The Harman Pellet Pro 38 Plus Pellet Stove

The Harman Pellet Pro 38 Plus is the least expensive of the Harman range of pellet stoves. Originally introduced in 1991, but undergoing a few changes since then, this stove is simple in design and has worn well.

It's a step top design with a flat viewing window. There is an option to add a hopper extension to increase capacity from 50 lbs. to 100 lbs. Giving a maximum burn time of 40 or 80 hours.

In normal operation, this stove produces 38,000 btu. but it can be turned to turbo mode either manually or by the optional thermostat to give 43,000 btu. An exhaust temperature sensor prevents over-firing.

It has to be said that this stove has no automatic ignition. See comments below

Ashes are automatically pushed into the large ash pan by incoming unburned pellets. The ash pan has an integral handle and only has to be emptied after burning a ton of fuel.

The blower is contained within the stove in an air cooled housing which contributes greatly to quietness of operation.

Compared with many other pellet stoves, maintenance on the Harman Pellet Pro 38 Plus is ridiculously easy. See below for details.
