Display Energy Certificates
Posted on | May 21, 2009 |
If you are thinking about buying a new cooker then as well as the features it has such as its capacity you should consider how efficient it is. By law many appliances have to dispay energy certificates. These tell you about how much energy your cooker uses in kWhr/yr and places the appliance in a category from A-G where A is the most efficient and G is the least efficient.
By their very nature, a lot of energy is required to heat food and cooker represent one of the most energy consuming devices in our home. An average cooker uses around 8000 W of energy. Compare this to around 1500 W for a kettle and only 400 W for a television. To put this into context, the human body releases around 100 W of energy when sitting around relaxing. However, taken against this, the time for which the oven or cooker is used is not generally more than a couple of hours a day. Whereas your fridge is on all the time.
Also taken into account is the size of the oven cavity. A larger cavity is going to have a higher energy usage but should not be rated at a higher level than a smaller oven.
What is the importance of this for the consumer? A more efficient cooker will ultimately save you money in the long run and indirectly reduce emissions of CO2 into the atmosphere, as less energy is required to be generated at the power stations or burned in gas consumption.
