Key Features
250L Ground Mounted Solar Tank With 2 Roof Mounted Collectors
The Dux EcoSmart features a 250-litre ground-mounted solar tank, ideal for medium to large households. Its sturdy construction ensures long-lasting durability and reliable performance. Two roof-mounted solar collectors efficiently capture solar energy throughout the day, providing a consistent hot water supply even during periods of variable weather.
Multi-Temperature Tank Sensors
The system is fitted with multi-temperature sensors that monitor water temperatures at different levels within the tank. This optimises solar heat capture and reduces the risk of overheating, improving energy efficiency while extending the lifespan of the system.
Mid-Point Electric Boosting
The innovative mid-point electric booster provides an extra 120 litres of hot water when solar input is insufficient. This ensures households have adequate hot water during cloudy days or periods of high demand.

Frequently Asked Questions
What is mid-point electric boosting, and how does it work?
Mid-point electric boosting provides an additional 120 litres of hot water by heating water electrically when solar energy is insufficient, such as during cloudy days or periods of high demand. This ensures a continuous supply of hot water for your household.
How does the Dux EcoSmart contribute to environmental sustainability?
By harnessing solar energy, the system significantly reduces reliance on fossil fuels and lowers greenhouse gas emissions associated with water heating. This supports a more sustainable and energy-efficient approach to running your home.
What should I do if I experience a problem with the system?
If any issues arise, contact a licensed plumber or authorised Dux service agent for inspection and repair. Regular servicing and professional maintenance help maintain the system’s efficiency and prolong its lifespan.
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 250L.
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.
