Dux have a range of solar hot water heaters with the solar collector panels on the roof and the solar storage tank on the ground.
With the Dux Sunpro range of solar water systems you can choose from a back up element on continuous or off-peak electricity. Alternatively you may want a gas continuous flow booster. For houses with limited roof area there is the Dux Solarone with a single high efficiency solar panel.
Ensure your Dux solar hot water system is installed by a qualified plumber to get maximum hot water for your needs.
