## Features

- [Self-Heating]: When the water temperature reaches the preset temperature, the pool heater will automatically stop. And when the temperature is lower than the preset temperature, the heater will automatically turn on again.
- [Dry Burning Prevention]: The swimming pool heater is equipped with a pressure switch to protect it from the risk of dry burning due to lack of water in the operating process. If the water pressure drops to 15kPa or less during operation, the pressure switch will shut off the power.
- [High Temperature Protection]: The hot tub heater has a high temperature protection switch. When the temperature reaches 50°C due to a lack of water flow or a blockage in the inlet, the heater will trip (cut off power).
- [Wiring Method]: Pool heater typically do not come with a standard plug attached because it often requires higher voltage and current levels compared to standard household appliances. Instead, they are designed to be hardwired or connected using specialized connectors. High power heater can achieve better heating effect, so we recommend that you invite an electrician to help you wiring.
- [Notice]: The pool thermostat is suitable for pools around 500 gallons. In addition, the electric pool heaters come with 2 different pvc pipe connectors. One inner diameter is 48mm (1.88"), and the other is 50mm (2"); [Tips] It is recommended to use SCH 40 1.5inch pvc pipe.
