US Stoves Small Coal Furnace (2,000 sq. ft.) CF1330E

Built for serious heat and all-day performance, the US Stove CF1330E coal-only furnace delivers up to 120,000 BTU/hr and comfortably warms spaces up to 2,000 sq. ft. This furnace is designed to work in conjunction with your existing HVAC ductwork, connecting to your home's existing duct system rather than heating a single room on its own. A spacious 3.0 cu. ft. firebox, measuring 21" x 34" x 40.25" and weighing 350 lbs., is built for long, steady coal burns. The furnace ships without a blower, requiring one Model 80874P blower (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 CF1330E Compares To The Ashley AW40 And CF1440E

Homeowners evaluating how to add solid-fuel heat to an existing HVAC system usually face this question: should I choose the Ashley AW40 for a standalone wood circulator that heats a single space directly, select this CF1330E to integrate coal heat into existing ductwork for up to 2,000 sq. ft., or step up to the larger CF1440E for even bigger coverage.

Here's the honest comparison:

Why The US Stove CF1330E Is Worth The Investment

This isn't just a standalone stove, it's a furnace-integrated heating system, giving homeowners the ability to add serious coal heat directly into their existing ductwork instead of relying on a single-room stove to warm the whole house.

The CF1330E specifically addresses the needs of homeowners who want to supplement or reduce reliance on their primary furnace by feeding coal-generated heat directly into the home's existing HVAC distribution system.

Turns Existing Ductwork Into A Coal-Fed Heating System. Designed to work in conjunction with your existing HVAC ductwork, the CF1330E lets coal heat flow through the same ducts your furnace already uses, so warmth reaches every connected room instead of staying concentrated in one space.

Built For Serious, All-Day Heat

• Up to 120,000 BTU/hr of output comfortably warms spaces up to 2,000 sq. ft.
• A 3.0 cu. ft. firebox is designed for long, steady burns that reduce how often the furnace needs to be reloaded
• 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
• A required Model 80874P blower (sold separately) provides powerful heat circulation once paired with the furnace
• At 350 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 who want to feed serious coal heat directly into their existing HVAC ductwork can't get that whole-home distribution from a standalone circulator like the Ashley AW40. The US Stove CF1330E is built with a 3.0 cu. ft. firebox and up to 120,000 BTU/hr of output, so it delivers long, steady heat through the ductwork you already have. Keep in mind the required blower is sold separately. For anyone wanting to supplement their furnace with serious coal heat, this is the furnace built to make it work.
