Heat Siphon® Swimming Pool Heat Pumps "Lets get analyzed!!" ANSWER BOOK

What Size Heat Siphon? That depends on your pool surface area. Not sure what size your pool is? - Download FREE POOL CALCULATOR - (Excel Spreadsheet) There are three basic sizes / models of Heat Siphon, all based on the Compressor Horsepower: 2.25HP, 3.25HP and 5.0HP. Sizing depends on your pools heat loss. Determining pool heat loss is quite complex, but some simple assumptions apply to both the higher latitudes and the warm tropics: 1. Most people swim when the daily average air temperature is over 70°F (21°C). 2. Most pool owners do not use a solar cover except in the coldest months. 3. Most pools are kept about 10°F (5°C) above the average air temperature. 4. Since pools lose about 75% of there heat due to evaporation of the water, a pool heater should be sized based on the pool surface area. Based on the above we have found the following true about 90% of the time: A 3.25HP Heat Siphon will heat pools between 500 sq ft (47 M sq) and 700 sq ft (65 M sq) in surface area even with little or no solar cover use. Larger pools between 800 sq ft (75 M sq) and 1000 sq ft (93 M sq) will need a 5HP Heat Siphon and a solar blanket in the coldest month and in very windy locations. The 2.25HP Heat Siphon is limited to very small inground or normal above ground pools If these assumptions don't not apply to your pool we'll be happy to FAX, mail or email you a FREE COMPUTER PRINTOUT OF OUR HEAT SIPHONALYSIS to pick the right Heat Siphon for your pool.(click below)
