When choosing an air conditioning system for your home or office, one of the main criteria to evaluate is energy consumption. Viessmann air conditioners, always synonymous with efficiency and innovation, offer high performance combined with low consumption, even during prolonged use in the hottest months.
An excellent example is the Vitoclima 232-S range, available in various power outputs to suit every living requirement. These are single-split air conditioners with inverter technology and eco-friendly R32 refrigerant, designed to ensure maximum comfort with a minimal impact on your energy bill.
Here is the estimated seasonal consumption in cooling mode:
Nominal Power | Energy Class | SEER | Estimated Annual Consumption |
2.7 kW | A+++ | 9 | 105 kWh/year |
3.5 kW | A+++ | 8.5 | 144 kWh/year |
5.2 kW | A++ | 7.6 | 244 kWh/year |
These values are based on average annual usage and take seasonality into account, thanks to the SEER (Seasonal Energy Efficiency Ratio) rating for cooling and SCOP for heating. A SEER rating above 7, as seen in these models, indicates great efficiency.
How much does an air conditioner consume if it’s on for 8 hours a day?
Taking the 2.7 kW model as a reference, with a SEER of 7.8 and an average power consumption of 0.72 kW, we can estimate a consumption of about 0.36–0.45 kWh/hour, depending on the actual efficiency and the set temperature.
With 8 hours of operation per day, this leads to an indicative daily consumption of about 2.9–3.6 kWh, which is equivalent to €0.70–€0.90 per day, assuming an average energy cost of €0.25/kWh.

What does an air conditioner’s consumption depend on?
The actual consumption of a Viessmann air conditioner, like any other device, can vary based on several factors:
- The appliance’s power (expressed in kW or BTU)
- Seasonal energy efficiency, through the SEER and SCOP ratings
- The area to be cooled or heated
- Daily hours of use
- The temperature set on the remote control
- The building’s level of thermal insulation
Using an air conditioner with an energy class of A++ or higher can significantly reduce consumption compared to older models. Furthermore, the better insulated the building, the less effort the system will need to maintain a stable temperature.
How to save energy with a Viessmann air conditioner?
Buying a high-efficiency air conditioner is the first step, but to make the most of its potential, it’s important to adopt some good habits:
- Set a temperature no lower than 25°C during the summer months
- Use the dehumidifier function on cooler days
- Close doors and windows while the system is running
- Clean the air filters regularly to maintain high performance
- Use the timer to schedule on/off times according to your routine
Following this advice provides a dual benefit: constant comfort and tangible energy savings.
Viessmann Vitoclima 232-S air conditioners are an excellent choice for those who want to combine technology, comfort, and sustainability. Their annual energy consumption, ranging between 105 and 244 kWh, demonstrates how efficient they are, even in large spaces. With the right practices, you can enjoy an ideal climate all year round, without any surprises on your bill.
