Our take on the 80,000 BTU Two-Stage Upflow/Horizontal ECM Variable Speed Gas Furnace 80% AFUE

This is a two-stage, variable-speed gas furnace rated at 80% AFUE, with 80,000 BTU input and 64,000 BTU output. The ECM variable-speed blower and two-stage burner let it run at lower heat and airflow most of the time, which means steadier temperatures, quieter operation and less on-off cycling than a single-stage furnace. It installs upflow or horizontal and moves up to 1,700 CFM. It suits homeowners replacing an older 80% furnace who want better comfort without the venting changes a high-efficiency condensing unit requires. Against 90%+ condensing furnaces it gives up efficiency and needs a standard metal flue, but it avoids condensate lines and PVC venting.

Questions and answers

What does two-stage and variable speed mean here?
The burner has a low and a high stage, and the ECM blower varies its speed to match airflow demand. Most of the time it runs on low stage, which is quieter and keeps room temperatures more even than a single-stage furnace.
Can it run on propane?
Yes, but only with a conversion kit, which is not included. Use kit 904914 in the US or 904915 in Canada.
Does it need special venting?
No. At 80% AFUE it vents through a standard metal flue like most older furnaces, so it does not need PVC vent pipe or a condensate drain.
What size home is 80,000 BTU for?
It produces 64,000 BTU of output and up to 1,700 CFM, which generally suits a mid-size home. Have a contractor run a load calculation for your house rather than sizing by square footage alone.
Can it be installed horizontally?
Yes. It is configured for upflow or horizontal installation, which covers basement, closet and attic layouts.
What thermostat do I need?
A two-stage-capable thermostat to use both heating stages. A single-stage thermostat will run the furnace, but you lose the low-stage comfort benefit.
Where is the 80,000 BTU Two-Stage Upflow/Horizontal ECM Variable Speed Gas Furnace 80% AFUE cheapest?
