Hayward Gas Pool HEaters - Highly recommended


Hayward Gas Pool Heaters Repairs, Service and Sales

Hayward is a high-end, USA company that has been making pool equipment for decades. They have been making gas heaters for many years, with some of the best pool heaters ever made. These come with a very simple Warranty that covers the entire heater, rather than many others that break the warranties down into various parts, and then have confusion pro-rata rates. 

Basic Description

The Universal H-Series are energy efficient, high performance heaters which feature a rust-resistant water path, polymer header assembly and a rapid-heat combustion chamber. They are easy to install and maintain, thanks to their low profile, lightweight and CPVC plumbing capabilities.

Universal 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.

Cupro Nickel Heat Exchanger and Low-Flow Bypass

 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.
