BETTER BURNING WOOD// Is your wood good?
Too often our workers come across problems created by bad wood! Moisture Content should be at or below 25% and if it's not being sold by weight, you're not getting an accurate or fair rate!
Have a look at the wood guide for more information.
CREOSOTE // The hidden fire hazard! It's why we sweep!
Burning wood and fossil fuels at low temperature causes incomplete combustion of the oils in the wood, which are off-gassed as volatiles in the smoke. As the smoke rises through the chimney it cools, causing water, carbon, and volatiles to condense on the interior surfaces of the chimney flue. The black oily residue that builds up is referred to as creosote, which is similar in composition to the commercial products by the same name, but with a higher content of carbon black.
Over the course of a season creosote deposits can become several inches thick. This creates a compounding problem, because the creosote deposits reduce the draft (airflow through the chimney) which increases the probability that the wood fire is not getting enough air to burn at high temperature. Since creosote is highly combustible, a thick accumulation creates a fire hazard. If a hot fire is built in the stove or fireplace, and the air control left wide open, this may allow hot oxygen into the chimney where it comes in contact with the creosote which then ignites—causing a chimney fire. Chimney fires often spread to the main building because the chimney gets so hot that it ignites any combustible material in direct contact with it, such as wood. The fire can also spread to the main building from sparks emitting from the chimney and landing on combustible roof surfaces. In order to properly maintain chimneys and heaters that burn wood or carbon-based fuels, the creosote buildup must be removed.

AUS NZ Standards // Efficiency and safety!
There are many standards that must be met, with these standards continuously changing and evolving. If your fireplace is more than 10 years old, you're likely no longer complying with these standards. However this isn't a large problem as inhibits your ability to legally re-install or sell such a fireplace. Today's fireplaces are cleaner burning, this meaning less harmful emissions, and less damage to our neighbours and the environment.
