Hello,
Is it worth having a balanced flue? My boiler is in the kitchen next to the door, so I cannot have a low level flue because it would be within 600mm of the door. There is a chimney behind the boiler but the grant "red" balanced flexi flue kit costs £600 plus vat. OTOH their "orange" conventional flue kit costs just over £200: a third of the cost. Is there any reason I have to have a balanced flue? Could I stick with a conventional flue and save the cost?
There's already a 100mm steel flue in the chimney but the old boiler was non-condensing. Am I right that this would have to be replaced because the acidic condensate might attack the metal? If I went with a non-condensing boiler (see other post), could I get away with using the old flue?
Thanks, Stephen.
