The energy-intensive coffee machines have already been called off. Pack the old energy guzzler and send it out of the café. In its place, install a shiny darling that will attract the attention and admiration of customers, will match the overall interior of the café and will save you over €1,000 a year! This is what new professional coffee machines with modern energy-saving technologies can do.
Summary for the impatient:
- New generation professional coffee machines save over €1,000 per year on energy
- More modern models use better boiler insulation, PID temperature control and Eco modes
- Return on investment in a more expensive coffee machine: 2.5-4 years just due to energy savings
- Saving CO2 emissions by up to 2 tons per year – a marketing advantage for organic cafes
- Modern coffee machines provide higher quality coffee and increase barista productivity
How much energy does a professional coffee machine "eat"?
Professional coffee machines They work on the principle of heating water to the ideal extraction temperature (92-96 °C) and creating the pressure needed for espresso extraction. The main energy-intensive components are boilers that consume up to 70% of total energy coffee maker. The rest of the energy is then taken by the rotary pump and control electronics .
A typical two-lever professional coffee maker can have a power consumption of 3000-6000 W. In standby mode (keeping warm), it consumes around 400-800 W, depending on the insulation and technology.
Energy consumption of old vs. new coffee machine
Let's compare the consumption figures side by side. As an example of how manufacturers' approach to coffee machine energy efficiency is changing, I have selected three of the most widely used 2-lever professional coffee machines. of the Nuova Simonelli brand .
Specifically, we will compare consumption "second" series of Appia coffee machines vs. the current Appia Life and the third coffee machine in the comparison will be the new Aurelia , which is among the newly modernized models of coffee machines from this manufacturer.
Nuova Simonelli Appia II
The Nuova Simonelli Appia II, although a respected coffee machine, belongs to the older generation with several energy disadvantages:
- standard boiler insulation
- thermostatic temperature control
- limited power saving modes
- power consumption approx. 4300 W
Nuova Simonelli Appia Life
Appia Life presents an upgraded version that brings significant improvements:
- boiler insulation with advanced materials (hygroscopic fibers Drytex Thermical)
- more sophisticated electronic temperature control
- available energy saving modes (Eco mode)
- Power consumption approx. 3350 W
Total approximately 20-27% energy savings compared to the Appia II model
Nuova Simonelli Aurelia
The new Aurelia represents the pinnacle of technological advancement in energy saving:
- revolutionary Soft Infusion System for optimal extraction
- the most advanced PID temperature control with an accuracy of one tenth of a degree
- Smart Boiler technology with adaptive learning for performance optimization
- patented T3 technology with three independent thermal controllers
- Power Saving Plus mode with advanced adaptive power management logic
power consumption approx. 4700 W (higher than Appia II, but significantly more efficient thanks to modern technologies)
Saving up to 50-55% energy compared to the Appia II model

How do new coffee machines save energy?
- PID temperature control
- Multi-level boiler insulation
- Eco modes and intelligent power management
Economic Analysis: Energy Cost Comparison
We will perform a financial analysis of all three models when operating 12 hours a day, 30 days a month with a price of €0.20/kWh:
Nuova Simonelli Appia II
- Average daily consumption: 22 kWh
- Monthly consumption: 660 kWh
- Annual consumption: 7920 kWh
- Annual energy costs: €1,910
Nuova Simonelli Appia Life
- Average daily consumption: 16 kWh (savings 27%)
- Monthly consumption: 480 kWh
- Annual consumption: 5760 kWh
- Annual energy costs: €1,390
- Annual savings compared to Appia II: €520
Nuova Simonelli Aurelia
- Average daily consumption: 10 kWh (savings 54%)
- Monthly consumption: 300 kWh
- Annual consumption: 3600 kWh
- Annual energy costs: €870
- Annual savings compared to Appia II: €1042
With indicative price differences in input costs:
- Appia II: approximately €4,420
- Appia Life: approximately €6,430
- Aurelia Wave: approximately €8,440
The return on investment for the Aurelia model compared to the Appia II is approximately 4 years from energy savings alone. If we include other benefits such as better coffee quality, higher barista productivity and lower service costs, the return is shortened to approximately 2.5 years.
Environmental aspect and marketing advantage
Saving 40,320 kWh per year (the difference between Appia II and Aurelia) represents a reduction in CO2 emissions of approximately 2 tons per year. For cafes that focus on ecological operation, this fact represents a significant competitive advantage.
ℹ️ To turn off or not to turn off the coffee maker: how about saving energy at night?
Switching the coffee maker on and off daily can have a negative effect on the wear and tear of the components in the coffee maker. The other side of the coin is the need to constantly reheat the coffee maker if it has not been used for several hours. In older coffee makers, nighttime consumption was higher than the energy requirement when heating the coffee maker from a cold state. With a modern coffee maker, however, night mode is the same or lower in energy than starting the coffee maker in the morning. Switching it off only makes sense when there is a break in operation of several days.
***
For busy cafes, the difference in energy consumption between the oldest and newest models can be saving almost €1045 per year . Which makes economic sense in the long term. Despite the higher initial costs, it is then Investing in a new, more environmentally friendly coffee machine is also an economic win for coffee shop owners . In addition to direct financial savings, more modern coffee machines also bring higher coffee quality and productivity.
