Have you noticed that your outdoor wood boiler is burning too fast? An outdoor wood boiler is designed to slow down the burning process to produce the most amount of heat from each piece of wood. In some situations, an outdoor wood boiler burns through the woodpile too quickly to be effective. There are various factors that cause high wood consumption. Read on to find out why your outdoor wood boiler is burning so fast.

Unseasoned Wood

A common reason for burning too fast is the use of wood that has not been seasoned. If your wood lacks seasoning, there is moisture trapped in the wood, and up to 40 percent of your woodpile is burned to remove the moisture. This means you lose 40 percent of your wood’s heating value which is a waste. The higher the moisture content, the more wood is needed to burn. It would be less efficient to burn unseasoned wood, especially when it creates more smoke and the build-up of dangerous substances.

Poor Ash Maintenance

If your outdoor wood boiler has a heavy buildup of ash, it reduces the efficiency of burning wood. A thick layer of ash in the wood boiler may absorb moisture from the wood and form a substance that will damage the inner steel layer. Having a layer of ash helps to start the fire quickly, but too much can lead to the poor burning of wood. Do not allow your ash to rise to pass the bottom door frame. Instead, keep it around one inch high at the bottom of the firebox. Remember to conduct a monthly clean-up of the firebox, which includes removing all ashes. Ensure that your boiler is consistently well maintained for the proper function of your outdoor wood boiler.

Low Operating Temperature

A wood boiler should not operate at a temperature below 140 degrees. This is because, at such low temperatures, the moisture from wood condenses on the inner walls of the boiler. It causes creosote to form, a compound from the burning and distillation of wood that blocks the airflow in the tubes of a boiler. When it occurs, heat is trapped in the wood boiler. Regardless of the quality of the wood used, the wood cannot burn efficiently because air is unable to flow past the wood boiler tubes.

How to Optimize Burning in an Outdoor Wood Boiler

Using seasoned wood, keeping the ash levels low, and using high operating temperatures are some things to incorporate so that you can have the best chance of burning wood at an optimal pace. Always read your manuals or consult with the company you have purchased from to understand how to maintain and properly use the boiler.
