Condensing boilers

From some points of view, yes.

However, I'm honestly puzzled.

I thought most condensers were multi-part heat exchangers. However I can't see how the number of parts used to manufacture the heat exchanger, nor whether or not it has water on the outside, can have any relevance to cleanliness.

Since the his obviously refers to the previous quote...

So needs less servicing than an older boiler?

I'd agree with that, but simpletons like Drivel use efficiency figures to 'quote' actual gas bill reductions when replacing older boilers.

But there's far more to go wrong in an electronically controlled boiler. To me it would make sense if the electronics were mounted some way away from the boiler so they could be kept at a near constant temperature.

He is still confused. Poor soul.

An annual service of less intensity. Also running more efficiently for longer.

..here is a man who doesn't know, a man who has no clue ..about the things which are known to folks like me and you

..vacant in his head ..no knoweldge, reason, logic, this must be said

..drivel and babble just comes so ..relentless, incoherrent in it flow

..it's time take no notice of this senile babbling fool ..just thank the Lord you are sane, normal and cool

I'm surprised there's that much coming out. Still, I suppose it *is* a weak acid, which must help a bit.
