Fireplace forced air heating apparatus comprises a heat exchanger having a pair of tubes, which may serve as andirons, communicating with a plenum within the heat exchanger and extending outwardly to the front of the fireplace. The tubes connect with duct work including a reversible fan, a hot...
which heats approximately 35 million homes.Forced-air heatershave a furnace, which can be operated through natural gas, electricity or oil, that heats up air. This hot air travels through a series of ducts to registers, which allows the air to blow into the room. Forced-air heating systems...
The present invention relates to a forced-air electric heater control system for HVAC systems. One embodiment utilizes two heat sensors which are positioned upstream and downstream, equidistant from the heating element(s). The control system, in this embodiment, takes the difference between the tempe...
typically a large furnace or air conditioner, and moves it through the house in large pipes called heating ducts. The return system brings cooler air to the heating device. An encased electric fan, called a blower, moves the air through the system as needed. ...
