Safety & Heater Protection…

To meet relevant gas codes, a pressure relief valve (45psi) is required to be fitted if the water from the Pool or Spa can be shut off 100% to the heater either by valve or any other means. Failure to do this can result in damage to the gas pool or spa heater. Contact us for further information.


flow switch is required when the location of the heater is either 1 metre higher or lower than the pool water surface otherwise the pool’s pressure switch may not operate correctly. The flow switch is an ideal secondary safety system to protect your pool heater. Contact us for further information.


Important note: When installing new gas appliances (or even when replacing existing gas appliances whether they are natural gas or propane – LPG) your gas fitter is obliged to give you a Certificate Of Compliance. This is required under the Gas Codes.
