No hot water - Gledhill Boilermate OV A Class

[Stewartk]

I have a Gledhill Boilermate OV a Class. Boiler switched off, gas board came out to check everything boiler started again. Since then Central heating is working fine but the hot water is not consistent. I get a small amount of water, enough for a very quick shower, not enough for a bath. If you then wait a while the water does heat up again but not does not last long. Gas board said it is something to do with the 'Switch' system.
