Electric water heater

Quirkyjester

Firstly apologies if this is the wrong forum, new here and trying to find my way around!

I'd like some advice on heating hot water for a bath shower, taps only.

I have a cottage which only has an immersion tank, due to the size of it and position of the tank.. it's small and doesn't keep the water hot for long or hold much.

I was wondering if anyone knows of an electric water heater system which would heat the water as you use it, similar to a boiler. Theres no mains gas and no option for LPG or an oil tank.

Thanks in advance

There are electric showers that heat water as you use it. Needs to be expertly installed as it usually requires 45A or even a 60A circuit.

Or just get yourself a bigger hot water storage tank
They even make especially large ones for E7 usage designed to allow you to heat your entire day's water at cheap rate (often about 50% the cost of normal rate)

Unfortunately, due to the layout a bigger tank isn't an option so was wondering if theres a recommended system which heats hot water directly.

Heating water as it flows (rather than slowly heating up a tank full and storing it until required) requires a very high current. Even the more powerful electric showers described above have a relatively low flow rate compared to a normal shower fed from a tank. It would take an age to fill a bath.

Even a gas combi boiler, which gives a far better shower than any electric, still takes quite a while to fill a bath.

So I think your options are either a bigger tank, if you can somehow fit it in, or keep the existing one supplemented by an electric shower.

If you are using off-peak E7 at present to heat your water, bear in mind that instantaneous electrical heating at peak rates will significantly increase your costs.

Thanks for the replies �� think the easiest option is for an electric shower in that case and make do with the small tank... The tank cannot be bigger unless a wall is knocked down and moved. Joy's of old properties ��
