Freedom Stoves Independence PS21 Pellet Stove review

A stove built for power outages: a 24V system that runs on two 12V batteries, sold separately, for over 40 hours.

What the listing commits to

Freedom Stoves states up to 34,700 BTU for 800 to 1,800 square feet, a 24V DC system, Wi-Fi, a touchscreen, a remote and a 5-year limited warranty.

The feature that sets it apart

A pellet stove normally needs mains power. This one runs on two 12V batteries for over 40 hours, according to the listing, and the Amazon page also describes it as engineered for do-it-yourselfers.

Add the cost

Two deep-cycle batteries and a way to charge them are extra, so budget for those at the start.

Before you buy

Check the vent size in the manual before ordering pipe, and buy pellets by the grade the manual names.
