1, energy efficiency grade difference: EZ003 is the first-class energy efficiency, which is more efficient when using gas, saving energy and reducing the impact on the environment. EZ004 was rated as the second-class energy efficiency, slightly lower than the first-class energy efficiency, but it still has high energy-saving and environmental protection characteristics.
