ÖkoFEN Energy Box - Containerised Pellet Boiler Plant Room

Designed for commercial central heating or process heating situations where space is problematic, the ÖkoFEN Energy Box system takes up around two carparks. Used for hot water and central heating systems. Examples of installations include: University halls of residence, primary schools, hospitals, retirement homes, green house heating and more.

• Fully automated operation — vacuum fuel supply, ash cleaning, email notification for reordering fuel and faults
• Uses wood pellets — 100% renewable fuel, made in New Zealand from waste sawdust, with an existing delivery network throughout the country
• Lowest carbon emissions of any heating fuel in NZ - 0.003 kgCO2e/kWh (98.5% reduction vs. natural gas or LPG)
• Delivered pellet fuel price averages 7c/kWh for commercial installations across NZ
• Provides high temperature water for any heating system — underfloor pipes, radiators, fan coil units
• Delivers large volumes of domestic hot water and/or heat for swimming pools or spas
• Wide range of sizes to heat any residential or commercial building up to 9,000m2
• Boiler operation is very highly controlled with wide modulation range — optimises operation in temperate New Zealand climate with varying heat loads during the day
• Standard efficiency boilers are 93%, up to 103% efficiency with condensing pellet boilers
• BMS and internet connected for remote monitoring, error notification and continuous commissioning
• Spare parts held in New Zealand, service agents throughout country for repairs and maintenance

• 100,00 tonnes of wood pellets (pellets) are made annually in New Zealand from wood waste (sawdust, shavings) in Taupo, Nelson, Invercargill, and Dargaville
• Pellets provide 100% renewable energy with the lowest carbon intensity of any distributed energy in New Zealand
• Pellet CO2 emissions of 0.003 kg CO2e/kWh
• Comparable CO2 emissions (CO2e/kWh) are natural gas at 0.195, LPG at 0.222, diesel at 0.266, electricity at 0.0977, heat pump with average COP of 3 has CO2 emissions of 0.033 (plus consideration of GWP of refrigerant)
• Average cost of fuel for commercial applications is $0.07 per kWh delivered, excluding GST
• National distribution network existing for simple, safe, low impact fuel delivery service
• Blower truck delivery can be completed with a truck up to 20m from plant room / Energy Box
• No risk of explosion or self-ignition of fuel
• Pellets do not burn without forced air circulation, in a building fire the bulk fuel store will only smoulder
• No requirements for containing spillages from environment
• No noxious emissions from boilers, minimal flue gas emissions, meets Regional Council Air Shed requirements
• Avoids Global Warming Potential of refrigerants in heat pumps — 650 to 2,100 times more potent than CO2 when released to atmosphere
