System Location
- Solar hot water systems require north-facing placement without shading for maximum solar gain.
- Gas storage systems require adequate outdoor ventilation per standards.
- All systems should install as close as possible to bathrooms, kitchens and laundry for minimal pipe heat losses.
Water Connections
- Cold inlet and hot water outlet connections must isolate and seal completely without leakage or faults.
- Mixing valves must be precision-adjusted to 50 degrees Celsius to prevent scalding risks.
- Pressure limiting valves should install if water pressure exceeds 500 kPa along with expansion control valves on closed water systems.
Gas & Electrical
- Only licensed professionals should undertake specialized gas fitting and electrical work which must strictly meet all Australian standards.
- Isolating valves should be included for ease of maintenance.
- Lightning protection may be advisable for solar thermal systems.
Paperwork & Compliance
- All rebates, certificates, approvals and required paperwork should be completed by the installer to guarantee compliance.
Maintenance Tips for Peak Efficiency
Ongoing system maintenance is vital for optimal performance, safety and longevity. Here are some key efficiency tips:
- Schedule electric or solar electric hot water heating to occur overnight using off-peak tariffs
- Add water-saving showerheads and tap aerators to reduce wasted hot water
- Insulate exposed piping to minimize heat losses in transit
- Limit showers to 4 minutes with mild temperatures
- Immediately repair any leaking taps, valves or pipes
- Inspect condition and service relief valves annually as a safety measure
- Check sacrificial anodes and replace corroded rods in storage tanks to prevent rust
- Clear dust buildup on solar collectors over summer or during bushfire smoke events
- Have professionals service the system as per the manufacturer’s recommendations
