Pentair Max-E-Therm® Liquid Propane Gas Pool & Spa Heater 200K BTU

The Pentair Max-E-Therm® 200,000 BTU Liquid Propane (LP) Heater is a high-performance heating solution specifically designed for small to mid-sized pools and spas where natural gas is unavailable. This model stands out for its specialized pre-mixed combustion system, which precisely balances the propane-to-air ratio to deliver faster heat-up times and lower emissions, comfortably meeting "Low NOx" standards. The unit is encased in a signature matte-black housing made from Dura-Glas™, a reinforced, rust-proof composite resin that is impervious to UV damage, salt air, and pool chemicals. Internally, it features a high-quality copper heat exchanger for maximum thermal transfer efficiency, alongside a user-friendly digital control panel that provides exact temperature settings and dual thermostats for pool and spa combinations. The compact design allows for easy installation on crowded equipment pads, while the advanced self-diagnostic features ensure maintenance remains straightforward. Despite its streamlined profile, the unit is constructed with a heavy-duty firebox and industrial-grade internal components. The Pentair Max-E-Therm 200K BTU Liquid Propane Heater weighs approximately 138 pounds, providing a rugged, efficient, and reliable heating heart for modern aquatic environments.
