underfloor heating

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...

OK, so we have recently moved into a house which has underfloor heating installed throughout and generally it works really well. The system is fed from the hot water boiler. There are two manifolds, one for upstairs and one for downstairs. Both manifolds have pump which drives the water into...

Sorry, newbie here. If this should have been posted in the Electrics or Flooring section please feel free to move. The previous owners installed electric underfloor heating in our ground floor bathroom, we cannot live without it as our only other heating in our home is the log burner but the...

Hi. I have a Grundfos UF heating pump and it seems to be very slowly leaking around the connector over time then running down the back of the pump onto the floor. The nut looks to be about 50mm in size so was going to try nipping it up a bit with a wrench but it’s hard to get a grip with that...

Hi, Midway through refurb with some heating concerns. I’ve had UFH put in. Part of downstairs is concrete, insulation with screed over UFH. Nice and hot. However, 75% of downstairs is joisted. I was worried by builder and plumbers plans to put UFH in here. They’ve put insulation between...

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 all, We're currently renovating a Victorian house and are struggling a little with the kitchen floor situation. As we are in a tough spot financially we cannot afford to get any trades in at the moment so please no suggestions on that or i'll cry. As you can see from the picture half of...

Hi all Recently moved into a new property that has electric underfloor heating in a downstairs toilet. The controller is saying E1 but can’t find out the manufacturer of the controller to see what the user guide says (seller lost the user manual!). Any ideas who makes this controller? Looks...

Hi folks, I have a combo boiler and radiator system across the house. I would like to put underfloor heating in my existing conservatory, I would like to have water instead of electric because of the energy saving. Theres a radiator on the wall in the house next to the conservatory. I want to...
