Standard AE Copper Absorber

WATER HEATING SYSTEM

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

These new packages include the solar hot water system components ONLY; collectors, racks & mountsand the hot water storage tanksmust be added on to make a complete system.

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.

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.

At the heart of these systems are the AE Collectors (SOLD SEPARATELY!) 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.

Every AET/Thermafin Absorber Plate is coated with durable and efficient Crystal Clear™ Selective Coating. The coating, which cannot be removed from the fin on an absorber plate, is based on single-phase nano-technology, pioneered by AET/Thermafin. Crystal Clear™ Selective Coating increases solar collector efficiency due to its unique optical properties. It has the ability to strongly absorb short-wave light (absorptivity: <0.96) while simultaneously reflecting long-wave light (emissivity >0.8). These intrinsic properties of Crystal Clear™ enable the collector to reach optimum temperature in a minimal amount of time and retain the absorbed heat longer.

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.

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.
