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 folks,
I have newish gas boiler in 5-bed period red-brick house.
The ENTIRE house has underfloor heating which works pretty well.
However, my gas boiler provides heat for underfloor heating and also heat for hot water. Obviously these are at totally different temperatures.
ALso, there 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 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...

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.
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...

Hi,
I have had an extension built with underfloor heating installed.
The area is open plan and some 64 sqaure metres. Two pipes of 100m each were used - so the manifold has two "ports".
I have a couple of questions if anyone can help please.
1. Is the 200m of pipe enough for the size of the...
Hi there, just after some advice. I have an underfloor system installed and at the time of laying I had a spare loop put in with a view to adding a conservatory. I've now changed my mind and want instead to add in a single radiator. I can see the unbroken loop protruding into the conservatory...
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 seaside apartment in Azerbaijan, currently a bare core & shell, not even internal walls yet, and am intending to put in wet UFH with ceramic tiles on top. Although we will get someone to do this for us, in my experience here it's always best to have a pretty good idea of what needs...
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...
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...
Hello,
I have a Vitodens 100-W B1KA Combi boiler installed in a new build. In the first 4 months of use the boiler has burned on average 500 litres/month. Not sure what I was expecting but that seems high. Any dieas of what I can do to improve it? I've eliminated any ramping by keeping the zone...
Hi, I’m hoping someone can help – I need a bit of advice / help as I'm not sure if the recent cold spell is too much for the UFH in the main living space (it's a barn conversion so 25ft high vaulted area) and I've checked all I can think of. It's 15 degrees despite all looking to be OK to me...
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...

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 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...

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...
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...
