The solar water heater must be integrated into future residential buildings as the main energy source, which will subsequently reduce cost of heating. An original configuration for efficient Domestic Hot Water "DHW" storage tank is developed and experimentally evaluated under Saharan climate. This novel DHW includes a hybrid (solar electric) system with flat plate collector coupled an electric heater. Additionally, phase change material "PCM" mixture that composed paraffin wax animal fat melting temperature between 35.58°C 62.58°C latent heat 180 210 kJ/kg this configuration. experimental results indicated hot production by using could economically attractive. In proposed configuration, one liter may around 0.1362 DZD/liter (i.e., 0.00096 US$/liter) compared to 0.4431 conventional heater, average savings 69.26%. On yearly basis, reach up 80.25% if optimal tilt adopted on monthly basis. vulnerable convective transfer, therefore, other collectors such vacuum tube provide enhanced performance.
