## Customer Reviews

### ⭐⭐⭐⭐⭐ Great Replacement
*by J***H on January 10, 2024*

My previous water heater in my Catilina 42 was tired and leaky. Replaced with this Whale model and back working like a champ!

### ⭐⭐⭐⭐⭐ Whale is an Atwood product
*by D***. on May 21, 2020*

Seems great, switched over, hokeboattern different, but not too bad, was suprised to learn whale is part of Atwood. There is nothing difficult to changing these out, unless your getting old like me and bending and stretching into the depths of hidden places where items such as this is located. Overall a great transition

### ⭐⭐⭐⭐⭐ Replaced a frozen one, this is better
*by C***O on October 15, 2024*

Same as Attwood, once installed, it will heat to very hot in just 90 minutes on 110vac. Engine heat exchanger isn’t nearly as quick to heat, so plug it in an hour or so before you depart. Keeps it hot for less than 24 hrs.
