It is important for the reliable operation of the solar water heater to perform the
following tasks
• Insulate the hot and cold water pipes for higher efficiency and protection
against frost.
• Fix the pipes onto the floor surface as well as onto the walls, to avoid
problems appearing during operation of the solar water heater
• It is recommended that the insulation, covering the pipes, is either shielded
from the solar radiation by appropriate material or it must be painted with
special paint, so as to avoid degradation.
