Flow Thru Heaters
Show: 

Hot Tub flow-thru heater assemblies. Complete electric spa heaters, or you can purchase just the hot tub heater element. When ordering spa heaters, make sure you order the correct voltage (120v or 240v) and kilowatt rating of the heater. Some heaters have sensors mounted within while other older style heaters may have a pressure switch. Call us with any questions about your hot tub heater.

"The part arrived within one and a half business days, the price you quoted me included shipping and there were no hidden charges, and you were available to answer my installation questions.
Did I mention that you were less than half the price of the other two hot tub dealers I contacted?
Thank you for everything."
