After building stoves for over 30 years, we think we know what our
customers are looking for. The beauty of cast iron. The convenience of
pellets. The power of 50,000 BTUs. And our quietest pellet stove ever.
The Harman XXV pellet stove was designed for our 25th Anniversary
and is created with everything you expect in a Harman…automatic
ignition, venting choices, automatic temperature control, a large ash
pan that’s easy to get to, and the convenience of super easy cleaning.
The XXV symbolizes everything Harman stands for. Quality. Beauty.
Functionality. The XXV. Our finest creation yet.

The XXV does not use a thermostat like
other pellet stoves. Rather it uses a tiny
sensing probe that sends information to the
microprocessor on the stove. This information
is used to feed the proper amount of fuel at the

desired rather than the room temperature.
Automatic Temperature Control
The XXV’s automatic temperature control system eliminates the warm/cold
cycle associated with thermostatically controlled heating systems and even
turns the XXV on and off as needed.
Patented Feeder & Burn Pot
The XXV bottom feeder system precisely meters pellet fuel into our patented
burn pot which can burn all grades of pellet fuel. In addition, the XXV’s burn
pot allows fuel to be burned at a very low rate.
Exclusive Ignition System
The XXV draws in air across a specially designed heating element located
in the bottom of the burn pot. The air is then heated to the point where it
ignites the pellets as they enter the burn pot.
Accordion Heat Exchanger
The XXV’s accordion heat exchanger allows a large amount of surface area to
be placed in a small area, greatly increasing heat transfer efficiency.
Direct Vent
Harman Pellet Stoves are the only 100% true direct vent pellet stoves available. By using the optional outside air kit, the stove can be set up to use 100%
outside air (not room air). Thus allowing the stove to be installed closer to the
door and window openings than other brands. This versatility allows the stove
to be placed where it best fits the layout of the room while also saving the
cost of additional venting.
Temp erature Contr ol
The XXV has a remarkably precise temperature
control system built right in so you won’t need
an old-fashioned thermostat. The Harman XXV
constantly monitors room temperatures and
makes automatic adjustments to the pellet feed
rate and combustion air so you get very even
heating. It even turns off and on as needed.
Your home is kept warm and comfortable
without the rapid fluctuations in temperatures
common to other pellet stoves. The XXV is so
advanced it will keep the room temperature
just where you want it, regardless of the quality
of pellets you burn or the frequency you clean
your stove.
Top Vent Adapter
The XXV is the first Harman Pellet Stove to have the option of top venting.
This unique venting configuration uses a 6" stove pipe which is conventionally
used on most wood stoves. Therefore, a wood stove can be replaced with the
XXV Pellet Stove, maintaining the look of a traditional cast iron wood stove
with the ease of pellet fuel.

The XXV Advantage
The XXV will burn any grade of pellet at maximum efficiency and still
keep your home at your desired temperature.
Harman’s patented feeder and burn pot work with the ESP Control for
state-of-the-art operation and efficiency. These features provide amazing
heat output with different fuel quality, ash content and moisture. In
other words, it improves performance, efficiency, and conserves fuel.
Keeping Safety in Mind
The XXV has several safety features that automatically monitor changes
in the stove’s temperature and draft. The XXV cannot overheat. The
