Hi I have underfloor heating pipes installed in between joists for first floor. Wonder what anyone has used in the past for insulation between joists? Rock wool or Celotex boards? or any other insulation. Realise the celotex route will be more expensive. Thanks in advice.

Hi, We have had an extension built and are having the layout of the house completey changed so thought it would be a good time to install underfloor heating. I'm a boiler guy by trade but have never installed UFH but it doesn't seem too complicated. Firstly I assume that in the new extension...

As part of a renovation, our plumber installed UFH in the main ground floor areas, as we were having new floors laid. Rads were installed in the rest of the house. The UFH is in two separate zones (separate flow monitors for each). Therefore, a 3 zone system in total. The plumber left us with...

Hi Anyone got any tips for laying our 20mm PE-RT underfloor heating pipes into aluminium spreader plates (200 mm centres)? Specifically I'm after advice on how to get the pipe to be more flexible. The pipe is really stiff and very difficult to get it to fit around the bends. I'm going to try...

Hi, I've just moved into a flat with Devimat heating and am confused about the settings / display. 1. Should the mat switch off as soon as it reaches the end of the "on" time? This morning, I noticed that the Devireg 550 controller in one of the rooms was showing the heating-up symbol about 40...

Hello UFH people. I am about to install a wet underfloor heating system 25mm 8:1 screed over celotex between joists @ 400 centers. Seems to be the best fit for our project. I need to get the pipe work in soon so that the floor can go down. And then I’ll do a bit more research on manifolds/...

Ok. So I know that cost is a very subjective thing but I'm in the midst of a renovation - my first real project - and we're planning to tile most of our ground floor so to take the cold edge of the tiles, we're planning on installing electric underfloor heating. We've had a quote for around...

Hi, I'm planning to install a thermal buffer store (to prevent my combi cycling) as part of my UFH on a building control ticket. I'm a professional engineer, and feel competent to install it safely. However, I am unclear about part of the G3 requirements (so competency not quite there, but...

Hi, I'm a new member here, but have been floating in the background for quite a while now. I'm putting acoustic insulation and UFH into the floor of my first floor flat. I'm planning an approach inspired by an (acoustic) detail mentioned in building regulations document E, 3.102, which...

Looking for advice on UFH as well as general heating system. We have made the choice to get water underfloor heating in the middle of our refurb works for the kitchen. Rather than placing PVC pipes in plastic castellated floor panels, we will have them routed between joists and on top of...
