Solar water heaters have gained popularity in recent years and are now being used by many individuals for residential purposes and by industries for commercial purposes due to its incredible advantages. Solar water heaters ensure that the environment is not harmed while also saving a lot of money on power costs. They require very little maintenance and are quite simple to install. Overall, a solar water heater installed once will last for many years and save you a lot of money. Different varieties of solar water heaters are produced by solar water heater manufacturing machinery in India, and you can choose the one that best meets your needs and price range.
How does solar water heaters work?
Depending on the model, solar water heaters either utilise the sun’s energy to directly heat water, which may then be used to meet domestic hot water needs, or they use the sun’s energy to warm another fluid, which is then used to heat the water. A storage tank is necessary for all systems, whether active or passive. Solar water heaters may function in cold climates, less sunny areas, and under a variety of other circumstances, albeit they will be less effective than in locations with more sunshine.
Cost of solar water heaters
The price will vary according to the solar heater’s type and capacity. In case of domestic use, it will also depend on the size of the family that will be served. Additionally, the price is determined by the size, manufacturer, and kind of solar water heating system, as well as the kind of roof that the panels are put on. Also, it depends upon the requirements of various national building codes and panel orientation. The size and kind of the installed system affect the price of the solar water heater. The smallest system capacity is 100 litres per day, which translates to 100 litres of hot water per day at a temperature of 60 C. A system with a 100 Ipd capacity is sufficient for a household of three to four people, and depending on the system’s kind, it may cost between Rs. 15,000 and Rs. 22,000 in India which can vary.
If an above tank is not built in a building or house, a cold water tank and its stand must be purchased separately from the system cost. If there are additional bathrooms, the cost of the hot water insulated pipe line could be higher as well. The cost of all these additional components might rise by 5% to 10%. However, when we choose a system with a bigger capacity, the cost decreases proportionally rather than rising linearly.
Ideal maintenance for Solar Water Heating
Domestic solar water heating systems don’t require a lot of maintenance. Plumbing leaks that occur sometimes might be quickly fixed by regular plumbers. Scale buildup in the collectors over time is possible if the water quality is hard. It is preferable to get in touch with the suppliers since this can require acid descaling. If outside surfaces are painted, it could be necessary to repaint them every two to three years to keep the surfaces protected from corroding. Once every five days, maintenance comprises cleaning the dust that has accumulated on the glass surface. Daily glass cleaning will help the system run more effectively. Making sure that the main cold water tank, from which water is fed to the solar tank, is always filled to the proper level is another crucial task. Utilising an automated level controller can aid in keeping the ideal water level.
