Solar Water Heaters

Roof

The ultimate solar thermal solution.

Balcony

The first solar solution for apartments.

A solar photovoltaic (PV) module is an
array of cells which convert solar
radiation into direct current electricity.

Solar water heaters are not photovoltaic calls.

They both collect solar radiation but for different purposes.

In solar heaters, water is continually heated as it flows through solar collectors and back into the tank.

Solar energy is free and renewable.

Each of our solar systems come complete with an electrical back up should weather conditions not be favourable.

Solar tubes perform better than flat panels in cloudy conditions.

The vacuum in the glass tube allows the tube to retain a high percentage of collected heat.

Frequently Asked Questions About Solar Water Heaters

Yes, solar water heaters can fit in landed homes in Singapore.

Do note that solar heaters only have a heating efficiency of around 50%. For a better renewable energy solution in Singapore, choose heat pumps. Heat pumps operate at a higher efficiency of 80%.

The average heater in Singapore lasts only 3 to 5 years.

AOS heaters have been proven to last well over 10 years.

This is due to the Blue Diamond Tank technology, patented by A. O. Smith in the 1920s. Longer lifespans are what make A. O. Smith the #1 Water Heater in USA.

Most solar heater removals involve a crane, and this costs around +$450. The good news is, most homeowners can skip this step if they are not doing a solar to solar replacement.

It is possible to drain the water from the existing solar heater tank and install the new heater close by.

The energy that PV cells generate are good for light usage (say 100-800W as an estimate) at home. They can power up light bulbs. On average, PV cells do not generate enough electricity to power up an electric water heater of 3000W.

If you want to explore using PV cells to power your heater, use a heat pump heater. Compared to an electric heater, heat pump heaters only consume 200-500W.
