A pellet stove operates by burning small, compressed wood pellets as fuel. Pellet stoves are a combination fireplace that uses fire and circulation to produce the desired warmth. While burning wood pellets produce heat, powered fans take hot air and move it through the system – and warm up your space. Pellet stoves offer convenience and efficiency while minimizing environmental impact—perfect for those seeking sustainable heating options!

Auto-ignition stoves are easy to light with a single button. Manual ignition stoves require the user to light the wooden pellets to fire up. These pellets are made from recycled sawdust and other biomass materials, making them an eco-friendly heating option.

  1. Fuel Preparation: The compacted pellets used in pellet stoves are made by compressing dry sawdust or other types of biomass into small cylindrical shapes. They are often produced from renewable sources like recycled wood products.
  2. Fuel Delivery: The stove’s hopper holds the supply of pellets, which are automatically fed into the combustion chamber by a drill or screw mechanism. This ensures a consistent and efficient burn.
  3. Ignition: Once in the combustion chamber, an igniter is activated to light the pellets. The flame then spreads throughout the chamber, producing heat.
  4. Combustion Process: Inside the stove, air is introduced to support combustion while exhaust gases are expelled through a vent pipe connected to a chimney or exterior wall.
  5. Temperature Control: Most pellet stoves have thermostat controls or adjustable knobs to maintain optimal temperature levels in your space. These allow you to easily regulate how much fuel is burned and control indoor temperatures accordingly.
  6. Exhaust Venting: As with any burning appliance, a stove produces exhaust gases that must be safely removed from your home through venting pipes or chimney flues.
  7. Heat Distribution: The heated air is pushed out using built-in fans and dispersed evenly throughout the room via adjustable vents.
