a screed at all....just remember that this may impact door thresholds as you may be saving as much as 60mm if you were planing on using a floating screed and then don’t. The panels are approx 20mm thick. Monsieur Le Grenadier I've not been everywhere, but it's on my list..... 2011 Puma 110DC - Corris Grey |

Hi Catherham,
We in the process of fitting UFH to ur kitchen and downstairs toilet, we had the same concerns as yourself, my friend owns an UFH company and carried out the install for us, we have gone for a manifold and control system from Robot https://www.robotunderfloorheating.co.uk/underfloor. We lifted our chipboard floors and exposed the beams to accommodate 50mm PIR insulation and heating pipes with an 80mm biscuit mix screed to joist level, this was then topped off using Knauf Brio 22mm thermally transparent screed boards. I called on one of my industry contacts to specify the correct timber flooring for our toilet as my wife wanted herringbone grey oak, they confirmed that high quality engineered timber flooring would withstand the temperatures and with the additional pipe loops installed would still radiate enough heat to keep the room warm. Let me know if I can help with any information Cheers John  Click image to enlarge 2014 110 2.2TDCi XS Station wagon 1971 Bowler Tomcat 88 4.2 V8 Auto 2022 110 D250 XS Edition - Gone 2024 110 D250 X-Dynamic HSE |

We built this place for one of my customers 7 years ago and got under floor on ground floor and 1st floor 25% covered in slate and 75% covered with engineered bamboo
 all on a biscuit screed between 2x1 battens at 400 centres  and it works perfect to this day

I have UFH in a converted barn. I have exceeded the specs to provide a good base, the screed is covered with Karndean (spelling?) flooring. Looks great, easy to clean and feels lovely in winter. 80" 1948
