Is lighting fire in redundant back boiler safe?
I've got an old back boiler solid fuel but it is redundant now for many years but I still light the fire is this safe done it for 7 or more years.
Advice from 3 local tradespeople
No the back boiler needs removing and all the chamber and chimney flues need checking for leaks by using a smoke bomb pellet and possibly fitting a new style flue liner down the chimney
Should have flue checked really and a carbon monoxide detector close by
The boiler should have been drained and left open vented. Some traders will drill holes in the back boiler which we do not advise. We always recommend a Hetas engineers to check before use.
