Are Modern Hand Dryers More Energy Efficient

Modern hand dryers feature many innovations in their design which means they use far less energy and get better results when used – meaning better hygiene and lower electricity bills.

Choosing a More Efficient Hand Dryer

As part of the planning process when updating bathroom facilities in a building, it is useful to consider the impact that any changes will have on your net zero and energy use reduction goals. Choosing to fit more efficient, modern hand dryers could have a significant impact on electricity bills while also reducing your carbon footprint.

How Much Electricity do Modern Hand Dryers Use

The design of the Mitsubishi Electric Wave hand dryer range features multiple innovations that make them much more energy efficient than a conventional design.  The use of an ultra-efficient fan motor, coupled with the way air flows through the dryer means that much less energy is required in the hand drying process.

Jet hand dryers do not need the internal heating element that is used in evaporative dryers.  Rather than relying on slow moving warm air to gradually remove moisture, the high-speed jet of air simply blows the water off the surface of the skin.

This combination of factors – a quicker drying time and a more energy efficient design means that the Mitsubishi Electric Wave u02 hands-under dryer uses about one third of the electricity that an older design would use.  Over the course of a year, based on 100 daily uses, it will cost approximately £10 to run – or about 0.4 pence.  By comparison, a conventional hand dryer will cost approximately 1.2 pence per use.

Environmental Impact of Modern Hand Dryers

Using less electricity means that the carbon footprint is much lower than with a conventional design.  If a hand dryer is used 100 times per day over a year (approximately 25,000 times), the amount of CO2 released into the atmosphere will be 35KG.  

By comparison, a typical warm air hand dryer, using 3 times as much electricity would be responsible for 108KG of CO2 emissions.  In schools and large office buildings or factories, the annual CO2 emissions from hand dryers can easily exceed 1 tonne.

Paper towels are sometimes thought of as an environmentally friendly option as they do not require electricity when someone dries their hands, however this is not the case.  Manufacturing paper towels is highly energy intensive, and for every 100 daily uses over the course of a year, the whole process will be responsible for the emission of 624KG of CO2 – almost twenty times as much as the Mitsubishi Electric Wave i01!  In addition to this, as a hygiene product paper towels cannot be recycled – instead they must be either incinerated or sent to landfill – both bad options for the environment.
