When temperatures drop, heat pellets offer a clean, efficient, and sustainable way to keep homes warm. Whether you rely on a pellet stove for your primary heat source or as a supplement, understanding how pellets work, and how to store them, can make a big difference in performance and comfort.
At The Mill, we supply premium hardwood and blended wood pellets from trusted brands to help customers across the Mid-Atlantic stay warm through every cold snap. Here’s what you should know before firing up your pellet stove this winter.
What Are Heat Pellets?
Heat pellets are made from compressed sawdust, wood chips, and other byproducts of the lumber industry. No binders or chemicals are added—the natural lignin in the wood holds each pellet together when compressed under heat and pressure.
This process creates a dense, uniform fuel source that burns efficiently and produces consistent heat output. Pellets are also a renewable energy source, making them a popular choice for homeowners who want to reduce their environmental footprint.
The Benefits of Heating with Pellets
-
High efficiency: Pellets burn hotter and more consistently than cordwood, with efficiency ratings often above 80%.
-
Convenient packaging: Sold in easy-to-handle 40-lb. bags or full pallets for bulk users.
-
Low ash content: Premium pellets leave minimal residue, meaning less stove maintenance.
-
Clean energy: Produced from renewable wood waste, pellets generate fewer emissions than fossil fuels.
Understanding BTUs and Pellet Quality
Pellet quality can vary by manufacturer, and not all pellets burn the same. When choosing fuel, look at the BTU rating (British Thermal Units) and ash content listed on the bag.
-
Higher BTUs = more heat output per pound.
-
Lower ash = cleaner burn and less maintenance.
At The Mill, we carry top-tier brands known for consistent performance, ensuring your stove runs efficiently all season long.
Pellet Stove Basics
Pellet stoves operate by feeding pellets automatically from a hopper into a burn pot, maintaining a steady flame with minimal effort. They require electricity to run the auger and fan systems, so a small backup power source is recommended during outages.
For best results, follow the manufacturer’s cleaning schedule and use only premium pellets designed for residential heating. Cheap or damp pellets can cause clogs, smoke, and reduced heat output.
Proper Storage: Protecting Your Investment
Pellets are highly absorbent. Exposure to moisture can cause them to swell, break apart, and lose efficiency. Storing them properly is key to maintaining burn quality.
Indoor Storage (Best Option)
-
Store in a dry, enclosed area such as a garage, basement, or shed.
-
Keep bags off the ground on a pallet or shelf.
-
Avoid areas prone to humidity or flooding.
Outdoor Storage (If Space Is Limited)
-
Choose a raised, level spot where water won’t pool.
-
Keep the original shrink-wrap or plastic shroud intact; seal any tears with waterproof tape.
-
Cover with a heavy-duty tarp anchored tightly with weights.
-
Create a small peak under the tarp so rain or snow can roll off instead of collecting.
-
Keep the area clear of snow and ice for easy access.
These small steps can prevent moisture damage and keep your fuel performing like new.
Common Questions
How many bags of pellets do I need for winter?
The exact amount depends on your home’s size, insulation, and how warm you keep your house. Factors like stove efficiency and local climate also play a significant role, so it’s best to estimate based on your specific needs. On average, most homeowners use 2–3 tons (100–150 bags) of pellets per heating season.
Can I mix pellet brands?
Yes, but it’s best to use one type at a time. Switching frequently can change ash content and feed rate, requiring stove adjustment.
What should I do with leftover pellets in spring?
Store any extra bags indoors through the summer to prevent humidity damage. Properly stored pellets can last into the next heating season.
