Oil burning technology
The heart of our oil stove is the highly efficient burner that optimizes combustion of #1 fuel oil, #2 fuel oil or kerosene.
Easy and consistent heat
This tried and true oil stove is simple to use and will heat reliably even if the power goes out.
This tried and true burner optimizes the mix of preheated combustion air and the oil resulting in an excellent combustion, with a high and consistent efficiency.
Adjust the heat with the simple control knob at the upper back corner of the stove.
The catalyzer increases the temperature of the gases within the stove to encourage complete combustion of the oil. It glows bright orange, letting you know your stove is burning cleanly and efficiently.
