Balboa Water Group50067 4.0-Kilo watt Spa Heater with Pressure Switch, 15-Inch

Fit perfectly, works great, easy fix

came with gaskets now i have an extra set .... works great HOT TUB UP AND RUNNING AGAIN! ez change out took a few extra days to come

Had to replace out heater component with this and it has been heating our spa better than the previous one. After installed, it took from 8 hours to 5-6 hours for a 20 degree adjustment. Still working great

Works great..
