More information

Additional Information

Dega heaters were made obsolete in the late 1990s. The last of the heaters still used older parts. They were an Australian heater, with many Japanese parts.  


They were different in that many of the components ran on 110v, rather than 240v.

Common Faults:

  • Flow Switch - If heater allows pump to run for a few seconds, and then switches off, this is likely the culprit.
  • Ignition Coil - if no zapping is heard, this may be the fault.
  • Gas Valve - has 2 solenoids that can fail. 
  • Gas Regulator - these were all meant to be covered. If it has been outdoors, it should be replaced.
  • Heat Exchanger - as a bypass heater, the heat exchanger should last for many many years. They only leak when water has been corrosive for some time. 
  • Controller - these may short out. .
  • Air Switch - these sometimes break or fail. 
  • Timer
