Thought you'd be interested in an update....
B Gas quote £3,999, that's after their 10% promo discount (yeah!).
This includes:-
- £1200 worcester boiler (only 24KW mind, not the 30 KW I wanted - see below)
- £1000 scaffolding to get to the Flue (second storey flat)
- the other £2k is installation; VAT; upgrading the size of the gas pipe from the garage basement from 22mm, to 38mm for a 3 m run, and upgrading the pipe supply from under the sink in the flat from 15mm, to 22mm (he said that would give enough pressure for a 24KW boiler, not a 30 KW); flush; magnetic trap filter, and a few other bits (no new controls, just keep the existing wired thermostat, and existing TRV's). Great
Only 10 flats in the block, and several have replaced their boilers, but no one else has had their gas supply pipe upgraded (all meters and supply pipes visible in the garage basement).
Managed to get a Genuine new Gloworm fan and Thermo-couple from the tinterweb, and getting engineer to fit - should be circa £300 fitted. I cant justify £4000 on a new BG boiler and risk the tenant bashing the cabinet, or cleaning it with a scotchbrite pad - that would really hack me off.
Thanks for the suggestions and comments - a great place to bounce problems off - cheers
