Pentair MasterTemp 400k BTU Natural Gas Pool Heater

During the first few weeks of the summer season, it can be difficult to be patient as you wait for your pool to be ready to swim in. When your water is icy cold, the pool can be off putting to even the most avid swimmers, and can shorten your swimming season significantly.

If you love the summer sun, adding a heater to your pool is among the best ways to get more out of the summer season, and enjoy more weeks of swimming each year. With the Pentair Master Temp heater, you can heat your pool reliably and affordably.

Why choose the Pentair Natural Gas Heater?

Pentair is a trusted name in residential pool heating, and has been providing warm and efficient heat for pool owners across North America for years. Pentair goes above and beyond in innovation and design, improving with each iteration of their natural gas heater.

This ensures that your pool heating is affordable, and environmentally friendly. Replacing a pool heater can also be an enormous cost, and Pentair has designed the Master Temp heater to be able to withstand the tough outdoor conditions of your pool.
