Are Fast Hand Dryers More Efficient

The amount of electricity used by a hand dryer is related to the power consumption and the amount of time taken to dry your hands. Some hand dryers may use more power but could still save you money.

Fast Hand Dryers are More Efficient

Your building’s electricity bill will be based on the number of Kilowatt Hours (KwH) used each month. In a busy building with lots of bathrooms, the amount of energy consumed by hand dryers can make up a considerable part of the overall cost and taking steps to minimise that use is important.

Conventional Hand Dryer Energy Use

A conventional hand dryer includes a heating element to warm air and a fan to blow the warmed air over your hands to evaporate the moisture from your skin. This means that there are two components consuming power in use.

A typical evaporative hand dryer might use 1.6KW of power and take about 30 seconds to fully dry the user’s hands. This means that the total energy use per person would be: 0.013KWH. At a price of £0.34/KWH, the cost per use would be £0.004 – this means the hand dryer could be used 226 times per £1.

Reducing Energy Costs

Jet Hand Dryers Energy Use

Jet hand dryers such as the Mitsubishi Electric Wave u02 do not need to heat the air, and because they blow the droplets of water off the skin, they can work more quickly.

In Eco mode, the Mitsubishi Electric Wave u02 consumes 490W of power and takes 15 seconds to completely dry the user’s hands. At the same £0.34 per KwH electricity price, this equates to 0.002 KWH meaning a much lower operating cost than a conventional model. A Mitsubishi Electric Wave can be used more than a thousand times for less than one pound.
