FAQs

Frequently Asked Questions

What happens if there’s not enough sunlight?

The system’s built-in electric booster ensures a continuous supply of hot water, even on cloudy days or during periods of high demand.

What are the benefits of using solar hot water?

Solar hot water systems help lower energy bills, reduce your household’s carbon footprint, and make use of renewable energy, offering an eco-friendly solution for sustainable living.

What happens if there is a problem with the system?

If any issues occur, Dux provides prompt support and repairs covered under the system’s warranty, ensuring your hot water remains reliable.

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 Electric Boosted Solar 400L.

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.
