  • SP 155K is a smaller solar pool heat exchanger that is typically used in conjunction with an existing pool heater and solar.  This unit will do a good job of maintaining the water temperatures initially supplied by an auxiliary heat source such as a gas heater.  Total Heat exchange surface area is .34 M2 (3.66 ft2)

  • SP 300K is a larger solar pool heat exchanger that can be used with a larger solar system as the primary heat source.  Sizing the pool collectors is important for proper operation of a solar pool heater.  Total Heat exchange surface area is .65 M2 (7 ft2)
