Take The Test

Is your school wasting energy with inefficient hand dryers?

In an average school, where hand dryers are used more than 500 times each day, energy usage can be considerable, but choosing a more efficient dryer could reduce costs by more than 60% as well as having a major impact on C02 emissions because of wasted electricity.

As schools look to make their budgets go further and move towards a net zero future, updating hand dryers can help to achieve both goals.

How Efficient are Hand Dryers

Conventional hand dryers will often consume large amounts of power to run.  The design of an evaporative hand dryer (where warm air is blown slowly over the hands) requires both a fan and a heating element to work.  Using such a dryer can take upwards of 30 seconds.  Most commercial hand dryers will use between 750w and 1000w to operate.

In a typical school, where hand dryers may be used more than 500 times per day, this can mean incurring annual running costs of around £159.  

The more efficient Mitsubishi Electric Wave i01 hand dryer uses a fast-moving jet of air to blow water droplets off the skin.  In standard mode without a heater, it uses just 560w of electricity and works in around 13 seconds, which has a significant effect on electricity use – over the course of a year, the savings can be as much as £111.

Hand dryers can also be much more cost effective than using disposable paper towels (and better for the environment).  Using an equivalent number of paper towels annually would cost as much as £1,460, as well as contributing to the amount of waste the school will send to landfill.

How Much C02 are Hand Dryers Responsible For

Higher electricity use also means a greater contribution to overall CO2 emissions.  A conventional hand dryer will be responsible for 526 kg of CO2 from electricity generation over the course of a year, whereas over the same period, the energy efficient Mitsubishi Electric Wave u02 dryer will be responsible for just 160KG!  This, coupled with other energy efficient measures within a school can help to make big strides towards Net Zero.

While paper towels don’t require electricity, their manufacture is energy intensive.  The manufacture of an equivalent drying capacity of paper towels results in more than 3 tonnes of CO2 being released into the atmosphere, and for every tonne of paper towels manufactured, at least 17 trees need to be cut down.
