recently moved into my new house in a village that has no gas. so i have an economy 7 hot water cylinder and a GEC 3 phase boiler / massive storage heater for the rads, this charges over night on economy 7. the GEC boiler is massive about the size of an american fridge freezer, so i want rid of it. i have looked at a 3 phase boiler 24 kw for the rads and possibly the hot water tank ( don't want combi ) but was wondering if it is more expensive to do this than run the eco 7 cylinder, or weather i should scrap and just run oil or LPG
