Top brands like Harman and Quadra-Fire both provide quality pellet fireplace inserts with easy to use controls and straightforward owner’s manuals. Choosing a quality pellet insert or pellet stove as opposed to something from a big box store is the true difference maker.

Service is crucial to keeping your pellet fireplace insert operating correctly.

We like the Accentra52i pellet fireplace insert because of Harman’s dedication to quality. All pellet hearth appliances require regular maintenance. Heat, dust and electronics tend to go poorly together. Weekly cleaning and monthly deep vacuuming are mandatory to keep your pellet heating appliance working efficiently.

In our view, Harman makes the highest quality pellet stove fireplace inserts.

Harman makes this easy by considering the need for service throughout the lifecycle of their pellet fireplace inserts and pellet stoves. Many other brands do not consider the challenges of servicing their big box store pellet units. Harman’s unique burn pot technology cause less jams because the pellets rise up from the bottom of the pot as opposed to dropping in from the top.
