Universal HC Series 400,000 BTU - Dual Fuel
Hayward
SKU: HDF400
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®.
Features
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. The heat exchanger is made from cupro nickel for added reliability, and the easy-out air/gas mixing orifice makes propane conversion fast and simple. The small footprint with zero wall clearance fits in even the most compact equipment pads, while the refined gas controls and remote connectivity provide a simple user experience with added service convenience.
