Advantage of Split Pressurized Solar Water Heater
Installing a solar panel is a lot cheaper in comparison to installing a PV panel. You can also earn rewards by transferring the unused unit back to the electricity grid. It's a one-time investment with long-term benefits.
Solar water heaters are low-maintenance devices. They only demand simple cleaning. They don't have moving parts and thus they don't suffer from tears and breaks which could need regular repairing attention.
Saves Environment and Space
Solar water heaters use solar panels and thus they are green devices. They aren't dependent on fuel. Additionally, they have low carbon footprints and zero-emission. They also save a lot of space. If you don't have enough room, you can go for a thermal panel.
Zero Cost
A solar panel is powered by the sun's energy and thus you don't have to pay any money to the power grid for using electricity. It is also a renewable source of energy. It's also available each day and completely free. You just need to figure out how to fine-tune your panel to optimize its performance on cloudy days.
Efficient
Solar water heaters are really efficient as solar panels have the ability to convert almost up to 80% radiation into heat energy. The panels can do so without even making use of any external fuels.
Different Between of Low Pressure Solar Water Heaters and High Pressure Solar Water Heaters
Low Pressure Solar Water Heaters
Typically characterized by vacuum glass tubes connected directly into a tank with a small holding tank on top of it. The low-pressure gravity system consists of a vacuum glass tube collector, an insulated storage tank and optional stand parts (make up tank). The evacuated glass tubes are filled with water and exposed to sun, thus heating up the water in the glass tubes.
Advantages
- This type of solar heater is simple, with no moving parts.
- Due to its simplicity, it is usually a cheaper option (roughly 50 - 60% of high-pressure systems)
- Due to lower pressure and stress on the tank and collectors, it has a longer life than mains pressure solar geyser systems.
- This type of solar heating system is lightweight.
- Can provide hot water without external power.
- This type of solar geyser system is highly effective in converting sunlight into heat
Disadvantages
- It has limited uses with modern plumbing systems, as it can only be used where there is small head of pressure.
- Unless it is installed at a high level above the water outlets the water pressure will be very low.
- It can cause serious scalding if not installed or used correctly.
- The entire solar heater system needs to be shut down even if one glass tube breaks.
- All the weight of the heater is carried by the roof which may need additional support.
- The tank does not look very attractive when installed on top of a roof.
- It breaks easily.
High Pressure Solar Water Heaters
Typically characterized by an enclosed heating unit containing copper tubes connected indirectly to a tank. The tank may be located next to heating unit or separately such as under the roof. The high-pressure Direct Pressure Solar Water Heating System features evacuated tubes and heat pipes. The evacuated tube absorbs solar energy and converts it into heat energy, this energy is then used in the process of heating water. There is no direct connection between the heating fluids in the copper tubes and the water being heated.
Advantages
- The main advantage is that the water pressure can be very high.
- Works well with water pumps that have been installed
- There does not have to be an 'unsightly' solar heater water tank on the roof.
- They can sometimes be retrofitted to use existing storage tanks.
- The tank or collectors can be located in more accessible or appropriate locations.
- More robust than low pressure systems.

Type of Solar Water Heater
These are the most common type of solar collectors for residential solar water heating systems.
Flat-plate collectors consist of a flat, insulated box with a dark absorber plate, covered with glass or plastic to allow sunlight to enter while minimizing heat loss.
They are typically used in both active and passive solar water heating systems.
Evacuated tube collectors are more efficient than flat-plate collectors, especially in cold or cloudy conditions.
They consist of rows of transparent glass tubes, each containing an absorber tube that is evacuated to reduce heat loss.
These collectors can be used in both direct and indirect circulation systems.
ICS systems, also known as batch or breadbox systems, integrate the solar collector and the storage tank into a single unit.
The collector is often a dark tank or tube exposed to sunlight, and the water is preheated before entering the conventional backup water heater.
ICS systems are simple and cost-effective but may be less efficient than other types in very cold or cloudy conditions.
Thermosiphon systems rely on natural convection to circulate water between the collector and the storage tank.
The collector is installed below the storage tank so that heated water rises to the tank, creating a natural flow.
These systems are typically passive and do not require pumps, making them more reliable but less suitable for installations where the tank is located below the collector.
Active solar water heating systems use pumps to circulate water or heat transfer fluid between the collector and the storage tank.
They are more flexible and can be used in a wider range of configurations, including both direct and indirect circulation systems.
Component of Split Pressurized Solar Water Heater
Solar Collectors
These are devices that absorb sunlight and convert it into heat. The two main types are flat-plate collectors and evacuated tube collectors. The collector is responsible for capturing and concentrating solar energy to raise the temperature of a heat transfer fluid or directly heat the water.
Heat Transfer Fluid (HTF)
In some systems, a heat transfer fluid circulates through the solar collectors to absorb and transfer heat. Common fluids include water, water-glycol mixtures, or other specialized fluids. The HTF carries the heat to the heat exchanger or storage tank.
Heat Exchanger
In indirect circulation systems, a heat exchanger transfers the heat from the heat transfer fluid to the water in the storage tank. This ensures that the potable water remains separate from the fluid circulating through the collector.
Storage Tank
The storage tank stores the heated water for later use. It can be a dedicated tank for solar-heated water or an integrated tank in the solar collector system. The size of the tank depends on the hot water demand and climate conditions.
Backup Heater
In regions with insufficient sunlight or during periods of high demand, a backup heating element may be included in the system. This backup heater, often powered by electricity or gas, ensures a continuous supply of hot water.
Pump (for Active Systems)
Active solar water heating systems use a pump to circulate the heat transfer fluid between the solar collectors and the heat exchanger or storage tank. This ensures a more controlled and efficient transfer of heat.
Controller
The controller monitors and regulates the operation of the system. It may control the pump, backup heater, and other components to optimize performance and prevent overheating or freezing.
Insulation
Proper insulation is crucial for minimizing heat loss from the storage tank and pipes, especially during periods of low sunlight or at night. Insulation helps maintain the water temperature and improves overall system efficiency.
Temperature and Pressure Relief Valve
This safety feature prevents excessive pressure or temperature buildup in the system. It releases excess pressure or hot water to prevent damage to the components.
Expansion Tank
In closed-loop systems, an expansion tank accommodates the expansion and contraction of the heat transfer fluid as it heats and cools. This helps maintain proper pressure levels in the system.
Application of Split Pressurized Solar Water Heater
Hotels
As part of a service-centric industry, customer satisfaction stands at the core of all hotels. Their overall electricity consumption is very high and the use of standard electric water heaters can further take this cost much steeper. As a result, the hotels are left with heftier bills, higher operating costs, and lower profitability.
Thus, solar water heaters prove to be a more economical choice for the hotel industry.
Housing Societies
Housing societies need large volumes of water every single day for maintenance and everyday requirements of the housing members. Installation of a solar water heater can help to reduce the overall electricity bills drastically.
Besides that, solar water heaters are highly recommended for eco-friendly housing societies that are moving towards a sustainable lifestyle. They can help the members reduce their carbon footprint while saving money.
Hospitals
Hospitals use large volumes of hot water daily for various purposes like cleaning, washing, and disinfecting the hospital premises. Thus, they need an efficient water heater that can supply hot water without any delay.
For institutions like schools and hospitals, solar water heaters are widely popular. This is because they are cost-efficient, easy to install, and need less maintenance. Additionally, using the best solar water heaters can also help the business generate up to 80 percent of savings.
Restaurants
Every day, restaurants consume gallons of hot water for dishwashers, restrooms, and the kitchen. Thus, they need an effective solar water heater to ensure an uninterrupted supply of hot water.
Solar water heaters not only help restaurants reduce their electricity bills but also help them adopt a sustainable approach to business. A consistent supply of hot water through a solar heater can significantly reduce their carbon footprint.
Manufacturing Units
In manufacturing units and plants, hot water is heavily utilised for various purposes. For instance, in the apparel industry, large volumes of hot water is needed for washing and dyeing. On the other hand, the chemical industry requires hot water for a plethora of treatments and production processes.
To ensure a steady supply of hot water in manufacturing plants, we suggest using a solar water heater.
