which regions of the UK would this be for then? And will water costs be included?

maybe the hinge is flimsy enough to bend until the rear buffers contact, upon first use...

yep.

?

So, what temperature *are* all these radiators at then?

which is inspected and agreed by BCO.

Never seen a rest bend used in NI.

If it 22VAC off load and you're only seeing 5VDC out of the bridge, there's a short somewhere IMHO. I'd be removing the supply from each of the op-amps and from the two cards, to try and pinpoint it.

something's certainly pulling it down. Maybe try cutting the odd track to narrow it down?

if you vitually ignore the wheely washing lines and the overpriced windows can you then have a coffee and go home again?

where in the world are you?

It's not.

looks great. Is that Howden's Clerkenwell?

So that's the screed drying out nicely now. After the first week of instructed "no heat" I ran the Willis on a 15min every hour cycle for a fortnight. Then on a whim and cost be damned, I put it on continuous for a couple of days. Result is that I'm pleased to see that the heat calculations are confirmed and the house's heat requirements are indeed low. 3kW heater on continuous for 52hrs total, mean ambient temp of about 3c over the duration, raised the slab return temp from 11 to 17c and still rising- and brought room temp from 10c to 15c

there's a capillary coiled up there and i'd presume it's into the flow above the pump

cold water has to leave the return to let the manifold loops sup the hot stuff tho?

Rebuilding them generally isn't hard as long as the bearings haven't partially seized and chewed up the shaft or housing, but if you don't have the tools or skill-set then I'd go with @PeterW's view.

it's a Papst external-rotor fan. Generally there's a removeable cap in the middle of the mounting bit, and a circlip under that holds the fan and shaft in place. the fan and rotor will then pull off and expose the coils and bearings. /similar motors are used in scientific kit like incubators, that I work on daily.

Did you try Appliances Direct Dave? I know that Ian was unimpressed be I got a cracker island hood at sensible money and they were happy to deliver to BT reasonably.

^yep.

unless they're pre-drilled like these: http://www.ridgetiles.com/

doesn't the dry ridge roll have a self-adhesive underside?

Accreditation and proof of competency are separate things tho. Download the blank EIC and have a look at it https://electrical.theiet.org/bs-7671/model-forms/ You'll need all the right test gear and also be happy to sign-off the relevant sections.

*from* the treatment plant surely?

AFAICT you don't need to prove competency by providing training or membership certs, but you will have to be able to offer a completed EIC. I don't think the BCOs have a facility for inspect and test?
