SunEarth Solar Water Heater - Complete System

SunEarth Solar Water Heater - Complete System
                Active - Closed Loop

 Indirect (closed loop) solar glycol systems use propylene glycol as the heat transfer fluid in the solar array to overcome issues of freezing (glycol can tolerate – 60F in high concentrations) and eliminate scaling. The glycol is separated from the potable water by means of a heat exchanger that transfers the energy from the array into the storage tank.

Indirect solar water drainback systems are also a indirect design that use a heat exchanger to separate the collector loop from the potable water. Instead of relying on glycol for freeze protection, this system allows all the water in the array to drain back from the array and into a storage vessel in the solar loop when the pump is turned off. Because the array completely drains, water can be used in the solar loop, which avoids the need for double-wall heat exchangers demanded in some localities.

With nearly 1/3 of the average electric bill devoted to heating water, a solar hot water system is the smart choice and best investment you can make for your house and for the environment. Solar hot water systems supply an average 70-100% of a household annual water heating needs!

Product Warranty - 10 Year Manufacturer Warranty

Flat plate collectors employ the green house effect. The glass covering permits up to 90% of the visible sunlight to enter the collector. When the light passes through the glass its frequency is changed slightly to a lower energy level. When the light strikes the absorbing surface of the flat plate inside, the light is absorbed as heat. The combination of the glass frequency change and the solar absorbing surface of the plate capture the maximum amount of energy. As the absorber plate heats up it begins to radiate energy as infrared (IR) or heat radiation. Glass is essentially opaque to IR wavelengths so the heat is trapped increasing the temperature.

Solar Water Storage Tank Features:

Tank System Assembly:

When tank is purchased with a solar water heater kit, the system comes pre plumbed and wired as a complete assembly. This is called the Tank System Assembly or TSA. The TSA contains the water heater tank, pump controller, tank sensor, drain valve, system drain valve and the wiring and piping to make all connections. The TSA, the collectors and the interconnect piping make up the complete system.

• Pump: The system comes standard with a single TACO 006BC4 circulator pump. It uses 115V regular AC power which is supplied from the controller. When heat is available in the collector the pump is energized to circulate the water through the interconnect piping to the collectors where it gains heat. For additional options, click here

• Controller: The controller is powered by 115V house current and is the device that determines if solar energy is available. The controller, through the sensors, constantly measures the temperature of the water heater tank and the collector, comparing them to see if the collector is hotter then the tank.

• Sensors: The system contains 2 sensors, one at the outlet of the collector and one on the bottom of the water heater tank. The controller uses these 2 sensors to measure tank and collector temperatures. They are simple thermistor (thermal resistors) type sensors that have an inverse reaction to temperature. As the temperature goes, up the resistance goes down. The controller is calibrated to read this as temperature changes. As the collector heats up the resistance goes down and at the right point the controller turns on the pump. The reverse happens when the collector cools off.

• Water Heater Tank: This is a highly insulated glass lined steel tank that is constructed much like any other water heater, except that it also has additional inlet and outlet for the solar connections.

• Temperature and Pressure Relief Valve: This device is inserted into the water heater tank for safety. It is located on top of the tank. The T&P relief valve is preset to open and discharge if either a high pressure or high temperature situation occurs in the water heater. All water heaters regardless of whether they are solar power or not, must have this safety device which is required by national building codes.

• Isolation Valve: Also called "Shut Off Valve", this valve is installed in the cold water service line to the water heater. It is used to isolate the system for maintenance, repairs and service.

Solar Water Heater System Sizing & Performance

Performance varies depending on the type and size of the system, the amount of sun available at the site, proper installation, and the tilt angle and orientation of the collectors. We can perform a solar site analysis for you or show you how to do your own to ensure you select the best system to meet your needs.

Sizing Your Solar Water Heater System
Proper sizing and selection of your system will insure years of trouble-free hot water service to your home. A good rule of thumb for sizing your system consists of two parts; Collector size and Solar storage.

Collector size:
Collector size is calculated at about 20 ft² of collector area for each of the first two family members and 8 ft² for each additional family member.

Solar Storage:
Solar Storage, or tank size, is calculated at a ratio of at least 2 gallons of storage capacity to 1 ft² of collector area.

The models below are designed for tropical or southern climates where freeze seldom occurs. Recommended for region A on map.
