Product Highlights
The AquaHeat Gas-Fired Heating System is a highly efficient way to heat your aquaponic or hydroponic system. Runs on natural gas or off-grid propane.

AquaHeat is the latest in efficient natural gas or propane-fired heating for your aquaponic system.

Description
AquaHeat Propane or Natural Gas-Fired Heating System
The AquaHeat Aquaponic and Hydroponic water heating system was designed with reliability and ease-of-use in mind. The AquaHeat comes fully assembled, mounted, and tested.
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 repeats.
System Features
- All AquaHeat systems come with a natural gas or propane hot water heater. The heater unit must be vented following the instructions provided with the unit.
- The entire heating system can be run off a car battery with the supplied 12 v battery cable
- DC circulation pump – used for circulating hot water through the stainless steel heat exchanger and the heater unit.
- Thermostat controller and sensor wire
- 50′ Compact Stainless Steel Immersion Coil
- Fully Mounted and plumbed on backer board
- Ready for hookup to gas service
