Active Solar (AS) Hot Water System

Envirosun’s Active Solar ‘AS’ range of pumped or active solar hot water systems offer greater flexibility, improved aesthetics and higher capacity, along with maximum efficiency and reduced energy costs. Only the solar collectors are installed on the roof, harnessing energy from the sun and transferring it to a ground-mounted storage tank. The tank can be sited indoors or out, in any convenient or out-of-the-way location.

The operating principle is simple – when the 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. Once the tank is full of hot water, the pump is switched off, but ready for the next cycle.

While pumped systems have been around for many years, modern electronics and materials have brought improvements in both function and reliability. Today’s Envirosun AS systems adopt many of these technological advances and blend them with our collector technology to create a range of high-performance active solar

hot water systems that maximise solar absorption and storage, whether you live in a low or high radiation area.
