Just a bit of info that may save someone time and trouble. If you get the dreaded lock out situation on the Suprima HE check for a frozen condensate pipe outside the house. This will be quite common at these temperatures. Going to get some lagging now it is cleared again. Might save you call out fees even if insured as frozen pipes often not covered by policies

New PCB cleared previous problem (original post) by the way

Which will be as a result of incorrect installation by a monkey with a certificate!

They need to teach these fitters to read as part of the gas safe process!

Thanks Marks - what is correct instruction on this if you have it please or link to what should have been done? Much appreciated if you have something.

Potterton have some decent info in the installation manual from memory.

The basics are that if its external it needs to be in 32mm pipe (waste pipe), idealy insulated and have a fall of 50mm in 1m.

Have a look at appendix B of this:

I'm glad mine is indoors .. well, in a sort of half-indoor cupboard (gets down to 5.5C in this weather but no lower).. although there is a nice 'uphill' section in the pipe thanks to my plumber who was apparently unfamiliar with the concept of gravity..

My boiler is in what used to my airing cupboard and doesn't have an external wall, so my boiler condensates into a saniflow type tank complete with pump that pumps it up trough my roof into the gutter. This was at my suggestion verses how he wanted to plumb the bottom feed boiler into where the original boiler was sited.

Thanks for that - my pipe is 4m external - now reduced to about 1.5m. It was only 25mm in diameter which might have been ok under old regs but certainly is not now.

Apparently even the 32mm has been freezing at other houses.

Only acceptable if you have a combined foul and surface water drain..

I can't complain too much - he fitted it in October and still hasn't sent me the bill! (He was my next door neighbour - now moved further south) ... maybe he'll forget

Mine is in what is essentially the gas meter/electric meter/fuse box cupboard which has an inspection hatch into the downstairs bathroom (it's a weird sort of half room thing).  It's on an outside wall, so the over-pressure vent is piped outside, but the condensate drain is piped down into the main soil pipe since it's not more than 4' away, which was handy.

Though I was a bit worried that the cupboard might drop below freezing (it's not very well insulated.. the whole house isn't!), fortunately it's lowest temp is above freezing (and just below the frost protection temp on the boiler)..

The regs state that insulation is required in exposed locations

According to a mate's Dad who was a plumber all his life nowhere in the borough has seperate drains, tis but another southern frippery we manage without oop north.

Ow dear, another plumber talking out his ass.

Its been a requirement of the regs for 20+ years so all recent build will have them.

As he's been dead for most of the last 20 years I'd imagine he was spot on at the time.

we have separate foul and rainwater drains - can condensate go to either then?

No, its slightly acid so can NOT go into the surface water drains
