The SYMBIONT™ GeoThermal Water Source Pool Heater
What is The SYMBIONT™?
The SYMBIONT™ is a dedicated water source (water-to-water) GeoThermal pool and spa heat pump for residential and commercial applications.
Unlike gas pool heaters, the SYMBIONT™ uses naturally stored heat from a stable water source to efficiently heat and cool your pool or spa. This results in operating costs typically 70% to 90% lower than gas and reliable, year-round performance unaffected by outdoor weather conditions, unlike air source and solar.
The SYMBIONT™ is an eco-friendly, green heating solution with an expected service life of 15 to 20 years, compared to the 5 to 10 year lifespan of most conventional pool heaters. For long-term operating cost, dependability, and sustainability, the SYMBIONT™ stands apart.

How a SYMBIONT™ GeoThermal Pool Heater Works
Water Source Pool Heating Explained
When the pool pump is running and the thermostat calls for heat, the SYMBIONT™ pool heater and source water pump activate to warm your pool or spa.
Like all heat pumps, the SYMBIONT™ uses a refrigerant vapor compression cycle to move heat from one place to another. It captures free, renewable heat from a water source—such as a lake, canal, or aquifer well—and efficiently transfers that heat into your pool or spa. The only energy you pay for is the electricity required to operate the compressor and circulation pumps.
The diagrams below illustrate the heating cycle of a SYMBIONT™ GeoThermal water source heat pump, shown with two common heat sources: lake water and aquifer wells.

The GeoThermal Water Source Heating Cycle
Like any heat pump, the Symbiont™ extracts heat from one place (The Source Water) and delivers it to another (The Pool Water). The diagram above shows the main components in this process. When the thermostat senses the pool needs heat, the system cycles on to start the process. The compressor moves refrigerant through the system, absorbing heat from the source water and transferring that heat to the pool water. The two waters do not mix. This cycle continues until the pool reaches its desired temperature, and the system will turn off.
Using Lake Water as the Heat Source for GeoThermal
As illustrated, pool water passes by the Thermostat and through the heater prior to returning to the pool. When the Thermostat senses the pool needs heat the system cycles on and lake pump begins to deliver water to the heater. The lake water and the pool water never mix. The Symbiont then transfers free heat stored in the lake water to the pool water through a refrigerant cycle detailed in a separate diagram. The transfer of free heat in a water to water system (GeoThermal) is much more efficient than that of an air to water system (standard heat pumps) or a heat generated system (gas heater). When the pool has reach the desired temperature the heater(s) and the lake pump will cycle off.


Using Aquifer Wells as the Heat Source for GeoThermal
As illustrated, pool water passes by the Thermostat and through the water source heater prior to returning to the pool. When the Thermostat senses the pool needs heat the system cycles on and well pump begins to deliver water to the heater. The well water and the pool water never mix. The Symbiont then transfers free heat stored in the well water to the pool water through a refrigerant cycle detailed in a separate diagram. The transfer of free heat in a water to water system (GeoThermal) is much more efficient than that of an air to water system (standard heat pumps) or a heat generated system (gas heater). Because the ground water remains a constant temperature throughout the year, the Symbiont GeoThermal system can exceed the performance of either the standard heat pumps or the gas heaters. When the pool has reached the desired temperature the heater(s) and well pump will cycle off.
