Another Look at Our Geothermal Heating Systems in Action
How Can We Help You? Contact Us Today
As you know, our team recently installed a large geothermal pool heating system at Eagle Lakes Community Park, and today we’re continuing our overview of how it works. If you happened to miss our first installment, you can check out part one here.
Once again, you can follow along in the video above to see Mike Jaques, one of our team members, explain it step by step.
The systems we installed are heating four different pools at the park: the lap pool, family pool, slide tower, and wading pool. To recap, there are three main components of a pool heater: the pool water coil, the source water coil, and the freon system. Also, there are two types of water that are pumped through pool heaters: pool water and source water. Because we have four separate pools, we have four pool water bypasses that pump water through the pool heaters and into to the pools.
There are three different types of source water that can be used for pools: closed loop water, lake water, and aquifer wells. This system is using aquifer wells, and we have two six-inch supply wells and two six-inch return wells on the other end of the property.

Each supply well is activated differently.

The first supply well supplies source water for the lap pool through five PH 215 heaters. The second supplies water to the wading pool, the slide tower, and the family pool.
Each supply well is activated differently. When the lap pool system activates, it sends a signal to the variable frequency drive that’s connected to the submersible well pump. Water is then pushed through the pump and back to the return well.
The supply well for the other three wells is activated by a pressure system we installed. When one of the pools needs heat and signals for source water, an automatic valve is opened, and however much water is needed for that pool gets supplied. This allows us to control the amount of speed and energy the source water pump uses.
If you have any other questions or would like more information, feel free to give us a call or send us an email. We look forward to hearing from you soon.
