I've googled and checked the FAQ but not found anything specific to
this
problem.

I would like fit a decent shower in my bathroom as part of a
shower/bath
combination. Its a small flat with basic plumbing, 1 cold water tank
and
1 hot water cylinder heated by an electric immersion heater, taps are
gravity fed (except the kitchen cold mains tap).

The problem is that the shower head height is less than 10cm below the
water level in the cold water tank and also heating the water is an
issue.

From googling it seems I would need a negative head pump like a ST
monsoon to deal with the head height. But what about heating the water?

What's wrong with the immersion heater for heating the water?

There nothing wrong with it, except I was kinda thinking along the lines
of something that you could have an 'instant' shower with. With the
immersion heater you'd have to wait till the water heated up first
before having a shower.

If I was going to use the immersion for heating is there a decent brand
of shower unit you would recommend that would do the job with the pump
attached?

Im beginning to think I could get away with this option unless the
alternative of an electric shower is not too much more expensive.

If your hot water cylinder is well insulated and your thermostat is working
ok, then using an immersion heater for primary heating, would be best left
on constantly, to be most cost effective.

Most of the decent brands would do this job and probably most of the cheap
ones too.

As for putting in an electric shower depending on if you can get a plumber
who is part P registered, or a spark who is willing to do a bit of pluming,
might cost between £250 and £350 all in.
