Pool heaters
Pool heaters are now standard in cold areas of the country. Heaters extend the swimming season by two months at end of summer and early spring. There are three main classes of pool heaters:
• Solar – This technology is improving constantly. This method converts the rays of the sun into energy to heat water. Used with a solar blanket, one will gain energy efficiency while warming the water.• Electric – This is great for keeping the temperature between 80 and 90 degrees. Even in 45 degree weather electric heaters are effective enough to allow one to have a comfortable swim. However, this type of heating is expensive to operate.
• Gas – Gas heaters are most effective when used for a short period of time, although the fuel is costly.
What size pool heaters are needed? Most manufacturers recommend that one buy a heater one size larger than the basic requirement. Choose a heater that will keep the water in between 78 and 86 degrees. The size of the heater one may need is measured in BTUs. To learn the approximate BTU required for your pool, multiply the surface area of the pool by the temperature rise by 12. If one assumes a one degree Fahrenheit rise per hour this equation will work.
A pool heater will maximize the value of your pool by allowing one to enjoy very comfortable water temperatures. A good heater can allow one to swim earlier in the season and later in the fall. It can also lengthen the swim day. Pool heaters will increase the value and cost efficiency of the pool.
