I called out a corgi heating engineer because a motorised valve for my unvented system blew a fuse (it was sited under the bath) - the engineer then condemned the boiler for thee reasons
Floor standing boiler sitting on combustible material (can be fixed)
No terminal guard fitted (within 2m of ground) (can be fixed)
Flue not 300mm from doorway/internal corner (flue is on outside wall within 300mm of a garage back door)
He also said electric components under the bath were a hazard
He recommended replacing with a combination boiler and installing this in the upstairs airing cupboard (because it was 'easier' - no extra components to install)
Current boiler is potterton Kingfisher (looks old) - 3 bed semi, 7 rads, 1 bath, electric shower - I don't have the heat loss calculations) it is installed under the stairs (presumably a health risk?)
My questions:
What are the regulations on siting flues? can you use an extension kit to comply with the regulations? Do condensing boilers overcome any flue regulations? (less exhaust fumes/heat)
Do Corgi regs cover siting of electrical components like motorised valves?
I have had several corgi engineers round all giving conflicting advice on combination boilers vs conventional - some say 24kw is enough others say 28kw and minimum flow rate 0of 10-11 litres/min - I have tested mains at c. 20 litres/min
Depending on the regs do I have any choice (only place to install is in airing cupboard if under stairs is a no no)
Is it really easier to replace with combination boiler?
Engineer also said he would flush (not powerflush) the system with the new boiler installed - is this sound advice and in line with manufacturer benchmarks?
