Hayward Universal H-Series Heaters

Hayward Universal H-Series heaters are widely used for residential pools and spas and are available in multiple BTU sizes. Common models include 250,000 BTU and 400,000 BTU configurations, with selected ASME versions for commercial or code-specific applications.

Hayward OmniX Heater Options

Newer Hayward heater packages may include OmniX-connected control capability. These models can be useful when building a coordinated Hayward equipment system with compatible pumps and automation.

How to Choose the Right Hayward Heater

Heater selection depends on pool and spa volume, desired temperature rise, climate, fuel type, available gas-line capacity, electrical service, plumbing size, altitude, venting, indoor or outdoor installation, and local code requirements. A larger BTU rating can heat faster, but the heater still must be matched to the property's gas supply and installation conditions.

Natural Gas, Propane & Dual-Fuel

Always verify the actual fuel source before ordering. Natural-gas and propane models use different fuel components, and conversion is only appropriate when the manufacturer provides an approved kit or procedure for the exact model. Selected Hayward HC Series models are designed for dual-fuel flexibility, but model-specific requirements still apply.

Hayward ASME Heaters

Hotels, apartments, community pools, fitness facilities, schools, and other commercial installations may require ASME-certified heating equipment. Pool Supply Depot carries selected Hayward ASME models and can help source commercial equipment for projects that require code-specific configurations.
