What type of shower would you need

With showers it depends on the type of water boiler you have in your house as to       
what kind of shower system you should have installed as each type of boiler can       
handle different types of shower due to power and pressure of water.       
The different types of boiler and showers to suit their system are as follows       
       
Boilers that consist of a copper cylinder in the airing  cupboard require an         
electric shower ideally.These are also good for those wishing to save energy as         
they only heat the water when needed instead of having a constant tank of water       
pre heated.They  also run on a different water circuit to the rest  of the house so         
can be fitted in any house no matter what the boiler type.       
       
where the boiler has its copper cylinder placed in the airing cupboard but the         
cold tank of water is held in the attic it will require a power shower.With power       
showers they only pump the water they don’t heat it so the water still needs to be       
heated through the main water system that heats the water.       
       
With a boiler that has a cylinder in the airing cupboard with an expansion vessel       
on the side of the cylinder you would need to fit a mixer shower.There are two       
types of mixer shower there is the manual (which does not have a constantly       
maintained temperature if the water flow is changed)and the thermostatic system       
that has an in built temperature control.The thermostatic tend to cost a little more       
but prevent dramatic temperature change if for example some one turns on a tap       
downstairs or flushes the toilet.This making them the safer option if they are used       
by children or elderly people.       
       
A house that has no airing cupboard and has a combination boiler will have a         
mixer shower fitted.However the showers used with combination boilers are         
made specifically for use with this type of boiler.Another advantage that comes       
with the mixer showers is that most of the pipe work at the end of installation       
is hidden from view this meaning the area round the shower will look neater.       
       
For a cheaper option there is always the push on mixer which you simply push       
on over the tap spouts and the taps are used to adjust the temperature of the       
water.However this method is mainly used as a temporary solution as the hose       
connection to the taps is easily dislodged if knocked and controlling the         
temperature can be difficult.       
It is highly important to ensure you have the right shower  for your heating       
system so make sure it is professionally installed with correct advice.
