How the MasterTemp Pool Heater Works
1. Heating Process & Core Components
Gas Combustion System: Utilizes natural gas or propane in a sealed combustion chamber
Cupro-Nickel Heat Exchanger: Features a vertical tube design for maximum heat transfer efficiency
Electronic Ignition System: Energy-saving hot surface ignition (no standing pilot light)
Microprocessor Control: Precisely regulates water temperature (±1°F accuracy)
2. Step-by-Step Operation
Water enters through the inlet and passes through the filter system
Flow switch activates when sufficient water flow is detected
Control board initiates the heating sequence
Gas valve opens and hot surface igniter activates
Combustion occurs in the sealed chamber
Water circulates through the vertical heat exchanger tubes
Heated water returns to the pool at the set temperature
3. Advanced Control Systems
Thermal Regulation: Automatically adjusts gas valve operation
Self-Diagnostic Capabilities: Continuously monitors system status
Freeze Protection: Activates when ambient temperature drops below 45°F
