ECOSMART ELECTRIC BOOSTED SOLAR 400L 3 PANEL | Hot Water Systems | Dux Hot Water



If you’re aiming to reduce your carbon footprint, or simply tackle your growing energy bill, choose an EcoSmart solar water heater. EcoSmart uses the latest European solar technology to capture the sun’s energy and heat water in roof mounted, high performance solar collectors. This water is pumped and stored in a highly insulated, Australian made solar tank, ready to use when you need it.

Electric boosted models come fitted with a mid-mounted element, ensuring hot water is available on cloudy days or in times of high demand. Connect this to an off-peak electricity tariff for even lower running costs.

Is solar suitable where I live

Solar water heaters can be prone to frost issues when installed in areas with very low ambient temperatures. All Dux products are fitted with pumped circulation, and optionally anti-frost valves to prevent frost damage from occurring. These may still not be able to prevent water in the collectors freezing during very cold conditions.
