Clean. Green. Efficient. Evacuated Tube Technology.

As we embrace the 21st century our ideals need to change. Our planet's precious resources are dwindling and we must look at clean alternative energy supplies.

The Sun can provide all the energy we require.

We at Central Coast Water Tanks recently became preferred suppliers of the Hills Esteem Solar Hot Water System, using advanced Evacuated Tube technology. This simple solution, when installed in your home, can reduce CO2 emissions by approximately three tonnes per year, which is equivalent to taking a small car off the road. At Central Coast Water Tanks we continue to supply products that use alternative energy supplies, as we believe our planet and our families are our most important assets.

Evacuated tube solar hot water systems are used in millions of systems per year. Central Coast Water Tanks is proud to be the preferred supplier of the new technology in association with Hills industries.

With the huge solar hot water rebates it is now cheaper to change to solar hot water then to change over your old hot water service.

Let Central Coast Water Tanks show you how today. Just call us on 0407 002 833

Reduce your hot water heating costs by up to 80%

Heating your household water is the major consumer of energy in most homes. Installing a Hills EsteemTM Solar Hot Water System will not only help the environment by reducing CO2 emissions, it can also reduce your hot water heating costs by up to 80%.

Solar Evacuated Tubes Solar Evacuated Tubes
Solar Evacuated Tubes

Evacuated Tube technology delivers significantly better performance than traditional absorbers on the market today. Their advanced design incorporates tubes that consist of two layers of high quality borosilicate glass with a vacuum layer between them. This vacuum acts like a thermos flask, retaining up to 97% of the thermal energy, resulting in increased efficiency. The Sun's thermal energy is then transferred to the manifold via the heat pipe located inside each tube.

The small amount of evaporative liquid in each tube is super heated by the Sun's energy and forms a vapour. The vapour rises to the top of each pipe; this heat is then transferred to the water flowing through the manifold. The heated water is then returned to the tank.

The cylindrical design of the tubes ensures effective collection of the Sun's thermal energy throughout the day.

Hills Solar Evacuated Tubes are frost tolerant and have passed the AS/NZ 2712:2007 Standards for both hail and freeze resistance. Hills Esteem Solar Hot Water Systems have passed the freeze test to -15° C without the need for a heat exchanger or glycol.

Stainless Steel Tanks

Hills Esteem Solar Systems use stainless steel tanks which have a natural oxide barrier to corrosion. Stainless steel tanks are tough, durable and lighter than their equivalent vitreous enamel mild steel tanks. The tanks are of a high quality and offer a 10 year warranty.

Gas and Electric Boosting

When radiant heat is low and there is cloud cover or rain, Hills Solar offers a choice of gas or electric boosting to heat the water to your desired temperature.

Hills Esteem Gas Boosted Solar Systems use Bosch continuous flow boosters, available in both 21e, which will deliver up to 21 litres of hot water per minute, or the Bosch 26e, which will deliver up to 26 litres of hot water per minute on a low solar gain day.

Hills Esteem Electric Boosted Solar Systems ensure the water is maintained at 60° C. The system comes with a standard 3.6kw bottom-heating element; however, this can be changed to a 2.4 or 4.8kw element to conform to different State regulations. Clever positioning of the element ensures you will have a full tank of hot water available.

Some States may offer a lower tariff on hot water heating.

Renewable Energy Certificates (RECs)

RECs are a form of currency created by the Federal Government under the Renewable Energy (Electricity) Act 2000 and are used to demonstrate compliance with the requirements of the Government's Mandatory Renewable Energy Target (MRET) scheme. Hills Esteem Solar Systems qualify for these generous Government Rebates (conditions apply). There are 4 Australian zones which will determine the amount of RECs per system. Some State Governments and local Councils also offer generous rebates on Hills Esteem Solar Systems. This can mean a rebate of up to a third of the cost of your Hills Esteem Solar Hot Water System.

For a complete list of RECs zones by postcode please visit www.orer.gov.au

When checking the RECs listing, please note the systems are listed under the manufacturer Endless Solar.
