Dega Gas Spa Heaters - aka De-Gas

Dega / De-Gas Spa Heaters

 Dega / Onga / De-gas gas spa heaters were one of the best, long-running gas heaters around. These were a fairly efficient bypass style heater, with built-in timer that controlled the pump, and also an air switch. They were well ahead of their time. We carry several spare parts that no other company carries. 

Dega Gas Heater LPG & Natural Gas

The most common 100mJ and 200mJ gas spa heaters. Note that these aren't truly that rating, as they were restricted by use of a regulator on the incoming gas line. 

Dega Quiptron Skid Pack

Very common Dega Skidpack included gas heater, pump, cartridge filter, and blower.

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. In some cases they may be repaired.
  • Air Switch - these sometimes break or fail. This is a repairable part
  • Timer - This is a repairable part
