We have a large kitchen/dining area and I've measured the temperature. It's an interesting pattern... up and down.. and up and down... even though the thermometer is set at a constant temp. No night time set backs or anything like that... just inertia.
We have a GSHP and ancient controls (see...
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...
I have NuHeat UFH system, and this has no Thermostatic Blending valve on the heating circuit. (Heat Master II cylinder has pick up coil)
Nu-Heat System installed -
This means I can't run store above 60C due to risk of overheating UFH pipes.
I want to add a Thermostatic Mixing valve so have...
Hi,
I have domestic water based UFH - 20 years old. House is 100 years old with 5 beds. UFH everywhere.
Works okay but perhaps could be better. Top of house is coldest.
I have newish worcester boiler(Greenstar 8000 life).
System is on 4 different storeys, 5 manifolds and perhaps 18 loops...
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...
The following is a proposed very simple installation of UFH open/direct to an existing 1000 gallon fossil fuel hot water storage tank:
We are told that this won't work since the UFH pipework and pump are above the height of the tank, and therefore gravity will empty the UFH... But our...
Hi, we had UFH installed dowstairs in our house recently, and I'm not 100% sure that it's connected correctly. I'd be grateful if someone could have a look at the diagrams and tell me if what the plumber did makes sense. The house is heated with an A2W Samsung/Joule heatpump. The buffer...
Evening all,
I’m currently in the process of refurbing my house, and have opted to wet UFH for the whole of the downstairs.
The upstairs will be radiators.
The flooring I’ve chosen is 14mm thick engineered wood and I just wanted to know the best way to do things.
At current, the builder was...
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...

And i was wondering if i could get some ideas on how to price the labour. looking around 2 weeks to complete the job with 2 men and a apprentice. any help would...
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...
Hi all. Hope you are well. I need to quote for a job where they want underfloor heating downstairs in the dining kitchen area. The dining room is screed and insulation. Old screed I have taken up and the old is suspended floor with 100mm joists with sleeper walls 350mm apart.
Anyone use a...

Hi,
I have a strange problem in my recently purchased property. I hope someone can shed some light on it.
In a nutshell, when a thermostat causes the underfloor heating pump to run, the boiler does not provide heat unless it happens to be switched on manually or by the boiler timer.
It is...
Hi all,
Looking for some advice. Recently moved into a new house and we've been doing bit and pieces to it, we're now at the point where we're looking at the heating system. There is currently a multi-fuel burner which provides hot water and heat for the radiators, there is also an immersion...
What are the disadvantages of low profile wet UFH boards, in comparison to conventional pipe-in-screed systems (those in which there is at least 50 mm of screed)? Would these disadvantages be as relevant in a small bathroom (wet room) application, for which the total floor area is less than 10 m2?
Hi, I have a Grundfos UP15 42RUC7 circulator which doesn't appear to be working. the impeller moves freely when I spin it manually but when there is power tot he device all I hear is humming but the impeller doesn't turn even though it does not appear to be stuck. Also, oddly I can not find my...
I have a OMNIE designed wet underfloor heating system on three floors. Ground and 2nd floors work well with those two floors having a single manifold and recirculating pump for the various zones.
On the 1st floor the rooms are split over two manifolds each with its own recirculating pump...

HI, we have replaced 3 manifolds (1 upstairs 2 downstairs) with new Warmup units. The installation manual from Warmup states that to fill the system you have to fill each circuit in turn using the fill / drain points on each manifold. However, my plumber said that he always uses the filling loop...
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?
Need some advice and help! (I am not a plumber so will try and give as much info as i can)
I have a room in my house with 2 loops of ufh in it. They are controlled by the same thermostat.
They have separate actuators at the manifold as well.
When the heating comes on one actuator opens fully...
