      Obviously, heating your pool provides you with comfortable swimming water but it also extends your swimming season. The end of summer can be a downer as you prepare to close your pool for another winter season; but, with Hayward natural gas pool heaters you can continue swimming well into the fall and even the winter in some climates. The Hayward H Series Pool heaters utilize the most advanced heating technology so you can maintain the perfect comfort level for your pool.

      There are few pool supply manufacturers that can compare with the quality, durability, and efficiency of Hayward products and this is certainly true of Hayward natural gas pool heaters as well. We all love to swim and the fact is we don’t want to have to say goodbye to the evening dips in the pool just because the weather starts to go sour. Hayward H-Series natural gas pool heaters stand up to poor weather so you can enjoy your pool even in the fall.

      Heater Information
      ADVANCING THE STATE-OF-THE-ART.

      The Hayward® H-Series induced draft heater incorporates the most advanced heating technology to provide luxuriating comfort, energy-efficient operation and long-lasting dependability. When you select the patent-pending H-Series, you'll turn up the heat in confidence with features that includes a rust-resistant water path, a rapid-heat combustion chamber and a direct spark ignition system.

      Plus, a state-of-the art induced draft system provides a completely controlled heating environment in the combustion chamber, making the H-Series impervious to any high wind occurrences.

      You will be equally impressed with the appearance and user-friendliness of the H-Series heater as you are with its performance. Low-profile in design, the H-Series offers such aesthetic attributes as a contoured cabinet styling and a control panel that features LED diagnostic system. Which makes owning a Hayward® H-Series heater as enjoyable to your visual and tactile senses as it is to your pool and spa.

      INDUCED DRAFT FOR PRECISE AIR FLOW.
      Hayward® H-Series heaters feature 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 effect heating performance, such as high wind conditions, are eliminated-without having to install a high wind stack.

      ULTIMATE DURABILITY.
      Hayward® H-Series heaters are the only heaters that employ a rust-resistant water path. Unlike other models that use a heavy cast iron or costly bronze assembly, H-Series headers are manufactured from a modern injection-molded polymer process. The benefits are lighter weight for easier installation and rust-free durability for extended performance.

      THE PERFECT TEMPERATURE.
      The H-Series features a high-performance flow that continually monitors and regulates water flow, maintaining internal temperature at a constant level. Specifically designed to deliver maximum efficiency, it assures that fuel use is more efficient; and comfortable temperatures automatically maintained.

      GEOMETRY THAT ADDS UP TO TOTAL COMFORT.
      The jet-ported burner system evenly distributes incoming fuel to precise geometric openings on each burner tube. This assured that each flame is in the most fuel-efficient position on the tube assembly. The result is superior comfort at all times. Constructed of tough, durable Eugenox, a proprietary steel alloy, H-Series burners can be removed individually or as a complete unit for easy maintenance and cleaning.

      GET THE MOST OUT OF EACH BTU.
      The patent-pending one-inch-thick Fire Tile® insulated combustion chamber creates an interlocking shell that's measurably stronger, with improved heat-retention capabilities. Unlike older firebrick, Fire Tile® holds the heat in and doesn't allow it to escape, providing up to 83% thermal efficiency.

      CONNECT WITH CPVC.
      The H-Series' ability to cool down quickly after heating your pool or spa to the desired temperature allows for the use of CPVC plumbing connections. This exclusive Hayward® capability not only eliminates the need for expensive heat sinks and fireman switches, but also reduces time and cost at installation. As an added benefit, a CPVC connector kit is included with ever H-Series heater.

      SELECTING THE H-SERIES THAT'S RIGHT FOR YOU.
      H-Series heaters incorporate a LED diagnostic system that provides for quick and accurate pinpointing of component performance, for simplified servicing. They are also "remote-ready," which allows timer systems to be hard-wired directly to your H-Series heater. All H-Series heaters employ a changeable temperature limiter switch for added safety and convenience.

      EXCELLENCE BACKED BY A HERITAGE OF LEADERSHIP.
      When you choose H-Series, you not only select superb technology, you also benefit from the knowledge and commitment that the industry's leading manufacturer can provide. Only Hayward® offers pool and spa owners the compatibility of The total Hayward® System... a comprehensive, coordinated family of quality designed and precision crafted recirculation products.

      GRADUATE TO A HIGHER DEGREE OF COMFORT.
      Extend the warmth of your hospitality with the addition of a Hayward® H-Series high-performance heater. And transform the element of water into an element of pure enjoyment.

      H-Series heaters feature water connections that are fully compatible with preexisting installations.



      What Size Do I Need For My Pool?

      Step 1.
      Use charts below to determine your pool's surface area in square feet:

      FREE FORM POOL FORMULA

      Area = (A + B) x L x .45
      Example:
      A = 15 ft.
      B = 20 ft.
      L = 35 ft.
      Area = 551.25 ft.


      ROUND POOL FORMULA

      Area = R x R x 3.14
      Example:
      R = 12 ft. (R = radius is 1/2 of the diameter of the pool)
      Area = 452.16 ft.


      RECTANGULAR POOL FORMULA

      Area = L x W
      L = 32 ft.
      W = 16 ft.
      Area = 576 ft.

      Step 2.
      Locate in the table below, the surface area equal to or just greater than your pools surface area, read to the left and select the appropriate H-Series model.
      Note: For indoor pool installations, divide the pool's surface area by 3.

      Model Surface Area
      H400ID Series 1200
      H250ID Series 750

      Table is based on a 30º F temperature rise, 3 1/2 MPH average wind velocity and elevation of up to 2,000 feet above sea level.


      What Size Do I Need For My Spa?

      Step 1.
      Determine your spa capacity in gallons (surface area x average depth x 7 1/2.)

      Step 2.
      The reference table (below) lists the time required in minutes to raise the temperature of your spa/hot tub by 30º F. Locate in the table below your spa/hot tub size in gallons. Select the desired time to raise your spa/hot tub temperature 30º F, read to the left and select the appropriate H-Series model.

      Model
      (below)
      Spa size in gallons
      200 300 400 500 600 700 800 900 1000
      Minutes to raise spa temperature 30º F
      H400ID Series 9 14 19 23 28 33 37 42 47
      H250ID Series 15 22 30 37 45 52 60 67 75

      This guide can be adjusted for other temperature rises. For example, if you desire a 15º F increase in temperature, simply divide the time for 30º F rise by the ratio of 30/15=2.

      Note: Heat losses and/or heat absorbed by spa walls or other objects will add to the heat-up time.
      Spa sizing is based on an insulated and covered spa. Always cover your spa or hot tub when not in use to minimize heat loss and evaporation.
