My normal supplier has phoned me today to say they cant supply the grooved cement board overlay system(18mm) till end of September.
Can anyone recommend any suppliers that may stock it ? need 230m2. Will need to make some calls tomorrow and find another source if possible.
Hi. Hoping for some advice. Yesterday I did have an authorised tech round whom fitted a new control board and electrode/cable and my DUO TEC Compact+ 24 GA came back to life but things are not going as expected and unfortunately I am in Lithuania full time since lockdown and do not speak...
Hi all,
I wanted to ask a general question about an underfloor heating system our plumber is proposing and if this solution will be sufficient to heat the rooms.
We have only a woodburning stove (15kW nominal output) that heats our open plan lounge/kitchen/diner directly (6.5kW from the...
I have Heatmiser slimline thermostats installed in most rooms which have water uhf zones. They work fine but I’ve always thought the current temperature reading was a bit off. I confirmed this today by placing a few internal room thermometers in various places and it appears the Heatmisers are...
Hi, I'm after some advice on converting my current CH system to Wiser smart system. In particular, looking for advice on whether I can use the Wiser Hub without using Wiser's specialist Underfloor heating controller.

Hi,
I have a combi boiler that supplies hot water to two ufh manifolds. We only have ufh and no radiators. I am trying to find the most efficient way to heat our home. What would your recommendations be on the following ways to set our system up.
A) Set the ufh mixer to max so it isn't doing...
I have two adjoining cottages, each with an identical UFH system downstairs. Both been going fine for around five years.
But for the last few weeks, one of the systems doesn't seem to be running most of the time. Essentially the UFH does "work", in that I can turn the thermostat right up, and...
Hi all,
I have a Heatmiser UFH installation, 7-8 years old now. This week we noticed that a few of our heating zones were not warming up, even though the thermostat was showing the flame symbol. They were working fine last winter. I knew from when I looked at the installation in the past that...
Hello, I’ve had some work done in my house to redo a kitchen and replace damaged floors and while doing this I was convinced to install W-UFH since the floor was coming out anyway and there were some joist issues in the Victorian property.
Previously I had about 9 radiators in my house, 2 of...
Just moved into a house with 5 heating zones, 4 of which are underfloor and connected to a Heatmiser UH2. The 4 UFH zones each have a thermostat - one old dial type and 3 Heatmiser Slimline programmable stats.
A few teething problems with a zone valve fitted the wrong way round but generally...
I have some actuator pins that are stuck (in the open position). I assume that the best thing to do is just to replace the entire valve, but is there a quick temporary fix - I.e. lubricating and hitting with a hammer (yes I know it's not the most professional solution)
thanks
Hi, we had underfloor heating installed about 15 years ago. Some of the actuator valves are now leaking and we need to replace them. I'm trying to source some that fit. The plastic caps which came with the originals had the 'Watts' brand on. I've tried ordering a couple of the most common valves...
Hi,
I am appealing for some advice and direction on replacing the heating control system in my house. Ill try to describe as best I can. Looking for a bit of info as not having much luck with trades.

Downstairs I had a 12 port Hetta underfloor system installed by a plumber. Upstairs I installed an 8 port Hetta system myself using the existing pipework which had an old system on. Both systems are now fully Hetta with exactly the same components on (wiring centre, manifold, actuators...

Hi folks, I’m in need of some sound advice.
We have recently had a ground floor extension and have had underfloor heating (company: JK UFH) installed throughout most of the downstairs. We have a few rads still left downstairs and the entire upstairs is still heated through rads.
We have a...
Hi,
I have an 1904 redbrick 2,500 square feet house.
We have UFH on every floor. 3 Floors
House is reasonably well insulated but far from perfect.
Would there be any point in installing a "air to water" heating system that could link into my existing UFH??
Hi,
I have bought a house that has Uponoor water underfloor heating. It was running ok but the recent cold snap has resulted in me being unable to get my rooms warm enough despite the boiler churning through plenty of gas.
A little googling and poking around with a torch reveals that there may...
