This research was carried out to seek the possibility of minimizing of energy for heating water, by made a store with dimensions of 15x25x40cm, and connected it after the heater. Through used heater, the hot water divided to, consumption part and storage part. We could used hot water storage when, the water pressure was low, and the heater could not work. By used this storage, the energy for heating was minimized about 21% from the energy costs before used it. The total manufacturing costs of the storage was about 100 LE. We used a storage with heater in   ( El-soaly' poultry building) and minimizing of gas consumption.
