You often leave a dehumidifier running for hours or even the whole day, so it is logical to want to know what that costs. The answer depends on the appliance's power consumption, how many hours a day it is on, and the price you pay per kWh.
How do you calculate the daily costs?
The basic formula is simple: power in watts, divided by 1,000, times the number of operating hours, times the price per kWh. For example: suppose a dehumidifier consumes an average of 200 watts and runs for eight hours a day. That is 1.6 kWh per day. At an electricity price of approximately 0.30 euros per kWh, that comes to about 0.48 euros per day, or roughly 14 euros per month with daily use.
This is a calculation example to demonstrate the principle. The actual consumption of your device and the current energy price in your energy contract may differ, so for an accurate picture, always check your own device's nameplate and your latest energy bill.
What influences the costs the most?
- The power of the device. A larger model with a higher capacity in liters per day generally also uses more power.
- How many hours a day you leave the device running. Leaving it on continuously logically costs more than running it for just a few hours a day.
- How humid the air is. With higher humidity, the device has to work harder to extract moisture, which also affects consumption.
- Your energy tariff. Electricity prices vary by supplier and contract, so the same device costs more for one person than for another.
How do you keep costs low?
Do not let the device run unnecessarily once the desired humidity level has been reached. A dehumidifier with an adjustable humidistat often switches off automatically once the desired level is reached, and back on if the humidity rises. This prevents unnecessary power consumption compared to a device that continues to run at full power.
Additionally, ensure that windows and doors remain mostly closed during use, so the device does not have to constantly process damp outside air. This way, you achieve the desired result faster, and the device runs at full power for less time per day.
Our advice
Do you want a dehumidifier that you can use consciously and without unnecessary power consumption? The Dynter AirPure DH251 is suitable for household use, and you can easily place it where you really want to combat moisture at that moment, instead of letting it run everywhere at once. By using the device in a targeted way, for example only in the room with the biggest moisture problem, you keep the annual electricity costs manageable.
Compare with other solutions
For comparison: drying laundry indoors on a drying rack without any help can significantly increase humidity and therefore indirectly lead to higher heating costs, because humid air feels harder to heat up. Using a dehumidifier in a targeted way while drying laundry is often more economical than turning up the heating to compensate for that damp feeling. So, do not just calculate the costs of the device itself, but also look at what it might save you in other areas.
