How to turn on Hayward pool heater?

1. Safety Considerations

It is important to follow all safety guidelines when operating a Hayward pool heater, as improper use can lead to serious injury or property damage. Make sure that the electricity supply for the heater is off before attempting any maintenance on it. Additionally, always read and understand the manufacturer’s instructions before handling any heating device.

2. Finding the Switch

The switch for your Hayward pool heater will usually be located near the filter system of your pool, but depending on where you installed it this could vary slightly. Also, you may need to remove some panels or covers in order to access the switch so make sure you are well familiar with your set-up beforehand. If unsure, consult a professional who specializes in pool maintenance.

3. Turning on the Heater

Once you have located the switch for your Hayward pool heater, it should be relatively simple to operate it. Simply turn on the power supply and then flick the switch up or down depending on which model of the heater you have (up for electric heaters, down for gas). The indicator light should come on when you are turning it on.

4. Setting The Temperature

Depending on what type of Hayward pool heater you have, there may be a temperature setting that needs to be specified before it can begin heating your pool water. To do this, locate the control dial or panel and set the desired temperature range within the manufacturer’s guidelines. If unsure about how to set the temperature, consult a professional who specializes in pool maintenance.

5. Testing The Heater

Once the Hayward pool heater has been turned on and the desired temperature range has been set, it is important to test its efficiency. To do this, wait for a few hours and then check the water temperature with a thermometer. If it is not up to the specified level after several hours of operation, then you may need to seek further advice or assistance from a professional.

6. Maintaining Your Heater

In order for your Hayward pool heater to be effective over time and remain in good working condition, regular maintenance should be carried out according to manufacturer instructions. This could involve cleaning filters, checking wiring and hoses, and making sure that all parts are functioning correctly. Regular maintenance will help to ensure the heater is always in optimal condition for use.

7. Troubleshooting

If your Hayward pool heater is not heating up as expected or if any other issues arise, then there are a few steps you can take before consulting a professional about the problem. Firstly, check whether all relevant power sources are on and that no electrical components have been disconnected or damaged. Secondly, check the settings of the temperature control to make sure it is set at the correct level. Lastly, examine the filter system for any blockages that may be impeding airflow or water flow. If none of these steps resolve your issue then it is best to contact a professional pool maintenance service.


Always remember to follow the manufacturer’s instructions when handling any heating device, as serious injury or property damage can occur if these are not followed properly. Additionally, regular maintenance of your heater will help it to last longer and stay in good condition. If ever in doubt, then seek assistance from a qualified professional who specializes in pool maintenance.
