With the Universal HC Series Heater, Big Innovation Comes in the Industry's Smallest Footprint

Pound for pound, the Hayward® Universal HC Series Heater is jam-packed with more innovation than anything else on the market. As the industry's smallest footprint heater**—engineered for both superior performance and servicer ease—UHC Series is the perfect choice for smaller pool pads and tight backyard spaces. All in all, the advanced dual-fuel heater just fits better—onto servicer trucks, into pool pads and within consumer budgets.

Maximum performance, minimum size

On first glance of the unit, it's tough to miss the Universal HC Series' compact size. But when it comes to the dramatic footprint reduction, the smaller physical frame is only part of the equation.

The other part? Zero wall clearance. Yep, you read that right: zero.

The Universal HC Series is equipped with a unique vertical discharge system that safely eliminates heat—even while the unit is placed directly against a wall, fence or other pad unit. While other heaters waste valuable pad space on as much as a foot of wall clearance, UHC Series can operate at its full 400k BTU/hr. capacity without any clearance at all.

Big picture? Between the smaller product dimensions and the complete lack of wall clearance, the UHC Series requires only 590 square inches of total pad space. Compare that to the next smallest heater's footprint (928 square inches), and it's not hard to see why UHC Series' small size is cause for big excitement.

Clever design with a twist

The Universal HC Series' smaller size is due in large part to clever usage of internal space. This do-more-with-less philosophy is apparent in just about every corner of the heater's interior, but let's look at just two of them.

First, UHC Series is built to run on either liquid propane or natural gas, all from one easy-out mixing orifice. And switching fuel types on the fly is never more difficult than a simple quarter-turn twist of the valve. The versatile design makes in-field propane conversion easier than ever for servicers, and it also helps dealers and installers simplify their catalog with just one do-it-all heater.

Second, access to all of UHC Series' high-use internal components (gas shutoff, voltage selection, plumbing direction, etc.) have been moved from the side of the unit to the top. And while this is certainly significant in terms of further reducing the product size, the auxiliary benefit is far more exciting: a top-mounted panel eliminates the need for crouching or kneeling in order to service the heater.

Made for the trade

In addition to its size and fuel flexibility, many other UHC Series features have been specifically engineered to provide substantial quality-of-life improvements for members of the trade. Here's a quick rundown of some of the other features that make Universal HC Series the ideal heater choice for installers and servicers alike:

  • A patented butterfly bypass valve that enables flow rates of up to 125 GPM—without requiring any additional accessories
  • Exclusive plumbing adapters that eliminate the need to cut the pipes, even when replacing third-party heaters
  • A premium cupro nickel heat exchanger that extends heater performance by resisting corrosion and natural wear

And, of course, it's also great for consumers—delivering superior heating performance and low-emission efficiency. But after seeing everything else that Universal HC Series has in its arsenal, standout capability shouldn't as a surprise. All in all, there's a whole lot to love with this advanced dual-heater. It's one giant leap for heater innovation, and one ultra-small unit footprint.
