How do I choose the right Reznor UEZ model for my building size?

Hello, thank you for reaching out. Choosing the right Reznor UEZ unit depends on square footage, ceiling height, insulation quality, climate conditions, and how quickly the space needs to recover heat. Lower-BTU models such as UEZ-55 and UEZ-85 are often selected for smaller garages or workshops, while larger models like UEZ-180 through UEZ-310 are better suited for warehouses, agricultural buildings, and larger commercial applications. If you have additional questions, please feel free to reach out over the phone to our Customer Service line at 1-888-901-5460. Have a great rest of your day.
