Soz, I am laughing at the idea that he has taken money from me! Not a chance!
I guess he had another customer lined up as he thought the job would be simples and it turned out not to be. So after phoning up his mate about the wiring of the motorised valve and deciding that despite having done this correctly, it was all beyond him, he told me he'd get a sparky in. which to be fair he has arranged quite quickly, considering how "rammed" all the plumberers and heating engineers always are at this time of year. He then beggared off to do the other job he had lined up.
The pump should be OK with only its power side wired in, according to the installation instructions etc, (see previous posts and links) the other little plug is simply an option on some systems, but not ours.
I didn't say it is HW OR CH but never both, here is what I said "What he had trouble "getting" is that the old boiler only ever worked as "HW only" or "HW and CH", it could never do "CH only"."
This was quite normal for a long time and TBH I have only ever lived in one house that allowed you to have CH only on. And that system was fitted in a house that belonged to a gas engineer.
So this house, my previous house, my Dad's house and our previous house to that all had either HW or HW and CH.
I have spent a lot of time this arvo rewiring a socket that suddenly decided to be intermittently working. In the process I had to source some new earth wiring as the body and face plate of the plug are all metal. This was fun as I don't have it in stock. I pnched a bit from the long crossbonding wire I will be attaching to a sink when I plumb it in, it is miles long so could afford to lose a bit. But of course it had too many strands in so I had to flip about making sure it had the right cross section, i.e.e only two strands, to replace the original, plus the earth coloured insualtion sleeve. Such a pain working stretched out over the washing machine, especially as it isn't a spur but part of the ring, so every connection is to two wires and they never seem to be long enough. anyway, got to the bottom of it, put it all back together and the smoke stayed in the wires when I tested it.
W wanted my help deciding on menus and wines to go with over the Xmas week when we'll be away in the Dales. So that took a bit of fiddling around with spreadsheets (where I keep track of the wine and their prices) to make sure we only take the very best ones with us.
So CH wiring fiddling around with has now been put off until tomoz. Normally Sunday is the one day we do very little. Plus W has been in a moody all day, in a lot of pain with her guts, poor thing.
Enjoy the evening folks!
