Solartherm S200D Direct 200L 400kpa Solar Geyser

In a direct solar system, the water is heated by circulating water from the storage vessel through the solar panels. This can be done naturally via thermo-syphon or by a pump. The system is simple and cost effective however it must be noted that the pressure in the storage cylinder will be transferred to the panel which makes this unsuitable for some panels.

Should this system be selected in areas of consistently low temperatures (-0°C) in winter i.e. Sutherland and mountainous areas such as Drakensburg, Maluti and other cold areas, there are simple ways in controlled systems to stop panel freeze. In coastal regions and most other parts of South Africa, direct systems are highly suitable without the need for freeze control. Whether or not a panel freezes also depends to a large degree on the panel quality i.e. insulation, air gap etc. Furthermore, the integrity of the installation, the insulation of the pipes – particularly copper pipes etc. could be responsible for the system freezing.

Product Description


A direct system should not be installed in areas where the water contains high levels of dissolved solids. Depending on the severity of the problem the panel could get blocked up in a short period of time, rendering the whole system ineffective. In a direct system the geyser has no influence on the performance of the system, other than the temperature provided by the electric element as a back-up, since it functions purely as a hot water storage tank.
