Gas Combi Boiler

[lichfield08]

I have a Calydra C & M combi boiler. It seems to have a mind of it's own ! When I put the heat on I am more likely to get hot water than heat or maybe neither. I have figered out that this is not a good boiler, but other than spend £1500 on a new boiler, what do I do?

Sadly, that's a bit vague, Lich. There are so many possibilities.
Perhaps the valve that switches between HW and CH
Printed circuit Board
Even a cheap little thermistor somewhere.

A heating engineer would have to be there to try a few things out. He would also give you an opinion as to whether it's worth repairing.

Yup, if you ain't an expert you usually have to pay one.

Thank You to The Builder, Jomifl wasn't very helpful though. Does he have a degree in the bleeding obvious ?

Lacking any useful clues in your post I made the most helpful comment that I could, however if you could supply more information then I would be quite happy to help, though as TB is on the case my help would probably be redundant;-)
