AOS Bath Recommends Renewable Energy Water Heaters

Are you considering a heating solution for your home or project in Singapore? At AOS Bath, we recommend going green with heat pumps or solar heaters.

These innovative renewable energy systems offer a range of benefits that make them an excellent choice for homeowners.

AOS Top Pick: Heat Pump Water Heaters

Heat Pumps are designed to be incredibly energy-efficient. They work like air conditioners in reverse, using only 25% energy to give you a full tank of hot water. 

A Heat Pump will reduce your heating bills by 80%

Heat pumps transfer heat from the outside air to your heater, providing hot water at a fraction of the running cost of an electric heater.

The Big Secret:

Heat pumps work better in Asia.
Much better than solar water heaters.

Solar water heaters also use renewable energy. 

While heat pumps use air heat to create hot water, solar heaters use the sun’s heat to heat their tanks.

But solar operates at only 50% efficiency because of Singapore’s heavy cloud cover.

In Singapore, Heat Pumps Have No Downtime.

They work when it is cloudy.

They work when it is hazy.

They work when it rains.

Heat pumps have a high efficiency of 80%

We specialise in large solar heater conversion to heat pumps.
