Structural UFH boards - alternative to Omnie?


Del-inquent

Recommended Posts

As we need to replace most floorboards I was looking at Omnie’s Torfloor 2 structural boards. I like the fact they’re printed to stop idiots like me putting a screw through the pipe and also not needing to glue the cover plate down.

 

initial “rough” quote was £5k plus tax which although higher than we wanted wasn’t too bad. Then they sent the proper quote and it’s now suddenly £8.5k plus tax. 80% of that price is the boards. It’s £1.2k inc tax to put down standard 22mm caber without some pretty grooves routered in…

 

So are there any alternative but well thought out structural UFH systems that don’t take the piss on the board prices?

Trouble with all these systems is flow temperature required.  On the blurb on the web page it states flow temperature between 35 and 55. I used a similar sort of system in a very well insulated garden room, it needed a flow of 35 on a 12 deg day and room still wasn't that hot.  At zero I tried 45 and the room was at 16 degs after 24 hrs. Absolutely rubbish. There is just to much thermal resistance in the system to work well at low flow temps.

 

I would just steer clear all together. I ended up fitting a fan coil and now 33-35 degrees will happily heat to 22 when -5 outside.

 

Insulation insulation and more insulation required if on a ground floor. Look at a dry screed (pug or biscuit) system. You can DIY and everything and can come from your favourite builders merchant.

That was with the Omnie system? All the feedback I’ve read on them was about the quicker warm up and lower thermal resistance, which was what got me interested in the first place!

 

alternative is reds throughout but it’s a chalet bungalow with next to no wall space upstairs

Have you looked at heated skirting?  If you have plans they will send you a quote.

We did look at thermaskirt originally, I might even have asked about it on here, but Ive read very mixed reviews on its effectiveness.
