How does water flow through a pool heater?
Water exits the pump into the pool’s filter. This is a large cartridge that has a filter inside. After the filter, water goes into the pool heater or solar heat. Usually, there is a water bypass valve right at the heater’s intake that would allow water flow to go around the heater (if not in use) instead of through it.
What monitors water flow in a pool heater?
WATER PRESSURE SWITCH – This switch monitors water flow and pressure inside the header. If the switch senses that the water flow and pressure are either too low or too high, it shuts off the system.

What happens when there is low flow in a pool heater?
Heaters have high limit switches for temperature, pressure, and refrigerant (if a heat pump) that will open and shut off the heater in a low-flow scenario. In a heat pump, when the flow is low, the system will run high head pressure. In a gas heater, the exchanger can begin to cavitate and make a loud banging noise.
Where does the heat come from in a pool heater?
Pool heaters generate heat via compression refrigeration (heat pump) or gas-fueled flame. This heat gets passed off into the water through the heat exchanger inside the pool heater. Heaters are equipped with a water pressure switch that opens on low pressure (i.e., pump off or flow restriction).

What’s the difference between Jandy and Hayward pool heaters?
When it comes to troubleshooting Hayward pool heaters, there’s not too much difference between the problem solving process for other gas-fired heaters, made by Jandy, Pentair or Raypak. The components of a Hayward pool heater are also very similar to gas heaters made by other manufacturers.
What kind of material is a Hayward pool heater made of?
The heat exchanger in your Hayward pool heater is made from the highest quality of copper and nickel (Cupronickel) materials. The premium materials and the exacting processes used in the manufacture of the heat exchanger is state
How can I troubleshoot my pool heater problem?
Troubleshooting pool heaters is a methodical process; or a process of elimination really. First eliminate water flow issues, then gas flow issues, and finally the low voltage electric currents that run between pool heater components.
