How does the Envirosun TS Plus solar hot water system work
The solar hot water storage tank and panels are connected together and located on the roof structure, facing in a northerly direction. Hot water has a natural fall and rise cycle, hot water rises and cold water falls to the lowest point, as the sun heats the water in the collector, it rises and then goes into a storage tank.
Hot water rises naturally in the tank – this process is called thermo-siphoning, that’s why this type of solar water heaters are known as thermosyphon solar hot water systems and the Envirosun TS Plus model
The colder water at the bottom of the storage tank then travels into the lowest point of the solar collector panel and as it starts to heat up it rises in the solar panels to the highest point, then through a pipe to the storage tank. (shown in diagram)
The solar hot water panels are a sealed cased box with toughened glass face, a manifold of copper pipes and black powder coated copper absorption plates or fins to attract the heat and with the underside being fully insulated, traps the heat inside to give maximum solar gain and heat transfer to the water
This process is a continuous cycle and can save the average household over 80% of their hot water energy usage and related greenhouse gas emissions, not to mention the money that is saved with this type of solar hot water systems
How does the Envirosun AS split solar hot water system work
The AS “active solar” Envirosun Solar Hot Water Heaters are also known as the split solar hot water system, they offer greater flexibility, improved aesthetics for your home and a larger hot water storage tank capacity
These solar hot water systems only require the solar panels to be installed on the roof with the hot water storage tank located at ground level or any other convenient location throughout the home. Envirosun AS solar hot water system are relatively simple in operation – when the solar hot water panels (also known as solar collectors) are able to add heat into the storage tank, a small pump is switched on to circulate hot-water from the collectors and replace it with cool water from the tank.
The circulation pumps are relatively small and silent, they also draw a negligible amount of power (less than 28 watts) that is also only used when operating or needing solar to increase the hot water storage cylinder’s temperature.
When the collectors are 6°C hotter than the water in the storage tank, the circulating pump is operated. When the differential falls to 4°C or lower, the pump is not operated. The microprocessor also uses the sensor information to control a suite of over-temperature protection modes:
if the water in the Envirosun storage tank reaches 70°C, the solar pump is not operated
if the solar collector panels temperature reaches 190°C, the pump is cycled on to control the temperature to below 185°C therefore protecting the solar panels
if the solar panels temperature reaches 200°C the pump is not operated to prevent damage
if the tank temperature has risen above 70°C and the collectors are cooler the pump is run intermittently to protect the storage tank from damage and overheating
