Presently have a conventional Trianco 28/32 Redfyre oil boiler with 5" non balanced flue, which is surrounded by a stainless steel outer wall. It runs approx 2m vertical from boiler into loft space then 45deg elbow then 2m at an angle then 45deg elbow, then finally 1.5m vertical out through the roof into the open air.
I'm told new boilers are condensing type.
Do I really need to change the old flue, it alooks in good working order? If so why?
