Can hot water cylinders lost pressure?

Cold water pressure is fine, but hot water out of all taps is slow as, never used to be.

Is there an overflow pipe out the top of the roof or out through a side wall?

Out the top.
Had plumber look at that nearly a year ago as it was overflowing

In our past 'older house' the pipes had simply gotten clogged. Like clogged arteries after a while.

Replaced with new piping - water as fast as! But we also switched to gas at the same time so . ?

At the bottom of the cylinder should be a pressure reducing valve. Sometimes all that is needed is to screw the screw underneath it clockwise until water come out of the overflow pipe, then wind back half a turn.
If that doesn't fix it you'll probably need a plumber.

Thanks trade4us, I will have a look tomorrow when it's light. I do notice that water has leaked as the floor is wet and free mushrooms all round.

Spare parts are usually available for the reducing valve. The rubber diaphragm is only about $15. After many years that can leak. But it's really a job for a plumber or experienced person to take the valve off and have a look inside. The plumber might say it's cheaper to put in a new valve.

I guess it's getting old, just like me and things start crapping out
