hot water pressure is low from mains shower only, the shower pipe work is connected to the emertion heater from a t-piece junction with one pipe going to the other taps (kitchen sink/washing machine/bath and bathroom sink taps) and the other pipe going to the shower, cold water pressure is fine for all taps and comes out of the shower fine.
what could be causing the low hot water pressure to the shower?

edit:- the cold water comes from a pipe from the ceiling (sorry unseless when it comes to plumbing!) the it t's offf one to the storage water heater the other to supply the cold water to the rest of the flat, as its coming down to the main pipe to supply the rest of the flat theres another t junction, one to the main feed for the flat the other to the shower. The cold water pressure is fine to the shower, its just the hot!!

Furred up pipes,you need a scale master fitted,it gets rid of lime scaleover a period of time.

Basically spread out over all these answers is the right one! firstly, your mains pressure is over 4 bar and your hot water pressure is calculated by measuring the distance between your hot water cylinder and your shower head (vertically of course) it is 0.1 bar for every 1 meter (this is called head pressure) anyway, that is all technical and you really dont need to work it out. You will need a shower pump in order to get a good shower. A 1.5bar pump should be sufficient and can be brought at any bathroom shop, b&q etc. But what the other answers fail to mention is that you must make sure that your hot water cylinder is big enough. If the tank is too small then the pump will draw the water out too quickly and you will be showering cold and be left without hot water until it heats up again. You can measure the cylinder with a tape measure if its not written on it. The cylinder should be at least 45" tall, if it isnt then the chances are you will need a new cylinder to cope with a shower pump. Failing this an electric shower can be fitted as they only require a cold mains feed pipe. Hope this helps.

Usually you find that any water pressure from an emertion heater is less than from mains fed cold water to even these up a bit you should try running a seperate cold water supply to the shower head from the same cold water tank that feeds the emertion tank then you should get an equal amount of water cold and hot. the only other thing i could suggest would be to fit a water pump in the system to give equal hot and cold pressure. Hope this is useful

Your cold comes from the mains.
Your hot comes from the copper cylinder fitted with an immersion heater.
This scenario is doomed from the start, as you are bound to have unequal pressures.
The pressure of your mains is 1-3 bars (15 - 45psi)
The pressure of your hot is less than 1/4 bar, (1 bar is a tank mounted 33 feet in the air)
SOLUTION:- Re-plumb cold to shower from attic tank, fit an automatic pump with dual ends so that you have equal pressures.
I would suggest having this printed so that you know what you are doing.

Possibly there is an obstruction in the pipe, or the valve isn't opening all the way. Turn off the water at its source, remove the valve, and see if water flow is then adequate. If not, the problem is between the valve and where it connects to the t junction

if you are on a combination system it could be a safety tool. for about 40 quid a decent plumber will service the system and restore the pressure to its proper setting

From your description xenon has the right answer. Unbalanced pressures.
