ufh

Hi all, I'm new in here. So I'm working on a tiny house for myself and currently designing the CV & warm water supply system. I'm an engineer myself, but CV, electrical and plumbing are not my core expertises, so I was trying to seek for a professional advice here in the Netherlands where I'm...

Hi folks, I want to replace my Thermo Sphere UFH thermostat with a Tado unit so it can be controlled using Alexa. This is the original unit: https://www.thermosphere.com/products/heating-control/programmable-thermostat And this is the Tado one...

I have a Grundfos UPM3 Flex AS pump for my UFH system. The lights on it are as follows: LED 1: Flashing green maybe every second LED 2: off LED 3: Solid yellow LED 4: Solid yellow LED 5: off I understand the yellow LED's indicate the speed/performance setting it is set to and I can change this...

I purchased a infrared thermometer to monitor the surface temperature of my floor with the UFH turned on. I have been monitoring it for a few days in the same spots and recording the data every 2 hours during the day. It seems I have a few hot/cold spots in locations I would expect there to be...

Hi, I have an unknown UFH system (not long moved in) that had to have the blending valve replaced due to a leak. I was worried that this would have introduced air into the system so now am looking to refill/pressurise the system (the emergency plumber just did the blending valve and said it was...

Hi all, hoping for some help/guidance on this one. I've got a UFH system downstairs that had to have the blending valve replaced. It was a fairly bad leak so Im assuming the system will need topping up/bleeding but the plumber that replaced the valve didn't do it. Obviously google search...

Good afternoon all, as part of a major refurbishment of my dad's 90 m2 semi-detached bungalow I am considering ripping out the existing suspended wooden floors throughout (some of which will have needed re-packing anyway), adding insulation, UFH pipework, and screed. It seems simple enough as...

I have a Vaillant ecoTec plus 618 boiler. The minimum heat output of the boiler is 4kw. I have UFH downstairs with 5 zones. Some of these zones are very small, like the utility room and the study. I think the UFH manifold is set to around 32/35°C. The house is a well insulated new build and...

Thought I'd clean out magnaclean filter on my combo boiler (intergas rapid+ 32Kw) Was a complete new install 3 years ago. The system had inhibitor and from what I remember a biocide for the UFH. There was hardly any crud on the magnet, but the grey strainer was slightly green stained bit like...

Hi wondering if anyone can help we have 11 zones of under floor heating which are linked to 3 separate thermostats. the plumber is different to whoever laid the underfloor so he can’t figure out which actuator / wire links to which thermostat so at the moment each thermostat heats up the...

I spotted this dark stain on my wood floor around 3 weeks ago, last time the underfloor heating was on was in December. Yesterday I switched it on again and it seems to be getting bigger. The stain is dark, no cupping or crowning, no sign of water or moisture. Any ideas whether it's a chemical...

Hi, so 6sqm (3m x 2m) of downstairs hallway, with front door as well as doors leading to: toilet, living room, kitchen, under stairs cupboard and then the opening to the stairs. We used to have a small rad but it got removed due to an underground pipe leak. Since then that hallway has been cold...

Hi all, I recently (4 weeks) ago had tiles laid on an anhydrite screed floor. I am now able to put the UFH on 'minimum' for one week and then slowly increase the temperature. The TMV on the manifold has 20 deg as it's lowest setting (20 - 70 is the range). However, my stat is sitting...

I have an uncommissioned wet underfloor heating system in screed. Yesterday the joiner was screwing into the newly tiled floors and may have potentially screwed into a UFH pipe (on the borderline of pipes). The pressure gauge on the UFH manifold was showing around 1.5 bar and dropped to around...

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...
