Bioethanol fuel bottles for a suspended fireplace in New Zealand

A bioethanol fireplace in New Zealand costs roughly $2 to $6.50 an hour to run, depending on the size of the burner and how high you set the flame. Bioethanol fuel sells for about $5.50 to $5.75 a litre in 20 L lots. Here is what that means for each fire we make.

How much is bioethanol fuel in NZ?

Our bioethanol fuel comes as four 5 L bottles (20 L). It is $110 unscented or $115 scented, which works out at $5.50 to $5.75 a litre. We deliver fuel within New Zealand only.

Running cost per hour by fire

Fire Burner and tank Heat output Burn time per fill Approx. cost per hour
Sphere XL500, 5 L 3.35 kW 10 to 13 hours $2 to $3
Curve 90, Orbit, Silo XL700, 7 L 4 kW 9 to 12 hours $3.20 to $4.50
Curve 120 XL900, 9 L 4.4 kW 8 to 13 hours $3.80 to $6.50
Cocoon Aeris 1.5 L 3 kW Up to 5 hours From about $1.70

The range in each row comes from the flame setting. A lower flame burns longer on the same fill, so the cost per hour falls.

What a typical winter evening costs

Run a Sphere for four hours on a winter evening and you will use about 1.5 to 2 L of fuel, or roughly $8 to $11. A Curve 120 on a high flame for the same four hours uses closer to 3 to 4.5 L.

Is a bioethanol fireplace a heater or a feature?

Both, but be realistic. At 3.35 to 4.4 kW a Naked Flame bioethanol burner gives real warmth to the space around it, and every burner has a minimum room size (80 m³ for the Sphere, 90 m³ for the XL700 fires, 110 m³ for the Curve 120). In a large, open-plan New Zealand home it works best alongside your main heating, as the focal point of the room.

Are bioethanol fires safe?

Bioethanol burns cleanly, producing mainly heat, water vapour and carbon dioxide, so it needs no exhaust flue to the roof. Use it as the manufacturer intends: refill only when the burner is out and cool, light it with a long lighter, keep the room ventilated and respect the minimum room volume.
