A combination of insulation improvements, air sealing, and winterization projects will help ensure your heating system is efficient and long-lasting. The worse your home's insulation, the harder your heating and cooling system will have to work.
The flames from the burner component heat a metal heat exchanger. The heat circulates through the looped tubes of the heat exchanger, transferring the heat to air.
