2. Direct Frost Resistant System – Close Coupled System (Thermosyphon
Circulation Method)
The Direct system with solar vacuum tubes is used in areas where the ambient temperature
falls below 5ໍC and the water quality is good (less than 600ppm total dissolved solids/
minerals.
The water to be used from the solar water heater circulates through the manifold of the
solar vacuum tubes, transferring solar energy into the storage tank. The solar water heater
is fitted with a thermostat and element in the event the solar energy is not strong enough to
heat the water to the required set temperature i.e. on overcast days and in the evening.
A pipe set is supplied with silicone inserts to connect the solar water heater to the manifold
of the solar vacuum tubes manifold, in order to prevent freezing. The manifold is insulated
and resistant against freezing.

3. Indirect Frost Resistant System - Close Coupled and Split System
(Thermosyphon and Pumped Circulation Methods)
The Indirect system is used in areas where frost occurs, where the ambient temperature
fall below 5ໍC and the water quality is poor (more than 600ppm Total Dissolved Solids/
Minerals).
