Whats the difference between electric shower and a power shower?
Question:Im looking to buy a shower, i dont know if i can have an electric shower or a power shower, all my hot water comes from a boiler upstairs, and the bathroom is downstairs, my neighbour told me i cant run a shower off the boiler due to low pressure, ( i dont think i have stored water as i can use as much as i like) This has not confused the hell out of me and now i dont know which to buy, can anybody help?
Answers:
1) An electric shower heats the water as it passes through, it is connected to a mains water supply and an electrical supply, normally 8.5 - 10 kw for a good flow rate.
2) A power shower is a pump which will boost your water pressure if it is not high enough for a good flow. It connects to CISTERN FED hot and cold supplies and can be thermostatically controlled. It delivers the mixed water at a good pressure to a showerhead.
3) Since you say that you have a boiler and no storage tank (or hot water cylinder??) then you must have a combi boiler, which is already high pressure, in which case your best solution would be to install a thermostatic mixer designed for a Combi.
Look at this Mira chart to help you choose a model.

an electric shower only deposits the heated water at the same pressure as your cold water mains which is variable depending on where you stay and consumer demand. a power shower has it's own built in water pump which deposits the heated water at a pressure which you can control from the regulator on the front.

You can have either. (I have both, one in the bathroom & one in a shower room)
A power shower will pump the hot water from your tank so no need to worry about pressure. An electric shower heats cold water integrally.
I would go for a pump somewhere near the hot water tank, so when you have a shower you won't hear the pump winning.
Depends on the type of boiler you have and it's output. If you do not have a seperate hot water tank then you have a combination boiler and cannot have a shower with a seperate water pump (a power shower). It is possible to run a shower from a combination boiler, how powerful it is is purely down to the number of litres per minute it outputs. Look up the make and model on the internet to find out. Buy a cheap shower attachment from B&Q to push fit over your existing taps to test it
An electric shower is a small unit that fits in the cold water line and heats the water as it passes through the unit. It's usually mounted inside the shower cubicle. They are relatively cheap to install since they just need the cold water feed and a heavy power cable. Often they draw 7 to 9 kW so the electrical system needs to be able to take this load.
A power shower is an electric pump that boosts low water pressure to provide a powerful spray at the power head. Because it draws hot water from the boiler, its not recommended to use a power shower with a combi-boiler.
Best advice is to get someone who really knows what they are looking at to check your system out.
Listen to keefy not tilly,he's got it right she's slightly lost the plot
An electric shower uses only a cold water supply and heats the water electrically in the shower. A power shower needs a hot and cold water supply that is boosted up to a higher pressure via a booster water pump.
As far as installing the shower downstairs, you will have height pressure cold water and low pressure hot water. You can use a power shower but you will need to adjust the outlet pressure from the pump from the the cold water side.
The easy solution would be to install an electric shower as you do not need to worry about having the hot water boiler on to ensure you have hot water.
An electric shower just runs of the mains pressure and I believe a power shower is fitted with a pump which boosts the water flow output. You could use either but you need to check and see if your water pressure is sufficient to run a power shower. Neither of them rely on your boiler as they are mostly self contained and have their own instantaneous heating system therefor only heating the water that you actually use and not storing it. More economical.
a powa sowa has its own pump.
you can have what ever you want. it's just a case of how much money you want to spend. the cheapest way to get a powerful shower is a top of the range electric shower as it is it's own boiler.
