Yes I meant 2 months continuous use. We have plenty of hot drinks and cook 2 meals a day in the van so the hob is on the go quite a lot. We didn't used to have a water heater, so that ate gas heating water for washing up etc when not on a campsite with facilities. However we now have a small electric heater and hot water cylinder that runs off electric hook up or will trickle feed when in transit .
Sacrificed part of a cupboard but will save on gas.
