What is Solar Water Heater?

Solar water heaters—sometimes called solar domestic hot water systems—can be a cost-effective way to generate hot water for your home. They can be used in any climate, and the fuel they use—sunshine—is free.

Why Solar Water is Mandatory in Karnataka?

Solar water heaters are mandatory in Karnataka for new buildings due to energy conservation goals and to reduce the strain on the electrical grid. The policy requires installation in new dwellings of a certain size to lower electricity bills, promote the use of renewable energy, and reduce the need for conventional energy sources like electricity and gas. This regulation is based on the Energy Conservation Act 2001 and is enforced through conditions for obtaining occupancy and electricity connections. 

What is Non-Pressurised?

A non-pressurized solar water heater is a simple, gravity-fed system that uses natural convection to heat water. These systems are cost-effective and suitable for situations where the overhead storage tank is positioned at least a few feet higher than the solar collector, as they cannot handle high water pressure. They work by using the heat from solar collectors (like vacuum tubes) to warm water, which then naturally rises into an insulated storage tank while cooler water sinks to be heated. 

What is Pressurised?

pressurised solar water heater is a system designed to handle high water pressure from a mains supply or pressure pump, delivering consistent hot water with high pressure to faucets and showers. These systems use a sealed, insulated tank to store heated water and can withstand high pressures, making them suitable for high-rise buildings and modern homes with high-pressure plumbing. They are often more efficient at heating water and maintaining temperature compared to non-pressurized
