The Raypak 017705 B-R207A-EN-C #26 Low NOx ASME Digital Natural Gas Pool & Spa Heater is the compact entry point into Raypak's commercial Low NOx platform, delivering a 199,500 BTU input through an all-copper fin tube heat exchanger and heavy-duty bronze headers engineered to ASME pressure vessel standards. Certified for Low NOx emissions compliance and rated for elevations from 0 to 5,000 feet above sea level, it is well suited for smaller hotels, HOAs, spas, and demanding residential pools that need commercial-grade construction in a smaller footprint.

Built with Raypak's rugged PolyTuf powder-coated galvanized steel cabinet, the B-R207A-EN-C #26 is designed to withstand harsh outdoor environments while providing years of dependable service. Its single-piece extruded copper fin tube heat exchanger and porcelainized bronze headers resist corrosion from aggressive water chemistry, while stainless steel tube sheets keep waterways non-ferrous. Raypak's patent-pending ProTek Shield module adds an extra layer of corrosion protection, and the wind-resistant natural draft design keeps the unit firing reliably even in exposed outdoor installations. It is also suitable for chlorinated and saltwater pools.

Digital controls with on-demand pilot ignition make setup, diagnostics, and daily operation simple, while the built-in Unitherm Governor automatically regulates water flow to keep the heat exchanger above 105°F and minimize condensation damage. The heater is ASME pressure vessel certified and meets ANSI Z21.56, SCAQMD Rule 1146.2, and SJAPCD Rule 4308 Low NOx emissions standards for use in strict air-quality regions.
