ENVIROSUN AS SPLIT SOLAR HOT WATER SYSTEMS

AUSTRALIAN MADE SOLAR HOT WATER STORAGE TANKS WITH SIZES TO SUIT MOST HOMES AND CLIMATES

The benefits of using the sun’s energy to heat water has been around for many decades,Envirosun have developed the most advanced split solar hot water systems in Australia. The Envirosun AS Solar Hot water range is designed exclusively for the vast Australian climate and varying conditions.

Envirosun’s AS Solar Hot water heaters are in a class of their own when it comes to performance, reliability and life expectancy. From the Australian made solar hot water storage tanks, to the best European control and pumping systems along with the extremely high solar absorption panels made from the absolute pinnacle of
solid materials copper, aluminium and brass, Australian Valve Group safety and control valves, when all this is applied together gives the Envirosun AS range of solar hot water systems the reputation it clearly deserves.

Add the generous warranties offered and the fact that Envirosun is 100% Australian owned, makes it a clear smart decision to install an Envirosun solar hot water system in your home

HOW DOES A ENVIROSUN TS PLUS SOLAR HOT WATER SYSTEM WORKS?

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.

BELOW IS A BIT OF TECHNICAL TALK ABOUT THE ENVIROSUN "AS" SPLIT SOLAR HOT WATER HEATER RANGE

ENVIROSUN SOLAR PANELS

Envirosun HS solar panels are manufactured under exclusive license by the American company call Heliodyne. They are the premier solar hot water panel makers for the USA and have been in the solar hot water industry for nearly 50 years now, since 1976.

The Envirosun HS solar panel has a STC rating that is 25-25% higher than competitors. This is determined, accredited and awarded by the Australian Government’s Clean Energy regulator.

Fact

ENVIROSUN HAVE ONE OF THE HIGHEST RATINGS FOR SOLAR HOT WATER PANELS IN AUSTRALIA

Envirosun also have a solar collector called the HA solar panel that is used in higher solar regions like North and Central Western Australia, North Queensland and Northern Territory and Northern Western Australia. These are also manufactured by Heliodyne

ENVIROSUN SOLAR COLLECTORS HAVE 7 YEARS WARRANTY

We stand behind our product with lengthy warranties for peace of mind.

The Aluminium frames and casing offer great anti-corrosion characteristics to suit all environments, full internal copper manifold and a high absorption plate along with the highest quality insulation traps the heat behind toughened glass to out perform
most major brand names like Rheem and Solahart by up to 35%.

Lightweight and Slimline, Envirosun solar hot water panels have minimal antithetical interruption to your roof

OUR HOT WATER TANKS STAY HOTTER FOR LONGER

Envirosun Cylinders are manufac encapsulated in a pressure-injected, high-density polyurethane thermal insulation. Compared with archaic insulation systems using straw, wool or fibreglass, polyurethane retains more heat and does so for far longer – and it has the added advantage of imparting structural rigidity to the assembled vessel. To find out how polyurethane is used to create a superior thermal barrier, read: our insulation.

Envirosun Systems use this mix of optimisation and over-temperature protection functions to maximise energy savings and minimise heat stresses.

RUNNING OUT OF HOT WATER IS NEVER A ISSUE WITH ELECTRIC AND GAS BACK UP BOOSTERS AVAILABLE ENSURING THE HOT WATER IS ALWAYS A PLENTY

Envirosun

Solar Hot Water Systems are equipped with electric boosters that can also have Natural or LPG gas boosters added to ensure that there’s plenty of hot-water available during the worst weather or when the demand for hot water is high. Electric elements are fitted inside our storage tanks and the gas instantaneous heaters can be installed in-line from the outlet of our systems. Both options are designed to maximise the amount of solar energy that can be collected and utilise the auxiliary in a ‘back-up’ or ‘booster’ mode only.

ELECTRICAL ELEMENT ASSISTED SOLAR

Electrical assisted systems are integrated arrangements that comprise a heating element immersed in the storage tank water, controlled by a thermostat and connected to a power-supply. Both the element and thermostat are positioned at the midpoint of the tank . With the power-supply on, if the temperature at the centre of the tank falls below 50°C, the thermostat ‘opens’ and the heating element is initiated. The element continues to operate until the mid-point of the tank rises to above 60°C. The location of the element and thermostat in an Envirosun system are designed to only allow the booster to only heat the water in the top half of the tank and to leave the bottom portion available for useful solar gain. Our solar hot water systems have the ability to heat water without direct sunlight to approximately 2 x the ambient air temperature, for instance if it is a overcast day and the outside temperature is 22 degC for most of the day, your solar should be able to easily get the water to around 44 degC, minimising the boost needed

GAS BOOSTED SOLAR

Gas boosted systems involve a continuous-flow gas water heater that is mounted separate from the storage tank. The outlet from the solar hot water system is piped as the inlet to the gas heater. If the water reaches the gas heater at a temperature below 60°C, the gas supply is opened, the spark-ignition system fires, and the gas burner operates. If the inlet water temperature is above 60°C, the gas heater does not operate. Made in Japan to the highest quality

UP TO 80% ENERGY SAVINGS

Break even time is less than 3 years

Over $8000 in energy savings over 10 years

Environmentally Friendly, Energy Saver

Check out some of the comparisons here on different heat pump hot water heater brands and the Australian Government tested and allocated STC rating, the STC is a rated saving that a hot water system has been granted after testing and approved by the
Australian Clean Energy Regulator.

The number of STC’s that are issued refers to one megawatt hour (1 MWh) of avoided energy consumption over the heat pump hot water system’s deemed life expectancy

S = R – T

where: S: STC count

R: Reference conventional system’s energy consumption (MWh over ten years)

T: Tested system’s estimated energy consumption (MWh over ten years)

Here is a graph showing savings and ratings of STC assigned to Thermosyphon solar hot water systems and the approximate percentage of power saving
compared to a conventional electric water heater in zone 3
