A pump is utilized to transfer heat from the collectors to the water to be used, which is stored in a remote location away from the collector. This is also commonly known as a split tank system. The best tanks to use in these active systems have built-in copper heat exchanger coils so that the heat can be transferred from the working fluid which passes through the collectors and into the water which is in the tank without the water or working fluid mixing together.
One advantage of active solar water heaters is that they can store the hot water anywhere, even far away from the actual collectors which receive the sunlight. This allows for strategic placing of the tank close to where the water will be used so that it will not take long for hot water flow from the tap.
Winter Resistant
Use of non-toxic propylene glycol antifreeze makes the closed-loop solar water heater system winter/freeze resistant when used in conjunction with a water storage tank with a built-in heat exchanger.The heat pipes in tubular solar collectors contain a proprietory fluid for rapid heat transfer to the manifold. The Duda Solar standard solar collector heat pipes offer general resistance to freezing in cold weather. It is acceptable for the collector to experience intermediate drops below the rated low temperature since the manifold is insulated well and the tubes are protected by a vacuum. However, climates which regularly experience extreme cold weather may require heat pipes designed for the extreme temperatures based on the chart below.
