Many people do not realise that smoke is wasted heat that costs money. If the gases from the fire go up the chimney instead of being burnt, there is less heat available to heat your house. You can minimise the amount of smoke from a wood heater if you:
- Burn only dry, seasoned, untreated wood
- Use smaller logs instead of only one large log
- Do not pack the fire box too full as this will starve the fire of oxygen and cause it to smoulder
- Keep the fire burning brightly for the first 20 minutes after lighting and reloading – the stronger you can get the fire going the less smoke there will be
- Always have a visible flame if you plan to keep the fire going overnight
If you are buying a new wood heater, make sure you buy one that conforms to the Australian Standard ‘AS 4013’. Wood heaters are also rated for their efficiency so one that is 65% efficient will burn less wood for the same amount of heat than one that is only 60% efficient. Check the label or see your Total Leisure staff in store. You will also be better off if you choose one that is the right size for your house. If you buy a heater that can produce more heat than your house needs, you will have to set it to burn slowly. A big heater burning slowly makes more smoke than a smaller heater burning more quickly.
Changes in technology and better wood heater design now mean that many heaters are rated to burn with much lower levels of emissions than required by the Australian Standard. Consider purchasing a wood heater with the lowest level of emissions possible.
Lopi Wood Heaters with secondary burn technology use the principles above to re-burn the gasses and smoke to continually heat the fire and increase inefficiencies.
