Great customer service
Pentair's customer service is excellent. I had some challenges during the initial installation and the customer service team worked with me over the phone and with a local representative to get everything squared away quickly [This review was collected as part of a promotion.]

Pentair 400K BTU Heater
Replaced my 400,000 BTU Ray Pak heater which had massive interior rust issues. The Pentair unit is largely plastic cinstruction and the weight is considerably lighter making installation in tight spaces much easier, about 50% less. [This review was collected as part of a promotion.]
