A gas-burning insert is a great way to turn your non-efficient fireplace into an effective heating source, even if the power is out. The Enviro “Focus” is a mid-size insert for heating about 1200 square feet or less. This display model hasn’t been used and it has a screen door set over the glass to give it a nice look of a regular fireplace. Retail price is $2295, but we’re discounting this display model $500 to sell at $1795 for the insert, with installation not included. Free estimates available.
