Frequently Asked Questions
What are the benefits of choosing a solar hot water system?
Solar hot water systems reduce energy bills, lower your household’s carbon footprint, and may qualify for government incentives such as Small-scale Technology Certificates (STCs). Electric boosting ensures a reliable hot water supply even during cloudy days or periods of high demand.
Can the Dux EcoSmart system be installed in any home?
The system is suitable for most homes with adequate roof space and sunlight for the solar panels. A licensed installer can assess your property to determine the best placement for optimal performance.
What should I do if I experience issues with my hot water system?
If any issues arise, contact a licensed technician for assistance. Prompt assessment and maintenance will ensure your system continues to operate efficiently and remains covered under warranty.
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 Dux EcoSmart 315L Electric Boosted Solar Hot Water System.
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.
