Most people find that water
between 75° and 80° is ideal for swimming. Yet, only in certain
areas, such as Southern California Southern Florida, does the
sun maintain water temperature above 75°
three months of the year. And the swimming season-and swimming
day -in even these areas could be stretched by the use of a pool
heater. |

Note 1. These heat
losses are based on an assumed wind velocity at the water surface of 5 m.p.h. and an
ambient temperature of 60°F.
Note 2. Where surface area and gallons do not coincide, surface area must take precedence.
For more information on heat loss from spa surfaces, contact Thermo-Dynamics.
