The Harman Advance Pellet Stove

The Harman Advance freestanding pellet stove has a glass hopper lid so it's possible to glance in and check out the fuel situation. Producing 48,000 btu. and rated to heat 1,500 square feet, this stove has a rear firewall accordion heat exchanger as well as the normal top exchanger.

This unit has a large bay window, affording good fire views. The brick effect fireback is a standard fitting on this stove.

The ash pan won't need emptying until a ton of pellets have been burned. Access is easy.

The Harman Advance is a slim stove, only twenty and a half inches deep.

For most heat settings other than maximum, the stove is capable of running without its distribution blower being turned on. This means that you can have a quiet time with a view of a good fire.

The control board has some diagnostics to help isolate any problems. There is also a port where a Harman dealer can plug in a diagnostic tool.

The Harman room heat sensor is 'intelligent' in that it can monitor temperature trends in the room and either speed up or slow down the stove to compensate. This provides more even temperatures than a stove which starts and stops.
