ufh

Hi all I'm having a kitchen extension built and getting UFH installed - the quote for that is £2900, which sounds about right to me. Eventually, I plan to install UFH in the rest of the house myself, so I've asked for a quote for putting a four port manifold on the first floor too as part of...

has anyone attempted a "diy" to replace the flow meters and valve pins on a warmafloor UFH manifold ? also how easy is it to just replace the whole thing as I'm seeing manifolds for under £200 and wondering if its worth buying parts or just replace the whole thing but I'm not sure how straight...

I have an existing 20+ year old UFH install but don’t have the original designs or design Flow Rates per circuit. I have measured up the rooms and using thermal camera can see the circuit spacing is approx 150mm in Spiral layout. I’ve flushed all the loops and cleaned all the flow meters, but...

My partner and I just started building a 4mx7m rear extension. We plan to knock two walls down so the extension is part of a large open plan space along with the current kitchen/dining room (also 4mx7m). We've already decided to install wet UFH on the new part, but we are struggling to decide...

Wondering if anyone could shine some light om my flooring? Ive got amtico spacia, ontop of an electrical ufh system which has been set into a screed. Its been done by a professional but after 2 weeks the floor started bubbling, and the mat that the cables sit in has buckled in several areas of...

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...
