Energy Efficiency

THE IDEAL ROOM TEMPERATURE

To ensure an optimal indoor climate during the cold months while keeping heating costs at a minimum, you should focus on two factors in particular: In addition to proper ventilation and other measures, keep an eye on the indoor humidity and room temperature.

The German Environment Agency (UBA) recommends around 68-72 degrees in indoor spaces. This can vary from room to room. For example, it can be somewhat cooler in the bedroom at around 65 degrees. Each degree counts. Every degree lower saves around six percent of heating energy. You will also ensure not to keep the indoor air temperature below 65° F, as this can increase the risk of mold growth in the home.

The reason: Air can only absorb a certain amount of water vapor and this depends largely on the temperature. The warmer the air is, the more water vapor it can retain. The cold air is only able to hold very little water and is unable to absorb additional moisture, which makes it drier than warm air. If the temperature is set too low, the air reaches its saturation point and the water vapor condenses. The result: It collects on cooler surfaces like windows and walls, which can cause the formation of mold.

OPTIMAL HUMIDITY DURING THE HEATING SEASON

Here is how you can prevent the formation of mold while keeping heating costs down: Always make sure that the humidity is in the range of 40 to 60 percent, while the temperature should remain between 68-72 degrees.

To keep track of the relative humidity levels, we recommend the use of a hygrometer (humidity meter). This provides an accurate reading of the temperature as well as the humidity at any time. As a result, you can always keep track of all units and react to changes by ventilating the room or increasing the room temperature as required. In doing so, you can protect your home from mold growth. 

DRY HEATED AIR?

In winter, indoor air humidity can easily drop below 40 percent due to dry heated air.  A Venta Humidifier is a great help here. It ensures that the humidity remains in the optimal range between 40 and 60 percent. As a result, the optimal amount of moisture is always combatting the dry heated air, which allows you to enjoy a pleasant indoor climate. Bonus: it consumes very little energy in the process.

Our devices are designed to be powerful, yet have very low power consumption with as few as 3 watts*. In comparison, about 40 watts are needed for a laptop, 100 watts for a television, and even 1,000 watts for a blow dryer.

*The minimum wattage may differ depending on the series. This information applies to our air humidifiers in the Original and Comfort Plus series (power consumption (level 1-3): 3 / 5 / 8 watts)
