My 15 year old boiler makes all the right noises, lights up on cue and produces luke warm water. All thermostats (boiler, water tank and room) are up to maximum but the hot water and the radiators don't get hot. Literally, just luke warm.
I had a new pump fitted a few weeks ago, also a new three way valve last year.
Any help would be greatly appreciated.
