Heat wave and climbing invoice: these connected devices in your home aggravate heat

Closing the shutters and ventilating early in the morning are simple gestures to refresh accommodation. Disconnecting unused electrical devices is also recommended: even in standby, they consume energy – a phenomenon called “Phantom Power”.

Reduce heat production

According to ADEME, the devices left in standby represent an average of 11 % of the annual energy consumption of a home.

TVs, Internet boxes, office pc or printers continue to heat, even in standby mode. Except that each additional heat source in a housing helps increase the room temperature. In the heat wave, disconnecting these devices if you do not use them allows you to limit the passive thermal elevation of the accommodation.

Small household appliances are to be watched closely: toaster, coffee makers, kettles or microwaves, even when they are not used. Ditto for the washing machine, dryer and dishwasher. Their operation generates latent heat, it is better to avoid using them during the hottest hours. It is recommended to program them at night or early in the morning.

Same thing for extra radiators or electric heaters. Even inactive in summer, these devices represent a risk of accidental overheating in the event of malfunction or tension on the network, especially in old or poorly ventilated housing.

Portable fans and air conditioners are very useful during the heat wave but continuous operation can cause heat accumulation at the level of engines and excessive consumption. Especially if these devices are not maintained. Remember to take breaks and maintain filters.

Avoid letting your phone load in the void: in addition to consuming electricity, you emit heat. Multiplying all these gestures, at the scale of a home, has an impact on the interior temperature and the electricity bill. Finally, remember to replace the old incandescent or halogen bulbs with LEDs, more economical and colder.

Faced with ever more frequent scorching episodes, so remember to unplug non -essential devices, program hollow hours and monitor unnecessary heat sources.
