Coates Electric Swimming Pool Heaters

Coates electric swimming pool heaters are medium capacity heaters that have a built-in flow switch to allow operation at water flow rates of 20 gpm to 80 gpm and to prevent operation when there is no water flow. An all stainless steel tank for long life and corrosion resistance is also standard. Other standard features include incolony heating elements, close differential thermostat, manual reset hi-limit, flow switch, elements & flow switch "on" lights, UL listed for Indoor/Outdoor installation and internal protective fusing in units over 48 amps.

When a pool is in frequent use, a pool heater to make upheat loss may be all that is needed. Use the following calculations to properly size the heater:

Swimming Pool Heater Sizing:

• Surface Area of the Pool (sq. ft.) = length x width
• Desired Pool Water Temperature: °F
• Average Outdoor Air Temperature: during months in use
• Temperature Differential: Different between air and pool temperatures during the coldest month of use (desired pool temp. minus average air temp.)
• KW Required = Pool Surface Area x Temperature Differential x 12
3413
Assumes a heat loss of 12 BTU/hour per square foot per °F of temperature difference between pool and air. 1KW=3,413 BTU/hour

Spa Heater Sizing:

• When the rate of recovery and the spa heat-up time are important, or when the spa is used frequently, use the following calculations.
• Capacity of Spa In Gallons = Length x Width x Average Depth x 7.5 (gal./cu. ft.) -OR- Surface Area x Area Depth x 7.5 (gal./cu. ft.)
• Desired Water Temperature Rise Per Hour: °F
• KW Required = Gallon Capacity x 8.3 (lbs./gal.) x Temp. rise °F/hr
