Solar Hot Water - FAQs Q. What Savings may I expect from a solar hot water system? A. You may achieve savings for energy consumption for hot water generation between 50-90% compared to gas or electric storage hot water systems when your solar hot water system is sized and installed correctly. Savings of 50% to 90% shown are based on Australian Government approved TRNSYS simulation modeling. Savings and incentives will vary depending upon your location, type of Edwards System installed, orientation and inclination of the solar collectors, type of water heater being replaced, hot water consumption and fuel tariff. Maximum financial savings off your hot water bill are achievable when replacing an electric water heater on continuous tariff. Q. When is the best time to go solar? A. The sooner you install a solar hot water system, the sooner you will start saving money on your water heating costs. If your current hot water system is at least 10 years old then it is a good time to obtain a quote for a solar hot water system. That way, you shall save time and avoid any panic when your old hot water system fails. Q. What is the life expectancy of a solar hot water system? A. Edwards stainless steel solar hot water systems are designed and manufactured right here in Australia for our harsh Australian conditions. It offers you peace of mind, knowing the system has been developed to last for years in our tough climate. Q. What are the benefits of stainless steel? A. Stainless steel has a higher tensile strength than mild steel, enabling the manufacture of stronger, lighter storage cylinders. As no sacrificial anode is required, maintenance costs are reduced and the stored water is free of the residue of dissolving anodes and cylinder corrosion. Q. How hot does the water get in a solar hot water system? A. Water from a solar hot water system can easily rise above 70deg C. At this temperature it takes less than half a second to cause a severe scald to a child. There are regulations in place requiring the installation of hot water Tempering Valves on all hot water heater installations to ensure safety. Q. How long does it take to install my new solar hot water system? A. The average installation will take from 5 to 8 hrs. Q. Does stainless steel rust? A. Stainless steel is one of the most durable of materials where rust stains are generally stains deposited by other items coming into contact. Stainless steel is the material of choice for the most demanding of marine and out-door environments where corrosion is at its most extreme. |
