Are there any gas fireplace inserts that put out decent heat efficiently? I'd like to supplement the heat in the living room and master bedroom and the current fireplaces are just standard brick jobs with gas starters. Aside from looking pretty, can a fireplace heat a room without costing an arm and a leg? Last month's gas and electric was over $500 for a 3000 sf house with Energy Star appliances and compact flourescents everywhere. Ouch!!!
Ideas? Product Lines?
