The Osburn 2500 pellet stove is the perfect entry-level option, offering reliable performance in a practical and accessible design. Comparable to the 3000 model, it carries a more traditional wood stove look while keeping the brand’s distinctive signature style.
Crafted from premium-quality materials, this unit combines durable Canadian steel, German-imported ceramic glass, stainless steel heat exchangers, and a resilient thermosetting powder paint finish. Despite its high-end build, it comes at a very competitive price and is even eligible for government incentives and credits.
With an ultra-low particle emissions rate of just 0.96 g/h, the Osburn 2500 already surpasses some of the most stringent upcoming environmental standards for solid fuel appliances.
Designed with simplicity in mind, it features easy installation, an intuitive electronic control system, and a user-friendly thermostat. Maintenance is hassle-free too, thanks to tool-free access to removable components for quick cleaning.
The Osburn 2500 is the ideal choice for anyone seeking comfort, performance, and efficiency—without the complexity.

(1) Values are as measured per CSA B415.1-10, except for the recommended heating area, hopper capacity, maximum burn time and maximum heat input rate. Results may vary depending on pellet quality, density, length, and diameter.
(2) Grades of pellet fuel are determined by organizations such as Pellet Fuels Institute (PFI), ENplus and CANplus.
() Recommended heating area and maximum burn time may vary subject to location in home, chimney draft, heat loss factors, climate, fuel type, feed rate, fuel level, and other variables. The recommended heated area for a given appliance is defined by the manufacturer as its capacity to maintain a minimum acceptable temperature considering that the space configuration and the presence of heat distribution systems have a significant impact in making heat circulation optimum.
(3) Based on the maximum burn-rate and a dry energy value of pellet at 8,600 BTU/lb.
(4) As measured per CSA B415.1-10 stack loss method.
(5) Efficiency based on radiated and delivered heat when allowing cycling from high to low burn to simulate thermostat demand. LHV % is based on manufacturer’s estimation.
(6) Higher Heating Value of the fuel.
(7) Lower Heating Value of the fuel.
(8) Performances based on a fuel load prescribed by the standard at 7 lb/ft³ and with a moisture content between 19% and 25%.
(9) Optimum overall efficiency at a specific burn rate (LHV).
(10) The optimum heat transfer efficiency is for the low burn rate (using HHV) and represents the appliance’s ability to convert the energy contained in the wood logs into energy transferred to the room in the form of heat and does not take into account the chemical losses during combustion.
(11) This appliance is officially tested and certified by an independent agency.
(12) Carbon monoxyde.
(13) Unless stated otherwise, measures were taken directly at the main power source and include all electrical components present in the appliance.
