How does a millivolt pool heater work?
Millivolt Ignition This generator uses the heat of the pilot flame to generate small amounts of power (milli-voltage, or thousands of a volt). This trickle of power is then used to operate the rest of the system. The advantage of using millivolt ignition is that no electrical power needs to be supplied to the heater.

How does a sensor work on a pool heater?
Pool heater sensors are made to regulate the temperature of the water coming through your heat pump. The sensor keeps track of the water’s current temperature, so it starts heating when it falls below the required freezing point. The heating continues until it gets to the desired temperature. Then, the sensor signals back to the heater to stop.
