When designing outdoor hot water pipes for solar water heaters, it is advisable to keep the pipes as short as possible to save on installation materials. This also minimizes the amount of stored water in the pipes, enhancing water resource utilization. Due to the shorter outdoor pipes, the likelihood of freezing and blocking in winter is lower. If electric heat tracing for automatic frost protection is installed, the amount of electric heat tracing required is reduced due to the shorter outdoor pipes. The specific installation location of the solar water heater should follow the following principles:

The solar water heater to be installed must be placed in a location that is easy to secure. Based on the current structure of the building, this is typically a flat or sloping roof. The primary factor in selecting a secure location on the rooftop is to position it near the chimney, exhaust vents, or pre-existing pipe wells.

The installation location of solar water heaters must be within the lightning protection zone of the building. Special consideration must be given to areas with frequent thunderstorms. If the building does not have lightning rod facilities, additional lightning protection measures should be installed.

Solar water heaters must be positioned in a location with ample sunlight and long hours of daylight, yet cannot obstruct the采光 for adjacent solar water heaters.

4. Any other requirements not mentioned should be implemented in accordance with the installation manual of solar water heaters and the requirements of local property management and users. The principle is to ensure the safe placement and normal operation of the solar water heater without violating relevant regulations.
