Hello,
I'm looking at installing a new central heating system with UHF on the ground floor and normal rads on the 1st Floor. The design was initially to have at its heart an Ideal System Boiler and a Telford Tempest 500l Indirect Cylinder but I'm considering changing/modifying this design to...
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...
As above. Ideally it'd be less.
This might be the wrong forum for the Q. But the system is actually working fine. the system is in the 15mm insulation boards above a tar subfloor.
Are my next steps to start getting cavity wall insulation etc etc?
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 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?
I wonder if anyone can help me. My house has under floor heating but after having a new boiler fitted it doesn't seem to working as it should do. I wanted to get the system balanced but some of the flow meters are stuck and not all of the actuator/flow valves seem to be moving as they should. I...
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 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...
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...
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 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.
I have a water underfloor heating system installed that has never really worked. There were also radiators installed around the same time that also didn’t work. So basically the entire central heating doesn’t work. There is no air gap in the water pipes, I’m convinced there are some underlying...
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...
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 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.
