Would it be more economical to buy a load of tea lights from IKEA and heat the tank 24/7 from those?
That's not helpful is it?
Somebody comes to this site for a little bit of help / advice and that's the best you can do?
You should be ashamed!
EVERYBODY knows......tea-lights are cheaper at poundland!

I am of the opinion if you stick 230v ac directly into the cylinder , I swear this will heat your water more gently and not use much enrgy as you are not using the element, so the water heats directly. 
But don't forget to earth the tank,if you want to live to feel you are ssaving money, and don't forget even if the electric is more expensive, it is also more efficient (almost 100%) and so you save on the cost of having a cylinder serviced by an RGI each year savinbg what around 75 quid|!

the generation, distribution and supply of electricity is not at all 100% efficient.
just because the chimney is in the power station and you can't see it, and you can't see the transformers and cables warming the sky doesn't mean it isn't happening.

LOL John, I meant at home, if you use 1kw of electricity you use all of that in the tank to heat water, excluding any losses through the tank, because loses cancels out as you would still be heating water with gas and the losses are still there, but when you burn gas, you loose anything between 10% to 30% in flue heat depending on your boiler's efficiency.
So a 1kwh of gas will only yield around 700watts as 300watts gone through the flue! (@70% efficiency)

Yet another plumber carrying out non-compliant electrical work...
My boiler is much more efficient than yours then.
And of course electricity costs three times as much as gas per kWh (the extra cost is partly used to pay for the low efficiency of the generation, transmission and distribution of electricity).
So gas still works out much cheaper.
I've lost track of the number of times I've had "conversations" with people that genuinely believe that it costs the same to heat "a full tank" of water when you only drew off (say) half a tank as it would if you started from cold. So this sort of thing doesn't surprise me in the least.
I've also seen comments in here to the effect that thermal stores are inefficient because "you throw away half the heat by mixing with cold water" (referring to the DHW tempering valve normally installed)

got a link to that conversation ? I would be interested to see who made the comments.
Sorry, can't remember the exact words used, and can't find it with a search - too many hits on "thermal store" and "mixed" Was definitely on the lines of heat being "wasted" when the hot water is mixed down in the TMV.

Fair enough. I doubt a towel radiator element is going to last more than a year. I think the best bit was the epilogue: "After some testing it was found that a 250watt panel was required"
He really made life difficult for himself. If he just wanted to heat hot water why not install a twin coil cylinder and pumped system.
