underfloor heating

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...

Hi all, I’m trying to figure out why the temperature on my water is getting so high that it cuts off my circulation pump from running (greater than 60 degrees). As expected, the thermostat triggers a notification to the control unit that then calls for hot water from the boiler (by opening a...

Hi, we have 4 electric underfloor heating systems in our house, all managed by 4 Thermotouch 5220/5226 thermostats. We recently had a solar system installed which is working brilliantly. When we turn on any of these 4 underfloor heating systems the power draw (regardless of area being...

Hi I've just moved to a new house and I’m looking to replace my current heating system controls with a Drayton Wiser smart system. I have an Ideal Vogue Max System 32 boiler with water tank, a basic Drayton thermostat that controls hot water on a timer and a Salus thermostat. I also have a...

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. I am new to underfloor heating. I am in a new build. I have two pumps feeding two manifolds connected in parallel and feeding two different ground floor levels. There is a hot/cold mix dial for each so supply hot water is diluted to a lower temperature as I understand. While balancing, I set...

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...

Good afternoon, I was hoping someone could help me/give me advice here regarding improving our heating system at home: We've moved into a house that we bought earlier this year and the boiler and heating controls were outdated so we upgraded the boiler to a Worcester Bosch Greenstar 8000 Life...

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 all, I am planning on doing a wet DIY underfloor heating install downstairs of my property. I have zero experience with the plumbing and electrics side of the install, I plan to get a pro in to hook everything up but want to ask a question to make sure I have not missed anything prior to...

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...

House is a 1930s semi-detached house that was gutted out and done up ~5 years ago. It's reasonably well insulated. It has a Valiant system boiler (gas) paired with a Joule unvented cylinder. The hot water is controlled by a honeywell timer, the heating side of it is left on permanently and...

Hi everyone, So I'm working on my own house and the plan is to install water based underfloor heating for the downstairs. Currently I have a suspended timber floor which appears to be in good condition (if not 100% level), I was wondering cost-wise if I'm prepared to do most of the work myself...

Hello All, I am in the middle of the extension and my builder is suggesting under floor water heating. We have block and beam floor put on. I am wondering if anyone can help me answer the following questions 1. Is it cost effective to put the underfloor water heating on? 2. How thick the...

I'm renovating a small 3 bed 70's semi-detached property, with ~50m2 downstairs floor area. modern double glazing, cavity wall insulation. No central heating currently, and i've opted for a Viessmann 35kW Combi (ASHP cost prohibitive, which is crazy!) I've opted to fit oversized rads upstairs...

Hi, I need some advice on what wet UFH system to get for our renovation of a 1970s 3 bed bungalow. The house had subsidence so in the process of fixing that the floors were dug up and replaced with the following construction: hardcore base, membrane, 150mm insulation, concrete finish. We're left...

Hi guys I am new to this forum, apologies if I'm posting in the wrong place. I have a question in regards to underfloor heating, I've received quotation from two places fastwarm and omnie. Which one you guys think will be better as the difference between them is about £500 in favor of fastworm...

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 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...

We are having our 1990 built bungalow extended and renovated. The new 150mm concrete subfloor was laid in October. The existing floor was stripped back to the concrete subfloor. The subfloor was lined with VCL with 75mm Celotex on the new subfloor and 40mm on the existing. Underfloor...
