Energy label televisionsand consumption: how much a TV consumes and how to read its energy label. How to calculate TV consumption for each hour of operation and on an annual basis.
In addition to consumption and the energy class of the TV, you may be interested in the page dedicated toenergy class of the refrigerator.
Energy class tv
Theenergy classes of televisionshave undergone several changes in recent years.
- In 2011, the TV energy consumption classes ranged from A to G.
- In 2014, the TV energy consumption classes ranged from A + to F.
- The energy classes of the TVs recognized since 1 January 2017, range from A ++ to E.
- From 1 January 2020, the tv energy classes will go from A +++ to D.
It is clear that, to date, itelevisionsthat consume less are those of class A ++ even if, in fact, the most common ones are in class A +.
Television energy label
Fromenergy labelof aTVwe can obtain detailed information about the annual consumption of the appliance. In particular, on thetv energy label we will have info about:
- Manufacturer name and model number
- The energy class of the appliance
- Consumption, absorbed power expressed in watts, when the television is on (consumption per hour).
- Consumption expressed in kilowatts with an estimate on an annual basis.
- Screen diagonal size expressed in both cm and inches.
On the most virtuous TVs, the consumption of the TV in stand by is also indicated. In this case, a switch icon is visible on the label which indicates that the device in stand by consumes less than 0.01 Watt.
How much does a TV consume
THEconsumptionof a TV should be estimated based on the actual use you make of the device.
L'tv energy label reports the annual consumption ... but how do they calculate this consumption? On what basis thetv energy label expresses that particular value?
The value of consumption you read ontv energy labelrefers to daily use of the device for 4 hours. So, 4 hours a day multiplied by 365 days a year.
Take for example my 55-inch Samsung TV, its energy class is A + and it has an annual consumption of 118 kWh. That means for 1460 hours of use, minetelevisionit absorbs 1,460 kWh, which also means that for every hour of use the TV consumes about 81 watts.
The consumption per hour is indicated on the energy label and is added to a certain amount of energy ofstarterfor switching on the appliance.
On average, the electrical power absorbed by theTVhas an annual cost of about 9 euros if we talk aboutconsumption of a class A + TV. If the TV in question is in class A ++, consumption drops to 6 euros per year. The consumption of class A + and A ++ TVs are very advantageous if you think that with the old onestelevisionsof class G managed to consume more than 50 euros of electricity per year.
Measure the consumption of a TV
To find out how much a television consumes, a lot of information can be given by the energy label, but nothing is better than a field test. There are some very useful consumption meters on the market. This is a simple adapter to which you are going to plug the TV before stick itinto the wall socket.
A decent consumption meter can be bought on Amazon at a price of 19.06 euros with shipping costs included in the price.
The device just indicated is very economical but does not allow you to accurately record the absorption of electrical appliances with low energy consumption. If you want to measure the consumption of thetelevision on stand byyou need a more accurate meter. Among the various models on the market, the one with the best value for money can be bought with 29.99 euros and free shipping costs. For all product information:RCE PM600 precision meter, the meter is able to measure the absorption of even tenths of a watt (lamps, TV in stand by, decoder, microwave in stand by ...).
