when i top up the pessure to 1.0bar and dont use boiler the pressure will remain ther.go,s back to 1.0bar when using hot water,however when i put heating on pressure go,s to 3.0bar but then after an hour or so pressure drops reading zero.only happens when using heating.some came round and said need new expansion vessel and new calorifier.would this be correct
my ideal classic ff280(fanned balanced gas flue boiler) will only ignite/fire up, when the front cover is gently thumped/tapped near the pilot viewing window. Once fired up it works fine until it turns itself off and won't reignite untill it is tapped in the same place again. Any ideas please.
