Heat Pump Technology

How do Water Heat Pumps Work?

Heat Pumps are the ultimate energy efficient water heaters in tropical climates like Singapore. They absorb hot ambient air and use it to heat water.

They can save up to 75% of energy, or around $600/year on utility bills.

Heat pumps are at least 3 times more energy efficient than electric heaters because
they heat water using a different technology.

Disadvantages of Solar Heaters

Solar heating is an old technology which has been used since the 1900s. Unlike heat pumps, solar heaters require specific conditions to operate.

 Rainy days
 Hazy conditions
 In the evening

When these conditions are not met, back up heating elements in solar heaters will kick in and they will operate just like regular electric water heaters, which are not energy saving at all.

Solar heaters in Singapore are estimated to save around 50% of energy instead of their intended 100%.

Advantages of Heat Pumps

Heat pumps are a newer technology which has been used since the 2000s. They work well within the ambient temperature range of 7℃ to 45℃. In Singapore, heat pumps can run at high efficiency at every time of the day, the whole year round.

Heat pumps do run on electricity, but their energy consumption is exceedingly low. They are estimated to save around 75% of energy and are more affordable and easier to maintain than solar heaters.

Heat pumps are also more efficient than solar heaters especially in cloudy, tropical climates like Singapore.

Cloudy conditions in Singapore are common and they affect the performance of solar heaters

Clear skies allow solar heaters to operate at maximum efficiency, but these are rare occurrences in Singapore

Because of their high efficiency, heat pumps are widely used in hotels and clubs in Singapore. Shown above, St. Regis Singapore.

Advancements in Heat Pump Technologies by A.O. Smith

Heat pumps of the past are usually large and more suitable for commercial use. Their capacities generally range from 300 litres and above.

Just recently,  invented the smallest heat pump in the world, suitable for apartments.

PATENT ZL20120224011.5

The smallest heat pump in the world has a capacity of 60 litres.
Home owners in Singapore can now take advantage of this energy saving system.
