At present,the pain points for users of zero cold water gas water heaters are:① Using the preheating function significantly increases gas costs;②After preheating,the water temperature fluctuates greatly,which affects the bathing experience.In order to solve the above problems,this article explores the influencing factors of preheating water temperature,gas consumption,and preheating time based on the working principle of zero cold water and experimental data,and proposes a technical solution for energy-saving and temperature control of zero cold water gas water heaters.
