HOW TO CHOOSE A POOL HEATER SIZE
First determine the desired temperature difference by subtracting the coldest average air temperature when the pool will be in use from the desired pool water temperature. [Example: 85F (desired pool water temperature) - 60F (temperature when pool is opened) = 25F difference.] Then, using the Pool Heater Sizing chart below, select the appropriate heater model number. Sizing chart based on 3-1/2 mph average wind and average pool depth of 5-1/2 feet. Blue figures based on zero wind. HOW TO CHOOSE A SPA HEATER SIZE Identify the number of gallons your spa holds. Decide the heat-up time desired, and note on the chart which Laars LX/LT model is recommended. The chart indicates the approximate time required to raise the spa temperature 30F. A model number 250 heater on a 600 gallon spa will take approximately 45 minutes to raise temperature approximately 30F (depending on wind, insulation, etc.) Please see your area sales rep for more information. |
