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...
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, I am trying to see if anyone recognises the brand of this underfloor heating manifold? I think it's about 22 years old. I'm trying to get more details to see if I can change the faulty actuator. Any suggestions welcome. Many thanks, Mark
Hi all, sorry a very stupid question from a newbie. I think some of my actuators are not closing the valves fully, so there's flow even when the heating is 'off'. Is there a way of checking/adjusting these? Can I just pull them off?
Should I instead just tighten the nut at the top (the...
Hi Installed UFH Manifold, pump, Valve etc, connected to a Saswell scu209led-tm1 Connection Box. On the terminals marked "com" and "no" going to the Boiler. Which terminals on a Grant Vortex Boiler do these 2 connectors go too?
Thanks in advance
Hi - some advice would be appreciated.
We are doing a refurb and are having water based underfloor heating installed.
The top layer will be 15mm engineered wood (floating).
Our builder has done things in a backward way so I need advice on what is the best solution given the circumstances...

Hi everyone, we have a 1920s house with solid brick walls. The small front carpeted lounge (1.9 combined tog of underlay/carpet) with its own UFH circuit is struggling to get to 20 degrees. The UFH pipes run under about 5m of LVT to get to the front lounge.
My question is, can I boost the...

Hi All,
We're been living in a new build property for the past 2 years without any obvious heating issues. We've an underfloor heating system that's split across 4 rooms, and is driven by a Daikin ASHP.
I've occasionally had to take the actuators off in order to release stuck pins after...
Greetings PF members,
Does ufh operate similar to normal central heating, as in demand, switched, satisfied etc? We’ve been having an issue recently, in one of our propertie, whereby the bedroom was staying hot even though all thermostats were off.
Boiler is a Combi, property is a well...

Hello
Underfloor heating installed in 2019 - no probs at all. Suddenly stopped working yesterday.
Thermostat is starting the pump, and lights come on. Pipe is very hot at point 1 - and cold at point 2
I have also noticed a leak at point 3
My theory is the motorised valve has broken - and...

The (rather sparse) manual with the controller that was supplied with my UFH (Hettaj describes the start sequence as - when demanded by the stat - valves open then pump runs.
As the programmability of the stat is very basic, I’d like to replace it with a smart controller the same as I use on...
Hello my hearing pump failed over the weekend and a new Grundfos Ups3 was installed to replace Geundfos UPS 15-50. Hot water and central heating were reinstated however as soon as the UFH was turned on the downstairs radiators went cold but the UFH became warm. I have turned everything off and...
Hi Guys
Im after any advice or if someone can recommend a good heating engineer in Thanet ?. I had a Wundafloor manifold installed for our groundfloor and new extension (currently 4 zones running) and im having problems with the whole system now and the plumber is ghosting my calls.

Evening all, I’m hoping somebody can help.
I have a wet speed fit UFH system, that controls 9 loops on the ground floor, each with a separate zone thermostat, flow valve and actuator.
The problem I’m having is when the main programmer (which controls the entire system), is left on (I.e...
Had a contractor come out today for in-floor heat not working. I have 2 zones each with Rehau manifolds supplied from a single pump and neither zone worked. Contractor felt the pump had failed and replaced it only to discover that the system still did not work. After much consideration...

Hi , I’ve just bought a house and there’s a big towelrail on one of the radiators, it looks really ugly and no use to me , I want to remove it and wanted to ask if it is ok to remove the towelrail and put blank cups on ? Would it affect anything else with heating?
I'm the homeowner of a heat pump + UFH installation, 2 floors with 1 manifold on each floor and a common pump. On both floors each circuit has the same problem: whenever a zone asks for heat and the motorized valve opens there is a some loud knocking going on (see video). In the case of the...
Just wondering if there are any issues with adding water to a UFH via the boiler filling loop… reason being wanting to flush out some gunk from a loop and ventilate but don’t have access at the moment to proper hose connection adapter so I can plug mains water at the manifold.
Was thinking to...
