Hello, recently my central heating stopped working and an engineer diagnosed the problem as being that the electrical connection point on the heating pump has partially melted, presumably due to the connection being poor. The pump is inside the boiler body. He recommended replacing the pump and wire that connects to it. He's given me a quote to do the repair that seems rather on the high side, and I was wondering does anyone here have an idea of whether it's reasonable?
The labour costs quote is £180-250+VAT (~2-3 hours' worth) for changing the pump, plus £180+VAT (a bit over 2 hours) for draining and refilling the whole central heating system (which he says is necessary because on my make of boiler, the boiler isolator valves are unreliable). This is quite a lot more than other people I know have been charged for a pump replacement, though I know it can depend on the boiler. I've read that draining the system can be done in ~20 mins, but I've not been able to find out how long it should take to refill it. (The engineer estimated the system volume to be ~50l.) Do you have insights into any of this?
Also, should it be a concern that the connection got hot enough to melt in the first place, or would replacing the parts really be likely to correct any problem there?
Thanks very much for any help.
