The Details

Key Features

400L Ground Mounted Solar Tank with 3 Roof-Mounted Collectors

The Dux Ecosmart 400L system features a large ground-mounted solar tank, ideal for medium to large Australian households. Its generous 400-litre capacity ensures there is enough hot water for multiple showers, baths, and household tasks without interruption. With three high-efficiency roof-mounted solar collectors, the system captures maximum solar energy throughout the day, converting sunlight into heat. The triple-panel setup enhances performance, delivering reliable hot water even during cloudy conditions.

Multi-Temperature Tank Sensors

Advanced multi-temperature tank sensors optimise solar gain while preventing overheating. By monitoring temperature variations within the tank, the system adjusts heating to operate at peak efficiency, ensuring consistent performance and energy savings.

6-Star Continuous Flow Gas Boosting

A 6-star continuous flow gas booster provides a reliable backup hot water supply during periods of low solar energy. This ensures instant hot water availability whenever needed, offering convenience and peace of mind for your household.

FAQs

Frequently Asked Questions

Can the system work in cloudy weather?

Yes, the Dux Ecosmart is designed to operate efficiently under various weather conditions. The gas booster activates automatically to supply hot water during cloudy days or winter months when solar output is reduced.

What are the environmental benefits of this system?

By harnessing renewable solar energy, the Dux Ecosmart reduces greenhouse gas emissions and lowers your household’s carbon footprint, providing an environmentally responsible hot water solution.

Can the Dux Ecosmart be installed on my roof?

The system can be installed on most roofs, though specific placement depends on your property’s layout and structure. A qualified installer should assess your site to ensure optimal solar exposure and performance.

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 400L Gas 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.
