• Easy to Install Tank Adapter and all Plumbing Hardware
Performance and certifications
System performance is affected by many changing variables including available solar energy, the solar collector(s) installed
pitch and orientation, the ground water temperature and ambient air temperatures, and the daily household hot water demand
comprised of bath, kitchen, and laundry uses. These conditions, which may vary from home to home even in the same
neighborhood, determine how much energy your solar system will save. This map shows an estimate of annual energy saved in
Kilowatt hours with the Hot2O System.
OVERALL SYSTEM
The following shall be the specifications for the solar water heating system. The system shall be a FAFCO polymer drainback type that isfreeze resistant, overheat protected, using unglazed collectors and polymer connection tubing.
COLLECTOR
The collectors shall be FAFCO unglazed UV resistant polymer collectors designed specifically for solar domestic water heating. The
dimensions of the collector shall be 144 inches in length, 24 inches in width with a ¼” or less absorber thickness. The weight of the
collectors shall be less than 1 lb/sqft when full of water. The collectors shall be fully chemical and corrosion resistant beyond the
capability of any metal. The collectors shall have excellent long-term weatherability as verified by 35 years or more of field installed
product, accelerated outdoor exposure, and other extensive laboratory testing. The maximum operating pressure shall be 30 psi
and maximum operating temperature shall be 200 degrees-F.
COLLECTOR MOUNTING HARDWARE AND ROOF JACKS
The mounted collector shall be anchored using FAFCO mounting hardware. The roof jacks shall be FAFCO low profile galvanized steel roof jacks with 5/8” I.D. water tight rubber grommets.
PLUMBING
Plumbing of the solar collectors to the drainback tank and circulation module shall be 1/2'” I.D. tubing rated for temperatures up to 200 degrees-F. Connections shall be of the push fit type with EPDM seal
that require no tools for securing. Mounting clips shall be used to secure the plumbing every 3 feet. All plumbing exposed to sunlight shall be either be made of UV protected material or covered with UV
protected material. A drain valve shall be installed above the circulation module to drain the drainback tank and solar loop.
SYSTEM PACKAGING BOX
Dimensions: 20-1/4” x 22-1/2” x 40-1/4”
ENGINEERING SPECIFICATIONS
DRAINBACK TANK
The drainback tank shall be made of a high temperature polymer capable of withstanding operating temperatures up to 200 degrees-F. The capacity shall be 10 gallons with dimensions of 33in. x 18in. x 5in.. The drainback tank will have an integrated sightglass for viewing the solar loop water level. The drainback tank will be vented to the atmosphere at all times by way of a vented cap.
CIRCULATION MODULE
The circulation module shall consist of a single unit with preassembled pumps, heat exchanger, filter, and wiring. The dimensions shall be 11in. x 11in. x 9in.. The voltage input shall be 120 volts. The heat exchanger shall be a copper brazed stainless steel plate heat exchanger. The potable loop shall consist of a low head pump with union connections and integrated 20 mesh filter connecting the heat exchanger to the solar tank. The solar loop shall consist of a high head pump with union connections connecting the drainback tank and solar collectors to the heat exchanger. The pumps shall be prewired inside the enclosure such that a single cord exits the enclosure through a protection grommet. The vented enclosure shall be made of a rigid polymer and shall be capable of easily opening to access or replace inner components.
SOLAR TANK CONNECTION
The solar tank connection shall be a coaxial tank adapter which allows the drainport of the solar tank to both feed and return the water in the solar tank tothe circulation module. The coaxial tank adapter shall be have a connection for the solar tank drain port, drain bibb, inlet connection to the circulation module, and outlet connection to the circulation module. Flexible hoses approved forconnecting domestic water heaters shall be used to connect the coaxial tank adapter to the circulation module.
SOLAR CONTROLLER
The solar controller shall activate and deactivate the circulation module based on temperature difference between the sensor installed at the bottom of thesolar tank and the sensor installed adjacent to the solar collector(s). The controller shall have digital accuracy and an animated LCD display that provides real time operating temperatures at the solar collectors, solar tankbottom, and optional solar tank top. The controller shall have varistor highvoltage spike protection and fused output protection for the pump circuit. The sensors shall be either RTD type 1000 or thermistor type. The controller shall have an adjustable high limit temperature of for the storage tank. There shall be an accessible side-mounted on, off, and auto switch on the controller housing.
STORAGE TANK
The solar storage tank shall be approved for domestic water heating use with a minimum pressure rating of 150 psi. The tank shall include a pressure/temperature relief valve specified for 210 degrees-F at 150 PSI.
