A high-efficiency, gas-fired heat pipe warm air residential heating system is being developed. The system features a heat pipe exchanger, a powered combustion burner designed for continuous modulation down to 25 percent of full output, and individually controlled room registers. The heat pipe heat exchanger gives high heat transfer coefficients, which facilitate a lightweight and compact design. The powered combustion system allows both low stack losses and low NOx and CO emissions. Thermostatically controlled individual room registers allow room temperatures to be determined by room use and comfort requirements. The system can be modulated from 25,000 to 100,000 Btu/h to match heat load requirements. This design achieves a steady-state efficiency of over 85 percent, with seasonal efficiencies approaching steady-state values.
