Hayward H-Series Low NOx High Performance Heater
The new Hayward H-Series Low NOx Induced Draft Heaters feature a patented Finn Plate™ heat exchanger with Cupro Nickel for constant heat dispersement, state-of-the-art pre-mix burners for environmentally friendly Low NOx outputs, hot surface Silicon Nitride ignition for instant and reliable fire up, and an advanced L.E.D. digital control panel for simple programming of pool temperatures. The Hayward H-Series Low NOx Heater is a smart buy for pool owners.

It also includes an induced draft system that constantly moves air through the combustion chamber at a precise flow rate. As a result, all outside weather variables that can affect the heating performance, such as wind conditions, are eliminated - without having to install a high-wind stack.
