When solar collectors are rated for efficiency they are tested with a wind speed of less than five miles per hour with the sun directly above the solar collector surface. In the real world the wind often blows at more than five miles per hour and the sun is directly above the collector surface for only an instant each day at solar noon. For the rest of the day the sun is at various angles to the surface. Therefore, the rating does not always predict the amount of the sun’s energy the solar collector will actually absorb while it is heating your pool. Harter Industries products will send more heat to your pool at any hour of the day because they are designed to make better use of the available solar energy.
HI-Deluxe, Hi-Temp and EZ Heat solar collectors use the proven tube-on-fin solar collector that works all day to absorb more of the available solar energy and send more heat to your pool.
The curved tube surface exposed to the sun’s energy presents a more constant surface area to the sun during the day as the sun’s angle to the solar collector surface changes than does a flat or nearly flat surface.
The space between the tubes forms a heat trap. Some of the solar energy falling on the fins and tubes re-radiates to the sides of the tubes and forms a high temperature area that is protected from the wind passing over the surface. This increases the amount of solar energy absorbed by the tubes, sending more heat into the pool water. That gives us a great advantage over solar collectors with separate exposed tubes where the wind passing between them wipes the warm air from their surfaces, cooling them.
The more water that passes through each square foot of solar collector each day , the more solar energy it will collect and the better it will heat your pool. When a laboratory is testing a solar collector to determine its heating performance rating it forces a predetermined amount of water through each square foot of collector surface.
Some solar collectors have built in restrictions to water flow that prevent the amount of water that they are rated under from flowing though them when they are connected to a pool filter system. That means that they will not heat your pool as well as their rating.
All Harter Industries Solar Collectors have wide-open straight-though flow passages that let more water flow through them. That sends more heat to your pool each day.
Captures the most solar energy: Our proven tube-on-fin design sends 70 to 94 percent of the available solar energy to the pool water under normal operating conditions.
Most durable: Our headers are molded to the extruded absorber surface in a 450-ton injection-molding machine, forming a permanent, leak-proof bond. Our unique tube-on-fin absorber freely expands and contracts with temperature changes, relieving the stresses that cause other solar collectors to deteriorate with age.
Proven materials: HI-Deluxe is made from a special grade of polypropylene that has demonstrated consistently high reliability in solar pool heating collectors for over 23 years, in all climates.
Better flow: Generous two-inch inside diameter headers and straight-through water flow in the absorber tubes, improves water flow. Better flow raises solar collector performance and assures maximum pool filtration.
Better appearance: Our injection molding process smoothly joins the header and absorber, assuring consistently superior workmanship. Installed solar collectors are close-coupled, minimizing space between absorbers. The narrower gap improves the appearance of the array and fits more solar collector area into less space.
EZ Mount: Our exclusive EZ Mount system makes HI-Deluxe's installation fast, safe and durable. Built-in sealing pockets assure sealed anchor points. EZ Mount spaces the headers away from the roof. This protective design feature, combined with the tube-on-fin contour, eliminates the need for costly substrate.
Quality controls: Each HI-Deluxe solar collector is inspected at every production step. The completed solar collector is subjected to a pressure test of 100 pounds per square inch and undergoes a thorough final inspection before it is shipped. HI-Deluxe is made in the U.S.A. with care and pride. This outstanding quality makes it possible for us to give you a lifetime limited warranty.
