Solartherm S200ID Indirect 200L 400kpa Solar Geyser

Indirect systems are more complex in that apart from all the other components, there is a heat exchanger, either as a sleeve on the outside of the tank or a suitable, mostly copper or stainless steel apparatus inside the tank to transfer temperature from the panel to the water inside the geyser. Panel size / performance must be matched to the capacity of the storage tank in such a way that the system works efficiently.

In all the tests done at the SABS by various solar companies who elected to have their systems tested in conjunction with a Solartherm® geyser, test results show high to very high efficiency levels.

Product Description


Solartherm® Geysers produce 2 types of indirect geysers, the "Standard" type heat exchanger, and the "Trumpet" type heat exchanger. In both cases the heat exchangers can be replaced or repaired in the event of future failure.

The "Standard" type geyser was designed to accommodate passive (Thermosiphon) and active (Pumped) operation. The "Trumpet" type geyser was designed for active (Pumped) operation only. Both systems find their uses and acceptance in the market place and offer the customer various options. Indirect system heat exchangers are filled with a food grade glycol (anti-freeze) solution, which therefore prevents the panel from freezing up or blocking, and increases the boiling temperature of the transfer fluid. By being able to select a glycol mix as transfer fluid, the problem of lime and/or other build-up is also prevented.

The installation of active indirect systems, as well as their maintenance is more involved than passive indirect systems or active / passive direct systems. The glycol mixture should be replaced at least every three years.
