ProgressivTube® - How Does It Work?The ProgressivTube Solar Water Heater works simply on
The collector/storage tank of the ProgressivTube® absorbs solar radiation through its selective surface coating which raises the temperature of the water stored in the collector. It is well insulated with closed cell foam and the unit is double glazed for increased heat retention. The eight copper tubes are welded into a series flow pattern so that the top of the lower tube feeds the bottom of the next tube. This allows the ProgressivTube® to contain the colder replacement water in the lower tubes where it is heated by the sun as it flows from one tube to the next.
Each time hot water is used, the ProgressivTube’s innovative design eliminates the cooling down of the remaining heated water that normally occurs in other types of batch heaters. Not only does this design ensure the delivery of the hottest water, but is also provides more hot water at a higher temperature and with a faster recovery time than solar systems of similar capacity. |

sunlight and your local water pressure. There is no electrical energy needed to make it function. Once The system has been filled, it will operate on pressure or flow rates that are normal to your household.
