Please see link to trusted site for fuel costings as you can see it the costs for kW/h for oil is around 5.36p against standard rate electric of 14.05p, even allowing for some heat loss from boiler & pipes it is still much cheaper to heat your hot water via the boiler rather than the immersion.
As I had already written this before thread was closed by the eyes in the sky, I thought I would post anyway, think it is based on prices last Feb so may have dropped even more.
I might have to go get my OFTEC. LOL
