Thank you. So .. The UFH flow must be changed to be upstream of the 2-port CH valve, to permit independent operation. Can the UFH return be left as-is (commoned into the CH return) so that will be upstream of the HW cylinder return?

Is that to prevent reverse flow to the cylinder and rads?

We have a new underfloor heating system laid in an extension. This requires flow and return water from the boiler. The existing system boiler provides hot water (indirectly via a cylinder upstairs) and the existing radiator heating. There are 2x 2-port valves, I think this is a classic "S...

Ooooh matron!

Bump .. Anyone?

We have a Hive thermostat in the hallway, controlling CH + HW for the house. We have the Hive hub (connected to an Ethernet switch and from there to our mesh wifi) + the app on the phone, working well. Our extension will have a new water underfloor heating "zone" controlled with a manifold (see...

Just to confirm, the self-tapping screw did fit nicely in the side of the cable strain relief. Job done, using 3183TQ heat-resistant cable. Our local CEF branch offers a "cut cable to length" service, so it was less than £4.

This PDF is identical to the small paper leaflet that came with the unit. It shows a the different method of mounting. Whereas digging around online I found this method which seems to be exactly what I would need to do...

We had a new Joule hot water cylinder fitted in November '24 (along with a new boiler, and a change to be an unvented, pressurised system). The immersion heater (pictured) was fitted to the cylinder, but not wired up despite us having the double-pole switch nearby (from the old one). Not sure...

Checked last night - and the rad is now getting warm - similar to the other ones in the house, after getting the lockshield open approx 1 turn. I think the whole system needs a powerflush and a magnaclean. The boiler is a Potterton, quite old now but still working. There's no kettling so that...

Also our daughter's place is built in 1995, smallish boiler for the size of the house, and NO MagnaClean or similar. Open vented system, likely to be full of old crap as well. Even if they don't change the boiler soon, I think they should get a MagnaClean fitted (not by me !!)

Ouch. A good experiment for us to try. I read somewhere that they have fine internal holes. I wonder if it's got clogged up during or after the installation. The installation instructions for similar models do not suggest there is any flow direction that needs to be honoured. However they are...

Thanks. Rad is Ximax Champion Duplex Vertical Designer Radiator, White (W)410mm (H)1800mm. Weird that the Danfoss PDF I linked to shows an anticlockwise motion, diagram bottom of page 2. It's unclear which action it relates to.

See pics. This is in our daughter's house so the info I have is not complete. The previous rad was replaced during their kitchen refurb., approx 2 years ago The new vertical rad was supposed to be better than what was there before, but it isn't (currently) and has never worked properly. The...
