DISHWASHING MACHINES VERSES

HAND WASHINGGemma Jones

Introduction I am going to look at the positive and

negative effects between manual hand washing dishes

and dishwashing machines through;

Cost Energy Time

Water usage On average a person will use 123 gallons

of water a day. This is through,

Showering Brushing our teeth Shaving Washing dishes And flushing the toilet.

Hot Water dishwashing Machines

Hot water dishwashers are said to be more effective than hand washing because:

They only use a limited amount of water There is no chance of your dishes breaking The dish water is heated inside the dish washer It only heats the amount of water needed It will Save you time, just load and set timer

then you can leave it till it finishes The dishwasher can control how much water it

uses.

Hot water dishwashing Machines

The machine only uses 9-10 gallons of water. One- sixth of the water we use hand washing dishes

It is a lot quicker than hand washing More hygienic than hand washing

Steam Dishwashing Machines

However Steam dishwashing machines are said to be more efficient than hot water dishwashing machines. This is because:

Washing dishes with steam helps the machine consume less energy, therefore saving you money on you energy bills

Huge amounts of steam can be produced from little amounts of water

Steam is better at cleaning than hot water.

Cost We use around £2 billion a year on

electricity by using dishwashers, tumble dryers and washing machines

Dishwashers do around 246 cycles per year.

This produces 8 million tonnes of co2 each year which is the equivalent of 2.5 million cars.

Hand washing Dishes There are not many benefits to hand

washing. Some facts are:

On average a person will spend around 50 minutes a day on hand washing dishes, making it time consuming.

you use around 20 gallons of water Not very Hygienic

Solution

Replacing old dishwashing machines with new Energy saving recommended ones

This will save around 20% less energy Will save you around £12 per year on

energy bills and around 48kg of co2. Wait for a full load or use economy cycle

(if there is one)

Conclusion Using an energy saving dishwashing machine will save

you around 230 hours a year compared to when you wash dishes manually.

energy saving dishwashing machines will save you around £12 a month on energy bills

On average a dishwashing machine saves around 11 gallons of water less than hand washing dishes

And will also save around 48kg of co2 that enters our economic system each year using an energy saving dishwasher.

Taking all factors into consideration it is clear

that dishwashing machines are better all round than manually hand washing dishes.
