| Thanks Pete. Have already had a look at the Megaflo site but last night found a DIY forum where someone with a similar problem had posted a query - and wished I hadn't! The poor sod had inadvertently pushed the red button to start WW3! Eighteen pages (I kid you not) this thread went to, the first two staying on the point but the rest an increasingly bitter war of words between a small number of heating engineers. When it comes to bitching the DSC are definitely junior leaue! Never did find out if the guy got his system fixed as gave up on page seven feeling severly depressed. Won't bother posting a request for help on there, then! However, the iphe website proved much more fruitful and have located a plumber with knowledge of unvented systems only a few miles away from me who is coming round Tuesday to (hopefully) get me sorted.
