H-Series MilliVolt heaters feature a rust-resistant water path with polymer header assembly, and a rapid-heat combustion chamber. They are easy to install and maintain.
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-chlorinated pools.
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.
