Simply Build It

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.
