Open vs Closed Fireplaces: A Comprehensive Guide for Australian Homeowners

There’s nothing quite like gathering around a crackling fire on a chilly evening. But when choosing between open and closed fireplaces, the decision isn’t just about aesthetics. It’s also about efficiency, safety, environmental impact, and long-term value.

In this guide, we’ll explore every facet of this debate, helping you make an informed choice that suits your lifestyle, budget, and home design.

What Sets Open and Closed Fireplaces Apart?

Open Fireplaces

According to the Australian Home Heating Association, approximately 22% of Australian homes with fireplaces still use traditional open designs, with the highest concentration in heritage homes and rural properties.

An open fireplace is what most of us envision when we think of a traditional fireplace; an open hearth where wood burns, with smoke escaping up the chimney. These fireplaces offer an authentic experience with unobstructed views of the flames.

Open fireplaces include:

• Traditional masonry fireplaces built with brick, stone, or concrete
• Open hearths that often feature decorative surrounds
• Rumford fireplaces (taller, shallower designs that reflect more heat)
• Some decorative fireplace designs that prioritise aesthetics over heating

Closed Fireplaces

Closed fireplaces, on the other hand, feature a sealed combustion chamber, typically with a glass door or panel that separates the fire from your living space. These include:

• Slow combustion wood heaters with adjustable air controls
• Wood-burning stoves (freestanding or built-in)
• Enclosed fireplace inserts that retrofit into existing fireplaces
• Gas fireplace units with sealed glass fronts
• Pellet stoves that automatically feed fuel for consistent heating

Modern closed systems often incorporate Australian design innovations specifically created for our climate conditions, including enhanced thermal properties for our milder winters and bushfire safety features for high-risk areas.

Now that we understand the basic distinction, let’s dive deeper into how these two options compare across various important factors.

Heating Efficiency

Heat Output Comparisons

A slow-combustion fireplace converts over twice the energy from wood into usable heat compared to open designs. For example, burning 5kg of wood in a closed system can heat a medium-sized living area for 6-8 hours, while an open fireplace might require 15kg for similar results. This disparity arises from:

• Combustion control: Adjustable vents in closed units regulate burn rate
• Thermal mass: Cast iron or steel construction stores and radiates heat
• Chimney design: Insulated flues minimise heat escape

Real-World Impact on Comfort

Closed systems maintain consistent temperatures, eliminating the “hot face, cold back” effect common with open fires. For whole-home heating, inserts with heat-circulating panels outperform traditional open hearths, which primarily warm their immediate vicinity.

Safety First

Spark and Ember Risks

Open fireplaces require vigilant supervision as sparks can jump 1-2 metres from the hearth. In contrast, closed units feature sealed glass doors and spark screens, reducing fire hazards—a crucial factor for households with children or pets.

Air Quality Considerations

Wood smoke contains fine particulate matter (PM2.5) and carbon monoxide, with open fires emitting up to 5x more pollutants than certified closed systems. NSW regulations now restrict open fireplace use during winter inversions, reflecting their environmental impact. Closed combustion’s secondary burn technology reburns smoke particles, slashing emissions by 60-80%

Environmental Impact

Emission Profiles

Closed fireplaces’ controlled burns produce:

• 80% less particulate matter
• 70% reduced carbon monoxide
• 50% lower volatile organic compounds (VOCs)
  compared to open counterparts. These figures meet the National Environment Protection Measure for Air Quality, making them compliant with tightening state regulations.

Sustainable Fuel Use

While both systems require seasoned hardwood, closed units’ efficiency means:

• 3x less wood consumed annually
• Reduced deforestation pressure
• Lower carbon footprint per BTU of heat

Operational Savings

Closed systems save $600-$1,200 annually in fuel costs.  Over a 10-year lifespan:

• Open fireplace: $36,000 (fuel) + $2,000 (maintenance) = $38,000
• Closed unit: $12,000 (fuel) + $1,500 (maintenance) = $13,500

The Atmospheric Factor

While closed units dominate in efficiency, open fires retain an irreplaceable sensory experience.

Making the Right Choice: Key Decision Factors

When deciding between open and closed fireplaces, consider these key factors:

• Climate and heating needs: In colder Australian regions like Tasmania, the Victorian highlands, and the Snowy Mountains, the efficiency of closed systems becomes even more valuable. For warmer areas like coastal NSW or Queensland, where fireplaces might be used more for ambiance than primary heating, open designs might suffice.

• Home Design: Contemporary homes often benefit from the clean lines of modern closed fireplaces, while heritage homes might call for traditional styling (though inserts can provide efficiency without sacrificing character). Consider how the fireplace will integrate with your home’s existing architecture and interior design.

• Environmental values: If sustainability is important to you, closed systems clearly have the advantage. This is particularly relevant in urban areas with air quality concerns and bushfire-prone regions where responsible burning practices are essential.

• Budget considerations: Think long-term about fuel costs, not just installation. With Australian firewood prices ranging from $350-$500 per tonne depending on your location, efficiency directly impacts your ongoing expenses.

• Local regulations: Check with your local council about any restrictions on fireplace installations or wood burning in your area. Some Australian municipalities have implemented strict controls on new fireplace installations, particularly open systems.

• Lifestyle factors: Consider how you’ll use the fireplace—is it primarily for atmosphere during occasional gatherings, or will you rely on it for regular heating? Your usage patterns should influence your choice.

• Property value impact: Real estate agents report that efficient heating systems can increase property values by 3-5% in cooler Australian climates, with closed systems generally preferred by prospective buyers.
