Pentair 460805 Master Temp(HD) 400K BTU Saltwater Pool Heater

On the hottest days of the summer, your pool can be the perfect refreshment to take a break from the sun. But in the early and late days of the swimming season, there are times when your pool water won't have had time to catch up with the weather. Icy water can be offputting to swimmers, and discourage your family from getting the most out of your swimming season.

If you've been looking for a new heater for your saltwater pool, it is important that you find a model that has been designed to withstand the corrosive power salt. With the new Pentair saltwater heater, you can provide affordable and efficient heating for your saltwater pool without worrying about corrosion or breakdowns.

Why choose the Pentair Saltwater Heater?

If you have a saltwater pool today, or if you've considered making the change in the future, it is important that you find a heater that can stand up to the salinity. Traditional pool heaters can be quickly corroded by saltwater, leaving you with a heater that is damaged beyond repair. This Mastertemp heater by Pentair is a reliable model that is suitable for use in saltwater, or in traditional chlorine pools.

The Pentair saltwater heater is a super-fast performer, allowing you to easily heat your pool or spa when you want to hop in fast. Despite all of its power, the Pentair saltwater heater is also incredibly efficient. The 84% rating exceeds environmental standards, and ensures you can run your pool affordably.

The Pentair saltwater heater has also been built to last. With a rust-proof exterior and corrosion-resistant treatments, you can rely on the Pentair Mastertemp for many years of fast and reliable heating for your pool.
