Enhancing Your Home with Envirosun AS315 40

Enhancing Home with Envirosun AS315 40

The Envirosun AS315 40 system offers:

  • Functionality and aesthetics

  • Modern and sleek appearance

  • Integration with a wide range of home architectural styles

  • Space-efficient design

  • Flexibility in terms of installation, making it less intrusive and maintaining the aesthetic of the home’s exterior.

Curb Appeal and Property Value

The Envirosun AS315 system features low-profile solar collectors installed on the roof, with the storage tank at ground level. This design offers an aesthetically pleasing solution that can improve the property’s visual appeal.

For properties with flat or skillion-style roofs, the solar hot water system’s collectors can be designed to have minimal visual impact, thereby potentially enhancing the curb appeal of the home.

Space and Placement

Achieving optimal performance from the Envirosun AS315 40 system requires strategic placement. The tilt angle of solar collectors should be set by adding or subtracting 15 degrees to the latitude of the location to maximize sun exposure. Solar hot water system collectors ideally should be installed on the north-facing section of the roof, within a 45° range east or west of true north for optimal sunlight capture.

Adequate unshaded roof space is essential for the solar collectors of the hot water system, which benefits households that want to leverage free solar energy for heating water. For a discreet aesthetic, adjustable collector stands can be utilized to lessen the visual impact of the solar collectors from street level.

Making the Switch: Transitioning from Electric to Solar Hot Water

Making the switch from an electric hot water system to a solar one like the Envirosun AS315 40 can significantly transform your residential energy consumption. The process includes:

  1. Decommissioning your old electric hot water system.

  2. Removing the old system.

  3. Preparing the installation area for the new solar hot water system.

  4. Professional installation to ensure optimal performance of the Envirosun AS315 40.

Trained technicians can provide advice and support for any queries during the switch to solar hot water. And remember, while there is an upfront cost in purchasing and installing the Envirosun AS315 40, the long-term energy savings make the investment worthwhile.

Assessing Your Current Hot Water Needs

Assessing your current hot water needs is a critical step before transitioning to a solar hot water system. For a household with 5-6 occupants, the Envirosun AS315/40SE Solar Hot Water System is generally suitable, with the rule of thumb being to allocate approximately 50 liters of hot water per person per day. The typical water heating system in Australia is a storage/tank system that can be paired with solar; it usually relies on solar energy and uses grid energy as a supplementary source when needed.

When integrating solar PV with hot water heating, it’s important to ensure that the water tank’s heating element wattage matches the solar system’s peak output. A tailored solar hot water system configuration is essential for meeting individual demands and can take into account factors such as location, water usage, and budget constraints. Solar diverters or timers may be installed to optimize hot water heating moments using excess solar energy, depending on the home’s specific energy tariff and metering setup.

Factors to consider when evaluating solar hot water needs include:

  • The type of residential water heating

  • Energy tariffs

  • Controlled load circuits

  • The size of the solar hot water system

  • Water heating schedules

Planning and Execution

To avoid unexpected costs, homeowners should secure a detailed quote encompassing all necessary components and services before installation. This quote should outline the technical specifications of the system, the timeline for installation, and a comprehensive cost breakdown.

The transition process may involve scheduling the installation to minimize disruption to the household’s hot water supply. Planning ahead ensures a smooth transition and allows the household to adjust to the new system without any inconvenience. With the right planning and execution, switching to a solar hot water system can be a seamless and rewarding experience.


Investing in an Envirosun AS315 40 Solar Hot Water System is not just about harnessing the power of the sun; it’s about making a long-term commitment to energy efficiency, cost savings, and environmental sustainability. With the right system and the right installer, you can enjoy consistent hot water supply, lower energy bills, and the satisfaction of reducing your carbon footprint. So, are you ready to embrace the future of hot water systems?
