Here is how much the appliances we use every day at home can affect our bills
In any home, it is normal to hear the sound of appliances in operation. The use of these indispensable tools has a cost that depends on the frequency and duration with which we use them. The machines we have scattered around the house have a lower or higher energy consumption depending on the size and function for which they were built.
In this article we will see which appliances consume the most, from the most "energy-intensive" to the most "saving".
We have avoided talking about the frequency of use, which varies greatly from family to family. The data provided is, simply, instant absorption average, i.e. the consumption of an appliance at a given time.
Purchasing one wattmetro (they can be found everywhere for a few euros) and by placing it between the plug of the appliance and the wall socket it is possible to read the instantaneous power absorbed and above all i kWh consumed in a given period of time.
If you want to do a very quick calculation, think of a kilowatt equivale a 1000 Watt. Let's take a vacuum cleaner that absorbs 1000 Watts for every hour of use: if we divide 1000 Watts by 1 kilowatt we get 1 kilowatt hour. The kilowatt hour expresses the energy consumed in a given period of time.
In the electricity bill, consumption is expressed in kilowatt hour (o kWh if you prefer) and are the fundamental unit of measurement for knowing domestic consumption and, if necessary, for switching to another supplier.
In this regard, the most effective way to save on electricity and gas bills is to turn to a comparator like InformaticsKings Tagliacosti. With a few clicks you can compare the offers of the best suppliers on the market and get, for free, a personalized consultancy service.
Here which are the appliances that affect the electricity bill the most:
1) Induction hob
It uses neither gas pipes nor propane cylinders, but only electricity. The distrust of its use in our country derives from the fact that at start-up the coils can even absorb 3.600 Watt (therefore even higher than the classic domestic equipment of 3Kw).
During cooking, however, a single stove absorbs 2.400 (or even less) but only when used at full power. This is the case in which you intend to quickly reach a temperature (for frying, for example). If you want to cook pasta or rice, however, the absorption collapses until it is included in a range between 330 and 750 Watts.
To use an induction hob, especially if you use several cookers at the same time, it is advisable to increase the contractual energy power, to avoid sudden disconnections if you use other appliances.

2) Electric oven
Its absorption varies from 1.800 to 3.000 (and over) Watts. By keeping it switched on at 180 ° for an hour, consumption is approximately 1 kWh, in the most recent ovens even less (0,8). Consumption, in absolute terms, is therefore high, but it depends a lot on family habits. For quick use, we usually tend to use small ovens, with much lower absorption and more practical when heating or cooking small portions (and, above all, reaching the desired temperature is much faster).
3) Refrigerator
It is an indispensable appliance, present in every home, in operation 24 hours a day. For this reason one would be led to think that the annual impact on the bill is very heavy. Fortunately, in recent years the manufacturers have managed to optimize its electricity absorption, reaching the point that today an average fridge (we are talking about 200lt for the fridge department and 100lt for the freezer) is classified A + + + (according to the old energy label) e D (according to the new scale, which goes from A to G). The consumption of a modern refrigerator is around 200 kWh / year or even less.
4) Iron
This small appliance must generate a lot of heat and, consequently, consume a lot of energy. Fortunately absorption is not constant over time: it can vary from about 2.400 Watts, especially in the heating phase (when the red light comes on), to a minimum of 6/800 Watts. Usually, the average consumption is around 1100 Watts, when it is in temperature.
Absorption also depends on the power of the steam generated by the iron: for 150g / min. we are talking about 2.400 Watts, for 70g / min only 1.800.
5) Microwave oven
A microwave oven can absorb up to 2.400 Watts: let's talk, however, about when the oven is used in combination with the Grill function (generally called Crisp).
If, on the other hand, we refer to operation with microwaves only, to produce 700 Watts of power (not to be confused with energy absorption!) Approximately 1.100 Watts of absorption are needed.
The difference in consumption with a normal oven (see above) is therefore evident.
6) Phone
Unless you use a travel hairdryer (which very often absorbs about 1.200 Watts), a common hairdryer can absorb even more than 2.000 Watts. Its weight on your bill can be considerable if you use it more than half an hour a day.
7) How much does an air conditioner consume
A modern inverter air conditioner, in class A +++, it is very different from the models on the market many years ago. A consumption, at the start, which can be around 1.000 Watts or less, corresponds to a much lower absorption after a few minutes.
When fully operational, we speak of an average of 5-700 Watts. In the past, however, with a normal on-off (the compressor "started" and "stopped" cyclically) consumption was approximately double.
It is natural that it greatly affects the bill, because it is usually used for many hours a day and, especially in the southern regions, with a more temperate climate, even in winter to heat.
8) Vacuum cleaner
In the field of vacuum cleaners, great strides have also been made in recent years. Thanks to the fact that, from 1 September 2017, the European Union has The sale of vacuum cleaners that absorb more than 900 watts is prohibited (and do not exceed 80 dB of noise), on the market today there are devices that do not exceed 700 Watts. And, as a yield, they manage to aspire neither more nor less like their predecessors.
9) Water heater
The typical boiler it is nothing more than a water tank, of variable dimensions, which is heated by a resistance until it reaches a certain temperature, which is regulated by a thermostat.
To bring the water to 65/70 ° C a 50 liter water heater (the most sold, enough for the needs of two people) it generally absorbs about 1.200 Watts. Once the temperature is reached, the resistance is deactivated, until the water returns to 8/10 ° and the resistance is reactivated.
During the day, this procedure occurs several times. The absorption of 1.200 Watts is therefore not continuous, but follows a "fluctuating" trend. To avoid abnormal consumption and a drain on the bill, many insert a timer that starts the water heater only at set times.
10) TV
The televisions on the market have very different sizes and are based on equally heterogeneous types. For this reason, consumption is extremely variable. They range (are just examples) from the 25 Watts of a 24-inch LED (the most widespread technology) to the 138 Watts of a 65-inch OLED, passing through the QLEDs that have a variable consumption depending on whether they are used in HDR mode ( 113 kWh for 1000 h of operation) or standard mode (103 kWh for 1000 h of operation).
