A shopper on Mar 31, 2016
BEST ANSWER: Thought that pool supply or Pentair had a chart on their site for above ground or in ground pools.that I used. From memory I got a slightly larger one just to speed up the process. I also have solar panels that help pre heat the water. You can always call Pentair direct. They always seem very help full.
The heater turns on and in 6-10 secs. the temp. goes up and shaking and shuts off. Is the heating unit clogged?
A shopper on Aug 9, 2016

Reliable heater
The electronic display really helps me to understand how to use it. My water heats up quickly so I've saved on my gas bill. Positive outcome from this purchase.
March 7, 2016
High Performance
This is a real plus in my book. Ive been in the pool industry for quite some time and this Pentair heater has a reputation for being one of the best on the market. This product arrived on time and as expected. It puts off a little odor while it primes the heater, but its not that bad, and if youre not right on top of it, you probably wont notice it. So far, it works great and heats FAST best of all.
