Pool & jacuzzi heating (We also have unpressurized collectors specifically for this). 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. Duda Solar Heat Pipe Freeze Resistance Chart.
