How to calculate the size of a pool heater?
Heater size in BTU/hr. = Surface Area x Temperature difference x 12, where Surface Area is the area of the pool in square feet, temperature difference is the result of (desired pool temperature – current pool temperature), and 12 is our constant number based on the assumption that wind speed is around 3.5 miles per hour.
How much energy does it take to heat a pool?
These clear, inflatable disks float on the surface of your pool and heat the water. One ring transfers up to 21,000 BTU a day. A ring is generally 59 inches in diameter, so buy enough rings to cover approximately 80% of your pool. Rings will generally last five years and cost up to twenty dollars each.
How does a pool heater maintain the temperature?
A pool is essentially a large water body sitting out in the open, and it loses both heat and mass over time to the atmospheric air through evaporation. Once your pool heater has brought the water temperature up to a comfortable level for swimming, it must also maintain the temperature caused by heat loss from the water surface.
How many BTUs does a pool heater need?
A BTU or British Thermal Unit is the standard for measuring heating capacity and most pool heaters will be described in terms of their BTU output. What we will do first is work out the number of BTUs you will need to increase the water temperature of your pool by 1⁰F in one day.
How much does it cost to heat a swimming pool?
Selecting a comfortable water temperature is subjective, but just a few degrees can mean a significant difference in energy usage. In Atlanta, for example, the annual cost of heating the same size uncovered pool to a temperature of 78 degrees is $840.
