Right - first things first - I'm a complete ignorant when it comes to plumbing issues so please treat me as a simpleton when explaining anything to me!

I've read through MANY posts about how rubbish these Suprima boilers are, so don't worry I know how bad they are.

My problems is slightly different from others.

We have central heating, but no hot water.

When the timer/control is set to permanent or just switched on for the central heating, the boiler switches on and fires up.

When you do the same for the water however - nothing!! Though the red light on the timer is on. It just stays on red on the boiler.

BG have been round and he reckoned "100%" that it was the Myson Power Extra switch/valve.

Now before I commit to paying for something that might not fix it, be interested in some expert views - reckons it will cost £125 all in to fix - sounds reasonable to me.

Any other views on what it could be or if price is OK?

Thanks guys

Slim chance it may be the cylinder stat or even slimmer the programmer. More than likely the motorised valve.

Firstly, Suprimas are excellent boilers

Secondly, if BG are 100% why worry?

I assume you have 2 2 port valves? In which case I would fully agree with the BG diagnosis.
