Rinnai Evacuated Tube Solar Hot Water System
Rinnai has over 30 years experience in designing and manufacturing hot water systems. Rinnai’s new evacuated tube technology offers high efficiency tubes to absorb the maximum available solar energy.
An evacuated tube solar hotwater system is a split system where the storage tank is ground mounted and the solar collector tubes are installed separately on the roof.
The system offers excelent frost protection able to withstand temperatures as low as -12 degrees.
The tanks are available in both VE (vitreous enamel) and stainless steel options.
Apricus – Solar Hot Water Evacuated Tubes System
The Apricus evacuated tube system is the most efficient solar hot water collector available on the market. The technology works with a vacuum between two layers of glass tubing, similar to a coffee thermos. This insulates the system from the outside air temperature allowing much more efficient water heating even with the air temperature being cold. Infact this system can still produce heat in -20 degree outside temperatures. For most family homes a 30 tube system on the roof coupled with a 315ltr tank on the ground is the best water heating option.
Stiebel Eltron – Solar Hot Water Heat Pump
Stiebel Eltron has been developing innovative solar hot water solutions for over 85 years. Stiebel Eltron products are made in Germany and naturally built to the highest standards.
Heat Pump technology is basically utilizing the same technology in reverse cycle air – conditioners but instead of heating air it heats the water contained in up to a 300 liter tank. The heat pump requires no panels on the roof and is therefore a good solution if roof access is limited.
the Stiebel Eltron WWK 300A Heat Pump was specifically designed for Australian conditions to provide reliable and energy efficient hot water.
Rinnai Close Coupled VE Tank
Rinni close coupled systems are the most familiar design in Australia, with a tank installed on the roof adjacent to the solar collectors. Due to the thermo-syphoning effect the system works without pumps or complicated value systems and moving parts. There is a built in TA valve(thermal arrestor valve) that reduces water loss in summer months.
Vitreous enamel tanks are a mild steel tank that has the inside coated with a ceramic product that is heated in a kiln to solidify into a glass like skin, called vitreous enamel. This protects the mild steel from corrosion. A sacrificial anode is used to protect the mild steel from any corrosion that may occur in small areas where mild steel is in contact with water.
