Wood Pellet Boilers

At Tubman Heating we are actively researching and sourcing sustainable and environmentally friendly options to help our clients manage their climate change response. A viable alternative to conventional and electric boilers, wood pellet burners use compressed wood pellets as the fuel source. The wood pellets in New Zealand are all made of sawdust and wood shavings, manufactured locally in Kerikeri, Taupo, Nelson and Invercargill.

ÖkoFEN Pellet Boilers

As the preferred installers of the ÖkoFEN pellet boilers we can supply, install and service the pellet boiler, controls and rest of the heating system. ÖkoFEN pellet boilers come in 64kW modules and can be cascaded up to 512kW – or more if required for the heat load. They are perfectly designed for retrofit applications where space and access is tight, with a 64kW boiler fitting through a standard 0.8m doorway. The boilers are fully automatic in all their operation, including refuelling, meaning very low maintenance and operation costs. Our design team can tailor a suitable solution for your organisation.
