Smarter Insulation. Longer Swim Seasons.
ECOTHERM™ pool systems are engineered with insulated wall technology designed to help retain heat more efficiently than traditional pool wall systems. By reducing heat loss and capturing warmth gained naturally from the sun, these energy-conscious pool designs help maintain more consistent water temperatures throughout the day and overnight.
The improved insulation performance can help homeowners enjoy:
- Extended swimming seasons
- More comfortable water temperatures
- Reduced overnight heat loss
- Less dependence on pool heaters
- Greater long-term energy efficiency
For homeowners using gas or heat pump pool heaters, retaining heat more effectively can also reduce the amount of energy needed to maintain preferred swimming temperatures. Since many pool owners enjoy water temperatures around 78–82°F, improved heat retention can help reduce heating demands while creating a more comfortable swimming experience. View our stats below.
- Other Pools Water Temperature — 72º F
- ECOTHERM™ Insulated Pool — 82º F
- Other Pools Swimming Season — 40% Annual
- ECOTHERM™ Insulated Pool Swimming Season — 50% Annual
- Other Pools Annual Heating Costs — 90%
- ECOTHERM™ Pool Annual Heating Costs — 60%
With energy-saving performance built directly into the pool design, ECOTHERM™ systems offer a practical solution for homeowners looking for comfort, efficiency, and long-term value in a semi-inground pool.
