Why is there no fan?
The heaters work by natural convection; cold air is drawn into the heater through channels on both sides. As the cold air is heated, warm air is vented from the top of the heater, creating a gentle circulation throughout the house. As warm air cools it returns to the heater, and within a short time the returning air will get warmer and warmer, allowing the heater to operate with less fuel. Ideally this cycle should not be broken by losing warm air through ceiling vents and cold air being able to enter the house via gaps under doors. On top of natural convection our heaters also produce radiant heat. This heat is often called the “healthy heat”, similar to Sun heat where 18 degrees seems more like 23 degrees. The more heatbank you have in your fireplace, the more radiant heat will be produced. In the past, fan forced radiant heaters were necessary to cope with leaky houses. Now that we are adding insulation to existing homes, and building new homes with fantastic insulation, natural convection is the most efficient wood heating system.
How much less wood can I expect to use?
With correct operation and wood size, you should be using around 60% less wood when compared to a traditional fan forced wood heater. This is due to many elements of the design, including the use of natural convection, vermiculite linings, primary and secondary air inlets and Heatbank technology.
What is the right size wood?
Length: 300mm for a standard Euro Fireplace to around 500mm for larger fireboxes (the Milano line requires a shorter log of 250mm). Thickness: The diameter is important as smaller logs with the correct air setting will burn hotter, cleaner, and longer. To get the best out of your heater, use logs that are 100-120mm in diameter. Bigger logs need more primary air to combust which is counterproductive as this would result in heat being lost through the flue. Well seasoned wood is important as green wood will not produce heat, and will release corrosive fumes into the firebox. Red gum should be seasoned for at least 2 years.
How much flue is needed?
Due to the high efficiency of a Euro Fireplace, our heaters in general require 4m from the top of the heater.
Where are the heaters made?
Euro Fireplaces are made by leading German and Austrian heater manufacturers Thorma and Haas+Sohn, both established over 100 years ago. In Australia the heaters are sold under the Euro Fireplaces umbrella standing for high quality, high efficiency and low emissions. The factories for these Manufacturers are in Slovakia and Czech Republic, Germany and Austria.
What is the warranty?
Euro Fireplaces have a standard European manufacturers warranty of 2 years. This is extended by Euro Fireplaces with an extra 2 years of conditional warranty. With correct operation and installation very little can go wrong with these heaters.
Do Euro Fireplaces heaters work for every house?
In general yes, however if you have a less insulated leaky house, the heater will need more energy (firewood) than it would with better insulation, but still less than a conventional fan forced heater. For non-insulated spaces (sheds and/or alfresco areas), a radiant or fan forced heater may be more effective.
What is Heatbank?
Heatbank is a dense material that stores thermal energy (heat) and releases it slowly, even after the heat source (fire) is no longer producing heat. Heatbank can be added to most Euro Fireplaces in the form of refractory concrete or Magnesite, sitting between the inner and outer wall of the heater, or it can be in the form of naturally heat absorbing soapstone or sandstone, or ceramic tiles. More heatbank will result in longer burn times, more radiant heat as well as even lower wood usage.
Does the flue and installation differ to traditional wood heaters?
The flue and installation is standard Australian. Euro fireplaces prefer a single heat shield instead of a perforated second flue. The single heat shield is designed to reflect heat from the flue back into the room instead of channeling heat into the ceiling via a perforated flue. The only difference between installing a Euro Fireplace and any other fireplace, is the length of the flue (4m for a Euro vs 3.6m for another brand).
Do they burn overnight?
Yes. But not in the way that most people are familiar with. Shutting the heater down for long periods of time, blackening the glass and building up creosote in the flue, is not only dangerous, it is also no longer an acceptable practice as it severely increases emissions. Most Euro Fireplaces can retain coals between 6 to 8 hours depending on the heatbank of the particular model. The correct overnight air setting is important. Depending on density and the size of the log, more or less air is required. The right air setting allows the heater to just have enough airflow to keep the log gently burning for many hours, at the same time retaining a clean glass. Heatbank will help this process, as not only is the stored heat slowly released over a long period of time, but the heatbank also protects the firebox keeping coals hot for longer.
Does the glass stay clean?
With correct operation the glass should always stay clean. A continuously dirty glass indicates a problem either with installation, firewood quality/ size, or operation (please note, the glass will get dusty on the inside but should not turn black or brown).
What is Vermiculite?
Vermiculite is a naturally occurring, heat reflective mineral that is compressed into panels, which are used in place of firebricks. It insulates and protects the metal firebox from the heat created by the fire, and the baffle (top plate) stops heat being lost through the flue. The Vermiculite lining in the combustion chamber also reflects the heat produced by burning wood back into the fire, bringing the firebox temperature to drastically higher levels, allowing for highly efficient combustion and very clean burning. Because the firebox is fully lined with Vermiculite, the radiant heat through the glass door is very strong and can be felt within minutes of lighting the fire. This push of heat onto the glass (combined with good burning practices and the secondary air inlet) contributes to the glass staying clean.
What is the steel thickness of the heaters?
Depending on the section of the heater, the steel thickness varies from 4mm upwards. The thickness of the steel is optimized for use with vermiculite to ensure a quick heat release after starting the fire. Thicker steel or cast iron does result in slower and less efficient transfer of heat from the firebox to the air.
Who can install the heaters?
The requirements vary from state to state so if in doubt, contact your states building authority. For the most part, any plumber who holds a mechanical services license for solid fuel heaters, or licensed flue installer, can install a Euro fireplace. Be sure to ask your installer for a certificate of compliance for the installation (you will need this for your extended warranty and for insurance purposes).
