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

The Pentair Max-E-Therm® 200,000 BTU Natural Gas Heater is a high-efficiency heating system tailored for small to mid-sized residential pools and spas that require rapid warmth in a compact, durable package. This model is distinguished by its sleek, matte-black enclosure made of Dura-Glas™—a high-density, rust-proof composite resin that is specifically engineered to withstand the harshest outdoor elements, salt air, and corrosive pool chemicals. Utilizing a sophisticated pre-mixed combustion system, the unit optimizes the fuel-to-air ratio to provide faster heat-up times and lower energy costs while maintaining a "Low NOx" certification for environmentally friendly performance. The interior features a heavy-duty copper heat exchanger designed for maximum thermal transfer and a long service life, alongside an intuitive digital control panel that offers precise temperature management and self-diagnostic alerts. Its space-saving design makes it an ideal choice for retrofit installations on crowded equipment pads without sacrificing industrial-grade power. Despite its modern and streamlined aesthetic, the heater is built with a substantial internal firebox and professional-grade plumbing manifolds that provide a solid, rugged construction. The Pentair Max-E-Therm 200K BTU Natural Gas Heater weighs approximately 138 pounds, serving as a powerful, quiet, and ultra-reliable heating solution for modern aquatic environments.
