Model # CSPAXI55
Hayward electric spa heaters contain all of the sophisticated features and capabilities of heaters twice their size. The electric heaters fit into compact spaces - even under spa skirts or steps. Like all Hayward heaters, they are easy to install and service.
The literature indicates it is for up to 400 gallon spas. I'm hoping to use it on a 1,500 gallon (therapy pool) that sits in a heated shed. Am I just asking for trouble going with something that seems to be undersized? My thinking is that if the room is heated to 65 degrees I shouldn't have a terrible time heating it to 90 degrees as the 400 gallon is probably for heating a spa sitting outside in 20 degree weather to 100 degrees.
Hi, Jeff Boyd. Undersizing a heater or any equipment will cause the unit to be over worked causing it to fail. I would recommend the Electric Spa Heater 11 kW - CSPAXI11 model.
Can this pump be used on a soft sided Coleman pool with steel frame...9'x18'?
Hi, WL. This unit is an electric heater, not a pump. With the correct pvc connections and size pump, it will be able to heat a 9'x18' pool depending on the desired pool temperature.
Will the CSPAXI55 work on 208v 3 phase power
No, that heater works on 240V.
How long does it take to heat (indoors) 800 gallons from 74 F to 84 F
Hi Jeff, Based off of the infomation I've gathered from the Hayward CSPA Series Heater literature, it would take about 3.5 hours for the Electric Spa Heater 5.5 KW to raise a 800 gallon spa 10 degrees.
