After balancing the flows, one of these blighters has started to drip very slowly from under the red cap. It feels loose to turn, so I suspect the seal around the spindle is to blame. It won't be 'worn' as such, as they don't get fiddled with for years, but this tiny adjustment was seemingly...
Lawdie.
With the help of a temperature scanner - an ex-Covid item - set to 'surface', we worked out that no less than 5 zones out of 9 were controlled by the wrong actuator heads. Heads now on correct valves, and all is working fine.

(Can thoroughly recommend an IR temp scanner -...
Thanks.
I wonder if that is all that happened - it fired up that zone from cold, so by the time the air temp had reached the wall 'stat's setting and turned it off, the floor mass was already hot and just continued to chuck out the warmth until it was waaaay too high?
I can't think of...
There is a normal programmer to set the times, but I've set that to 'on' 24hrs. I've suggested she considers the system to have a ~3-hour lag, so to turn her living space up to the required 'evening' temp at around 3pm, so it should be cosy for sitting down from 6pm onwards, and then to turn it...
Thanks Shaun
(Sorry - the yellow circles are a red herring for this Q - that was for a different question when I wanted to know if they could be checked for air!)
Rats, so there's no timed valve/pump anti-seize? It's plumber-time, then.
It's so weird, because the stats clearly otherwise...
Hi.
This UFH system is in my mil's bungalow purchased earlier this year.
It has 9 zones, is run from a WB 37CDi combi, and uses Wavin actuators with a wall stat in each zoned room. It all appears to work just as it should.
A few weeks back, tho', one of the two bedrooms warmed up excessively...
That's a good pic, EG 93!
When you look at it, you'll notice that the 'outlet' pipe on the right is slightly above - or nigh-on level - with that leaking joint. That means that the whole 'U' part is always full of water, so if the O-ring there isn't perfect, it will seep.
Best first step is to...
Thanks everyone.
I don't suspect a current leak, but was sometimes aware of the smell during the installation phase.
Looks as tho' it can be DIYed, but it should have Building Control oversight and sign-off afterwards, just like with many normal building jobs (structural, etc).
Thanks.
Ok, I think I found the answer. Yes, it can be DIYed, but should have Building Control certification afterwards.
Anyone know how to check whether this has been done - will it be part of the online planning portal, or does a request need to be made to Build Control?
Hi. Asking for a relative whose neighbour seemingly DIYed an oil tank replacement. She was aware of 'oil' smells at regular times in the weeks following this, although that has since died down.
Is there a way of checking whether the installation was registered, a bit like boiler installs?
Thanks.
Hi Kiloran.
One of the easiest to use Programmable Thermostats I've seen is the Hive. It has a single knob in the middle that you turn up or down to adjust (override) the set temp; the display lights up and shows the 'actual' room temp and the 'target' temp. Even if she ignores the display...
Yup! In its time it's had a main and secondary exchanger, RH hydrobloc, pump, PCB, and lawd knows what else, mostly - thankfully - covered by extended warranties.
It's a beaut :cool:
