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.
