Efficient Electric water storage heaters

[Neal Unitt-Jones]

On holiday in France the farmhose we stayed in had a giant (2m high) electric water heater in the cellar. It fed mains pressure hot water to the house above. The owner said it was great and the bills weren't high. My old gravity fed indirect effort which heats off a gas boiler could do with replacing. I'm fortunate to have a cellar, one of these giant things would be perfect. The only references I can find to electric water heating are the good (ie bad) old immersion heater.

Can anybody point me to websites for something better?

If you believe a Frenchman on matter plumbing you are stark raving bonkers - they invented the Saniflo.

All electric water heaters are (at the point of delivery) 100% efficient. All you can do after that is improve insulation etc to hold that heat in but there is nothing more efficient than the bog standard immersion heater.

As with all forms of peak rate electric heating it is still very expensive - because electricity is expensive compared with other fuels - but it is perfectly efficient.

Stick to gas as electricity is 3 to 3 times more expensive to run. Unvented indirect cylinders heat by gas boilers are available here. better still fit a heat bank.

Cable loss can make that 97%.

Hi Neal,

If you already have the heating system installed, then why not extend the pipework and fit one of these in the cellar:

Power station loss can make that less than 40%

From meter to element.

From generator to element. And if a coal burning station the most polluting.

(go to thermal storage).

Yup, that looks like the puppy, thanks. NUJ
