The Standard Plunge comes with a 1/4hp chiller. This is the model we suggest customers to put indoors as it is quieter and for those that live in milder climates and want the plunge outdoors. The standard chiller will have trouble keeping the Plunge blow 50 degrees in hotter climates.
Plunge Pro & XL Models
The Plunge Pro and XL comes with a 1hp chiller. This model is designed for people that are putting the Plunge outside in higher heat and need the extra cooling power. The pro chiller will keep your plunge at the coldest temps even in the hottest part of summer.
We recommend that residential customers do not put the Pro, or XL indoors due to the noise of the chiller.
