Solar Water Heater – Buy solar hot water heater for home at best price
A solar water heater is a solar device that heats water using solar energy. It use the sunlight to heat the water during the day. This hot water is stored inside an insulated solar hot water tank for use whenever required. It is among the most cost-effective uses of solar energy.
The solar energy from the sun is utilised for heating water very easily to a temperature of 55-70° C. And hence, if you replace your conventional water heater with a solar water heater, you can save up to 70-80% on electricity. Besides, it operates at low costs and is eco-friendly. This is the reason why thousands of people are installing solar water heaters every year.

With no maintenance requirement, solar heaters provide a low cost long term solution to getting hot water. For cloudy days, solar water heaters have an inbuilt electric heating element for backup. Basically, solar water heaters do conversion of sunlight into renewable energy for water heating using a solar thermal collector.
There are two different types of solar water heater available in various capacities. So it’s worth spending 10 minutes reading this information and selecting the best type and capacity of water heater that meet all your needs.
How does a solar water heater work?
In the daytime, the sun rays fall on the collectors. The absorbers present inside the collectors consume the solar radiation. As a result heat energy is produced. The solar collectors transmit this energy to the water streaming through them. This hot water is stored inside an insulated solar hot water tank for use whenever required. As the tank is insulated, it prevents heat loss. The flow of water from solar collectors to the tank continues due to the thermosiphon principle.
#1. Types of Solar Water Heater
To provide outcomes in different climates and latitudes and to satisfy your budget, a variety of solar water heater configurations are available in the market. The different types allow you to choose the one that matches your preferred efficiency, capacity, functionality and price. Although choosing the right one is slightly complicated, we are here to help you find out the heater that can serve you with the utmost benefits. Solar water heater comes in two major technologies:
FPC type solar water heater performs better in hot climatic conditions, while ETC type solar water heater performs better in cool climatic conditions. Both the types differ by the type of collector used to absorb the solar radiation. These are discussed below in detail.
#2. ETC Solar Water Heater
In ETC Solar Water Heater, the collector is designed to provide insulation using double layer borosilicate glass tubes. Each evacuated tube consists of two glass tubes having vacuum in between which is an excellent insulator. The outer wall of the inner tube is made to absorb maximum solar radiation. And that is why the wall is coated with demanding absorbing material.
Evacuated Tube Collector (ETC) acts as an absorber in the solar water heater. The incident solar radiation falling on the tube passes through the outer transparent tube and strikes the outer of inner tube. It absorbs heat energy and then passes to the cold water flowing in the tube. Hence, the heat gets transferred to the cold water resulting in heating the water.
An evacuated tube technology based solar water heating system is most energy efficient and cost effective that are best suitable for home use.
ETC Water Heater Price List
Generally, ETC solar water heater prices start from Rs.15,000 to Rs.55,000 depending on the capacity of the heater and its brand. ETC Solar heater range starts from Rs. 15000 for a 100L capacity heater. You can estimate the prices of all the different capacity ETC water heaters by looking at the table below.

#3. FPC Solar Water Heater
In an FPC solar water heater, the solar radiation is absorbed by Flat Plate Collectors (FPC) which consist of an insulated outer metallic box covered on the top with a glass sheet. Inside there are blackened metallic absorber (selectively coated) sheets with built in channels or riser tubes to carry water. The absorber absorbs the solar radiation and transfers the heat to the flowing water.
A flat plate technology based solar water heater is more energy efficient. Also it has a long life. Hence, such a heater is most suitable for home use.
FPC Water Heater Price List
The price range of FPC water heaters starts from Rs 25,000 for 100L capacity heater to around 1 lakh for 500L capacity heater. The price list is as shown below.

#5. Pressurized V/s Heat-Exchanger
Apart from types based on capacity, a solar water heater has certain other types based upon its functionality. These types are listed below.
Heat-Exchanger Water Heater
A heat-exchanger solar water heater uses heat exchangers to warm water. Here, water is heated through another heated medium which can be air or liquid. After the solar collectors absorb the solar energy, the heat exchangers transmit it to liquid or air. This heated liquid or air runs inside the water tank containing cold water through pipes. As the medium flows inside the cold water, the heat begins to exchange from the medium to water resulting in heating the water.
| Model | Capacity | Selling Price |
| HE 200L 2C SWH | 200 Liter | Rs.60,029 |
| HE 300L 3C SWH | 300 Liter | Rs.81,041 |
| HE 500L 4C SWH | 500 Liter | Rs.1,08,614 |
| HE 500L 5C SWH | 500 Liter | Rs.1,18,844 |
Pressurized Solar Water Heater
A pressurized solar water heater uses pressure to heat water. It is also known as the High-pressure Direct Pressure Solar Water Heater. While operating such a heater, the water in the tank should be kept under high pressure. The pressure of the tank water should resemble the pressure of tap water.
| Model | Capacity | Selling Price |
| Px 200L 2AL SWH | 200 Liter | Rs.63,622 |
| Px 300L 3AL SWH | 300 Liter | Rs.86,907 |
| Px 500L 4AL SWH | 500 Liter | Rs.1,27,677 |
| Px 500L 5AL SWH | 500 Liter | Rs.1,35,097 |
Pressurized with Heat-Exchanger Heater
A pressurized with heat-exchanger heater comes with the combined feature of both- a pressurized heater and a heat-exchanger heater. Similar to the heat-exchanger heater, it works with copper tubes connected to the tank. The solar energy heats the medium inside the copper tube which in turns transfers the energy to the cold water making it hot to a temperature of around 60°C. And like a pressurized heater, all this heating process is done under pressure.
| Model | Capacity | Price Rs. |
| Px-HE 200L 2AL SWH | 200 Liter | Rs.69,700 |
| Px-HE 300L 3AL SWH | 300 Liter | Rs.95,063 |
| Px-HE 500L 4AL SWH | 500 Liter | Rs.1,39,293 |
| Px-HE 500L 5AL SWH | 500 Liter | Rs.1,46,713 |
#6. Subsidy On Solar Water Heater
There are different policies for subsidy on solar in every state. Therefore, the subsidy rates on solar water heater vary. The genuine rates are:
- Rs.4,000 and above per 100 Liter and Rs. 8,000 and above per 200 Litre on FPC
- Rs.1,500 per 100 Liters and Rs. 3,000 per 200 Litres on ETC
