For an average one bedroom one occupant apartment.
I know this is kind of a specific ask but if you have a gas water electric fire how much do you pay each month?

Thanks
Answers:    Independ I would guess your gas sea heater will add just about $20.00 cost, to your bill each month. This all depends on the cost of therm of your nouns.
It depends o how much you use it. If you don` turn it off it will cost at least2,6598$.
