Why You Should Choose a Pyro Fire
True Kiwi Innovation
The Pyro Classic Wood Fire was developed by scientists at the DSIR (New Zealand Department of Scientific & Industrial Research).
They were tasked with creating the ultimate solution for burning wood in the most economic and environmentally conscious way and so, after years of design and research, the Pyro Classic was born.
For more than 40 years, this unique kiwi fire has led the global market in efficiency.
The ‘Heat Sustainer‘
Massive Heat Storage
Designed to keep you warm long after the fire has burned down.
Weighing in at a whopping 45kg (for Pyro Classic), the Heat Sustainer is formidable thermal mass capable of absorbing and storing an abundance of heat.
This ceramic firebox stores more heat than any other conventional wood fire through a slow and even release of its heat over an extended period.
The cylindrical design enables circular encapsulation allowing for a more complete burn and extraction of fuel from your wood.
Circular encapsulation improves efficiency and is more cost effective.
VS Conventional Steel Firebox
Heat Sustainer From Pyro Fires
30mm Thick Ceramic
Ceramic not only absorbs and stores more heat than steel, it also releases it slower and more evenly. As a result, less wood is burned to maintain a warm home.
Circular encapsulated flames allow for a more complete burn and extraction of fuel from your wood.
Is indestructive to heat beyond what burning wood can achieve.
Conventional Steel Firebox
Absorbs heat rapidly, but can’t store it. Heat escapes just as quickly as it appears, using more wood to heat your home.
Flames escape to the corners leading to an incomplete burn and extraction of fuel from the wood.
Is destructible to heat. Expands and contracts as it heats up and cools down, compromising the integrity of the welded firebox over time.
Heat Sustainer Benefits
Of a Large Ceramic Fire Chamber
Reduced Heating Costs
Compared to a steel firebox, a hot ceramic chamber will burn less wood to maintain its temperature.
Burns Less Wood
Circular design for circular flame encapsulation. Provides a more complete and thorough burn.
The Heat Sustainer absorbs and stores heat which will continue to keep you warm long after the fire has burned down.
Genuine Overnight Burn
Keep toasty through the night and wake up to a warm home.
Wood is burned more thoroughly requiring less reloading, log splitting, carrying…less work in general.
A Healthier Home
Even after the fire has burned down, the Heat Sustainer will slowly and evenly release its stored heat to fight one of the leading causes of dampness – cold rooms.
….It’s a really clever design”
Heat Sustainer Review by Architect, Guy Marriage
Architect Guy Marriage discusses why he chose a Pyro Fire for ‘Stilt House’, as seen on Grand Designs NZ episode 12.
“The Pyro Classic has been developed to be the most fuel efficient firebox that you can get in New Zealand and that’s why we wanted one.”
Heat Sustainer FAQ
Why do the majority of fireplaces on the market come with inefficient steel fireboxes rather than full ceramic chambers?
Great question. Steel fireboxes are generally cheaper and easier to mass produce. It’s as simple as that really.
Is this [insert expensive, high-end fireplace] with a square, steel firebox not efficient?
Because the steel can’t retain heat and its shape won’t allow for cicular encapsulation, it won’t be as efficient as it could be.
How does the Heat Sustainer keep me warm after the fire has burned down?
Firstly, the Heat Sustainer is able to absorb and store an abundance of heat thanks to its large size. Secondly, ceramic loses heat at a much slower rate than steel which means once your fire burns down, the Heat Sustainer will continue to release that stored heat evenly over a number of hours.
I've heard that the Heat Sustainer can provide up to a 12 hour burn time. Is it true or just marketing fluff?

Environmentally Conscious Choice
Pyro Fires are Ultra Low Emissions Burners
All Pyro Fires are low emission burners, with an emissions rate of only 0.3g/kg – less than half that of most other clean air wood fires. Due to the impressive heat storage capabilities of the fire chamber, Pyro Fires consume considerably less firewood. At a fuel consumption rate of only 0.9kg per hour for the Pyro Mini and 1.1kg per hour for the Pyro Classic, a Pyro Fire is a smart choice for the environment and your wallet!
Up To 100 Colour Options
