H2501-Hayward 250K BTU MV-NG (OBSOLETE)

Although designed for budget-conscious applications, Hayward H-Series Millivolt heaters deliver uncompromising performance and economy. A standing pilot ignition system ensures reliable lighting, and – like all H-Series heaters – they feature a Finn Plate heat exchanger and Fire Tile combustion chamber.

Features on all millivolt heaters include rust-resistant water path with polymer header assembly and a rapid-heat combustion chamber. They are easy to install and maintain, thanks to its low profile, lightweight and CPVC plumbing capabilities

H-Series 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
