    Just ordered one of the £40 Gainsborough's from my local B & Q and went through Quidco - they are offering £2 for a Reserve and Collect per basket, not per item, but only ordered the shower so £38 - result.

    Neat post mate.

    Factual. Explicit. Concise. Perfect.

    Thanks... I can make use of this :-D cheers

    Er... connect to cold water supply, connect to its own earth with grounding rod if necessary, if using a 10kw then you'll need some 16mm cable I think (check) and perhaps you'll need to upgrade the wiring to the external supply to 25mm if not already at that level or above (not sure about UK standards). Install a Safe-T-cut with the right amps (remember physics ?) 10,000/220=45 amps so you'll need a 50 amp Safe-T-cut. Perhaps check your board has a good overall safety.

    Of course, get some help if you cannot do it yourself. easy enough for an amateur if it is just a replacement for an existing unit but not so easy if it is a new install.

    good advice but not all showers are the same.....eg power rating - for some people the shower wont work well at all

    i got this 9.5 KW version installed 2 weeks ago. It's not as powerful as my old shower (which was a 10.5KW version) obviously, but the difference is very noticeable.
    Decent enough but not the hottest and flow rate is not great either.

    Maybe better for en suite than main bathroom. Good for £40.

    Not good acvice in my opinion. Get aen electrician in, there is so much to consider when installing a shower, cable ratings for example.

    I'm sure this is cheap but electric showers are useless. That's not open to debate, it's a hard fact.

    You simply cannot heat water quickly enough on a domestic mains electricity supply to provide a good flow rate of water.

    In the summer, when the incoming water is warmer, and you might not want such a hot shower they can be just about acceptable. In the winter, they are useless.

    The only positive is the fact that you don't need a hot water supply so you can always have a shower.

    The fact that you have to ask means you shouldn't go near it with a ten-foot barge pole. Leave it to the experts, get an electrician to install it!
    dreaddan
    dont forget that as the bathroom/shower room is a specal location Part-P applys!
    IE you need a registerd spark to do the work or you need to inform the councel planning dept and have them inspect the work!

    It's not drivel. It's cold hard physics.

    Even if an 11kW electric shower were 100% efficient it cannot heat a sufficient volume of water to provide a good shower. It can heat a little bit of water well, and a lot of water poorly.

    The choice with an electric shower is ALWAYS heat or flow.

    So we're on economy 7, have a hotwater tank, cold water is direct from mains, there is no pre-existing shower installed.

    What type of shower will be best for us?

    And typically how much would an electrician charge for installation?

    Cheers

    Nice 1, nice debate as well, couple of interesting points,

    What is the alternative? I too would like a shower that blasts you. We have a combi boiler so could use that but with six people in the house theres a good chance someone will turn another tap on leaving you to freeze (or boil) in a drizzle of water.

    Utter crap ! :roll:

    My electric Mira Sport Shower is superb ...regardless of summer or winter !! :thumbsup:

    Technology is changing all the time......you'd be surprised what new ones can do now.

    I've always thought Gainborough to be a bit poor though but may be adequate fro some folk.

    Think about it first - you can waste an awful lot of water and fuel that way. Even if you don't give a stuff about the environment, it will hit you in the pocket. With that sort of shower it's easy to use more water than you would use for a bath.
    We have a combi boiler so could use that but with six people in the house theres a good chance someone will turn another tap on leaving you to freeze (or boil) in a drizzle of water.
    In that case your mains supply has inadequate flow, and so your solutions are either to spend an awful lot getting it upgraded, or to spend an awful lot going back to a gravity-fed system with a cistern in the loft and a hot water cylinder (and possibly a pump for the shower), throwing away your combi boiler in the process. It looks like you have been mis-sold a combi boiler for a property which is too large, unfortunately.

    Well not really. You can't break the laws of physics.

    Here is the problem - you are happy with your shower, which is fine. What you are not appreciating is that it gives out the same amount of hot water as any shower of the same power.
    Technology is changing all the time......you'd be surprised what new ones can do now.
    Exactly the same as the old ones of the same power. You can add as many bells and whistles as you like, but you won't get more heat out than the energy you put in. If you find a shower that does that, you've come across a free source of energy or a perpetual motion machine, and you can make your fortune.

    I've always thought Gainborough to be a bit poor though but may be adequate fro some folk.
    They may fall to bits in two minutes. What they will not do is produce less hot water than any other make of shower with the same power.

    Let's look at a 100% efficient 11.5Kw electric shower:

    11.5kW = 410000000 joules per hour, or about 700,000 joules per minute.

    You need 4 joules of energy to heat 1 gram of water by 1 degree C. To heat water for a shower you need to raise it from about 5 degrees to 40 degrees, a 35 degree rise.

    That 35 degree rise therefore needs 140 joules per gram, meaning our 700,000 joules can heat 5000 grams of water from mains temperature to shower temperature.

    5000 grams of water = 5 litres.

    So, the maximum possible amount of water an 11.5Kw shower can heat and supply is 5 litres in a minute, and that's at 100% efficiency.

    That's a dribble compared to a decent power shower which will deliver 15-18 litres of hot water from your tank.

    Disagree all you like boys, but them's the facts.

    Altogether now ..

    (to the tune of la cucaracha)

    When you're using the force of a Newton
    And the distance you move is a metre
    Then your work is just one newton-metre
    And the energy lost is one Joule!



    .. Sorry , thats in no way relevant :oops:

    It was beaten into me by a science teacher 30 years ago and has been stuck in my head ever since :roll:
