underfloor heating

Hi, We are renovating our house - its currently been gutted and we are thinking of putting Wet Underfloor heating in the whole house and currently weighing up the options. The ground floor will definitely be UFH (concrete floor so will be 100mm celotex + pipes + screed + flooring.) and we are...

Hello, Long story short: I am about to complete the purchase of a 3-storey house with underfloor heating (wet type). I'm currently trying to delay completion (due to complete tomorrow - Wednesday) because I suspect the builders (it's a new build) have put in standard underlay, not one suitable...

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...

I want install underfloor heating (UFH) and, apparently, because of the wooden floor boards we can’t use an electric UFH system, so we have to use a water system. But I don’t have a gas boiler to make hot water. There are electric boilers which apparently- according to google- will be ok for...

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/...

Have started renovating our house. We will be removing our LPG gas tank and ancient boiler to be replaced with an Air Source Heat Pump. As part of the renovations we'll be adding insulation in the roof, floors, walls, and doubling glazing windows. The company installing the ASHP have run a heat...

I've had electrical underfloor heating in the bathroom for 4 years and its been working perfectly. We went away for a couple of days and I set the Devireg touch to holiday mode so that it would come on when we got back. When we returned the RCD that supplies the underfloor heating (and the...

Hi, I am planning to put underfloor electric heating in Kitchen (8m2 - 1120watt) which seems fairly straight forward with my current DIY skills. Just need to confirm if I can run the power to electric heating (using thermostat) via 3 pin plug in one of the available socket in the kitchen...

We had a small weep on the flow meter side of an Uponor underfloor heating manifold. When I tried adjusting the flow, the weep turned into a flood! I shut down the pump and isolated the CH from the UFH and tried to remove the flow meter. It is the older black plastic meter with the yellow...

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...

Hi, We have a large village hall that we've installed UF heating in - wet system, covered in 75mm concrete screed. We don't have the sufficient drying time so looking to put down a liquid DPM ahead of an engineered timber floor (all flooring, underlay etc is UF heating- compatible). We'd been...

We have had Cozytoes heating matt laid and tiling done. They have come to install the Touchscreen Timerstat and they have realised they forgot the Probe/sensor that lays under the tiles amongst the matt. I know, cowboys, plonkers, not paying for it etc etc. However is it possible to fix this...

Hello all. Just in case one of you knowledgable people understands the intricacies of flow and return planning I'd like to ask for your advice. I've just ripped out most of the old ground floors in my house and laid underfloor heating. I've laid a new flow and return from the existing...

I have a wet underfloor heating system installed between joists in a 1930's house. The heating system itself works. The issue is with the subfloor.... The builder installed insulation between the joists, then clipped the pipes to the insulation as seems to be the standard approach. He then...
