Specialising in Australian designed and built combustion wood heaters.
Pellet Fires Tasmania specialises in Australian made wood heaters.
In 2016, around 75% of wood heaters sold in Australia were imported. Pellet Fires Tas sells high quality Australian made wood heaters made in Australia by Australian owned business. Today there are la lot of cheap and not so cheap imports to choose from. We believe that while there remains high quality, good value for money Australian made products we should support these companies first. Aranbe and Eureka are our preferred wood heater suppliers.
CONSIDER YOUR HEATING NEEDS
Output of heat is rated in kilowatts (kW). The amount of kilowatts you need will depend on where you are in Australia, the size of your home, how many windows there are, and if you have home insulation. For example, an 180 square meter house that is well insulated will require a lower output than the same sized home with no insulation. Heaters should be sized to accommodate average, rather than extreme, temperatures.
CHOOSING A WOOD HEATER: SAFETY COMES FIRST
Ensure your choice of wood heater has been manufactured to all the rigorous Australian Standards applicable to wood heaters. All wood heaters manufactured since 1992 must adhere to AS/NZS 4013 – the Australian Standard for emissions ensuring they are clean burning and environmentally responsible.
Wood heaters are available in a wide range of models that vary in output from small units intended to heat a single room, to very large units with the capacity to heat relatively large houses. The final selection will depend upon a number of factors: e.g. house design, insulation levels and the length of time the heater is to be operated. Larger heaters are best suited to homes with an open plan design where heat can be readily and effectively circulated to other areas of the home. Most new wood heaters for sale in Australia are tested to determine their output, energy efficiency and particle emissions levels under Australian/New Zealand Standards AS/NZS4012 and AS/NZS4013.
WHAT DOES CLEAN BURNING MEAN?
Clean burning wood heaters slow down the exit of smoke through a secondary combustion process. This process generates more heat from each log and reduces the amount of smoke and particles going up the flue and into the environment. New wood heaters with clean burn systems greatly reduce CO2 emissions and require less fuel, gaining more energy out of the wood. While old open fireplaces lose as much as 80% of their heat via the chimney, clean burn systems lose around 15%.
Wood heaters provide heat in one or a combination of the following ways:
(A) Radiation (Radiant Heat)
(C) Fan Forced Air Distribution
There are no clear performance differences between cast iron or plate steel construction, a painted or enamelled finish, however, there are important differences in heat delivery. The main ways are by direct radiation, convection or a combination of both.
FREESTANDING RADIANT WOOD HEATERS
Radiant wood heaters transfer about two-thirds of their heat output by radiation and about one-third by convection. They have very hot surface temperatures and heat by sending their heat out in all directions. The surface of objects such as walls, floors, ceilings, furniture and people that face the wood heater, are warmed directly by the radiated heat. Radiant wood heaters warm quickly so if you sit close to them you can feel the heat even if the whole room hasn’t yet warmed up. However, they have uneven heat distribution i.e. it is warmer closer to the heater and cooler further away.
FREESTANDING CONVECTION HEATERS
Convection wood heaters have a ventilated casing around the firebox which is either tiled or fabricated from metal. Heat is distributed by convective currents, with cooler air being drawn in to rise between the firebox and the outer casing, keeping the outside of the unit relatively cool. Convection heaters transfer about two-thirds of their heat output by convection and about one third by radiation. Sometimes electric fans may be built in to increase the convective air flow. Because warm air rises, these heaters tend to heat the room from the ceiling down, and as a result it takes longer for the warmth to be felt. Reversible ceiling fans can help overcome this. Convection wood heaters generally provide a fairly even heat throughout a room and because their exterior surfaces are lower in temperature than radiant models, they are less likely to cause burns from direct contact. A fireguard is still recommended. Convection wood heaters generally provide even heat throughout a room.
A fireplace insert is a wood heater specifically designed for installation within a masonry fireplace. Inserts are commonly used to convert open brick fireplaces, which are usually unable to produce sufficient heat. This type of conversion ensures that most of the heat is delivered to the room instead of being trapped in the masonry structure, or wasted via the chimney. Older installations allowed the emissions to exit directly into the chimney cavity. AS/NZS 2918 now requires a stainless steel flue be installed from the flue collar of the appliance to the top top the chimney greatly improving performance. The evolution of fireplace insert designs together with improved installation has enhanced performance to the extent that today’s fireplace inserts are almost as efficient as freestanding wood heater.
OPEN FIRE PLACE INSERT
Another type of insert commonly known as a heat circulating fireplace can also be installed into an open masonry chimney and will provide a greatly improved performance and efficiency when compared to an open fireplace. They do not however, provide the same combustion efficiency as freestanding and fireplace inserts. This type of heater cannot provide an ‘overnight burn’ as it has an open (unsealed) front.
