A. O. Smith Roof Solar Water Heater

The ultimate solar thermal solution for environmentally conscious homeowners.

Solar Collector Technology

For optimal heat absorption and efficiency, A. O. Smith has customized solar technology for Asian climates.

Leading American Technology

A. O. Smith has been refining water heating technology for the last 140 years. Every A. O. Smith heater is equipped with cutting edge, patented technology. Other heaters may look like A. O. Smith heaters but they do not work the same way.

Built to Last

A. O. Smith’s patented Blue Diamond formula makes its water heater tanks the toughest and most durable tanks in the market.

The longest lasting heater in the world was made by A. O. Smith.

No OEM Factories

Other manufacturers use OEM factories so they can give you cheaper products, but every A. O. Smith water heater and its components are manufactured in-house.

3 Year Full Warranty

Other heaters only provide full warranties for one year. All A. O. Smith products are fully guaranteed for 3 years – parts and labor, making us the longest water heater warranty provider in Singapore.


Patented vacuum casing ensures enhanced collection efficiency.

Curved tubes allow for thermal absorption from a greater range of sun angles.

Unlike solar panels produced for other regions, this solar range fits tubes independently into the header pipe.

Individual tubes can be removed and replaced without having to decommission the entire system.
