Advantage of Portable Solar Water Heater
On average, if you install a solar water heater, your water heating bills should drop 50%–80%. Also, because the sun is free, you're protected from future fuel shortages and price hikes.
While solar systems incur an initial investment, they end up being more economical in the long run. The reason being that they cut your reliance on the electrical grid, saving a large number of your electricity bills. These savings depend on a few factors like your heater's energy factor rating and your household's hot water usage.
Sunlight is a renewable energy source, meaning it does not pollute the environment and is available in an infinite amount. Electrical power stations mostly rely on fossil fuels like coal. Such fuels harm the environment by releasing toxic gases and are limited. This makes solar energy an eco-friendly option.
According to the Department of Energy, your hot water accounts for 14% to 18% of your utility bills. Homeowners spend hundreds of dollars on natural gas and electricity every year to heat the water in their homes. Although installing solar equipment comes at a high price, homeowners see savings of $781 on energy costs each year and a 100% return on their investment in just a few years. From then on, the sun produces free hot water.
Solar water heaters require little maintenance, just call in a professional every few years to replace the antifreeze in your solar hot water system and you should be fine. The only time you might need to maintain your system is when your home has a high level of hard water mineral deposits which can clog the system. But that can easily be remedied by installing a water softener.
Types of Solar Water Heaters
Drainback Solar Water Heating System
It uses distilled water as the heat transfer fluid. It acts as the medium and flows through the collector loop. The water flows through the collectors with the help of the pump. Drainback Solar Water Heating System is a non-pressurized system. The water flows to the heat exchanger and the storage tank under gravity.The system turns off when the pumps are off. It also has a setting which turns off the system when the water in the storage tank is too hot. Drainback Solar Water Heating System needs installation of the large piping system. However, it is more convenient as it does not need any check valves, pressure gauge, air vents etc.
Active Open Loop Solar Water Heating System
This is a simple and cheap system which works on the principle of heat transfer through water under standard pressure. The system has a temperature controller at the base of the storage tank.When the water in the storage tank is cold, the differential controller activates the circulating pump. This draws the water from the storage tank to the solar collector where it gets heated up and returns to the top of the tank. Active Open Loop Solar Water Heating System delivers high performance due to low heat loss.
Passive Solar Water Heating System
It needs an installation on the rooftop which also needs storage tank on the top. The system consists of the collector which takes up the cold water provided by the city supplier. In this collector, the water gets heated.The heated water flows to the storage tank where the water remains for the rest of the day until utilized. The chances of heat loss are more during this storage period. The thermosyphon system is a variation of this system which uses an insulated tank for storage of the heated water.
Active Closed Loop Solar Water Heating System
The water heating system makes the use of the heat-transfer fluid (HTF) that flows through the heat exchanger and collector. This HTF is non-toxic in nature and help to transfer the heat to the water stored in the tanks. In the majority of the systems, glycol is the HTF which needs replacement every 3-10 years. However, this system is a little complex as the collector remains constantly under pressure.
Evacuated-Tube Solar Collectors
The system has transparent glass tubes arranged parallel to each other. These tubes have an inner metal absorber tube with a fin. The surface of the fin has a coat which helps to absorb the solar energy. This is the commonly used system for the commercial purpose. The newer modification of this system has tempered glass cover plates. These plates help to enhance the durability of the heaters.
Application of Portable Solar Water Heater
Agriculture
Agriculture is an area that is often overlooked by people but perhaps offers the best opportunity for solar water heaters. In this agricultural industry, sanitization is heavily enforced and hot water sanitization is highly required sometimes as often as four times a day! However, this indicates that a lot of hot water is used in this industry. Note that it is not so uncommon for a dairy farmer to consume 2,000 to 4,000 gallons of hot water every day. Another major benefit that large agriculture facilities have is generally un-limited roof space with clear skylines throughout the day. Farms that are out in the open area with no neighboring buildings can easily go for solar water heaters for commercial purposes.
Hotels
Hotels are a great opportunity to install solar water heaters. Generally, hotels have a huge hot water demand starting with the showers in the washroom, they also have to wash the sheets on a daily basis, and this requires tremendous amounts of hot water every day. Besides, every hotel restaurant also requires an ample amount of hot water constantly for their dishwashing and food preparation. If a hotel has an indoor pool, then they have a major heating bill in the winter that can be largely supplemented by solar water heating systems.
Large Apartments And Multi-unit Dwellings
A majority of apartment owners nowadays have a shared hot water facility for all units out there. However, this can be more expensive especially when the landlord pays the water bill. So, when a central heating system is used, it becomes easy for a landowner to supply free solar water to the tenants by installing a commercial solar water heater.
5 Tips to Maintain Your Solar Water Heater
Ideally, solar-powered water heaters require maintenance every year. And, to ensure that your solar water heaters continue to function well for as long as possible, there are a few things that you need to ensure they are properly checked. Here are some of them:
- Check for leakages in pipes or tanks. Make sure there are no leakages, otherwise it may affect the performance of the solar water heater.
- Check for tears in the insulator. If there are any, then get them fixed as soon as possible.
- If there are any loose wires, get them fixed to prevent them from hanging.
- Check to ensure that all nuts and bolts are in their place. If they are loose, tighten them.
- The storage tank should have no leaks or cracks on it.
- The collectors should not be dusty at all.
You do not need to always call upon a plumber or a technician to clean up your solar heater; You can do it yourself. In fact, you should make it a habit of cleaning your solar heater regularly. Sometimes, dust can settle in your heaters, especially so when most solar water heaters are installed on rooftops, which is an area that is prone to dust. For such cases, all you need to do is to use spray your solar water heater with water, give it a good scrub with soapy water, and wash it off afterwards.
When it comes to the maintenance of a solar water heater, this is arguably the most important step. Flushing the system every year is important as it removes any dirt or dust that might have been accumulated over the year. A lot of dust and algae may get accumulated in the collector or tank, which can cause blockage and interfere with the daily operation of the solar heater.
Continuous flowing water can often cause corrosion in the water heater systems, leading to improper functioning of your heaters. The best way to prevent this is to clean the heater when not in use and keep it dry. This would avoid corrosion and erosion of the heater. Another method to overcome erosion is to paint the affected areas after cleaning them to prevent dysfunction of the heater.
Over time, hard water can result in the accumulation of mineral deposits in the solar heating systems. In other words, hard water result in the scaling of minerals. This interferes with the functions of the heater, thus reduces the capabilities of the heater to work efficiently. If the water in your houses is hard, chances are that scaling can occur at a more frequent rate in the collector, pipes and heat exchanger. This can cause the failure of the pumps and valves to heat water.
As descaling is a complex job, the best way to tackle this problem is to contact your plumber and get him or her to descale your solar water heater during your periodic maintenance.
Component of Portable Solar Water Heater
How we started
Solar Collector
The solar collector is the component of a solar hot water system that captures the energy from the sun and converts it into heat. There are two main types of solar collectors: flat plate collectors and evacuated tube collectors. Flat plate collectors consist of a flat, insulated box with a glazed surface and a black absorber plate. The glazed surface allows sunlight to pass through, while the absorber plate absorbs the sunlight and converts it into heat. Evacuated tube collectors consist of a series of tubes with a vacuum inside, which reduces heat loss and increases the efficiency of the collector.
Storage Tank
The storage tank in a solar hot water system is a container that holds the hot water and is typically made of stainless steel or other corrosion-resistant materials. The size of the storage tank depends on the hot water requirements of the home or building, with larger homes and buildings typically requiring larger storage tanks. The storage tank is connected to the solar collector and the hot water pipes in the home or building by a series of pipes and valves.
Heat Exchanger
The heat exchanger in a solar hot water system is a device that transfers heat from the solar collector to the water in the storage tank. It typically consists of a series of pipes or tubes that run between the solar collector and the storage tank. As the water in the solar collector is heated, it flows through the heat exchanger and transfers its heat to the water in the storage tank, which is then used for hot water.
Solar Water Heater Buying Guide
System Orientation and Tilt
The angle and orientation of the solar collectors play a role in their efficiency. Your location's latitude and the desired tilt angle should be considered. Go for an adjustable mounting structure.
Type of Solar Collector
Flat-Plate Collectors: These are the most common type. They consist of dark-colored, heat-absorbing plates within an insulated box covered by glass. They work well in moderate climates.
Evacuated Tube Collectors: These collectors are more efficient in colder climates and can even work on overcast days. They are made up of rows of glass tubes containing metal absorber tubes.
Climate
The amount of sunlight your region receives is a crucial factor. If you live in an area with abundant sunlight, a solar water heater can be highly effective. Remember: Active solar water heating systems give optimized performance, even in less sunny conditions while Passive systems are highly efficient in sunny conditions, but struggle during cloudy days.
System Size
The size of the system depends on the number of people in your household and your hot water usage. A larger system will be needed for a bigger family.
Backup System
Solar water heaters may need a backup system (like a conventional water heater) for cloudy days or increased hot water demand.
