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.
Current set-up

Hi. I have underfloor heating controlled by these actuators. One of the behr actuators is stuck on. Can anyone help advise how to turn it off? The newer one on the right is easy to remove and see the pin. The other two don’t seem to have an easy method of removal. Can anyone help?
Hi. Really strange one. Our underfloor works lovely. But once it clicks off, it stays off, resolutely. This can be either from the zone thermostat or, strangely, after we've showered using water for a megaflow tank. It's speedfit manifold but I think problem might be with JG wiring...
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...

Hi I have a Pulsar underfloor heating manifold with a leaky thermostatic valve. Plumber has managed to stop leak by tightening nut but this is 2nd time it’s leaked through ceiling in few months so was hoping to renew. However plumber been unable source a replacement/ equivalent as I know Pulsar...
We’ve had a UFH system installed as part of our home renovation which is run alongside our existing radiators. Some of it is in rooms with LVT flooring which means we’ve got to be careful with water temperature (floor temp limits are set, but can easily overshoot if water is too hot).
Our...
I live in a property where underfloor heating was already installed by a previous owner. No manual was left, not even sure of the model/setup of our system (other than the fact that it’s a wet system linked to my boiler/central heating system & I can see these pipes behind a cupboard). It is...
I have looked at the S-PLAN wiring diagram (standard) for my new UFH/DHW system, but I don't think it offers me the best use of the new heat pumps resources, given i want to run the heat pump at low temp for a long time during sunlight hours only. Instead I came up with different control plan...
Hello, I am not sure about the boiler as well as heat pump. Please tell me which one I should put in to heat my home.
hello newbie diy-er here looking for some guidance please :)
gas boiler (downstairs) was connected to underfloor heating pump and valve (attic, along with hot water storage tank), coming on with the hot water
the wiring between the two has failed - cable was exposed to water leak - so now I...
I am doing some work for a client which involves moving some pipe work for the underfloor heating. They would like it moved the adjacent wall so they can install a washing machine in the cupboard. I have included a picture below of the fixtures and the walls.
Question is, can it simply be moved...
Hi guys,
I'm having trouble with a newly installed UFH system. There are 2 manifolds, one with 5 loops, the other with 9. Both are made by Herz, model no 1732007. Pump is a Wilo Yonic Para something something. Boiler is Vaillant Elo Block 14.
My trouble is that setting the TMV to its minimum...
Hi All,
I’m installing an ufh system using procrate and 16mm ufh pipe. The procrate is laid on top of insulation but I’m finding that at each bend and return the pipe is either pulling out of the procrate or the procrate is lifing up. What am I doing wrong? This is the 3rd system I’ve installed...
Any idea where I can get a mixing valve the same as the one in the image, mine has a very slight leak.

Hi all,
I've previously been helped on here by kind people so I'm tackling my next challenge. We have a GSHP (installed by previous owners) that supplies a buffer tank. That all runs OK.
The heating pump and manifold actuators are 'controlled' by three OJ Electronics WLM3s (one master and two...
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 guys - hoping someone can help...
Have a 12 yr old Wunda 2-zone wet underfloor heating system which is starting to fail (zone heating up despite stat being off) and a generally old and inefficient thermostat system.
Difficult currently to get anyone to come have a look at it, managed to get...
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...
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...
