Solar Water Heater

 Solar Water Heaters

As we know that Heating water is very expensive as it requires a huge amount of energy. It is accepted that 18% of domestic energy is utilized to warm water. In many homes and organizations, this energy is produced from petroleum products – gas and oil. Most current domestic boilers will run on gas and warmth water on interest. Be that as it may, numerous individuals actually heat their water utilizing the power which is the most expensive way to heat water.

A Solar water heater helps you reduce your electricity/LPG consumption for water heating. You can contribute to reducing your carbon footprint.

However better ways of reducing carbon footprint and lowering your energy consumption exist which utilize the sun’s energy with much higher efficiencies and hence better return on investment can be achieved viz., grid connect solar solutions.

It'll save you money. Solar hot water doesn't depend on fossil fuel to generate electricity rather it harvests energy from the sun to heat/boils your stored water for you.

Reduced energy use. That is if you already have a preinstalled solar/inverter system, solar hot water is a sophisticated system of its own that absorbs energy from the sun to heat water.

In an on-grid or grid connect solar, the energy converted from the sun is fed to the load and in absence of load, it is fed to the grid. You either get paid for this feed-in energy or the energy is adjusted against your nighttime consumption and you pay for the net.

Disadvantages and Advantages of a Solar Water Heater

Advantages of a solar water heater

1. Using the Solar Heat Energy:- The solar water heaters, help in tapping into the free heat energy offered by the Sun, thus saving a lot of electricity which will otherwise be used by electrical heaters, thus increasing electricity consumption. The solar heat energy of the solar water heaters can be used to heat water, thus providing hot or at least lukewarm water anytime between 11:00 AM and 5:00 PM.
2. Reducing Electricity Bills: Large amounts of electrical power is consumed by heating equipment. Although appliances such as ovens and room heaters are not used regularly, the water heaters are used regularly. Thus, electricity can be saved by the use of solar water heaters.

Disadvantages of using a water heater

1. Poor Efficiency:- Water heaters generally have very poor efficiency and are best to use only in places where they have hot tropical climates. E.g. Coastal areas of Southern India and Desert areas of West India.
2. Water wastage:- Normally, to get the hot water at the desired temperature, we need to run two to three buckets of water, which could result in wastage.

How Does Solar Water Heaters Work in Winter Season?

Everyone thinks and the first question comes into mind that in winter solar water heaters work? 

and the answer is............ Yes. 😄

With good insulation, sunlight will be able to heat the water quite well in a solar water heater even in winter. The heating is caused by the radiation energy of the sun, which can come through glass and heat up enclosures, even if the outside temperature is well below freezing - providing good insulation can ensure very small heat loss.

The solar water heater in winter functions admirably on account of productive protection that implies when the temperature stays cold during winters, radiator liquid innovation gets utilized in sun based water radiators.

Closed-loop systems pump a warmth exchange fluid, for example, liquid catalyst into the sunlight based gatherer. This fluid is warmed by the sun and after that pumped back to the capacity tank where a warmth exchanger exchanges the warmth vitality to consumable water.

SELECTING A SOLAR WATER HEATER

Before you purchase and install a solar water heating system, you want to do the following:

• Estimate the cost and energy efficiency of a solar water heating system
• Evaluate your site's solar resource
• Determine the correct system size
• Investigate local codes, covenants, and regulations.

Also understand the various components needed for solar water heating systems, including the following:

• Heat exchangers for solar water heating systems
• Heat-transfer fluids for solar water heating systems
