Heater Assembly, 1.0/4.0 KW, Sundance / Jacuzzi, LX BLB 825, 15"

4.0 KW Flo-Thru heater with 2" unions specifically for Sundance and Jacuzzi spas that utilize the Balboa control systems. This model heater has a port for the pressure switch which is used on most models from 2018-2020. The heater also has a plate on the rear for the hi-limit sensor.

Please Note: Models made after 9/7/2020 use a flow switch in the plumbing and at times a plug was installed into the pressure switch port. That plug can be moved over to your new heater w. some teflon tape or thread sealant. We recommend verifying that your model has the plug if you don't have a pressure switch. If not you will need to order this too: Heater Tube Threaded Plug, 1/8"mpt, Plastic
