I've been using a space heater since last month to supplement heat in my house.
I thought I would be saving money each month on my gas bill. But although my gas bill went down about $20.00 my electric bill went up to $175.00 vs the $75.00 I've been paying each month for electric.
I paid more this month on my electric bill to use the space heater and didn't save anything.
I just spent more money and could've turned up my gas furnace instead.
