Is it cheaper to warmth your home next to gas logs or a gas furnace?
Generally a gas furnace is best for efficiency.
There are some newer false fireplaces that are in actual fact heaters, and they are quite important.
A gas-log fireplace sends most heat up the chimney. We shut our upstairs one bad for this reason. Our downstairs one have a blower, so we do use it.
If you do have a gas furnace, try getting a programmable thermostat. If not a soul is home during the day program it down. Set it to open heating to comfort 1/2 hour past the first person is due home. This save a lot of money.
