Abstract	Water heating is the fourth largest energy user in the commercial buildings sector, after heating, air conditioning, and lighting. It is a major energy user in building types such as restaurants, motels and hotels, hospitals, and other facilities that do a great deal of laundry or dishwashing. The energy requirements and consumption of the world including India are increasing at alarming rate and the power demand has been running ahead of supply. Fossil fuels when bum, create harmful greenhouse gas emissions and our planet is already feeling the impact of climate change. With the energy crisis worsening and conventional heating fuels becoming scarce and expensive, a need exists for the development of alternative heating fuels and systems. Solar energy which is "free" and readily available is a promising source of building heat. The solar energy can however be used to augment conventional heating systems or used to improve the performance of the system as with a heat pump. Detailed review of the literature on performance of direct expansion solar assisted heat pump water heater, in both summer & winter seasons was done. The performance of direct expansion solar assisted heat pump water heater experimentally investigated for producing the hot water under the winter climatic conditions of Kurukshetra (North India). The setup consists of single glazed flat plate collector as an evaporator with a surface area of 2.23m , an electrical reciprocating compressor of rated capacity 245W, an insulated hot water tank having a volume of 30 liters and capillary expansion tube. R-134a is used as a working fluid in the refrigerant circuit.
