For many years, guests have enjoyed and luxuriated in the ‘Tween Waters’ Olympic-sized pool, and now more than ever, that experience is to be celebrated. As a leader in green policies, Sanibel Captiva Beach Resorts has partnered with Symbiont to install a GeoThermal heating units, which use the earth’s heat to warm or cool the pool — making these the greenest pools on Sanibel and Captiva Islands.

This time of year, with air temperatures in the 80s and 90s, keeping the pools at a refreshing temp actually comes from the earth’s heat! The GeoThermal unit can both warm and cool the pools at ‘Tween Waters. This works by utilizing the heat of the earth to transfer energy, rather than employing the heat of the earth as the heating source.

Utilizing two wells, one to bring the water from earth, and another that transfers to a heat pump, this geo-thermal process utilizes water in the ground and then returns back to the ground. This process is 30% more efficient than a traditional heat pump that uses air, and 80% more efficient than a heat pump that uses gas (what most hotels use to heat their pools). This all results in less energy being used, less waste and more use of our natural resources to provide an eco-friendly swimming experience. Plus with two pools to heat and cool at ‘Tween Waters, that’s double the energy savings!

Not only is geo-thermal heating more eco-friendly, but it’s also economical and reliable, meaning the hotel saves money on gas bills and can utilize that budget toward additional hotel improvements. This system also lasts 15-20 years (whereas a typical gas system lasts between 5-10 years) meaning less breakdowns and repairs, meaning guests will enjoy the pool all year round without issue!

This installment isn’t new — the ‘Tween Waters has been using GeoThermal energy for a few years, but the significance of how ‘Tween is staying green makes this newsworthy.
