Should I repair or replace my old boiler?
22 Dec : Updated 24 Dec ● 1 min readReplace. A repair can sometimes be as expensive as a brand new boiler. And you could easily have more problems with a repaired boiler further down the line. A boiler replacement is usually more efficient and more reliable. Your new boiler will be covered by warranty too, so if it breaks, the manufacturer will repair it with no extra charge.
