Envirosun TS Plus Solar hot water system TS300/40, TS300/50, TS300/60 close coupled solar hot water system/open circuit (Thermosyphon / Thermosiphon)
In the Envirosun TS Plus, open circuit, solar hot water system, hot water naturally rises and moves to a hot water storage tank. As the hot water comes in to the storage tank it pushes cooler water to the bottom of the tank (as the hot water rises the cold water falls) where the only option is to move via the lowest point of the solar storage tank then into the solar collector panels to be heated, as this cycle repeats continuously, the water in the hot water storage tank will get hotter and hotter until it reaches the system’s designed maximum temperature.
All of the Envirosun TS Plus thermosiphon open circuit solar hot water systems are protected by a safety solar arrestor valve, this prevents the water from overheating and causing the PTR (pressure/temperature relief) valve from discharging excessive amount of boiling water Envirosun use AVG TA-20, from the Australian Valve Group
Envirosun THX Plus Solar hot water system TS300/C/40 and TS300/C/60 close coupled solar hot water system/closed circuit (thermosyphon / Thermosiphon)
In the Envirosun THX Plus, closed circuit solar hot water system a transfer fluid “Glycol” is used. A closed circuit system to explain simply is like how your car uses water and a radiator to cool the engine, a closed circuit solar is like that in reverse the fluid flows through the solar collector panels, heats up from the sun, has a natural rising effect and transfers this heat to water in the storage tank through a outer jacket (also known as a heat exchanger).
