How it Works:
When properly installed and operational, the AquaHeat will perform in the following manner.
- Propane or Natural Gas is supplied to the AquaHeat unit. (Unit must be properly connected to gas service and tested following instructions)
- Power is supplied to the digital thermostat controller
- The temperature drops below the set point, measured by the thermostat wire in your sump or fish tank
- The digital thermostat controller activates the DC circulation pump to move water through the heat loop (indicated with a mechanical pump sound)
- Water pressure activates gas flow (indicated with slight hissing sound)
- Water pressure also triggers the igniter which is powered by the D batteries (indicated by clicking sound)
- Gas ignites flame to start the burners and heat water
- Water is recirculated through the AquaHeat and the stainless steel heat exchanger (located in your sump or fish tank). The heat exchanger should always be submerged.
- Heat is exchanged between the heat exchange coil and the water in your aquaponic system.
- Once the temperature reaches the high temp set point, the thermostat turns off the DC circulation pump.
- This in turn shuts off the gas flow and allows the boiler to cool down.
- Once the thermostat detects the system water has cooled below the low set point, the process
