Our take on the 80,000 BTU Single-Stage Upflow/Horizontal ECM Multi Speed Gas Furnace 80% AFUE 115/60/1 CFM: 2000

This is an 80,000 BTU input gas furnace with 64,000 BTU output and 80% AFUE, built for upflow or horizontal installation. It uses a single-stage burner with a 4-speed ECM blower rated up to 2,000 CFM, so it runs at full fire and steps airflow rather than modulating heat. It is not Energy Star rated and needs a propane conversion kit (LPT-03, sold separately) for LP use. At $799 at Surplus City as of November 7, 2026, it sits at the low end of its recent range across the five stores that list it new.

Pros
  • 80,000 BTU input gives roughly 64,000 BTU of usable heat, enough for a mid-size home in a moderate climate
  • 4-speed ECM blower moves up to 2,000 CFM and uses less power than a PSC motor at low speeds
  • Upflow and horizontal configurations cover basements, closets and attics
  • Simple single-stage design with fewer parts to fail than a two-stage or modulating unit
  • Made in the USA
Cons
  • 80% AFUE is below the 90%+ of condensing furnaces, so more heat goes up the flue
  • Single-stage means full-fire cycling and wider temperature swings than a two-stage unit
  • Propane conversion kit LPT-03 is not included
  • Non-communicating controls limit pairing with smart or modulating thermostats
  • Heavy unit (105–132 lbs depending on source) needs two people to set

Questions and answers

Is 80,000 BTU enough for my house?
It delivers about 64,000 BTU of output, which typically heats a mid-size home in a moderate climate. Have a contractor run a load calculation; oversizing causes short cycling.
Can this furnace run on propane?
Yes, but only with the LPT-03 propane conversion kit, which is not included. Natural gas works out of the box.
Does 80% AFUE matter compared with a 90%+ furnace?
It does. A condensing furnace captures more heat per dollar of gas, but it needs PVC venting and a drain. This unit vents through a 4-inch flue and is cheaper to buy.
What is the difference between input and output BTU?
Input is the gas burned (80,000 BTU); output is the heat delivered (64,000 BTU). The 20% gap is the flue loss that defines 80% AFUE.
Is it compatible with a smart thermostat?
It uses non-communicating controls, so a standard 24V smart thermostat works for on/off heating, but you won't get modulating or communicating features.
When is the price lowest?
Furnace prices move with heating season. The current $799 at Surplus City as of November 7, 2026 is at the low end of its recent range, so waiting for spring clearance is the main way to beat it.
Where is the 80,000 BTU Single-Stage Upflow/Horizontal ECM Multi Speed Gas Furnace 80% AFUE 115/60/1 CFM: 2000 cheapest?
At Surplus City, for $799.00, 24% under what the other stores charge, as of our latest check.
Where can I buy the 80,000 BTU Single-Stage Upflow/Horizontal ECM Multi Speed Gas Furnace 80% AFUE 115/60/1 CFM: 2000?
