US Stoves Large Coal Furnace (2,500 sq. ft.) CF1440E

Built for serious heat and all-day performance, the US Stove CF1440E coal-only furnace delivers up to 140,000 BTU/hr and comfortably warms spaces up to 2,500 sq. ft. This furnace is designed to work in conjunction with your existing HVAC ductwork, connecting to your home's existing duct system to distribute heat throughout the house rather than warming a single room directly. A large 5.2 cu. ft. firebox, measuring 24.25" x 41.25" x 40.25" and weighing 450 lbs., is built for long, steady coal burns at a larger scale than the CF1330E. The furnace ships without blowers, requiring two Model 80874P blowers (sold separately) to provide powerful heat circulation through the connected ductwork. Reliable, rugged, and built to move serious heat, this furnace is ready to integrate into an existing forced-air heating system.

How The US Stove CF1440E Compares To The CF1330E And Ashley AW3200E-P

Homeowners evaluating how to add serious solid-fuel heat to a larger home usually face this question: should I choose the smaller CF1330E for up to 2,000 sq. ft. of ducted coal heat, select this CF1440E for the largest ducted coal furnace coverage at 2,500 sq. ft., or go with the standalone Ashley AW3200E-P wood stove for a viewable-flame alternative without ductwork integration.

Here's the honest comparison:

Why The US Stove CF1440E Is Worth The Investment

This isn't just a bigger furnace, it's the largest ducted coal furnace in the US Stove lineup, giving homeowners with bigger homes the ability to feed serious coal heat into their existing ductwork without stepping down to a smaller-capacity unit.

The CF1440E specifically addresses the needs of homeowners heating larger spaces up to 2,500 sq. ft. who want to supplement or reduce reliance on their primary furnace with a ducted coal system built for maximum output.

Turns Existing Ductwork Into A High-Capacity Coal Heating System. Designed to work in conjunction with your existing HVAC ductwork, the CF1440E's larger 5.2 cu. ft. firebox and 140,000 BTU/hr output push more heat through your existing duct system than the smaller CF1330E, covering an extra 500 sq. ft. of space.

Built For Serious, All-Day Heat

• Up to 140,000 BTU/hr of output comfortably warms spaces up to 2,500 sq. ft.
• A 5.2 cu. ft. firebox, the largest in the coal furnace lineup, is designed for long, steady burns
• Rugged furnace-style construction is built to move serious heat day after day

Engineered For HVAC Integration

• Designed to connect directly with existing HVAC ductwork for whole-home heat distribution
• Two required Model 80874P blowers (sold separately) provide powerful heat circulation once paired with the furnace
• At 450 lbs., the unit is built as a substantial, permanent heating fixture rather than a portable stove

Real Savings

• Coal fuel can offer a longer, steadier burn than wood, reducing the frequency of refueling
• Integrating with existing ductwork avoids the cost of running separate heat sources for different rooms
• Supplementing furnace heat with a coal furnace can reduce reliance on higher-cost gas or electric heating
• Free shipping and no sales tax through Summit Forge Supply keeps the total cost down compared to buying elsewhere and paying tax and freight separately

The Bottom Line Homeowners with larger homes up to 2,500 sq. ft. who want to feed serious coal heat directly into their existing HVAC ductwork can't get that same capacity from the smaller CF1330E. The US Stove CF1440E is built with a 5.2 cu. ft. firebox and up to 140,000 BTU/hr of output, so it delivers the most ducted coal heat in the US Stove furnace lineup. Keep in mind the two required blowers are sold separately. For anyone with a larger home wanting maximum coal heat through existing ductwork, this is the furnace built to make it work.
