Pentair MasterTemp® Low NOx Pool Heaters

Ultra-high performance in a compact, quiet, and eco-friendly design

MasterTemp Heaters offer all the efficiency, convenience, and reliability features you want in a pool heater, plus a lot more fast heat-up, compact design, super quiet operation, easy to use, and eco-friendly. The MasterTemp is constructed of a rust-proof composite material which is highly resistant to the elements.

An Eco Select Choice: MasterTemp Heaters offer best-in-class energy efficiency. Plus, they are certified for low NOx emissions, making them eco-friendly favorites.

MasterTemp’s easy-to-read controls make system operation and monitoring simple. Pool and spa temperatures can be pre-set and controlled with the push of a button. A digital display indicates the water temperature, and five LED lights give you system status and let you know if the heater needs service.

The MasterTemp swimming pool heater utilizes PMG combustion technology which requires no outdoor draft hood to operate. The result is the highest efficiency (84%) pool heater in its class, while keeping NOx emissions to a minimum. That means less time waiting for your pool or spa to warm up, and more time enjoying it.

The Pentair MasterTemp is also available as a Heavy-duty unit equipped with a cupro-nickel heat exchanger which stands up to harsher applications, such as low pH, high flow or heavy use, such as you would find in a health club spa or rental property. ASME versions are also available for commercial use.
