Abstract
This paper presents the design fabrication Parabolic-trough solar water heating is a well-proven technology that directly substitutes renewable energy for conventional energy in water heating. In Two meters parabolic solar concentration has been fabricated to produce boiled water up to 100oC for the purpose of central heating services. The concentration is toward the sun light during the day time; by using a control circuit, The amount of the portable water was much dependent on the accurate focusing of the system which increases according to preheating. This system could therefore be used for heating water at home via increasing the temperature in hot tank by covering the hot water and isolating the tank from the surroundings.
