Hayward H Series (Universal H Series)

The Hayward Universal H Series is a series of pool and spa heaters ranging from 150K to 500K BTU/hr with versions for either natural gas or propane. The key benefit of these heaters is their energy efficiency and low NOx emission levels which comply with all current California and Texas air quality emission standards.

The Hayward Universal H-Series heaters feature an industry leading 83%-84% thermal efficiency and this plus the low NOx emissions make these heaters about as environmentally friendly as a gas heater can be (unless you pay considerably more). This energy efficiency is achieved through the use of an insulated fire tile combustion chamber which minimizes heat loss and maximizes the heat output for every BTU used.

These heaters also save energy through their industry leading hydraulic performance which reduces the time the pump needs to be running.

  • Exclusive Silicon Nitride ignition system – provides dependable lighting and reliable operation.
  • Digital LED Control Panel – which makes it easy to see the water temperature and  monitor heater performance.
  • Dual Voltage – Can be installed with a 110 or 220 volt electricity supply.
