Designed specifically for Pools and spas: The MiniMax Plus Pool Heater is designed for fast heat-up, low operating costs, and long life. It's available direct-spark ignition and millivolt versions for propane or natural gas.

Today's heaters from Pentair make extending your pool and spa season, adding to your comfort, and maximizing your backyard enjoyment a suprisingly affordable addition. They heat up fast. They're economical to run and the are built to last for many years. The key to spa heating economy is combustion efficiency...making sure the heat generated is transfered to spa water with as close as 100% efficiency as possible. This requires an optimum combination of combustion chamber design, burner assemblies and materials, heat exchanger and state-of-the-art heater insulation. That's why all Pentair heaters features strong corrosion resistant stainless steel burners, durablebronze headers, and weatherproof powder-coated housings. MiniMax Plus Pool Heater also includes ceramic fiber tile insulation and "intelliggent" controls that sense water temperature and pressure for optimum flow.
