Construction of hot water systems typically includes the following steps:

1. Design Scheme: Tailor a suitable hot water system design based on the type, usage, and requirements of the building.

2. Material Selection: Choose appropriate pipes, valves, pumps, and other equipment and materials based on the design plan.

3. Construction Preparation: Prior to commencement, the construction area must be cleared, measured, and marked.

4. Pipeline System Installation: According to the design plan, install the pipeline system, including water supply pipelines, hot water supply pipelines, and hot water recovery pipelines, etc.

5. Installation Equipment: Install and wire pumps, water heaters, and other equipment.

6. Testing and Debugging: After completion of construction, conduct system testing and debugging to ensure the system operates normally.
