Rinnai Electric and Solar Hot Water Systems
Solar Hot Water Systems Gold Coast & Brisbane
Replacing an electric storage tank with Rinnai solar hot water system can reduce electricity consumption, Running cost and environmental impact by 2/3 40% of typical household electricity usage for water heating, Therefore a Solar hot water heater can reduce the overall electricity use by 75%.
Australian electricity is predominately generated using non renewable and dirty coal fire power stations. As well as electricity they produce carbon dioxide emissions, ash, particles and waste heat, while consuming vast quantities of water and non renewable coal.
RINNAI Solar hot water system reduces the need for electricity and are part of many major energy reduction programs.
Solar hot water systems also offset electricity just when it is needed most:
Summer that is when the air conditioners are running, loading up the electricity network. With rising electricity cost future electricity bills will only increase. One method to reduce future electricity bills is to use less electricity with solar water heater.
Will I Get Solar Gain In Winter?
Solar gain is available during the day throughout the year, even cloudy days can deliver more solar gain. A clear winters day may sometimes deliver more Solar energy than a cloudy day.
- Clear & sunny – high solar contribution
- Clear cold – reasonable contribution
- Overcast warm – reasonable solar contribution
- Overcast & cold – low solar contribution
What Types Of System Are Available & What Are The Differences?
Close couple systems have storage cylinder above the solar collectors all located together on the roof. Close coupled systems rely on the thermo-syphoning principle. Hot water rises because it is less dense to circulate the water through the collectors and then to the storage tank without the need to consume energy.
Split Systems is where the storage cylinder and the solar collectors are split and installed separately A solar control unit ensures the water circulates between the solar collectors and the storage tank. This transfers heat from the collectors to the water in the tank if enough heat is available from the sun.
