Eurosun HP Solar 300L

300L HP Solar

Key Features

TickLonger Tank life: The enamel coating is made from titanium blue enamel powder that meets the Australian Watermark certification requirements.

TickTemperature Control: The open circuit system is equipped with a Thermosiphon Arrestor Valve (TRV) to avoid exceedingly high temperatures during periods of high solar radiation, which guarantees over heating temperature protection, because it restricts the hot water flow to the tank when it has reached a sufficiently high temperature.

TickStrong Anode Rod protects the water heater tank against corrosion.

TickHigh performance Solar Collector. The sputtered selective surface maximises the absorption of solar energy. The solar collector is all aluminium outer casing, giving excellent corrosion resistance and proven long life.

TickAll valves fitted during installation are Australian made or designed.

TickThe system comes with an electric booster to assist in times when there are prolonged periods without sunlight.

TickLow maintenance operation.

TickEligible for Government rebates.

TickOptional components at additional price:

  • Cyclone resistant mounting frame – recommended in areas prone to cyclones and very strong wind conditions.
  • Gas booster – based on customer preference.
Titanium Blue

This confidential formula is acid-corrosion resistant, alkali corrosion resistant, temperature rapid change resistant, water tight and hot water corrosion resistant. Other technical indicators of enamel are in line with the German DIN4753-3 standards.


Extremely thick and high intensity thermal protection performance.


The shell adopts high efficiency, heat galvanised plate and an outdoor painting process. It has the features of anti-corrosion and is rust proof to help ensure prolonged service span.

Eurosun’s solar rooftop open circuit* system has highly efficient solar collectors fitted to the roof to absorb the solar energy during the day to heat water. It works on the simple scientific fact that hot water rises. The heated water is passed through and stored in an insulated tank, which is also mounted to the roof.

On overcast days, an in-tank heating element (booster**) will activate itself and heat stored water when temperatures drop below a set point.

*Open circuit systems are better used in locations where the ambient temperature never falls below freezing point (0 to 32 °F).

**Two types of boosters are available: electric or gas. They act as a backup for those days when the sun is not shining or if usual demand is exceeded. This ensures your home always has a continuous flow of hot water to be used.
