Dxb Solutions Solar heater has positioned itself to be the supplier of choice for those contractors and customers who demand the utmost reliability, performance and cost-effective solar heating systems. We offers a variety of solar water heating systems to meet your needs and requirements.
Please take the time to read this manual thoroughly before attempting to install the system. The Solar water heating system appropriate for your geographical and climatic area will provide you an efficient, reliable source of free hot water for years to come when installed according to this manual. Thank you for doing your part in energy conservation.
This manual describes the direct systems. This system uses potable water in the solar collector and it is open to the city pressures. This is designed for installation in areas where the air temperature falling below 41° F does not occur more than 3 to 4 times annually and this low temperature does not exceed an 8-hour duration.
Solar collectors are the heart of the system. Their main function is to absorb solar radiation and transfer the heat collected to the fluid circulating through the system. In the northern hemisphere the ideal orientation of Solar collectors are directly south and tilted to the degree of your local latitude. The collectors are mounted in an area (roof or ground) with a full solar window.
Solar collectors are made of all copper or copper aluminum absorber plate with high performance absorber coating, isocyanurate back and side insulation board, and safety tempered glass cover. All enclosed in a corrosion resistant galvanized steel frame. The collector absorber plate can easily be repaired or replaced if needed.
Solar water storage tank
The storage tank has a glass lining and an anode rod for maximum corrosion protection. Its internal manifold provides even distribution of heat and an injected foam insulation minimizes heat loss. The tank is available with or without an electrical element.
The controller is a differential temperature thermostat designed specifically to regulate a solar system operation. Its basic function is to monitor collector and storage temperatures and to automatically turn a small circulator ON or OFF at the appropriate temperature differentials. The controller can also provide additional functions, such as: system freeze protection (drain down / drain back or re-circulation), storage tank high temp. limit and positive OFF when the collector is below 80°F.
Low power circulation pump
All vital components are fabricated from corrosion-resistant, high-grade stainless steel. This quiet, self-lubricating circulator is maintenance free, and requires very little energy to operate. (UL Listed. 18-month warranty)
Using the basic system diagram a variety of system types and sizes and can be installed.
Sizing the System
Storage tank: Select 15 to 20 gallon per person per day or 15 to 20 gallons per bedroom (min. 60 gallon tank)
Example: For four persons household or for four bedrooms home select 80-gallon storage tank
Solar collectors: Select one half to one sq/ft of solar panels per one gallon of storage
Example: 80-gallon tank will required 40 to 80 sq/ft of solar panels.
All plumbing, electrical and structural must be installed according to specific local codes.
Solar Collectors Tilt and Orientation
The ideal orientation of Sun Ray Solar collectors are directly south (northern hemisphere) and tilted to the degree of your local latitude, but any direction within 90° from south is acceptable if the total degree of tilt + the orientation angle from due south is less then 130°.
Minimum system installation standards
Install the system according to the diagram.
Solar water heating systems require relatively little attention. But, as with any mechanical system, some basic maintenance is essential to keep the system functioning smoothly. The maintenance requirements of Sun Ray Solar water heating system are similar to those of conventional water heaters. The collectors, piping and storage tank should be checked for leaks, the system should be flushed periodically to remove tank and collected impurities (scaling in hard water areas). The systems should be checked at least twice per year for a proper operation of the pump, controller and sensors. The collector’s glass can be rinsed periodically to remove dust collected in order to improve collector efficiency.
