Hot water, day and night, 365 days.
Hot water is a basic necessity, which unfortunately can be expensive if availed through traditional water heating methods. Turn to the power of the sun for your residential or commercial water requirements and benefit from instant hot water all year long, at practically no cost.
Whether you run a home, office, hotel, hospital or an industrial establishment, quick and easy access to hot water is not just necessary, but rather, critical to your operations. Relying on boiler technology is not a cost-effective solution in the long-term, running up heavy electricity bills, month on month, year after year.
Every business and home can gain from the abundant power of the sun through a solar water heating system, which provides clean and renewable energy – thus balancing commercial and environmental impact.
This solar collector is made of an aluminium body and has a toughened glass sheet on the top. The heart of the collector is a copper absorber plate which is selectively coated for better performance. This plate absorbs the maximum possible heat from the sun and passes it to the water. The collector box is well-insulated to prevent any heat loss.
An evacuated tube acts as an absorber in this type of solar water heater. Each evacuated tube consists of two glass tubes with a vacuum in between, which acts as an excellent insulator. The incident solar radiation falling on the tube passes through the outer transparent tube and strikes the inner tube (having a dark absorbing coating). It absorbs the heat energy and then passes it to the cold water flowing in the tube.
How does the water stay warm?
In this the water in the storage tank circulates continuously through the collectors, based totally on the natural flow of water due to difference in specific gravity of hot and cold water. It does not have to rely on electricity and is a simple and maintenance free system. However in this system, the temperature cannot be controlled and as hot water is drained from the tank, it is replaced by fresh cold water, leading to some amount of mixing.
The flow in this system is controlled through a control panel and pump. The cold water is circulated through the collectors and allowed to stay there until the set temperature is reached. Only then does the pump come on and push the heated water into the storage tank. The entire system is automated and hence it has to rely on electricity supply. In this system the temperature can be controlled, and water in the storage tank at any given time is at the set temperature only.
Hot water during non-sunny days too!
The insulated storage tank can be fitted with an optional heating element
which will allow the system to function all-year-round.
