I have old gravity fed central heating system and the hot water pressure is very low can anyone help as to what could be the problem :?
The heating system consists of a tank in attic,a tank above the the hot water cylinder.[/b]

Is this a problem that has just started, or has it always been that way?

If it's just begun it could be a partial airlock or a restriction in the pipework from the cylinder to the hot taps.

If it's always been like that, you could get a better flow by raising the level of the cold water tank above the cylinder that feeds it.
