The High Efficiency Furnace
The high efficiency furnace, also referred to as a condensing furnace, differs from a conventional furnace in that it operates by recovering warm air from the combustion chamber and using this warm air to heat the supply air. A secondary heat exchanger warms untreated air on the return side, and this warm air is then drawn and delivered back into the heating system. The traditional furnaces tend to lose waste heat due to flue gases which are not effectively trapped within the larger chamber. The combustion air can be leaked into the heating system, and the warm air can rise and escape the flue system.Read More →
