Hot water heating?? Help

Hi, I have recently had my rubbish economy 7 wet radiator heating system removed (as it was ancient and ineffective). I have replaced it with haverland gel electric radiators that are superb and I no longer need econ7. Now I have a dilemma. How do I heat my hot water?

The current system was a huge 240litre immersion cylinder (heated overnight on e7). I can't afford to keep heating this huge monstrosity on normal rate electric, neither do I need that much water. I have an electric shower, hardly use the bath and have a cold fill washing machine so only need hot water for hand washing and washing up.

I live in a remote village that does not have gas. Could someone please help or advise the best system for this?

Thanks

 

Thanks plumber boy I did think of that but I was hoping to get rid of the huge immersion all together if possible. I would also need two water heaters one for bathroom and one for kitchen.

 

Thank you, I will look into it. I like the idea of a smaller cylinder. That way I can still have running hot water, but it won't cost me a fortune to heat the thing. The smallest size I have seen is about 40 litres. Do you think this will be adequate?! Only two of us in the house, and like I say everything else is independent.
