This is another installation example of a situation where it is requested that we fit a new high efficiency boiler to an old chimney stack.
We are in the town of Sevenoaks, Kent (UK) where there is a 35 year old floor standing Potterton boiler in the breakfast room, using a flue passing inside a brick chimney.
Old Potterton boiler - casing removed
We specified a Viessmann Compact WB1B 26Kw unit, with a sealed system chimney liner. This allowed us to install a room-sealed boiler using the stack for exhaust and fresh air inlet.
Getting ready to re-line the chimney
Old boiler flue liner removed
New Viessmann roof terminal being installed, new mortar rendering
We removed the old boiler, rationalised the pipework. The customer then had the chimney swept, we installed a scaffold tower outside and fitted the Viessmann flue lining and termination kit.
Halfway through the job - old flue hole to be bricked up
Job done, a 30% improvement in boiler efficiency – and the house was unchanged. Every other ‘gas specialist’ the customer had round said it couldn’t be done. They should get out more!
Finished - only brown paint required
