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.

Savings and Return on Investment
|
An average family of four uses 70 gallons of hot water per day at a cost of $480 per year*. The typical Solar Water Heater will save 90% or more of the heating costs, or $432.00 per year.
A typical heater of this size (PT40CN) with installation averages $6,650.00 minus a 30% tax credit; your net cost is $4,655.00.
The tax-free return on this investment would be 9.6% ROI ($482 / $4.655.00)

Reasons for Installing the ProgressivTube
|
- Solar water heating reduces the monthly operating expense of the household.
- Reduced operating expenses give homeowners more cash for discretionary purposes, savings, etc.
- Solar water heaters are the only home appliance that saves money without reducing comfort or convenience.
- Solar water heating is a hedge against higher future energy costs, which are a certainty.
- Reduce dependence on foreign oil and the need to build expensive new power plants.
- Solar is environmentally safe, conserves resources and reduces air pollution which causes acid rain, the "Greenhouse Effect" and respiratory health problems.
- The ProgressivTube has no moving parts to fail or maintain.
- The unit doubles the hot water supply of the house when added to an existing water heater.
- The ProgressivTube unit comes with a 10 Year Factory Warranty including freeze damage and has a minimum design life of 30 years.
- Solar Energy is technology that contains the cost of the fuel in the initial price of the equipment.
- Can be used as a stand alone heater; great for remote areas or where no electric is available for heating water.
- Can be installed on almost any house as a retrofit, connecting to the existing water heater.
- Can be installed on the roof or the ground.
- The best time to install a solar water heater is when a home is being built. The homeowner is immediately in a positive cash flow position because the utility savings are far greater than the mortgage payment increment for the solar water heater.
