Buying an electric shower - basic advice needed please.

[scotster]

I have an electric shower in a loft conversion that looks like it belongs in a museum.

I am replacing it as part of refurb.

1) Do I need a pumped system?
It has one cold feed (15mm) which I assume is mains pressure. The pressure from the sink cold tap next to the shower it is not particulary good when on full bore. I have shower unit removed so I can give you litres/min if that helps.
Pressure in my ground floor taps is fine and I am surprised it drops so much with only a 7m difference....

2) If I need a pump do I buy a seprate pump or an integrated one? Your opinion please.

3) What pressure pump please? Any good sites to get one from?

4) What kW do you recommend? I assume the higher the faster the flow when the temp is up high?

Any help welcome.

Rgds, Scott.

I should mention that the flow from the shower before I took it off the wall could best be described as 'just adaquate'

What you need, depends on you!
You can't pump the mains, and you rarely would have any difficulty running an electric shower at ground level from the mains as the flow required is low.
I suggest you google for descriptions of shower types, it's out there...

Cheers.

So I cant pump a mains feed? OK. Kind of makes sense

So I just need a decent kW rating?

This is the shower in the loft - just to be clear.

right. have u got a combi boiler that produces instant hot water or do u have a hot water copper cylinder in a hotpress. i take it if u have done a upstairs loft conversion then u have no cold water storage tanks and may have an unvented mains pressure cylinder let us know this b4 we continue to advise the best way around ur problem chap.

and bear in mind you might have to upgrade the electrics as well
