Pool Heater Controllers

Pool Heater Controllers

Pool heater controllers are used to manage temperature, automate heating cycles and improve the efficiency of pool heating systems. Whether you are installing a solar pool heater controller, replacing a faulty unit or upgrading to a trusted Dontek solar controller, the right controller helps your system run more accurately and efficiently.

A quality pool heater controller acts as the control centre of your heating system, switching pumps, valves or heating functions only when required. This helps reduce wasted energy, maintain a more consistent pool temperature and improve overall system performance.

This collection includes pool heating controllers suited to a range of applications, including:

  • Solar pool heater controllers
  • Dontek solar controllers
  • Pool temperature controllers
  • Replacement controllers for pool heating systems
  • Controllers for residential and commercial pool heating setups

Select the right pool heater controller below to improve heating performance, automate operation and maintain better temperature control. Fast Australia-wide delivery available.

What a Pool Heater Controller Does

A pool heater controller regulates when your heating system operates and how it responds to temperature conditions. In a solar heating system, the controller compares temperatures and activates circulation only when solar gain is available. In other systems, the controller manages temperature settings and heating demand so the pool remains at the desired level without unnecessary operation.

Solar Pool Heater Controllers

A solar pool heater controller is designed to maximise free heat from the sun by operating the system only when roof collector temperatures are higher than pool water temperature. This improves efficiency and reduces pump run time. Solar controllers are an essential component in any well-functioning solar pool heating system.

Dontek Solar Controllers

Dontek solar controllers are widely used across Australia due to their reliability, simple operation and proven compatibility with many solar pool heating systems. They are designed for Australian conditions and are a popular choice for both replacement installations and new solar heating setups.

Signs a Pool Heater Controller May Need Replacing

  • Incorrect or unstable temperature readings
  • Solar heating not activating when expected
  • Pump or valve operation becoming inconsistent
  • Heating system running too often or not at all
  • Display faults, sensor errors or control issues

If your pool heating system is not responding correctly, a faulty controller or sensor may be the cause. Replacing the controller can often restore proper operation without replacing the entire heating system.

Choosing the Correct Pool Heater Controller

The correct controller depends on the type of heating system installed. Solar systems require solar-specific controllers, while other pool heating systems may use digital temperature controllers or integrated automation systems. Always confirm compatibility with your existing heater, sensors and valves before ordering.

Benefits of Replacing an Old or Faulty Controller

  • Improved heating efficiency
  • Better temperature accuracy
  • Reduced unnecessary pump run time
  • Lower energy consumption
  • More reliable day-to-day pool heating performance

Upgrading a worn or outdated pool heater controller is often one of the most cost-effective ways to improve the performance of a pool heating system.
