Hi everyone.
A slight conundrum im hoping to get some educated advice on from people who actually know.
Ill be having the whole of my downstairs dug up in order to install insulation (none present) with a 75mm screed on top. Ill then have a wet system underfloor heating installed. My...
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...

Hello,
I have a piped underfloor heating system in the kitchen. The valve/mixer/pump unit is under the stairs.
It has a number of settings and a digital display. Settings include PP1, PP2, CP1, CP2, I, II, III, Auto, a number followed by W, and what looks like a night mode setting.
When I...
Hi
We have an UFH system part of the house (large kitchen / dinnner and utility room) and then Rad system for rest of house (10 rads).
We have noticed in this recent cold weather when both UFH and Rad are on (ie thermostatic driven) the UFH is robbing all the hot water and not getting round...
Hello all. First time posting so apologies if this is answered elsewhere.
I am close to completing a purchase of my first flat, an ex-council place from the 1960s built in the usual concrete slab and brick.
At present there is some ghastly pipe work for the radiators sprawling round every...
We had a wet UFH system installed a couple of years ago. Two weeks ago we had vinyl tiles laid. The instruction from the flooring guy is to start the UFH at 5 degrees and increase by 5 degrees per day until we reach a comfortable temperature. Also, instructions from the flooring company read...
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...
Hi - I little insight and guidance would be much appreciated.
My wet UFH was installed over a year ago by a qualified heating engineer, he went through all stages and did the pressure test as well, everything has been working nicely without any issues.
Now here is the unlucky coincidence - I had...
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
The UFH feels a bit patch in a few of the rooms so investigated the UFH controller...
What's this red stuff and should I be concerned about it?

Hi guys,
I have a set up with rads upstairs and UFH downstairs. I have installed the manifold for the UFH along with 2x Honeywell 2port values, one near the manifold and the other on the radiator side. I will be using Nest 3rd gen thermostats to control both the upstairs radiators and...
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...

So I posted a while back regarding my 300ltr unvented cylinder not seeming to keep any volume of water hot for very long.
Could it be the system boiler is not powerful enough? I have approx 220m2 of underfloor heating and the hot water cylinder’s . Does anyone know if Worcester Bosch Greenstar...
I'm looking for flow control valves to fit 2010 Rifeng FN5C manifold (fine-thread?).
Is there an alternative out there?
Hi all, I hope you're keeping well in this madness!
I wanted to ask a (probably stupid) question. I live in an apartment with underfloor heating, I've pictured what I can of it as I'm sure that'll make more sense than me trying to describe it.
During summer, I rely on a mobile aircon unit and...
We have a Worcester 30CDi boiler with a joule thermalstore 2.0 (gas and solar) with a Giacomini heat exchanger supplying hot water for our wet underfloor heating and our domestic hot water. It is a system we have inherited but one that does not seem to work as intended. The underfloor heating...
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...
Apologies if its already been covered. I've been asked to quote on a heat only with a solar compatible unvented, the existing system is 10mm microbore gravity fed to rads. I'm confident of the conversion and have my gas safe and G3, I've also been been asked to provide an outlet for, and install...
Hi,
Hoping someone can comment on whether what I see happening at my UFH manifold is OK, or whether there is cause for concern. I'm not an expert on underfloor heating, Our system was fitted about 10 years ago and has worked flawlessly with zero issues all this time.
As you can hopefully see...
Hi folks, hoping someone can help with a problem that's been perplexing me since just before Christmas..... I have a wet underfloor heating system installed in 2003 and manufactured by Underfloor Direct in NI - Now out of business. It's one of their triple tube systems and hasn't given me much...
