Universal HC Series - Dual Fuel 400k BTU



The industry’s smallest footprint heater allows replacement of almost any heater in an existing pad with the efficient reliability of the new Universal HC Series dual-fuel technology heater from Hayward®.


Universal HC Series dual-fuel technology gas heaters are uniquely engineered for use with Hayward® plumbing adapters, making them an easy drop-in replacement for other heater brands.
