WOW chk

Are you sure Ermi, there in the common market like us, that's a lot different than £50,

£35 for this 18L one, about time you lads started filling your profile and tells us where you live then
we can perhaps understand why the difference in prices.

Ermi,

Why would he want to do that when he can get a vessel that will last longer for less than £50.00 twas you yourself who said they go flat like larger, and to get to the new internal vessel fitted would have to remove the boiler case, whoops, no can do. Leave the old tosh where it is and fit an external one. If you had a Ford van would you always insist on fitting FORD OEM parts on it.

Sorry. I would never advocate installing a valliant one they are pure pish. I was saying that they are ludicrously expensive ?? My tread is a little pish, distracted with electronics problem on network. Testing but takes ages. Sick!!

Come on Mr Croppie - if a boiler is located in a loft space - what are the
requirements to keep us all safe. I understand from friends at BG in low places that the
loft space MUST be borded (cant spell) and be a 'safe area' before any engineer can go up
- please keep us safe Jon

CHK ... If my memory serves me right there should be good lighting and access plus floored out. The loft ladder also requires a hand rail. 🙂
