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
The Envirosun AS smart control system is absolute state of the art with a LED screen to tell you exactly whats going on inside our weatherproof cover
Envirosun AS solar hot water systems have a size to suit most homes

Envirosun solar hot water systems are made of the world most advanced solar products
The Envirosun AS Storage Cylinder
250 litre - 315 litre - 400 litre

Durable pressure vessels
Our storage cylinders are built to last
Envirosun AS solar hot water tanks are Australian Made from high-strength materials especially suited to operating in high-temperature, high-pressure applications which can otherwise be very corrosive. Vitreous enamel lined cylinder and anode protection to provide for a long life
All Envirosun As solar hot water tanks are manufactured in Australia
Our hot water tanks stay hotter for longer
Envirosun storage cylinders are encapsulated in a pressure-injected, high-density polyurethane thermal insulation to provide a extended time of heat retention
Our storage cylinders deliver hot water faster
Our storage cylinders deliver hot water faster. Envirosun solar hot water systems are rated to operate high water pressures that are near to that of the mains water supply. Unlike low pressure hot-water systems, you can enjoy plenty of hot-water from more than one outlet at the same time.
Envirosun systems use this mix of optimisation and over-temperature protection functions to maximise energy savings and minimise heat stresses

Envirosun have the absolute latest and proven technology in the AS range of solar water heaters, highest quality European made solar controllers, pumps and sensors are only used
