Calculate Consumption and Costs for Fan Heaters
Calculator for the energy consumption of a fan heater in a certain time and the costs for it depending on the price of electricity. A fan heater is a fairly expensive way to heat your home. However, such a device is quick, uncomplicated and inexpensive to purchase. It should only be used in exceptional cases, such as if the heating fails, if the existing heating is not sufficient in very cold weather, or if you want to get the air warm quickly and briefly.
Please indicate the power of the fan heater and the duration in days (d), hours (h) and minutes (min). The energy consumption for heating with the device is calculated. If an electricity price is specified, it will be calculated how much the heating process costs.
Example: if you operate a fan heater with 2000 watts on full power for 3.5 hours, you use 7 kilowatt hours. At a price of 35 cents per kWh, this costs 2.45 € or $.

Fan heaters get very hot, so they must be left standing freely and not covered. Ideally, they should switch off when covered or when heat builds up, but if this fails, there is a high fire hazard. Due to their high power consumption, a fan heater should always be plugged into a socket by itself, not into a multiple plug. Fan heaters should be protected from water; there are special models for bathrooms and wet rooms. Ideally, a running fan heater should never be left unattended. Fan heaters do not produce any local pollutants, although these do occur when the electricity is not supplied from renewable energy sources. Wherever they are placed, they stir up dust. If a fan heater has been unused for a long time, it should be dusted before use. Holding a vacuum cleaner in front of the grille while the device is switched off will remove the dust from the inside.
