- The chip heater is a single point, tankless, domestic hot water system popular in Australia and New Zealand from the 1880s until the 1960s. Examples of this form of domestic water heater are still in use. The chip heater consisted of a cylindrical unit with a fire box and flue, through which a water pipe was run. Water was drawn from a cold water tank and circulated through the fire box. When heated, the water was drawn off to the area where it was used, typically in a bath or shower. There was often an ash box under the fire box, which allowed air under the fire, as well as various dampers in the flue. The fire box was relatively small and fed by tinder, such as newspaper, pine cones, small twigs, or wood chips. The use of the later gave the chip heater its name. Water had to be run at a trickle in order to heat up to a desirable temperature. The rate of combustion was controlled by the flues and the ash box. With a lot of fuel and open flues the water could boil quickly, which was not a desirable result. With practice, the correct combination of fuel, flue settings, and water flow, could result in enough hot water for a shower or bath in approximately 20 minutes. (en)
