Hayward Universal HC-Series 275K BTU Dual-Fuel Heater
The Hayward HDF275 is the next generation of pool heating, combining a high-output 275,000 BTU capacity with the industry’s most compact design. Specifically engineered for pools up to 25,000 gallons, the HC-Series is the ultimate solution for tight equipment pads where performance cannot be compromised.
The "New Standard" in Pool Heating:
-
Dual-Fuel Technology: Unlike traditional heaters, the H275 is designed for easy in-field conversion between Natural Gas and Propane. The "easy-out" mixing orifice makes switching fuel sources fast and simple, providing ultimate flexibility for any backyard setup.
-
Smallest Footprint in Its Class: With a tiny 21" x 21" footprint and zero wall clearance requirements, the H275 fits into spaces other heaters can't. It’s the perfect "drop-in" replacement for older, bulkier units.
-
Top-Access Serviceability: No more kneeling or removing side panels. The reversible top provides easy access to the gas shutoff, voltage selection, and internal components from the top of the unit.
-
Superior Durability: Features a standard Cupro-Nickel heat exchanger, providing maximum protection against corrosion from saltwater systems and chemical wear.
-
Maximum Efficiency: Boasts an impressive 84% thermal efficiency rating, the highest in its class, ensuring your pool stays warm while keeping your utility bills low.
