ProgressivTube®
Works in Every Climate

For more than 20 years, ProgressivTube solar water heating systems have earned the reputation of exceptional value in tropical and temperate climates worldwide. Now, northern climate homeowners and businesses can enjoy the many benefits this system has to offer.

The ProgressivTube Seasonal Solar System™ is designed to supply a significant percent of daily hot water heating requirements during spring, summer and fall. In late fall through early spring, the ProgressivTube is drained and isolated to prevent freezing. In the event of an unexpected freeze condition, the built-in Eaton Dole Freeze Valve (request this option) will provide limited protection.

During the cold, overcast winter months, the existing conventional heating system supplies hot water.

ProgressivTube Outperforms Other Solar Systems

Compared to other solar systems, ProgressivTube yields an excellent ROI in many installations. When the initial lower installed cost of the ProgressivTube system is considered, coupled with no maintenance or operational costs, the ProgressivTube offers exceptional value over other solar systems.

The best suited solar water heater systems for northern climates are the Active Closed-Loop and the Passive Systems. Research has shown that the Passive ProgressivTube is the most cost effective system even in cold climates:

ProgressivTube
● Purchase price and cost of maintenance is lower
● Has the greatest return on your investment
● Reduce hot water energy costs up to 100%

*Your geographical location determines the amount of months that the ProgressivTube system will operate in your area. In warmer climates, the ProgressivTube will operate all year round and will meet nearly 100% of a household's hot water needs. (Units must be drained when sustained freezing conditions occur.)

Monthly Savings Comparison

The chart below demonstrates average typical savings, as in zone 9 where the ProgressivTube system operates for 9 months and the system is turned off during the coldest 3 months of the year.

The Active-Closed Loop system can operate in the coldest weather months, however, the efficiency is greatly reduced.

Payback Comparison

An Active-Closed Loop solar water heater will cost you $4,000 and will save you about $600 per year. Your investment will be completely paid back by operating savings in approximately 6-1/2 years

A Passive ProgressivTube system will cost you approximately $2,000 and will save you about $500 per year. Your investment will be completely paid back by operating savings in approximately 4 years.
