I have a Glow Worm 45 back boiler gas central heating system which wa
installed in 1991.It is only giving me hot radiators but no hot runnin water for a bath etc only cold water is coming through.I also have th hot water cylinder in the loft.I'm led to believe the diverter valv must be the problem as I have had very occasional times when hot wate will actually flow through the bath taps.Do you know where the diverte valve will be,how to check whether it's knackered or faulty & is i diyable to replace ?
many thank
