Shower Power

Morning,

Bought a house in May and since then the shower has been a bit strange.

It works fine, nice and hot early in the morning (before 0800) but if you try and use it after that not only does the temperature fluctuate but so does the pressure.

No one is using water at that time and neither are the machines.

Boiler is behind the shower in the airing cupboard if that matters.

Any thoughts on why the temperature and pressure fluctuates, but only after a certain time?

If it was a thermostatic shower, it would stabilize the temperature regardless of water pressure.

What sort of boiler and shower you have?

Combi boiler?
Is it any time after 8:00am or say 8-9?
What kind of house is it, new build on an estate?

Could be the local peak draw is highest at that time, reduced flow knocking out the boiler at that time.
