The Kozi Shop Heater KSH 120 Pellet Stove

The Kozi Shop Heater is a furnace style box, (See Pellet Furnaces), with a choice of a large or small viewing window. It produces 40,000 btu. and is capable of heating an area of 1,800 square feet. Maximum burn time is from 100 hours to 230 hours with extensions.

This stove is very similar to the Pelpro Home/Shop heater, (See Pelpro), with a slightly lower btu. input. On the other hand, the overall efficiency of the Kozi stove, at 86%, is greater so the stoves are roughly comparable.

Based on the Kozi 100, The hopper capacities of the Kozi Shop Heater allow very log burn times between fuel fills. Extra venting at the top keeps the hopper cool and enables the body of the stove itself to be used as part of the heat exchange system.

Standard equipment with this stove is the glass saver, (DX large glass model only), which reduces cleaning, and the spring coil cool grip door handle.

The 'MX' controller provides stove diagnostics in the form of blinking led lights to alert the user to any problems.
