Anchor to Specifications and Description


Every season is pool season when you’ve got a gas-powered heating system. Warm up your water with the Hayward Universal Natural Gas Pool Heater and you’ll get that summer-perfect temperature all-year-long. Gas power gives you full control over your pool no matter what the weather’s like. The Hayward Heater hooks up to your natural gas line, pulls in water, and uses clean-burning energy to heat it through. That warmer water gets pumped back into your pool, circulates around, and brings it all up to the level you want. Skip the toe-dip test and dive right in. Nothing turns a long day into a good day like kicking back in your home pool or spa. The sooner you can start relaxing the better. That’s why the Hayward Natural Gas Pool Heater is designed to be as quick and easy to use as possible. It starts heating the water immediately and its 500,000 BTU input gets the whole pool to your temperature of choice faster with a state-of-the-art heat exchanger. Once you find that perfect warmth, the Hayward stays there. This heating system’s L.E.D. digital control panel gives instant temperature readouts, diagnostics, and electronic “lock-out” of the temperature set-point. Hayward is the smart choice for pool heating. Its forced-draft system moves air constantly through the combustion chamber at a precise flow rate. That eliminates any problems wind and other weather issues can create in other models. This heater is an eco-friendly way to improve your pool, with reduced emissions. The Hayward features a superior hydraulic design that keeps up with tons of use and is easier to maintain. All the control you get with an indoor pool can be brought outside. Outfit your backyard paradise with the Hayward Natural Gas Pool Heater and the weather will never stop you from soaking it up.
