Electric and gas heaters consume 3000 watts of power or equivalent.
Heat pump water heaters use 210 watts.
Heat pumps of the past
Heat pumps of the past used to be huge and suitable only for commercial use. Think.. 2000 litre water tanks on the roof of a hotel.
A. O. Smith invented the smallest heat pump in the world, suitable for apartments.
Micro heat pumps
The smallest heat pump in the world has a capacity of 60 litres. With this new invention, the energy saving heat pump technology is now accessible to all homeowners.
Heat pumps: three times more efficient than electric heaters
With the same amount of electricity, heat pumps produce three times more hot water than electric heaters when they absorb free air heat from the surroundings.
Fully automated smart heater
Your heat pump is a smart water heater which goes into energy saving mode when not in use. Activate the automatic timer (AES) and the system will memorize your family’s bathing patterns over twenty-one days.
AOS heat pumps: Ranked #1 efficiency
The latest heat transfer coils wrapped outside the tank make AOS the top efficiency heat pump in USA and China. They are also the safest with zero chances of refrigerant leakage into water.
Number 1 water heater in USA
A. O. Smith is America’s top water heater due to their successful manufacturing process of Blue Diamond tanks that can last at least 10 years. Today, they are the largest water heater manufacturer worldwide.
100% fully-owned robotic plants
To maintain high quality control, A. O. Smith Corporation fully owns every of their 21 plants worldwide. They are the only manufacturer with the technology to employ robotics over 95% of their production line.
Established in 1874
A. O. Smith Corporation has led the industry in the development of advanced automated technology, manufacturing car frames for Ford and Cadillac in the 1900s. The consistency of their processes have been unparalleled in the last 100 years.
Are heat pumps suitable for HDB?
Absolutely. Micro heat pumps easily fit into all apartments and this includes HDB units. Popular installation locations are in the bathroom or at the service yard where the heat pumps can draw in plenty of free air heat.
Which heat pump size is good for a bathtub?
Heat pumps are great if you love long showers or if you are a heavy duty bathtub user. The more you use, the more yousave.
With the 1.5 meter bathtub shown here, an 80 lit heat pump is used. Have a bigger tub? Click the link below to find out more.
Can heat pumps be installed above a false ceiling?
Yes, micro heat pumps can be installed above a false ceiling and you can disconnect the control panel attached to the heat pump, fixing it to the wall or the ceiling.
What is the difference between a heat pump and a digital heater?
The difference lies in the level of technology. Heat pumps can operate in two modes. High performance digital modes or the energy saving heat pump mode.
