Well went over today and he seemed a decent chap. I have to say that if he did tile his floor himself I would take my hat off to him. It's probably the best tiled floor I've ever seen someone else do, including all the professional tilers work I've seen.
He had a gas fitter out recently but he fell out with him as the guy was telling him that a motorised CH zone valve letting some water by is normal. Rads are heating up a bit when HW is on (it's a normal condensing boiler on an S-Plan system with unvented hot water cylinder). The guy is an engineer and wasn't buying it.
Quick question for all, he also says that when the CH heats up from cold, there is a whistling noise that comes from the airing cupboard. Only happens when CH is switched on, if HW is on instead then nothing happens. There is an bottle air vent in the airing cupboard which was closed completely so I opened it up as it's an automatic air vent after all. Will see if that does it but does anyone else have any ideas?
Never come across it before.
His work in the en-suite looks grand to be honest, so I'm happy to take it on but will charge a bit of a premium for it I think.
