Osburn 2500 Pellet Stove — Homeowner Guide

Manufacturer: Osburn
Model: 2500 Pellet Stove
SKU: OP00025

What This Is

The Osburn 2500 is a freestanding pellet stove designed to heat your home using compressed wood pellets instead of traditional firewood. It automatically feeds fuel from a hopper into the burn chamber, giving you controlled, consistent heat without manually loading logs throughout the day.

This is a high-efficiency, EPA-certified pellet stove built for homeowners who want steady heat with less hands-on effort than a wood stove.

The Quick Truth

If you want the feel of a real flame but prefer push-button startup and longer unattended burn times, this stove is built for that.

It’s well suited for small to mid-sized homes, basements, or main living areas where you want controlled, thermostat-driven heat and cleaner operation than cordwood.

Key Details (What Actually Matters)

Fuel Type: Premium-grade wood pellets — Designed for high-quality pellets for cleaner burning and reliable performance.
Recommended Heating Area: 500–2,000 sq ft — Actual coverage depends on insulation, layout, ceiling height, and climate.
Maximum Heat Input: 39,260 BTU/h — The highest level of fuel energy it can produce at maximum feed rate.
Heat Output Range: 6,648 to 28,540 BTU/h — Reflects the adjustable heat levels depending on burn rate and thermostat demand.
Hopper Capacity: 60 lbs — Holds a full bag of pellets, reducing how often you need to refill.
Maximum Burn Time: Up to 51 hours — On low settings, a full hopper can run for over two days before refilling.
Burn Rate: 1.2–4.7 lbs per hour — Lower feed rates extend burn time; higher feed rates produce more heat.
Efficiency: 70.3% (HHV) / 75.8% (LHV) — A large portion of pellet energy is converted into usable room heat.
Optimum Efficiency: 78.4% — Best-case efficiency at a specific tested burn rate.
Emissions: 0.96 g/hr — Very low particulate emissions, meaning cleaner air output compared to older solid-fuel appliances.
Combustion System: Top-feed system — Pellets drop from above into the burn pot, helping maintain a steady flame.
Electronic Igniter: Yes — Allows automatic startup without manual lighting.
Electrical Consumption:
Ignition cycle: 312 watts
Continuous operation: approximately 140 watts — Requires standard 120V household power.
Noise Level: 47–60 dBa at 6 ft — Comparable to normal conversation to light background noise.
Flue Outlet Diameter: 3" — Uses listed pellet vent (Type L) venting systems.
