Solar Water Heater Maintenance Dubai | Solar Water Heater Dubai
Essentially, all you'll be doing is circulating solar-heated water through a continuous loop of plumbing that runs from the roof mounted panels down to a heat exchanger, through a pump, and back to the panels again. The heat exchanger is simply a tank-within-a-tank that transfers the approximately 140 degrees Fahrenheit warmth of the loop water to the considerably cooler supply reservoir surrounding it.
Fittings tapped into that reservoir allow it to be placed in line between the well or city water source that feeds your house and the cold water inlet pipe to your electric or gas hot water heater.
Installation isn't quite that easy, since the pump must be regulated to keep it from operating when sunlight is not available. Therefore, the system must include a differential controller that utilizes sensors at the collectors and in the storage reservoir to govern the pump's operation. More sophisticated controllers incorporate features that deactivate the pump at preset upper and lower temperature limits and provide for freeze protection by intermittently circulating the closed-loop water or opening a drain-down valve. (A minimal-investment system could use a nontoxic antifreeze as a transfer fluid to achieve the same goal.)
Of course, for any installation to work, your site must be suitable for a solar application. Whether you plan on having a roof- or a wall-mounted system, make sure that no obstructions — especially buildings or trees — will be in front of the collector panels. Remember that you'll be using hot water the whole year round, so in addition to sighting the morning-to-evening swing of the sun (the azimuth), check the solar altitude at the winter and summer solstices. And, while you're at it, make a quick check of your proposed plumbing path, looking specifically for obstacles such as ductwork, headers, wiring, or waterlines that could thwart your efforts to get the copper tubing from one point to another.

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.

A solar heater turns the sun light and heat from the sun into energy to heat up your pool. These heaters are very popular in different parts of the world, particularly areas with higher temperatures and a lot of sunshine.
How Do Solar Heaters Work?
If you already have a pump and filter set up for your pool, then all you need to set up solar heating is a kit with solar panels and a few other installation necessities. However, even if you are a pretty handy person, it is usually best to let a professional install your solar heating kit. Typically, the solar panels are mounted in an area that will get the most southwestern sunshine in a day, usually on a roof or a rack of some sort. Five to six hours of sun per day is ideal. If you do not have access to that type of sun exposure, you can still use solar heating by increasing the square footage of the solar heating panels for greater temperature rise in the water. Solar pool heaters work well in most parts of the United States and are incredibly low maintenance.
Solar heaters heat your pool by pulling the water from the pump to the black panels. The water travels through the panels, absorbing any heat picked up by the sun before flowing back through the pump and filter and into the pool.
Advantages of a Solar Heater
Heating your pool by using a solar water heater provides one advantage that no other heater does: no direct operational costs. You can enjoy a heated pool all year round without having to worry about huge increases in your energy bills. People tend to use their pool heaters during peak times, which also happens to be when energy costs are the highest, but this is not a worry if you are using a solar heater.
Solar pool heaters are also more eco-friendly than most other options, since you are using natural resources to heat your pool, as opposed to using gas (which can emit carbon dioxide and other harmful elements during heating) or electricity (which requires the burning of fossil fuels to harness). If nothing else, solar heating is far more convenient and can usually be set up with whatever existing pump and filter you have, so you don’t have to worry about having to buy or set up new equipment.
Disadvantages of a Solar Heater
While there are several advantages to choosing a solar heater, there are a few disadvantages as well. Solar heaters do cost less in the long run when it comes to their operational costs, but the initial installment can be expensive. Depending on the size of your pool, they can also take up a considerable amount of room, so it is important to consider whether you are okay with solar panels taking up room on your roof, lawn, or anywhere else you may need to set them up.
The other thing to consider when it comes to choosing a solar heater is the wait time; a common complaint is that solar heaters do not heat as well (or at least as quickly) as gas or electric heaters. Solar heaters can take longer to heat the pool water, since they use energy and heat pulled from the sun rather than a separate heating element. Also, since a solar pool heater does pull its power from the sun, it is subject to weather conditions. On windy or cloudy days, you will not get the same results as you would on a bright and sunny day. A pool cover will allow the heating system to retain heat during those cooler, overcast days.
There are several options when it comes to deciding how you would like to heat your pool. Solar heating tends to be popular for its environmentally friendly process, low-cost use, and convenience, but there are disadvantages. It is important and recommended that you research different options to see what will work best for you before making a choice. Always consult a professional before attempting to install or set up any heating system.
