Passive Solar Water Heaters
PROGRESSIVTUBE® passive solar hot water heaters are self-contained, single unit systems that integrate the solar collector and storage tank. In most applications, it functions as a pre-heater to an instantaneous or conventional water heater.

PROGRESSIVTUBE® solar hot water heaters require only local water pressure and solar radiation to operate. No pumps, controls, mechanical or electrical components are required. Once installed, the system will work automatically. When hot water is used, solar pre-heated water is drawn into the conventional water heater, reducing electrical or gas usage for water heating. The PROGRESSIVTUBE® is among the most efficient solar systems rated by national testing and certification agencies. All PROGRESSIVTUBE® solar hot water systems meet or exceed all applicable national plumbing and building codes. Our systems are virtually maintenance free and feature a twenty-five year design life. Whether your purchase decisions depend on simple pay back, return on investment or life cycle analysis, PROGRESSIVTUBE® solar hot water heating system can exceed your expectations.

PROGRESSIVTUBE® the value leader in solar technology!
How It Works

The all copper collector/storage tank absorbs solar radiation through its selective surface coating by raising the temperature of the water stored in the collector. It is well insulated with closed cell foam and double-glazed for increased heat retention.

The 4” diameter 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 collector 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 innovative design eliminates the cooling down of the remaining heated water that normally occurs in other types of solar hot water heating systems.

Not only does this design ensure the delivery of the hottest water, but it also provides more hot water at a higher temperature and with a faster recovery time than solar systems of similar capacities.

Home Owner Benefits:
Our solar water heaters reduce anywhere from 50% - 90% of your annual hot water heating costs that are typically 20% - 40% of your utility bill. Only A/C and heating is a higher energy cost than hot water heating. Savings of $150 - $300 + each year of your water heating cost is typical for families of 2 - 4. Larger families save even more.
Double your hot water storage capacity - no running out of hot water.
Environmentally friendly PROGRESSIVTUBE® solar water heaters off set utility pollution the equivalent of driving x miles or a forest of x acres.
