When buying an electric wall shower.?

Question

I need one that fits on the wall above my bath.I have fitted a shower screen.
What is the best shower to run off a cold water source. I am told that the Kw rating is important. Any ideas please.

Answer 1

If you're going for an electric shower then:
a) You'll need mains pressure cold water (not gravity fed).
b) You'll also need a dedicated wire going directly to the fuse box with its own fuse (10mm squared wire needed - possibly 6mm if the shower is 8.5kw or less and not more than 10m from the fuse box).
If you want a decent flow rate, you need to go for at least a 9.5 kw (possibly a 10.5kw).

Answer 2

Your current boiler is probably 50-70% eefficient. Fitting a Condensing boiler with a sedbuk A, rating of over 90% will save you the cost of the boiler over a 15 year lifespan. The previous advice of fitting an unvented system is probably your best bet especially if there are 4 of you waiting to use the shower. Another option is to fit and electric power shower which doubles as a back up if you are fitting a combi boiler. Remember to have your system sized correctly if you do fit a condensing boiler because if it isn't it won't condense. Current regs insist on energy efficient controls like trv's, lagging of exposed pipes and zoning so make sure you get a reputable installer.

Answer 3

The higher the Kilowatt rating the hotter the water is in comparison to the same water flow. If you want a power shower installed then I would think that you need a higher KW rating for that. Check with a professional shower retailer, they will offer sound advice.

Answer 4

Mira sport is the best on the market ...get at least 9kw ..the reason for the high kw ..is ..water is much colder in winter and you need the high kw to heat it efficiently ...note ..what ver shower you buy you will need a new cable running back to the fuse box with its own mcb(mains circuit breaker )

Answer 5

First of all you need to identify what type of plumbing system your home has, presuming its gravity fed (having a hot water cylinder in a cupboard and a cold water storage cistern in the loft), you could have either a power shower or an ordinary electric shower the only difference is a power shower has a built- in electric pump (ideal if you have low water pressure in your home) if pressures not a problem then an ordinary one will be good enough. the higher the kilowatt rating the more powerful the shower. just remember to use a good and competent sparky/plumber. hope this helps

Answer 6

9.5 is plenty. Make sure the cable to the fuse is {which should be 30amp] is strong enough otherwise it will keep tripping'
