Who it's for
Heating a home that needs about 127,000 BTU/h of delivered heat, replacing an older oil furnace.
The standout number
AFUE 83% — a non-condensing furnace; efficient models reach 95–98%.
The catch
At AFUE 83% it wastes more fuel up the flue than a 95%+ condensing furnace — worth the math where winters are long.

Rebates & incentives
High-efficiency gas furnaces (95%+ AFUE) sometimes qualify for utility rebates, but the bigger incentive money in 2026 targets heat pumps, not furnaces. The federal 25C credit expired December 31, 2025. Check what applies where you live on our rebates page, and compare a furnace's running cost against a heat pump on our operating-cost calculator.

Frequently asked questions
How efficient is the THERMO PRIDE OT16-125*BP-B?
Its AFUE is 83%, meaning 83% of the oil it burns becomes heat in your home and the rest goes up the flue. Below 90% it is a non-condensing furnace; the high-efficiency class runs 95–98% AFUE.
What does the THERMO PRIDE OT16-125*BP-B cost to run?
About $20.24 per MMBtu of delivered heat at U.S. average oil prices, roughly 63% less than electric resistance heat. Your local fuel price changes the number — run it in our operating-cost calculator.
How big is the THERMO PRIDE OT16-125*BP-B?
It delivers about 127 MBTUH (127,000 BTU/h) of heat from a 156 MBTUH input. Furnace sizing should follow a Manual J load calculation, not a rule of thumb — an oversized furnace short-cycles and wastes fuel.
Does the THERMO PRIDE OT16-125*BP-B have a variable-speed blower?
The record doesn't flag an ECM blower for this model, so assume a standard PSC blower motor unless the spec sheet says otherwise.
Where can I buy the THERMO PRIDE OT16-125*BP-B?
It's listed online at HVACDirect, but gas furnaces must be installed and gas-fitted by a licensed pro for safety and the warranty.
