Hayward H-Series Gas Pool Heaters

The Hayward H-Series gas pool heater is a high-tech option for pool owners looking for a powerful, efficient, and reliable pool heating unit. The H-Series can raise the temperature of an 800 gallon pool by 30 degrees in less than an hour! Even for smaller pools, the advanced features of this unit can extend your swimming season for months without any hassle or stress. They come in several sizes with different types of ignition systems and can run on natural gas or propane, with options for Low NOx models as well.

Power and Efficiency

Each H-Series unit is equipped with a rapid-heat combustion chamber and is highly rated for heat generation and transference. Made from insulated Fire Tile material, the combustion chamber traps all the heat generated and utilizes it for your pool, making for an extremely energy-efficient process. Each unit is equipped with a forced draft system to channel a constant stream of air through the combustion chamber and prevent weather conditions from affecting heating performance.


These gas pool heaters are built to last. Stainless steel burners and specially-engineered heat exchangers are designed to resist corrosion, and each unit has a rust-resistant water path. The Direct-Spark ignition system is one of the most reliable designs on the market and can be operated with the touch of a button. Users can also change their system settings at any time with the LED control panel. The interface is easy to use and makes it simple to monitor the performance of your pool heater.
