Increasing the water pressure in bungalow

Hi,
There is the copper hot water storage tank in the house (bungalow). For the bath, there are regular bath taps.

For shower (in the bath), there is an electric shower.

In winter, the water in the hot water storage tank will be always hot. It is wasting the electricity to use electric shower, when there is tank full of the hot water.
I would like change those bath taps with the bath shower mixer

I will keep the electric shower too for the summer time, when central heating is turned off.

But there is a problem with a water pressure. The height difference between shower head on the wall and water tank on the attic will be only about 1,5 metre what is 0,15 bar. It is very low.

Can I connect mainn water supply to the house plumbing throught water presure regulator, wich will be set for 0,8 bar. Because it will become unvented system, I will install at the hot water storage tank pressure relief valve setted fore 1,3bar, to release the pressure if the water in the tank will warm up.

Will this work? Can I increase the watter pressure from 0,15 bar to 0,8 bar this way? I have no option to move water tank on the attic higher. :-(.
The copper hot water storage tank is designed for 20 PSI what is 1,3 bar.

Thank for help.

No ! No ! No ! No ! No !
What you plan on doing is lethal
You can't just pressurise a standard cylinder the word " BANG" comes to mind

I would like to avoid the word "BANG".
OK, so what else I can do? Replace the standard cylinder by the pressurised cylinder by the plumber? I think it must to be made by the plumber.

Fit a pump to pump the hot and cold to the rest of the house , bear in mind that the pump will activate when you flush toilets , can be annoying if people are in bed and someone uses the toilet , some people fit a timer on the pump so that it is powered off during bed time , another thing to watch out for if fitting a pump is you will use your hot water quicker so a larger cylinder would be advised and a surrey flange should be used at the cylinder to prevent your pump drawing in air when used

You need booster pump,
something like Triton T40i or similar

Actually yes that would work , I thought the OP wanted better pressure all over the house reading back on his post it seems he just wants it at his bath / shower mixer

Depending on your hot / cold pipe layouts, if your house has all the pipework in the hot-press and there is enough space then a brass bodied, twin impellar Stuart Turner pump would be my recommendation.

As you have your water tank in the attic you would use a positive head pump which looks like this. Plumbed in correctly it will provide plenty of pressure in your bathroom for showers.
