The Osburn 3300 Wood Stove – The Most Effective Eco-Friendly Heating Source.
The Osburn 3300 represents the essence of eco-friendly and efficient heating. With an emission rate of 0.95 g/h, this non-catalytic wood stove is among the cleanest on the market and represents an environmentally friendly source of energy. This north-south loading model will keep your family warm all night long, even in very cold weather, thanks to its power of 90,000 BTU/h.
The design of the heater is flawless and enhanced by a set of high-density bricks, a stainless steel heat shield added to the C-Cast baffle, a new cast iron door mold, an integrated ash drawer, a top heat deflector as well as decorative side panels.
This new-generation wood stove offers a multitude of configuration options. In addition to the traditional or straight legs and the door overlay available in black or brushed silver, you can choose a pedestal, a rigid spark arrester, a blower with thermodisc, and a glass ash lip according to your needs. Let yourself be inspired and reinvent your interior comfort!
