Transforming an Inefficient Open Fireplace with the Tara Eco Fireplace
A beautiful open fireplace can add character to a room, but it is not usually an efficient way to heat a home. Much of the heat produced by the fire escapes directly through the chimney, rather than warming the surrounding space. Retrofitting an existing open fireplace with a closed cast-iron stove can significantly improve its heating performance. For this installation in Sandton, Gauteng, the Tara Eco Multifuel Fireplace provided the ideal upgrade, combining up to 80.5% efficiency with an impressive 8kW heat output.
Quick read: Is it worth replacing an open fireplace?
Yes. Replacing an open fireplace with a modern cast-iron stove can provide considerably more useful heat while improving fuel efficiency and control.
The Tara Eco Multifuel Fireplace:
Produces up to 8kW of heat
Offers an efficiency rating of up to 80.5%
Weighs an impressive 135kg
Is constructed from solid cast iron
Offers top and rear flue options
Can be retrofitted into many existing fireplaces
Combines modern efficiency with traditional styling
An open fireplace may operate at only around 10% to 15% efficiency. By comparison, the Tara Eco is rated at up to 80.5%, making it approximately six to eight times more efficient, depending on the original fireplace and installation.
Why are open fireplaces inefficient?
Open fireplaces offer very little control over airflow and combustion. As the fire burns, much of the heat rises directly through the chimney before it can warm the room. The chimney can also draw already-heated air out of the home, creating draughts and allowing cooler air to enter elsewhere. As a result, an open fireplace may create a welcoming atmosphere without providing the effective room heating expected from a modern fireplace. A closed cast-iron stove controls the amount of air entering the fire more effectively. This allows the fuel to burn in a more controlled environment, helping to transfer a greater proportion of the generated heat into the room.
Upgrading an open fireplace in South Africa
For this installation in Sandton, Gauteng, the original open fireplace was an attractive architectural feature. However, its open design meant that most of the heat was being lost through the chimney. The original fireplace was removed as far as reasonably possible. A steel closure plate was then bolted securely into place to cover the remaining void, with the flue passing through it.
The plate serves two important purposes:
Firstly, it creates a neat and considered finish, allowing the Tara Eco to stand slightly proud of the original fireplace surround.
Secondly, it closes the large opening left by the former fireplace, helping to prevent valuable heat from escaping directly into the chimney void.
The result preserves the character of the existing fireplace while significantly improving its performance.
Why was the rear flue option used?
The Tara Eco offers both top and rear flue exits, providing greater flexibility when retrofitting the stove into an existing fireplace. For this installation, the rear flue exit was chosen to enhance the clean lines of both the Tara and the original fireplace surround. Routing the flue from the rear reduces visible pipework and creates a simpler, more integrated appearance.
The finished result feels considered and balanced, allowing the traditional cast-iron design of the Tara to remain the focus.
How efficient is the Tara Eco Multifuel Fireplace?
The Tara Eco Multifuel Fireplace has an efficiency rating of up to 80.5%. An open fireplace may achieve an efficiency rating of only approximately 10% to 15%, although actual performance will depend on the fireplace design, chimney, fuel and surrounding home. Based on these figures, the Tara Eco can be approximately six to eight times more efficient than an open fireplace. This means that a much greater proportion of the energy produced by the fuel is converted into useful heat for the room, rather than being lost through the chimney.
What are the benefits of a cast-iron fireplace?
Excellent heat retention - Cast iron absorbs heat while the fire is burning and continues to radiate warmth into the room.This creates a steady, comfortable source of heat and helps the room remain warmer for longer.
Greater durability - Cast iron is strong, substantial and designed to withstand repeated heating and cooling.A well-made cast-iron fireplace can provide many years of reliable use when correctly installed, operated and maintained.
More controlled heating - Unlike an open fireplace, a closed stove allows the airflow and heat output to be controlled more precisely.This makes it easier to manage the temperature of the room and avoid burning more fuel than necessary.
Improved fuel efficiency - A closed combustion chamber helps the fire burn more efficiently.More of the fuel’s energy is used to heat the room, rather than escaping through the chimney.
Timeless design - Cast-iron fireplaces have a distinctive sense of permanence and craftsmanship.The Tara Eco brings the character of a traditional fireplace into the home while incorporating the efficiency expected from a modern heating appliance.
A practical retrofit solution - A freestanding cast-iron stove can often be fitted into an existing fireplace opening.This allows homeowners to retain the original surround, mantel or architectural detailing while upgrading the working fireplace itself.
Can the Tara fit into an existing open fireplace?
The Tara Eco is an excellent retrofit option for many existing open fireplaces. However, every home and fireplace must be assessed individually.
The installation will need to consider:
The size of the existing fireplace opening
The condition and dimensions of the chimney
The most suitable flue route
The required clearances
The size and insulation of the room
Ventilation requirements
Applicable installation and safety requirements
The flue is therefore specified separately, depending on the requirements of each home. A correctly designed and installed flue is essential for the safe and efficient operation of any wood-burning or multifuel fireplace.
A more efficient fireplace without losing its character
Improving the efficiency of an open fireplace does not mean losing the character that made it beautiful in the first place.For this Sandton installation, the original fireplace surround was retained and used to frame the new Tara Eco. The steel closure plate and rear flue created a clean, integrated finish while helping to reduce unnecessary heat loss. The completed fireplace still offers the warmth and atmosphere associated with a traditional fire, but with far more effective room heating and considerably greater efficiency. For South African homeowners looking to upgrade an existing open fireplace, the Tara Eco offers an elegant balance of heritage styling, durable cast-iron construction and modern performance.
