I use my oil boiler but have previously used the immersion heater at night (economy 7) and a boost from the oil boiler in the afternoon.Does anyone know what's the most cost effective way of heating a hot water tank.
Electricity at 15p kw or oil fired boiler?
But since both oil and electric prices have skyward just stuck to oil.
15p sounds cheap, I’m paying 24p night rate!
