Bandanna Earth Energy is excited to provide customers with a Solar Hot Water Offer which brings great savings on their energy costs and the chance to further reduce their green footprint.
The Solar Hot Water Program is whereBandanna Energy provides energy efficient products such as Solar Hot Water to our Customers at no up-front cost, we merely charge a sustainability levy.
Solar Hot Water can reduce your water heating cost by 80% of a household’s electricity bill. According to the Australian Government, a solar hot water system can save between $300 and $700 every year off electricity bills.

Solar Hot Water Installation Considerations
There are six major factors to consider when selecting the solar water heater installation location;
- For optimum performance the solar collectors need to face the equator. Installations on angles of up to 45° away from the equator do not have a major effect on the annual solar output. Consequently, roof locations which face less than 45° away from the equator are acceptable. If the collectors are installed with an east facing bias then the best solar input is achieved in the morning. If there is a west facing bias the best solar input is in the afternoon.
- Careful site inspection is required to ensure the selected location is not subjected to shading from adjacent trees or buildings throughout the day, but particularly between 9am and 3pm – the highest solar input times.
- The storage tank should be located as close as possible to the location which uses the most hot water, usually the bathroom or kitchen. This is to reduce energy losses which may occur if the pipe-work between the solar water heater and the point of use is too long.
- The collectors should be located as close as possible to the storage tank location. This is to reduce energy losses due to long pipe work between the collectors and storage tank. For optimum performance the collectors should be no more than 20 m of pipe run from the tank. (40m total – send and return).
- To achieve optimum performance the collectors should be installed on a roof pitch of greater than 8° and less than 30°. If the roof pitch is less than 8°, the system will require a mounting frame to increase the pitch. Installations below 8° do not circulate effectively and the collector glass will not self-clean during rainy periods.
- The roof system must be carefully inspected to ensure it can support the systems weight once it is filled with water. If the roof cannot support the load, additional bracing must be installed before the solar water heater is installed.
Conergy AS 250L Split Level System
Bandanna Earth Energy proposes the Conergy AS 250L or AS315L Split Level System. The Split System consists of roof mounted collector panels and a ground mounted hot water tank. The water is circulated between tank and collectors by a small pump which is regulated by the Conergy Smart Solar Controller.
Conergy AS250L Features:
-
Vertical tank increases efficiency
-
Advanced top element configuration for maximum solar gain
-
Durable and reliable in all conditions
-
Tank at ground level is aesthetically more pleasing
-
Smart controller electronics avoids boiling and over heating
-
Available with either gas or electric boosting
-
Tank can be located close to main area of hot water needs such as bathrooms – meaning instant hot water
