Abstract
A liquid heater may heat liquid using at least one of an electric heater or a hybrid heat pump. The liquid heater includes a tank to store liquid, an insulator at an outer surface of the tank, and a case surrounding the insulator. The case includes a first outer panel, a second outer panel, and a cover panel fastened between the first outer panel and the second outer panel. The cover panel is detachable from the liquid heater to access electronic devices such as a controller for the electric heater.
