Hi,
We've a Baxi 105HE Instant and it's been losing pressure (slowly) for a while, I found that it was dripping slightly from the flexi hose on the bottom, so tightened this all up and assumed the pressure drop had been down to this.
But, on Sunday, it started to pour water out of it while the heating was on, I turned it all off, and popped the cover off just to see where the water was coming from.
It was dripping from the top right of the boiler, where two pipes connect, the secondary heat exchanger I believe? And also, from the pipe that ends in a rectangular end into the left hand side of the combustion chamber.
So, I'm assuming dead secondary heat exchanger and the water coming from the side of the combustion changer was a side effect of the exchanger dumping water into the system?
Not touching it myself, got a plumber coming, but just thought I'd check here to see if my thoughts were correct.
If they are, I assume symptoms like this are going to be down to the Secondary HE having failed, and not just the o-rings? So I'm sadly looking at a reasonable bill.
