Shower connected to taps question

[OriginalHugsy]

I have moved to a property where the bath taps are mixer taps with a connected shower hose.
The problem is that if you use the shower bit, it's always way too hot even if you have the cold tap on higher force than the hot tap.
I am really bad with plumbing and boiler terms and knowledge but we have a boiler that heats the water up and stores it until it's used ( I think )

is there a hot water cylinder? What colour is it?

If a boiler, how big is it (this is not a joke) and can you see a make and model? Is it a gas boiler?

Is there a cold water tank in the loft, or on top of the hot water cylinder?

If you put your thumb on the bathroom hot tap, can you stop the flow? What about the cold tap? Is the pressure foe each any different at the sink?

Hi thank you for replying. I will try to answer what I can
The water tank is a green sort of colour and it's just one big thing.
We live in a flat so can't have Anything in a loft.


The boiler is under the kitchen sink and the make is Potterton I think, can't see model number

The cold water pressure is definitely harder in both sink and bath but hot water too hot to try and stop it.

Does that help any??
Thanks for your time again

If you have a green cylinder, then it will be fed from a cold water tank. Sometimes this will be on top of the hot water cylinder itself, you will see there is a sort of waist where it is attached, about a quarter down from the top, and if you feel on top there is a removable lid, and you will hear water running after you run the hot tap. If not, it might be on a high shelf in the airing cupboard, or, in an older building, there might be a shared tank in or on the roof.

Does your flat have gas? Does it have radiators or storage heaters? How old is it?

The cylinder may have an electric immersion heater or two. If so, there will be a round plastic or metal cap about 80mm diameter in the top or side of the cylinder, with a cable coming out of it probably going to a switch on the wall. Switch this off and see if the hot water gets less scalding later in the day, and then runs out.

Photos of the cylinder, showing the pipes and cables round it, and of the thing under the sink, will help.

Look at your electricity meter. How much have you been using, averaged per day?
