Hello I wonder if someone can help me with this : we just moved to a new home which has an old UFH on the ground floor and first floor , but it is not working in the first floor , just learned today the the UFH we have called "Kee Triple Tube UFH" (no manual handed to us from previous owner)...

Hi, we have UFH in our conservatory. The front panel of the JG aura unit got detached accidentally. I've clipped it back on and while it still seems to have all the settings and the little flame icon comes on as expected, it doesn't seem to actually fire up the pump and heat the floor. This...

Hey there We purchased and installed engineered oak flooring as part of our living room renovation a bit over 12 months ago. The flooring was installed over a screeded wet UFH system using Bona R848 Flexible wood adhesive. The screed was given plenty of time to dry before we installed the...

Hi, I've been a plumber (not heating engineer) for 9 years now and finally bought my first home. As my first project, I decided to install a warm water UFH system. I've decided on Mapei Latexplan Trade for the screed which will be aprox 20mm thick. The data sheet states max 11mm per coat...

We’ve an open plan kitchen/diner/social space, that, as you can see, has a lot of glass. It carries the same thermal delights as a conservatory. Scorchio in summer, freezing in winter. It measures about 8x8m. The area has WarmUp UFH covering it, but I’d have to sell a body part to fund...

Hello, I am new to this great forum so first of all apologies if this has already been covered somewhere else. Here goes: I have a WB Greenstar 8000 Life boiler for all my radiators in the house. This is controlled by a battery operated, 2-wire Nest-E which was installed by the plumber at the...

Hi, I am planning to install a wet system in the next week or 2, prior to screed arrival for my new kitchen floor. Having done quite a bit of googling, I can't seem to find many impartial places of advice as to what's a half decent and not too pricey ufh system for approx 28m2 in a single...

We have painted floorboards throughout our victorian terraced house. We are planning an extension which will make the back of the house a very large open plan space (roughly 7m x 7m). Without much available wall space for radiators, UFH looks like the best way to heat it. I've noted that there...

Hi guys have 24v myson ufh manifold system set up with 2 zone with actuators. I want to control the zones with nest thermostats I have a cat 5 at the thermostat so that sides all good but I want to know what I need to run from the nest junction box to the manifold. Can anyone help? Cheers

Hi all, Can anyone help with question. I am laying some new insulation and electric UFH and need to minimise the floor build up. So far I am laying a layer of DPM, 50mm PIR cut to fit and then was planning on placing a 6 mm cement backed tile back board the UFH mat and then tile on that. I am...

Hi, some years ago I had wet UFH installed in my conservatory. It was just chopped into the existing Y plan wiring and plumbing. The problem being that when UFH demands the CH/HW runs and vice versa. We have put up with it but now as we are spending more time at home it needs fixing. The best...

Hi all, So I have some spare GA4100 celotex after using it for between the roof rafters. I should have enough remaining to provide a 100mm installation floor base and 75mm screed. Is GA4100 safe to use with ufh? Will the compression be too weak or will the foil cause issues? Ideally I would...

Hi, Just swapped all my thermostats to DT90E's (6 in total) and wanted to know if I should change anything in the installer menus as per my setup. The old thermostats were 3 wire (Live, Sw-Live and Neutral) and the new ones I've wired up with just 2 wire (Live and Sw-Live). I have a Nibe...

I have a fully operational 2-zone wet UFH system in the ground floor of my house. Suspended floor with PIR boards between joists, pipe laid on top in a S&C biscuit screed. Builder ran the flow and return for one of the zones under the joists of the cupboard under the stairs. The stairs go...

Wondering if you tilers could advise please? I will be laying a kitchen floor, 28sqm. Tiles are limestone, 600x400mm. 12mm thick. What would be The recommended trowel notch size for these tiles? I intend to stick a decoupling mat on the screed first, as I’ve got wet ufh. Would a 6 or 8 mm...

Evening all. Looking for some advice on a wet UFH install. I have a SCU209LED-TM wiring centre, which helpfully has no terminals for a 2 port valve (which is installed on the flow to the manifold). Link here: https://underfloorheatingexpress.com/amfile/file/download/file/6/product/277/...

IMG_20201025_164001 by AndyCW62 posted 29 Oct 2020 at 9:37 AM I installed this UFH system 15 years ago. Sorry about the embarrassing pipework. But it's worked all this time, although it has a leak somewhere so has to be re-pressurised every month. I want to fix this, so I'm looking for obvious...

IMG_20201025_164001 by AndyCW62 posted 29 Oct 2020 at 9:37 AM This brass component is leaking. I can't find anything that looks like it online to try to get a replacement. The top bit looks like an automatic air vent, but the body? Any help identifying this would be appreciated!

Hi, I am not even sure if I have a problem or not. I have had underfloor heating installed but the manifold creates a whirring / humming sound when running. The guy who installed it says that is the noise they make. I am not sure if this is truly the case and he can’t be bothered to sort it. I...

Hi DIYNOT I've searched this forum but not found anything matching my current issue, so please kindly help me. I have a property with wet underfloor heating, a REHAU system with 4 zones each with their own REHAU Star 20 thermostat. These are basic analogue dial thermostats. My intention is to...
