What are the benefits to heating with pellets rather than gas/oil/electric heat?

There are several benefits of heating with pellets instead of other fuel types such as gas or oil. Pellets are clean burning, renewable, affordable, and available in most geographic locations. Pellets also give the smell and ambience of burning wood without the cutting, stacking, and splitting of cordwood, making pellets a more convenient option for homeowners.

What are wood pellets made of?

The pellets used to heat your home are most commonly made from a variety of woods and wood byproducts such as sawdust. These materials are compiled and compacted waste from industries such as lumber milling, wood construction, and sawmills. As a recycled product, pellets are an environmentally friendly energy source for your home.

What is the best way to store wood pellets?

To ensure that your wood pellets remain intact and in good burning condition, store them in a cool and dry place, protected from weather and high humidity. In most cases, it is best to store your wood pellets indoors rather than outside.

Do wood pellets go bad?

If kept in a cool, dry place away from moisture and humidity your wood pellets should not go bad. If they are improperly stored, or have been exposed to water, they can deteriorate and fall apart. Proper storage ensures that your pellets will last, should you have excess at the end of the season.

How do I know which pellet appliance is right for my home?

If you are trying to decide on a hearth product, there are several things to consider. First, you need to measure the area of the space you are trying to heat. This will help you determine the size of the appliance you need to get the job done. Secondly, you need to look into what venting options are available to you in your current space.

For more in-depth insight into choosing the perfect pellet appliance for your home, contact your local authorized Harman dealer today.

Can I hook up a thermostat to my pellet appliance? Where should I place the thermostat?

The answer to this question is dependent on the specific pellet stove model you have in your home. For product specific instructions on how to connect your thermostat to your pellet stove, refer to your owner’s manual. If you don’t have your owner’s manual on hand, visit our install and owners manual page.

Once you have determined that you can connect your pellet stove with your thermostat, you then want to place your thermostat on an interior wall about 5 feet from the floor. Ensure that you do not place your thermostat in the direct heat path of your stove, or near any windows.

Is my pellet appliance EPA certified?

In a word, yes! All current Harman pellet appliances are EPA certified. To see a list of all EPA certified pellet stoves, visit the United States Environmental Protection Agency website, found here.

If your appliance still does not shut down long after operation, contact your local Harman dealer. Do not unplug your appliance if this problem persists. Unplugging your stove can damage the appliance’s electrical components.

Why is my pellet stove so loud?

If your pellet stove is making a roaring sound during operation, you may have a problem with the balance of air and fuel inside your appliance.

Why won’t my pellet stove feed pellets?

If your Harman Stove has stopped feeding pellets, there could be a few simple solutions:

  • The front door, ash pan door or hopper lid may not be closed properly. Check each for proper seal and closure. Harman products have a safety called a pressure switch that shuts the motors off if the doors are not properly closed.
  • The hopper may be empty. Fill the hopper and allow a few minutes for the unit to auger the pellets onto the burn pot.
  • Venting may be blocked. The Pressure Switch senses a lack of air flow and will shut the motors off.
  • Feed motor may have failed. Call your local Harman dealer to properly identify.
  • If there is fuel in the hopper, there may be a restriction in the hopper or feeder. Shut down and unplug stove. After it is cool, remove all fuel and examine. Clear obstruction, if found.

If these solutions do not solve your issue, there may be a specific problem that can be easily identified by your local Harman dealer.
