EagleSUN™
WATER HEATING SYSTEM

AET’s #1 water heating system
The Natural Solution for Hot Water

The EagleSun 80 gallon system is designed for families with 3-5 members. The EagleSun has fewer system components than any other active solar system, making the system more dependable and virtually maintenance free. The EagleSun will pay for itself several times through energy savings. Taking full advantage of the exclusive AET Black Majic selective coating and unique energy distribution technology, the EagleSun achieves new levels of performance and efficiency.

The EagleSun 120 is a packaged, fully integrated residential hot water system designed for the energy-minded homeowner who wants both savings and leading-edge technology that contributes to a cleaner environment. The EagleSun 120 is delivered complete with AET collectors, a 120 gallon solar tank, side-arm heat exchanger, and back-up heating element, making the system suitable for all climates.

System Features

• Fewer components for easy system installation.
• Works on sunny or cloudy days with included electrical backup (may not apply in off grid situations).
• Attractive collector design.
• Conforms to national plumbing, electrical, and solar standards.
• The only household appliance that will pay for itself several times during its useful life.
• Exceeds Energy Star criteria, delivers maximum credit toward Energy Efficient Compliance.
• The collectors come with a limited 10 year Warranty and tanks come with a limited 6 year Warranty.

At the heart of these systems are the AE Collectors with their solid copper absorber plates. Efficient solar energy absorbers begin with high thermal conductivity between the fin and tube.

Forge weld crossection x-ray

The AET welding process actually makes the tube one with the fin and creates a joint at least two times wider than the thickness of the copper fin, resulting in a clean. uninterrupted heat path unlike any other.

AET absorbers have no soldered or crimped seam joints to weaken or fail. The forge welding actually strengthens the joint area, unlike other welding processes, such as ultrasonics, which causes a weakening of the fin around the joint area.

AET uses the world's finest solar selective coating on their absorbers. The revolutionary Black Majic coating was developed by AET as a collaborative effort working with Coating Industry Professionals from broad based backgrounds. Black Majic is environmentally benign and boasts an emissivity of approximately 0.10 and absorptivity of approximately 0.95 !!!

This premium absorber is encased in a solid extruded aluminum frame and covered by a sheet of durable, low iron, tempered glass. The collector plate is insulated from the aluminum frame by a layer of foil faced poly-isocyanurate foam on the sides and back. The foam, in turn, is protected in the rear by a layer of embossed aluminum. Finally the entire unit is gasketed all the way around by a high temperature silicone sealant.

These Indirect, or Closed Loop PV systems include a 10 or 20 Watt Shell polycrystalline photovoltaic panel, depending on the size of the system. Unlike other systems, there is no Differential Temperature Controller (DTC) to control the pump. The solar panels are connected directly to a 12 or 24 Volt March DC circulation pump. These PV systems will continue to produce hot water in the event of temporary grid failure and can be used in off grid applications. The potable water in the insulated storage tank never touches nor mixes with the fluid in the collectors. The heated collector fluid is directed through the heat exchanger, which transfers heat from the collector loop fluid to the potable water in the solar tank. The 80 gallon tank has an internal heat exchanger while the 120 gallon model has an external or "side arm" heat exchanger. While the external heat exchanger functions well, the internal heat exchanger is inherently more efficient.

Sizing Your System

Sizing a solar water heater involves determining the total collector area and the storage volume required to provide 100% of your household's hot water during the summer.

Solar storage tanks are usually 50-, 60-, 80-, or 120-gallon capacity. A small (50 to 60 gallon) system is sufficient for 1 to 3 people, a medium (80-gallon) system is adequate for a 3- or 4-person household, and a large (120-gallon) system is appropriate for 4 to 6 people.

A rule of thumb for sizing collectors: allow about 20 square feet of collector area for each of the first two family members and 8 square feet for each additional family member if you live in the Sun Belt. Allow 12 to 14 additional square feet per person if you live in the northern United States.

A ratio of at least 1.5 gallons of storage capacity to 1 square foot of collector area prevents the system from overheating when the demand for hot water is low. In very warm, sunny climates, experts suggest that the ratio should be at least 2 gallons of storage to 1 square foot of collector area. For example, a family of four in a northern climate would need 20 square feet of collector area for the first person, 20 for the second person, 12 to 14 for the third person, and 12 to 14 for the fourth person. This equals 64 to 68 square feet, multiplied by 1.5 gallons of storage capacity, which equals 96 to 102 gallons of storage. Because you might not be able to find a 96-gallon tank, you may want to get a 120-gallon tank to be sure to meet your hot water needs.
