Product Description & Reviews
Expansion tanks are essential for solar water heater systems. The Red expansion tank is used for relieving pressure build-up in the closed loop system. This helps keep the pressure consistent and relieve pressure from the piping as the working fluid increases in temperature. Should the solar system go into overheat mode and shut down the circulation pump, the expansion tank is essential for preventing the pressure valve from blowing out the working fluid. The Red Duda Solar expansion tank is fitted with a special high temperature EPDM membrane made in Italy which can withstand the high temperatures of the solar systems. The size of the expansion tank needed depends on the total amount of fluid used in the closed loop (maximum possible volume). Some data regarding common fluid volumes in the solar systems is in the chart below. As an example, a standard 300 liter solar system has a 30 tube collector, 100 feet of 1/2" stainless steel tubing and a 300 liter tank (25m coil) for a total of ~7 liters of fluid volume, requiring at least an 8 Liter expansion tank.

Blue Duda Solar Expansion tanks are constructed with a food grade EPDM diaphragm for potable water applications. These should be used for relieving pressure from building up in the domestic water tank as it heats from the solar loop. Use of an expansion tank helps regulate the pressure so that it does not get too high in the tank and cause water loss due to the T/P valve opening when the pressure of the water exceeds the limit. The difference in water density from cold (4°C) to near boiling
