I have a 2 bedroom apartment with electric heat and hot water. Each room has it's own thermostat so we only use it when we are in the room, otherwise it stays off. I am on a budget plan with National Grid so I pay about the same amount every month, currently about $150. So I pay $150 no matter the month. That is subject to change but has never been @25 more or less than $150. If I wasn't on a budget plan I'd be paying about $100 in the summer and at least $300 in the winter months.
