Standard water heaters, geysers, or immersion rods consume a lot of electricity as well as cost to produce hot water. They provide no means of energy saving or conservation. For economically privileged people they are a lot expensive and unaffordable. For places with no access to electricity, hot water can be a rarity.

Here, solar power comes to the rescue. Patra Global’s solar water heaters are becoming one of the most popular and widely used solar products in this country.

Active Solar Water Heaters

• Direct Circulation : These systems use a pump to circulate water from the solar thermal collector and into the household.
• Indirect Circulation : These systems use the pump to circulate a heat-transfer fluid from the solar thermal collector. This fluid then heats the water and transfers it through the house.

Passive Solar Water Heaters

• Integrated collector storage (ICS) : In these systems the storage stank and the solar thermal collector are attached to each other.
• Convection heat storage (CHS) : In these systems the storage tank and the solar thermal collector are separated and the transfer between them is made by convection.
• Patra Global has been successful in installing a 1000 litre solar water heater at Alipore in the South 24 Parganas district of West Bengal. The solar water heater is fully operational in providing hot water. The best part of the water heater is that it provides unlimited hot water without consuming any power.
