Folks
Summary - Switching on central heating doesn't start gas boiler, hot water needs to be switched on as well - electrician claims this is the normal way these things are configured. Is he talking through his..?
-------------------------------------------
I'm just getting to the end of a bit of a renovation and while I was doing it I had my hot water system replaced with a pressurised system.
The existing natural gas boiler was retained and the central heating hasn't been pressurised.
The electrician onsite fitted a new control system but when I went to test the system (he'd already left) I discovered that putting the central heating on switched on the central heating pump but didn't fire up the boiler. Switching on the hot water fires up both the boiler and the hot water pump.
I called the electrician and explained the situation and he tells me that this is the way it's supposed to be, if you want the central heating on you have to set the hot water to come on at the same time.
This certainly wasn't the case with the old system and I think he's having me on but he's so adamant about it that he's got me doubting myself. He says he can set it up the way I want i.e. either can be on independently but it will be really complex and require a relay, etc and then started to try to baffle me with electrical terms (I hadn't the heart to tell him I have a degree in Electrical and Electronic Engineering - I wouldn't make any claims to be an electrician but I know enough to know it sounded like crap)
Could anyone offer an unbiased opinion? I don't want to start a fight with what have otherwise been a great team of builders.
thanks
