A water heater and a method of heating water utilizing microwave energy are disclosed. The water heater includes an inlet pipe connecting tubular coils. The tubular coils overlap over one another in a pyramid-shape structure. The tubular coils include a microwave generator positioned adjacent to them. The water heater includes an insulation member that positions around the tubular coils. The tubular coils connect to an outlet pipe including a pressure relief valve and a switch. The inlet pipe supplies cold water to the tubular coils. The microwave generator produces microwave energy directed at the tubular coils. The microwave energy penetrates into the tubular coils and heats up the water. The insulation member reflects back the microwave energy into the tubular coils and ensures there is no loss of energy. The hot water flows through the outlet pipe.
