Energy Efficient Solar Hot Water Products

At Red Circle Solar, we sell high quality solar hot water systems through a specialist distributor network at competitive prices. We aim to make the whole process as easy and as flawless as possible, providing training, consultationand support to both the distributor network and the retail consumer.

Solar hot water is our specialty Red Circle Solar designs and imports evacuated tube solar hot water systems and solar hot water accessories that are cost effective and versatile, suiting almost any application. We specialise in stainless steel close coupled systems; Duplex stainless steel split systems; energy efficient water heaters and CO2 heat pumps, so no matter what your solar hot water requirements are, we can tailor a package that will suit your needs.

Close coupled solar hot water: The tank and evacuated tubes are both on the roof and the heat from the evacuated tubes thermosyphons into the tank, removing the need for a circulation pump. Combining a low-pressure tank with a mains pressure domestic water supply, this style of system is easy to connect to a wood fire without compromising on water pressure. The 30-meter copper heat exchange coil operates at mains pressure, and extracts the heat from the tank as it is being used. The lack of moving parts in the design makes this our most cost effective solar hot water system.

Split system solar hot water: The solar hot water storage tank is on the ground and the evacuated tube solar collector is on the roof. The heat from the solar collector is pumped back to the tank, which is controlled and can be boosted by an electric element, gas booster or used as a pre heat to existing hot water systems. Our split system tanks are made from 2205 Duplex stainless steel and come in sizes ranging from 200ltr -500ltr.

Sanden heat pumps (C02). Red Circle Solar is a loyal dealer of Sanden Heat Pumps-energy efficient water heaters for Melbourne and the sorrounding areas. With a COP (coefficient of performance) of 5, the Sanden Heat Pump is the most efficient heat pump available in Australia, using only 900 watts to generate 4500 watts of heat! Magic? Almost, but no. The efficiency comes from the use of a compressor that takes the ambient heat from air, and passes through a CO2 heat exchanger, which compresses the CO2 gas. As the pressure of the gas goes up, the temperature of the gas increases. The heat is then transferred to the water stored in the tank ready for use in the home or business. Perfect for coupling with an existing PV solar power system.

Solar hot water accessories: Red Circle Solar also sells many other solar hot water products, including titanium heat exchangers; evacuated tube solar collectors; pumps; controllers; hydronic buffer tanks; and solar specific instantaniuos gas boosters.

Wood fire boosted solar hot water: Red Circle Solar specialises in wood fire boosted hot water. It is possible to use a wood fire and solar hot water to provide 100% of your hot water needs without any electric or gas boosting. We also sell hydroninc buffer tanks that have heat exchange coils so you can combine hydronic heating with domestic hot water.
