Effinity™ High-Efficiency Condensing Gas-Fired Unit Heater

Key Features

• Ultra-High Efficiency: Up to 97% thermal efficiency—the most efficient gas-fired unit heater in North America.
• Separated Combustion: drawing combustion air from outside to ensure that the unit will always have plenty of fresh, clean air for combustion while increasing the overall heating efficiency.
• Condensing Heat Exchanger: Stainless-steel secondary exchanger extracts more usable heat from exhaust gases, reducing energy waste.
• Reduced Carbon Footprint: Lower emissions and less fuel use support sustainability goals.
• Energy Saver Controls: as the temperature increases, the gas is disabled, and stratified ceiling air is used to heat the space below. Once the ceiling air temperature decreases, the gas re-engages and heats the air.
• Smart Combustion Control: Advanced design ensures consistent operation across varying conditions.
• Contractor Convenience Package: Featuring a condensate pump convenience outlet, unit on/off switch, heater function status indicator lights, and external terminals for thermostat wiring.
• Corrosion-Resistant Construction: Stainless steel and aluminized steel materials ensure long-lasting performance in humid or chemically exposed areas.
• Quiet, Balanced Airflow: Designed for noise-sensitive environments such as schools or retail spaces.
• Flexible Mounting Options: Ceiling or wall installation maximizes space.
• Venting Flexibility: Can be vented as either a two-pipe or concentric vent system with 3″ and 4″ PVC.
• BMS Integration Capability: Optional factory-installed Building Management Systems.
• ETL Certification: ETL certification for residential(size 110 and smaller only), commercial, and industrial use in the US and Canada.
• Proudly Designed, Engineered, and Assembled in the USA: Commitment to quality and craftsmanship in every unit.
