Hmm, How about an upgrade to coach screws? I guess they'd have the advantage of the head not being countersunk too, and easier to drive with a socket set. A combo like this maybe? EDIT: seems links may not be working. The links are to: 8mm diameter x 70mm hex head coach screws 10mm diameter...

Hi all, Sorry if this is in the wrong forum section - let me know if I should post elsewhere! Currently fitting a new IKEA kitchen, they come with the metal rails, which you fix to the wall and "hang" the cabinets onto...

Great. So here's the plan for connecting all this up. The real wires you see in the Nest Heat Link are existing, but I've drawn the planned connections over the top. Anyone's thoughts would be greatly appreciated! OMNIE Wiring Image by greenstarthree01 posted 27 Mar 2020 at 10:04 AM

Great, I think I'm understanding this now, but am still working on drawing out a diagram beforehand, and will post that asap. What's the recommended way of powering all this, if adhering to EricMark's advice of having 1 FCU switch for the lot? The boiler's manual advises to power it directly...

Hoping to provide some clarification and as @ericmark suggests drawing some diagrams. Here's the existing setup. CURRENT CONNECTIONS by greenstarthree01 posted 26 Mar 2020 at 5:08 PM Working on the proposed new setup including UFH now. EDIT Also adding an example wiring diagram from Omnie...

Excellent, thank you. So this just leaves one question regarding the Heat Link's connection to the Omnie Wiring centre: All of Omnie's wiring diagrams presume you're using their own controls (of course), and have this kind of wiring at the zone terminals: OMNIE ZONE 2 by greenstarthree01 posted...

Hi, it's the DS-EWC1 wiring centre thanks EDIT Just opened it up again and realised that it does have what's labelled as "Volt Free Relay- Boiler" as well as the mains live output that goes to the pump. The wiring diagram I got with the Omnie is not particularly specific (it shows the boiler...

@ericmark , thanks for this - lots of good info there! Ok... So to confirm, I could swap the two wires over between Heat Link and boiler to get them matching what seems to be "standard" installation, without risk of frying anything? One thing - when you say they're 'volt free' connections, why...

A quick follow up: blog post (which in turn references an older DIYNot thread) suggesting the wires should be connected the opposite way to mine: https://www.linuxtutorial.co.uk/install-nest-heat-link-thermostat-with-a-baxi-duo-tec-combi-boiler/ Also, thinking about this, in my situation...
