Efficient Use of Washing Machines
If you have a washing machine in your kitchen or near your kitchen area, then follow this advice to save on energy.
Modern washing machines are cold-water filled, the older type having a hot and cold water supply to the machine. The old method meant that the domestic hot water entered the machine at whatever temperature you had the thermostat set at (60οC/140οF) and then cold water was added to cool it to your programmed temperature, which wasted a lot of you heat energy.
The modern washing powders and gels are designed to be used at 30οC for most washing program settings, so a cold-water filled washing machine heats the cold domestic water from around12οC to 30οC, using its electric heater.
Amount of Clothes in a Load
The washing machine is designed to operate efficiently with a full load of clothes, therefore unless absolutely necessary, clothes should be saved up and washed when a full load is gained.
Domestic Water Properties
Depending on where you live, your water supply could be hard or soft. Hard water contains minerals such as magnesium and calcium, which can scale the heaters in your washing machine. However, most modern detergents contain a water softener and if the recommended quantity of detergent is used, it will prevent the formation of limescale on your washing machine heater. There are tablets which can be used to soften the water and remove limescale which are easy to use, but not always required.
Finally, have the machine serviced once a year. Most manufacturers offer a free supply of parts and only charge for the fitting of them. There are also insurance schemes which cover the cost of spares and fitting, and the engineer normally gives the machine a service when he repairs it.
