JR Series Hydromassage Bathtub Heater (I Type) 115V/230V (1000W-3000W)

JR Series Hydromassage Bathtub Heater (I Type) for Spa & Whirlpool Systems

The JR Series Hydromassage Bathtub Heater (I Type) is designed as an inline electric heating element for whirlpool bathtubs, spa pools, hot tubs, and hydromassage systems. It keeps the bathing water at a comfortable temperature so users can enjoy longer massage sessions without adding fresh hot water. This I Type variant is engineered for flexible installation in standard bathtub plumbing layouts.

Operating on either 115V or 230V, the JR series with the I Type configuration is available in four power ratings—1000W, 1500W, 2000W, and 3000W—to match standard single tubs, single big tubs, standard double tubs, and spa-sized pools respectively. Current draw ranges from 4.3 A to 17.5 A depending on voltage and power, while the compact 255 mm body length keeps installation flexible in tight equipment compartments.
