From: Heat & Glo Fireplaces
Escape from Heat & Glo provides warmth and looks with styling choices, a big view of flames through anti-reflective glass, 25 percent more heat, and smart control with IntelliFire Touch. It can improve energy efficiency from 15 to 70 percent, saving up to $200 a year in heating costs. Direct Vent technology uses outside air for combustion, which expels 100 percent of the exhaust. Just run a gas line to the fireplace, run vent lines through the chimney and install/connect the new unit.
