Internal flue

Something I’m grateful to the planners for is the internal flue from the stove. If I’d had an option, without thinking, I’d probably have placed it outside running up the wall externally and in doing so lost an awful lot of heat. Instead, as required by the planners (my plans didn’t show where the flue ran and I was ‘informed’ that a reapplication for an external flue was likely to be rejected) it runs internally and keeps the bedroom (more of a store room at the moment) that it passes through lovely and warm with heat we’d otherwise have lost.
