Diesel / Oil / KeroseneOil still gives just about the best 'bang for buck' especially in the South Island where Natural Gas is not available ~ a Mistral Condensing Boiler running on Diesel will be operating at about 93% efficiency ~ that's almost 10kWh from every litre of fuel used. Usually installed in a Garage or Utility room they are about the same size as a Dishwasher, and about as noisy as a fridge. We usually install a 480l (or in some cases a 980l) tank outside the property, fuel can be delivered monthly as a top up service via a small mini tanker. Kerosene or heating Oil is still very expensive in New Zealand, as such Heatsmart set up our units to run on Diesel, Diesel prices have been fairly stable over the last few years and running costs equate to around 15c (NZD) per kWh. Oil Boiler systems are fully Automatic on demand units that can be controlled via a simple time-clock & thermostat.
Heatsmart is proudly the sole importer of Mistral Oil Boilers, these high quality, highly efficient Oil Boilers are fully stocked in New Zealand along with a comprehensive range of spares (not that we've needed any in the last 4 years...)
