The Warmer Cheaper website also includes information about the pros and cons of different types of firewood. Drying time varies significantly between woods, so while plantation pine and Douglas fir will be dry and ready to burn after 1-2 years, macrocarpa needs 3-5 years of drying time before it will burn cleanly, and blue gum needs 5-6 years.
Avoiding wet wood
Sometimes what seems like a good deal on firewood from a roadside wood seller can turn out to be a bad investment, as the wood may not have been ‘seasoned’ (dried out) for long enough to burn efficiently.
You can test your firewood’s moisture content yourself using a moisture meter available from home improvement shops.
Plantation pine and Douglas fir are quicker-drying woods. We generally don’t recommend using old man pine, as its high resin content means it produces a lot of smoke
If you want help testing the moisture content of your wood, give us a call on 0800 324 636.
Better burning techniques
Most of us have been taught to put big logs on the bottom of the wood burner, then smaller logs, then kindling, and then paper on top. A more efficient alternative is the upside-down fire-building method, which burns for longer without needing to be topped up. Videos and a step-by-step guide to the upside-down fire technique are available on the Warmer Cheaper website.
A modern, well-maintained wood burner and clean chimney
It’s important to keep your burner in good condition so it can burn as efficiently as possible. If smoke is coming into the room or you notice your wood burner isn’t burning as hot as usual, it’s probably time to check your burner and/or get your chimney swept. Our handy burner maintenance checklist will help you through the process.
