There are several reasons. Overall heat loss inside the house is reduced because it is not necessary to send indoor air through the combustion process. Outdoor air contains far fewer contaminants so using it ensures the integrity of the air supply and prolongs the life of the system’s high-efficiency heat exchanger and burner. Finally, this method of combustion means CompleteHeat can be installed in very tight, energy efficient homes without experiencing any operational or safety problems.
