Manufacturer's Warranty Period:
All of our solar products come with a manufacturer's warranty. A manufacturer warranty covers materials defective due to the manufacturing process. If a manufacturing defect is discovered during the manufacturer's warranty period, the item may be returned to Duda Energy for repair or a replacement. Only materials found defective due to manufacturing will be replaced under the warranty. The warranty does not cover natural phenomenons such as corrosion.
The manufacturer's warranty period does not designate the expected lifetime for a material, unit or device. It only applies a limited time period in which defects due to manufacturing may be eligible for a claim.
Solar Collector Warranty Period: 3 Years
Stainless Steel Tank Warranty Period: 2 Years
Electrical Heating Element Warranty Period: 1 Year
Controller Warranty Period: 1 Year

Some of the many uses:
Heat domestic home water
Solar Radiant home heating
Radiant floor heating
Pool & jacuzzi heating (We also have unpressurized collectors specifically for this)
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.
