ÖkoFEN Boilers for Commercial Central Heating

The ÖkoFEN range is suitable for schools, apartment buildings, retirement homes and larger commercial buildings for domestic hot water and central heating.

Provides 100% renewable heat energy in commercial and high-end residential buildings for:

• Central heating
• Domestic hot water
• Pool and spa heating
• Process heat

Cascade systems are available for a range of building sizes and applications up to 512kW

Provides heating for any central heating distribution system:

• Underfloor pipes
• Radiators
• Ran coil units

• 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
