Scrufflepeck said:Move it - but a Corgi registered engineer almost certainly wont certify it as OK unless you offer him a bribe. Like the man said, if it aint condensing it aint compliant. B&Q do a reasonably priced Ravenheat combi which is on special offer at the moment. You could get this baby installed and commissioned for £1200 (plus VAT) - a snip!
Hope this helps!

Don't buy a ravenheat whatever you do mate.
