Research and reports

An opportunity has arisen for the New Zealand Defence Force to improve the economics surrounding the operation of the Burnham site heating system.

This report evaluates the opportunity to convert or replace coal fired boilers to woody biomass and offers technical recommendations. Options are considered for plant replacement, plant conversion, or use of woody biomass as a duel fuel source.

Within its property portfolio, Manakau City Council has a range of premises, predominantly swimming pools, which are suited for conversion to wood as the principle source of heat energy.
Such a move would bring both cost savings and improved  environmental performance, whilst at the same time retaining value from the Council's expenditureon energy in the local economy

This study carried out by Aircomm Consultants Limited for Queenstown Lakes District Council investigates the feasibility of a district heating scheme to supply heating to Queenstown Airport, Lakes District Hospital, Alpine Aqualand (swimming pool) and the Queenstown Events Centre.

The centralised wood-chip boiler plant described in the study is not considered to be feasible in this situation.

The Invercargill City Council Parks Department has installed a wood chip boiler at their plant nursery. The new boiler replaces a coal boiler and provides heating to approximately 450 square metres of greenhouses. This monitoring report outlines how the installation went.
