AquaCal Geothermal Water Source Pool Heating Systems

AquaCal Geothermal Watersource Heat PumpWater Source Pool Heating Applications
Water Source heat pumps bring the warmth of the tropics or the cool of the mountains to your backyard or community swimming pool and spa. The Water Source transfers free heat from nearby wells, lakes, canals, or oceans to your swimming pool. It's safe, efficient, and gentle on the environment.

Features & Benefits


ThermoLink Patented Titanium Heat Exchanger* (WS03 and WS05 only)
Best warranty in its class
Electronic control and monitoring system
Attractive marine grade aluminum for strength and durability
Super efficient scroll compressor
Dual pool and spa thermostat standard on all models
Heat and cool standard on WS05 & WS10

If you need a geothermal water to water pool application or a ground water heat pump system for residential, commercial or industrial use, please contact us  or fill out a geothermal inquiry form.

When it comes to heating your pool year round with a pool heat pump, we recommend geothermal water to water pool heaters.  Geothermal heat pump systems can be referred to as Ground Source Heat Pumps (GSHPs) and operate by harvesting heat from the greatest known solar collector in the world: The Earth.

The heat collected from the constant stable ground temperature is then transferred into your pool. This Geothermal swimming pool application works because although the air temperature in the winter could drop in some places to 30 below zero, underground temperature will remain in a constant 40 to 70 degrees depending on your location.

We specialize in Geothermal Water to Water GSHPs. This system can be used when you have a lake, pond or well, where an adequate supply of suitable water is available. The heat from that water source will be collected, concentrated with a heat pump and then applied it on your swimming pool to elevate the water temperature.

Note: Water to water heat pump models are specifically built for swimming pool heating only. If you need a Water to Water heat pump for a residential or commercial building heating applications please let us know as we have other models built especially for that application.

How Does Geothermal Work?

Water to water Geothermal pool heating systems are known either as Open Loop or Closed Loop. The advantage of an open loop system (existing well or lake on the property) versus a closed loop system (buried pipes) is that with the open loop the upfront investment can be much less than in a closed loop geothermal system as you have less materials, less construction, earth excavation and as a result, there are less labor costs.

 The difference between a Water Source Heat Pump (water to water) and an Air Source Heat Pump (air to water) is in a water to water the heater is geothermal and comes from the earth. In air to water heat pumps the heat is taken from the outside air and transferred to the water. that is a good way when the temperatures are above 45 degrees as they are for most people's swimming seasons. If you have an indoor pool in a cold weather state you need to go geothermal or air to water with a gas or electric element back up for the winter.

Geothermal Benefits

The benefits of a Geothermal pool application are that you will never have to worry that it is too cold outside for your heat pump to operate at 100% of its capacity. The ground is always warm to a heat pump.
