Frequently Asked Questions
What makes the Rheem Hiline® 52L300 SS Solar Water Heater different from other systems?
The system features a robust stainless steel cylinder for enhanced corrosion resistance and durability. The direct heating process maximises solar energy utilisation for efficient performance.
How does the booster work on cloudy days?
When sunlight is insufficient, the booster activates automatically to maintain a consistent hot water supply. Choose between an electric element or a 6-Star continuous flow gas booster.
Is the Rheem Hiline® 52L300 SS Solar Water Heater efficient in heating water?
Yes. Direct heating through the solar collectors optimises energy capture, allowing the system to reach the desired temperature rapidly while minimising reliance on external energy.
How does a solar hot water system work?
Roof-mounted solar collectors absorb heat from the sun and transfer it to the water in an insulated storage tank. An electric or gas booster tops up the temperature on cloudy days so you never run out of hot water.
Is there a government rebate for solar hot water systems?
Yes — eligible solar hot water systems qualify for Small-scale Technology Certificates (STCs), which reduce the upfront cost. SunCity Hot Water will confirm your eligibility and handle the paperwork.
How long do solar hot water systems last?
A well-maintained solar hot water system can last 15 years or more, with the tank and collector panels covered by manufacturer warranties.
How much do solar hot water systems cost?
Solar hot water systems cost more upfront than electric, but government STC rebates and much lower running costs offset this over time. Call SunCity Hot Water on 1300 728 122 for an all-inclusive quote on the Rheem Hiline® 52L300 SS Solar Water Heater.
What size hot water system do I need?
As a guide, 1–2 people suit 125–160L, 3–4 people (a family of four) suit 250–315L, and larger households suit 400L. Continuous-flow gas units are sized by hot water flow rate instead. SunCity will help size the right system for your household.
