Figure Number: Solar Series Single Coil Models
Solar System Single Coil Electric Backup Models
All electric water heaters are certified at 300 PSI test pressure (2068 kPa) and 150 PSI working pressure (1034 kPa). All potable water and electrical connections are 3⁄4" NPT (19mm) on 8" (203mm) centers. All models UL listed.
Single wall or double wall 1½” O.D. glass coated (Ultonium®) steel coil ensures separation of potable water and heating fluid. The coil has a heat transfer area of 14.2 sq. ft. and a stored water volume of 2.5 gal. Maximum supply temperature from the solar collector must not exceed 250°F.
Sensor Wires for Solar Thermistor Connections
Twisted wires are provided under the Upper and Lower covers. These wires have been provided as a means for connecting thermistors to a solar controller (Thermistors and Solar Controller are not provided).
Honeywell Manual Temperature Control
The Honeywell mixing device is manually set and is easily installed. It ensures a comfortable outlet temperature while providing a steady flow of hot water.
A dual, or single backup heating element (4500W standard, 5500W optional) provides heat only when solar energy does not satisfy demand. Dual element models allow entire tank to hold hot water during periods where solar heating is not available.
Factory Installed Sparge Tube System
Cold water inlet sediment reducing device helps prevent sediment build up in tank. Increases first hour delivery of hot water while minimizing temperature build up in tank.
Niles Steel Tank tanks are lined with a exclusively engineered enamel formula that provides superior protection from the highly corrosive effects of hot water. This formula (Ultonium®) is fused to the steel surface by firing at at temperature of over 1500°F.
Fully Automatic Controls
Fast acting surface-mount thermostat(s) for automatic temperature control. Factory installed sensitive manual reset energy cutoff for safety to prevent overheating.
Supply and Return Connections
¾” NPT female connections are located on the front for both the solar collector supply and return.
2″ Non-CFC Foam Insulation
Covers the sides and top of tank, reducing the amount of heat loss. This results in less energy consumption, improved operation efficiencies and jacket rigidity.
Potable Water Connections
¾” NPT factory installed true dielectric fittings extend water heater life and eases installation.
Two Protective Aluminum Anode Rods
Provide added protection against corrosion for long trouble-free service.
Direct Heat Transfer With Immersed Incoloy Element(s)
Transfers heat directly and efficiently to the water. Screw-in style.
Heavy gauge steel automatically formed, rolled and welded to assure a continuous seam for glass lining.
T&P Relief Valve
Brass Drain Valve
