EcoTemp 95% Single Stage 60K BTU Gas Furnace, WFSX060B048B
For the average-size home that needs dependable gas heat and a blower strong enough for central air, the EcoTemp WFSX060B048B hits the middle of the range. This 60,000 BTU input condensing furnace produces 58,000 BTU of heating output and reaches 97.0% AFUE in upflow or horizontal configurations, qualifying for ENERGY STAR version 5.0 North in those positions. Its 3/4 HP, 18-speed constant torque ECM blower supports up to a 1,600 CFM cooling designation, making it a practical choice for homeowners, HVAC contractors, and property managers upgrading from an older 80% furnace or building a new air conditioner, gas furnace and cased coil system.
Is a 60,000 BTU Gas Furnace the Right Size?
Sixty thousand BTU is one of the most common residential furnace sizes because it covers a broad band of moderate heating loads, from mid-size ranch homes to two-story houses with good insulation. The right answer still comes from a room-by-room heat-loss calculation: EcoTemp's literature directs installers to size the WFSX to 100 percent of the design heating load using ACCA Manual J and S or an equivalent engineering method.
Where a 60K furnace shines is homes that outgrew a 40K unit's heat or airflow but do not need the bulk of an 80K. Climate zone and winter design temperature, attic insulation depth, the number and quality of windows, duct leakage, and installation altitude (above 2,000 ft., U.S. ratings drop 4 percent per 1,000 ft. of elevation) all shift the target. Oversizing a condensing furnace can shorten its life and contribute to vent freeze-up, so resist rounding up "just in case."
Ideal for: Mid-size single-family homes, furnace changeouts from older 60K–75K standard-efficiency units, and split systems with an air conditioner up to about 4 tons (1,600 CFM cooling designation).
Need more capacity? Step up to the EcoTemp 95% Single Stage 80K BTU Gas Furnace, WFSX080B048B, which uses the same 17-1/2" cabinet but adds 20,000 BTU of input for colder climates or larger floor plans.
Recommended heating applications are general guidelines only. Actual furnace sizing depends on a heat-load calculation, insulation, climate, ductwork, elevation, and air-conditioning match. Request free sizing assistance, contact Budget Heating, or call 813-885-7999.

Specifications & Manuals
The 060B048 data in these documents covers air delivery at each of the 18 speed taps, vent length tables by altitude, and wiring for single-stage cooling. Compare other natural gas and LP furnaces, pair a 3.5–4 ton cased coil, or add a programmable thermostat.
Frequently Asked Questions
How do I know if 60,000 BTU is enough heat for my home?
Have a Manual J heat-loss calculation done. If your design heating load falls at or below the WFSX060B048B's 58,000 BTUh output (after any altitude derate), this size is a good fit. If the load is higher, the 80K WFSX080B048B is the next step.
What AFUE rating does the WFSX060B048B achieve in downflow?
The WFSX060B048B is rated 97.0% AFUE in upflow and horizontal installations and 95.0% AFUE when installed downflow, according to the WFSX product data.
Does the WFSX060B048B qualify for ENERGY STAR?
Yes. The manufacturer lists the 060B048 as meeting ENERGY STAR version 5.0 North criteria in upflow/horizontal and ENERGY STAR version 5.0 South criteria in downflow, based on orientation-specific AFUE.
How much cooling airflow can the WFSX060B048B blower deliver?
The 3/4 HP ECM blower provides a cooling airflow range of 315–1,580 CFM at rated static, with a 1,600 CFM cooling designation in the model number. That generally supports single-stage air conditioners up to about 4 tons.
Can the WFSX060B048B run on propane?
Yes, with a factory-approved LP conversion kit, sold separately. The furnace ships set up for natural gas, and the conversion must be completed by a qualified installer following the kit instructions and rating plate.
How does the WFSX060B048B compare with the 40K WFSX040A030B?
The 60K model adds 19,000 BTUh of heating output, steps up from a 1/2 HP to a 3/4 HP blower, raises the cooling designation from 1,000 to 1,600 CFM, and uses a wider 17-1/2" cabinet versus 14-3/16". Upflow AFUE also climbs from 96.0% to 97.0%.
