[0002] Commercial water heaters are large-capacity, high-efficiency hot water supply devices designed for commercial venues such as hotels, schools, and factories. They are mainly divided into three categories: storage-type electric heaters, instantaneous electric heaters, and energy-saving air source heat pumps. Among them, commercial solar water heaters are commercial hot water supply systems that utilize solar energy as the primary energy source. Through a dual heat source design, they achieve all-weather water supply. Compared to residential environments, commercial water heaters have more complex and diverse piping paths, and some pipes are exposed, making them prone to freezing and cracking damage in cold weather.

The insulation sleeve 11 is placed on the outside of the inlet and outlet water pipes 10. By snapping the locking assembly onto the outside of the insulation sleeve 11, the insulation sleeve 11 is fixed.

[0027] Please see Figures 1-4 In this embodiment, the heating assembly includes a temperature sensor and an electric heating tube. The heating assembly is fixedly connected to the inner side of the water tank 2, and a control box is connected to the outside of the heating assembly. The insulation chamber 3 is fixedly connected to the outer side of the water tank 2. The insulation plate 4 has an arc-shaped structure design.

[0028] Please see Figures 2-5 In this embodiment, the insulation sleeve 11 is symmetrically arranged front and back and fits tightly against the outer side of the inlet and outlet water pipes 10.
