Description of Hayward H-Series Millivolt Natural Gas Outdoor Heaters: 150,000 to 250,000 BTUs.

Hayward H-Series MilliVolt heaters achieve the ideal swimming pool and spa comfort level. The Hayward H-Series MilliVolt heater features a rust-resistant water path, with polymer header assembly, and a rapid-heat combustion chamber. H-Series heaters are easy to install and maintain, thanks to its low profile, lightweight and CPVC plumbing capabilities.

In addition, Hayward H-Series MilliVolt heaters are all equipped with a Cupro Nickel Heat Exchanger for efficient heating and superior durability. Cupro Nickel provides improved durability and longevity against the damaging effects of erosion that can occur under high-flow conditions, corrosion from occasional pool chemical imbalances, and is ideal for salt-water based pool systems.

For extra protection, the Cupro Nickel material has been coupled with an improved flow rate by-pass control. Together, these added technological improvements ensure that your Hayward heater outperforms and outlasts expectations.

Other Features:

Patented single header V baffle design heat exchangers allow for long life, fast heating and virtually no condensation. All Hayward heat exchangers are now constructed with highly resilient Cupro Nickel for greater durability and longevity.

Rust resistant water path, with injection-molded polymer header, offers improved by-pass control and extended life by providing additional protection from the damaging effects of erosion from high flow conditions.
