Maintenance tasks should be done by either an authorized dealer or by technical
experts from the Service Department of SUN&HEAT.
Maintenance consists of inspections (and possible repairs) and also replacement of
some parts for each component of the solar system as shown below:
Solar collector
- inspection of the collector front cover, i.e. the glass
(for breakage, dirt/dust, shading)
- inspection of the components fastening the collector
with the support structure (see Figure 4.7a and 4.7b)
- inspection of the water tightness of the collector
(sealing material of the glazing, the pipes, etc)
- inspection of the insulation.
Storage tank
- replacement of the combined “safety (pressure)
and one-way valve” in the inlet of the cold water
to the tank
- inspection of the inside of the tank and removal of
any mineral deposits from the domestic water
- inspection of the electric heater and the thermostat
- inspection of the anode
- inspection of the metal flange with the electric
heater, thermostat and the anode
- replacement of the sealing flange of the above metal
flange
- inspection for leaks at the connection points of pipes
which were dismantled
- replacement of washers (blue, red) in the tank at
the points of the inlet and outlet pipes.
Supports
- inspection of the mounting frame of the solar
system (components and fastening to the floor)
Closed loop
- inspection of the parts of the closed loop
(connecting pipes, expansion tank, insulation, etc)
- replacement of the fluid inside the closed loop, use
of new antifreeze and corrosion inhibitor
- replacement of the safety (pressure) valve of the
closed loop
