PostHeaderIcon The voltage at my summer cottage “jumps”. Does it affect the heaters somehow?

The permissible variation of the voltage in the network for infrared heaters is 10%. With more significant deviations in the smaller side, infrared heater will naturally emit 10% less heat. If the voltage is too low, the lamellae of the IR heater cannot radiate power required, which leads to an increase in the time of heating the room.
