PAGE 6 3 1 Water from Pump Filter (Common Port) to sunCOIL 3. The most expensive pieces are the 2" ABS sections and the PVC pool fittings. All sizes of the solar pool panels come backed by a Limited Lifetime Warranty, ensuring worry-free solar pool heating. Every gallon of water that evaporates from a pool takes with it 6000 BTU's of heat in the process - and a typical uncovered pool loses 1 to 1 inches of water a week through evaporation. Pentair Heater Minimum Flow Rates, MT175 - 20 GPM, MT200 - 20 GPM, MT250 - 25 GPM, MT300 - 30 GPM, MT400 - 40 GPM, Jandy Heater Minimum Flow Rates, JXI200 - 30 GPM, JXI260 - 30 GPM, JXI400 - 30 GPM, You should reference your pool heater owners manual or manufacturer directly for accurate information about your heater make and model. Brand: Intex. Adding collector square footage also lengthens the swimming season. To determine temperature rise, subtract the incoming water temperature from the desired output temperature. The highest efficiency solar panels on the market today can reach almost 23 percent efficiency. Heater are only between 60% and 80% efficient, and the efficiency is lower at lower flow rates, so this isn't really true. 3,316 ratings. Basically, the surface area of your solar collector should equal 50%-100% of the surface area of your pool. As with every heater there is a desired temperature rise. Once you reach these flow rates, additional flow results in small marginal increases in performance, and the additional cost of water pumping becomes uneconomical. Heat pumps have a COP (Coefficient of Performance) of 5-6, which means that they transfer 5 to 6 units of heat from the air to your pool, during normal operation. If the bottom of solar is 20 feet below the top of the pool then the pressure is too high for a solar pool heater regardless of the flow condition which can only serve to increase that pressure. Next in line are multiple valves directing water flow to the pool or spa jets or the waterfall/fountain fixture. According to Swim University's "Three Quarters Rule," you'll need enough solar collectors to cover about three quarters of the surface of your pool. For example, a standard pool size is 15 X 30 feet, or 450 square feet. 20,000 (gallons) / 2400 (gallons per hour) = 8.3 hours. Efic = (Heat to Pool) / (Solar Radiation Incident on Collector) The Heat to Pool was calculated as: Heat to Pool = (Tcolout - Tcolin) (Flow Rate) (specific heat of water) BTU/hr Where Tcolout is the collector outlet temperature, Tcolin is the collector inlet temperature, and flow rate is the water flow rate in lbs per hour. GAME 4714 SolarPRO For Intex, 7. . To reduce flow rates, install low-flow water fixtures. For this example, let's say you have a 20,000 gallon pool and the pool pump has a GPM rating of 40. the ideal temperature for pool heating. Assuming the same swimming pool uses a 300 ft2 cartridge filter of 81 GPM maximum flow rate and a 2.0-inch plumbing system of 73 GPM maximum flow rate, take the lower value of these ranges. Larger pools may require additional paneling. Flow rate - A greater flow rate will increase the capability of the exchanger to transfer the heat, but a greater flow rate also means greater mass, which can make it more difficult for the energy to be removed as well as increasing velocity and pressure loss. For a 20 by 40 foot pool, an inch of water amounts to 500 gallons - roughly, a heat loss of more than 30 therms every seven days. SunQuest Solar Pool Heater, 6.
