underfloor heating

Hi All, First time I've ever posted on a forum. I was wondering if anyone can help me please. I've had a new heating system installed for a couple of years now but have an issue with our underfloor heating, connected to a Nest thermostat, probably the wrong thermostat to use but this is the...

Hi Guys I'm currently starting a new UFH business in Scotland and was looking for some insight from locals on there experiences with other underfloor heating companties (Installers And DIY enthusiasts) in Scotland more specifically. What services or products are lacking/what you would like...

I seem to have what must be a common problem when using underfloor heating with a boiler however I haven’t managed to find a standard solution online. The boiler cycles at a high frequency due to the difference in boiler power compared to what the underfloor heating manifold will accept. Setup...

Hi, can anyone recommend suitable replacements for WLTA-19 2-wire room thermostats? Two of mine have stopped working. OJ electronics no longer makes them, and they haven't been able to identify any replacements. The manual for my WLM Hydronic control system (also OJ, and also discontinued)...

I know nothing about building. At all. Our new orangery floor with underfloor heating was screeded a month ago. The lift and slide doors were put in today and fit flush with the screed. But the vinyl tiles are going to add 5mm to the height of the floor leaving a trip hazard at all the doors...

We have underfloor heating on the ground floor of our house (wet underfloor heating system). The upstairs is radiators. Both work off the boiler. We are finding that when the thermastats downstairs and upstairs are both set to heat the whole house, only the ground floor underfloor heating gets...

I have a Devireg 550 fitted to control our under floor heating in the bathroom. However, the controller seems to have stopped working and is not displaying the screen settings correctly or switching the heating on. How easy is it to fit a new controller? Do I need to buy the same type, same...

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...

Hello, I've recently bought a house that was build about a year ago. It has underfloor heating (wet type, running off an air-source heat pump). The other day I noticed the low-level underfloor vents had water around them, as you can see in these photos. 20190101_141831 by hellopaul2 posted 9 Jan...

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...

Hi All, What would be the correct setup for combining wet (primary) and electric (secondary - for summer use) underfloor heating. We are installing a wet room on a concrete slab and will be insulation about this and then Screeding. The screed will contain wet underfloor heating pipes, the...

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...
