Need to know if the attached photo is likely evidence of a failed tanking membrane? Background... Recently bought the property and I knew the basement floor needed re-tiling as almost all were cracked. The tiles were laid over an electric underfloor heating system which, the previous owner had...

Hi, we had UFH installed dowstairs in our house recently, and I'm not 100% sure that it's connected correctly. I'd be grateful if someone could have a look at the diagrams and tell me if what the plumber did makes sense. The house is heated with an A2W Samsung/Joule heatpump. The buffer...

So I have a combi boiler and two zones, one is underfloor heating and the other goes around 9 radiators. There has been alot of black sludge blocking the heat exchanger the last few years. I am planning to get a filter on the system and I was recommended the Magnaclean Pro 2. However I dont...

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...

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...
