At our old house, for quite a long time, we had a Rayburn which did Cooking, DHW and CH. It worked splendidly in the Autumn, Winter and Spring, but in the Summer, when we had one, it was a pain. So during the Summer we ran an Immersion Heater and I installed a gas hob. We had an Immersion heater which we ran on a timer, generally in sympathy with the Economy 7 but with the ability to override it when required. We had two children at home at the time. The tank was well insulated and I don't remember any horrifying bills. That would be my option provided you don't want to go the whole hog as Mark suggests.
There is one other thing to remember; it's axiomatic that the conversion efficiency from Electricity to Heat (hot water) is 100%. That is never true with gas. Further, the supply of hot water from a heated tank is almost instant whereas there's a lot of waste, which generally doesn't get counted, while the gas heater gets going.
