Pentair MasterTemp® Liquid Propane High Performance Heater 250K BTU

The Pentair MasterTemp® 250,000 BTU Liquid Propane (LP) Heater is a high-efficiency heating powerhouse designed to deliver rapid warmth to residential pools and spas where natural gas is unavailable. This model is renowned for its compact, "best-in-class" footprint, which allows it to fit easily into tight equipment pads while outperforming larger, traditional heaters. It features a sophisticated pre-mixed combustion system that optimizes the propane-to-air ratio, ensuring faster heat-up times and lower emissions that meet "Low NOx" standards. The exterior is constructed from a rugged, rust-proof composite resin that resists UV damage and chemical corrosion, while the internal cupro-nickel heat exchanger provides a robust defense against fluctuating water chemistry. A user-friendly digital display rotates for easy viewing and provides clear temperature readouts and system diagnostics, while integrated safety sensors monitor water pressure and high-limit temperatures. Despite its streamlined profile, the unit is built with a heavy-duty internal firebox and industrial-grade plumbing that give it a solid, professional-grade construction. The Pentair MasterTemp 250K BTU Liquid Propane Heater weighs approximately 120 pounds, providing a reliable, quiet, and powerful heating solution for high-performance aquatic systems.
