Hayward pool heaters
Research Hayward Universal H-Series and HeatPro pool heaters with manual-first checks for sizing, fuel, installation and warranty fit. Verify the exact SKU, fuel, voltage, warranty channel and current manual before ordering.
How to compare this lineup
Hayward spans fast-recovery gas heaters and air-source heat pumps, so the product family must match the job before model numbers are compared. For an H-Series quote, verify fuel, input rating, altitude and exchanger configuration. With HeatPro equipment, compare published output and COP at relevant air and water conditions. In both cases, ask which local company can commission and service the exact unit without weakening warranty eligibility.
