Diesel boilers are compact, powerful, virtually silent, odourless and smokeless. They are the ideal heat source for warm water central heating systems. Particularly radiator systems.
There are more than 10,000 diesel boilers installed residentially in New Zealand for warm water central heating. 5000 of them are Firebird boilers from Central Heating New Zealand, due to their efficiency, robustness and reliability.
These floor-standing boilers are slightly smaller than a modern washing machine and are typical installed in a garage or laundry. External models are also available which are installed outside and come with an integral flue.
Diesel boilers require the installation of a fuel tank which is located outside the house. The tanks come in two sizes, 460 and 880 litres and are slightly larger than 2 x LPG tanks. Fuel tanks are installed on a concrete pad in an area accessible for refuelling which could be up to 50 metres away from the boiler. Diesel fuel delivery is readily available in all urban and rural areas in New Zealand.
