Hi,
I'm having troubles with my old Saunier Duval (I know, I know...)
combi boiler:


Here are my questions:
1) what is the problem?

What's the boiler

2) can I fix it myself (I've pretty near no experience) ?

Difficult to say

3) can you recommend a heating engineer in East London / London ?

One of my customers specialises in Saunier Duval repairs

Bill Jenkins

He's in E4

He also knows what he's doing.


Thanks folks !

I have the same symptoms.
I think maybe it's a flow divert valve not working, and when the hot
water does work (CH on), it is just referred heat from the CH.
Gas guy said something about an additive in the supply gas causing
diaphragms to deteriorate or stick.

Could this be true?

If it's an additive in the gas supply, that gas guy told you wrong. The
diverter valve (or hot water flow sensor/diaphram is nothing to do with the
gas supply so it matters not what additives they put in the gas. If he was
talking about additives in the CH system - that's a different matter, and he
*could* be right. I've had a diaphram go in my old combi in the 9 years I
had it. AFAIK it had no inhibitor added - certainly the colour of drained
water from the system shows no sign of inhibitor (I bled the rads fairly
early on in the system's life).

Your point makes sense. This is a 2 year old Ariston boiler. No
inhibitor either.

The Ariston boiler 'sings' at the flue outlet, quiet but high
pitched, which'd put me off buying another one.
