A solar water pumping system uses solar energy to pump water from a source, such as a well or a pond, to a designated location. This system is especially beneficial in remote areas where grid electricity is unavailable or unreliable. Solar water pumps are widely used in agricultural fields for irrigation, livestock watering, and domestic water supply.

Tank less water heaters heat water directly without the use of a storage tank. When a hot water tap is turned on, cold water travels through a pipe into the unit. Either a gas burner or an electric element heats the water.

Air conditioning is the process of removing heat and moisture from the interior of an occupied space to improve the comfort of occupants. Air conditioning can be used in both domestic and commercial environments. This process is most commonly used to achieve a more comfortable interior environment, typically for humans. However, air conditioning is also used to cool or dehumidify rooms filled with heat-producing electronic devices, such as computer servers, power amplifiers, and even to display and store delicate products, such as artwork.
