14 Important Features to Consider When Buying an Espresso Machine

Choosing the right commercial espresso machine or even a home espresso machine means finding the balance between your brewing style, skill level, budget, kitchen space, and desired level of control.

From machine types and boiler systems to thermal stability and maintenance, understanding these 14 key features will help you invest wisely in a machine that fits your lifestyle. Knowing what to look for in an espresso machine includes:

1. Understanding Machine Types

Espresso machines fall into several broad categories, each suited for different users:

• Manual (Lever) machines: These require you to manually pull a lever to generate pressure, offering full control and a traditional espresso experience. They appeal to purists who value craft and skill but require practice and patience.

Some manual (lever) machines include Kees Van Der Westen Spiritello, Victoria Arduino Athena Classic Leva, and Superkop (New).

• Semi-automatic machines: Popular with home baristas ready to develop skills, these machines automate pressure with a pump but leave grinding, tamping, and steaming up to you. They provide a perfect balance of control and convenience, ideal for dialing in recipes and exploring coffee nuances.

Some semi-automatic machines include Nuova Simonelli Appia Life Compact, Faema E61 Legend 2-Group and Rancilio Classe 5 S. 

• Automatic machines: Similar to semi-automatics but with more automation, such as programmable shot volumes. They suit users who want some control without the full manual effort.

• Super-automatic machines: These handle grinding, dosing, tamping, brewing, and steaming at the touch of a button. They prioritize convenience and consistency but limit customization, making them suitable for users wanting café-style drinks fast without barista skills.

Some automatic machines include Eversys Cameo C'2M, La Cimbali S60 and Eversys Enigma E'4M. 

• Pod-based machines: Offer quick, easy espresso using pre-packaged capsules. Best for users valuing convenience over customization or technical engagement.

We, at Pro Coffee Gear, offer you an extensive selection of top semi-automatic espresso machines and accessories tailored for all skill levels. Explore our collection to build your perfect home setup.

2. Boiler Systems

The boiler configuration significantly affects temperature stability, steaming power, and workflow:

• Single boilers: Use one boiler for brewing and steaming, but they can’t perform both simultaneously. Compact and budget-friendly, these are suitable for espresso-focused drinkers or beginners. However, they often require waiting between brewing and steaming and can have less steam power.

• Heat exchangers: Single-boiler designs allow simultaneous brewing and steaming by routing brewing water through a heat exchanger. They offer faster workflow and better steaming than single boilers but come with longer heat-up times and higher energy consumption.

• Dual boilers: Features separate boilers for brewing and steaming, enabling simultaneous operation, better temperature control, and higher steaming power. These are ideal for you if you are a milk-heavy drinker or indulge in high-volume usage, but are generally costlier and consume more energy.

Pro Coffee Gear stocks a wide range of dual-boiler machines from premium brands, perfect for those of you who want professional-level performance.

• Instant-heat systems (Thermoblock, Thermocoil, Thermojet): These systems heat only the water needed for each brew or steam cycle, making them fast and energy-efficient. Most are ready to brew in under two minutes. Some newer machines can now switch quickly between brewing and steaming.

3. Thermal Stability and PID Temperature Control

Consistent temperature during extraction is vital for flavor balance and repeatability. PID controllers electronically manage water temperature with precision and are now common across many machines, even budget models. 

Some offer adjustable temperature settings, while others maintain fixed levels. A PID system is essential for avoiding temperature fluctuations between shots, especially on single-boiler and heat-exchanger machines.

Find espresso machines equipped with PID controllers and precise temperature control at Pro Coffee Gear, ensuring your shots are consistently delicious.

4. Pressure and Pump Types

Optimal espresso extraction requires about 9 bars of pressure. Most machines use vibratory pumps, compact and affordable but louder and shorter-lived or rotary pumps found in prosumer and commercial models and which are quieter and more durable. Beware of exaggerated BAR claims, as internal valves regulate pressure to the correct level.

A three-way solenoid valve for pressure relief is important to avoid messy sprays when removing the portafilter after a shot and is typically found in machines priced above $500.

5. Group Head and Portafilter Size

The group head design impacts thermal stability and maintenance ease:

• E61: Classic, robust, and user-friendly with wide aftermarket support.

• Saturated: Integrated with the boiler for superior temperature control, common in commercial machines.

• Electronically heated: Provides precise, adjustable temperature control during extraction, found in high-end models.

Portafilter sizes usually range from 49mm to 58mm, with 58mm being the commercial standard offering the broadest accessory compatibility and support for larger coffee doses, especially important for lighter roasts.

Visit Pro Coffee Gear, as we offer portafilters and accessories compatible with a variety of group heads and sizes to customize your setup.

6. Water System: Reservoir vs. Plumbed and Filtration

Most home machines use reservoirs, but higher-end setups may offer direct plumbing for convenience and a consistent water supply. Built-in water filtration systems improve espresso flavor and machine longevity by reducing mineral buildup. Using filtered or spring water is highly recommended in general, regardless of your chosen setup.

Explore our selection of water filtration solutions to optimize your espresso water quality.

7. Milk Frothing and Steam Wand Quality

For milk-based drinks, steam wand power and design matter. Dual boilers or heat exchanger machines provide better steaming power and allow simultaneous brewing and steaming. Some instant-heat models offer fast temperature switching but vary in frothing performance. 

TIP - Features like adjustable steam tips can improve milk texture for latte art.

8. Programmability and Convenience Features

Modern espresso machines often include programmable shot volumes (volumetric control), pre-infusion settings to gently saturate coffee grounds before full pressure, and shot timers. These features enhance consistency and make brewing easier for beginners and even busy users.

9. Space and Workflow Considerations

Assess your kitchen space for machine footprint and height, including clearance for water tank removal and accessory placement. Workflow factors like button layout, ease of access to controls, and drip tray size affect your daily experience. A well-designed workflow can turn coffee-making into an enjoyable ritual rather than a chore.

10. Build Quality and Materials

Higher-end machines use durable materials like stainless steel, brass, and copper internally, enhancing heat retention and longevity. Exteriors vary in style and finish; choose one that fits your aesthetic, but also consider ease of cleaning and durability.

11. Maintenance and Repairability

Regular maintenance, using filtered water, descaling, cleaning group heads, purging steam wands, and replacing gaskets is crucial for your machine’s health, no matter which one you choose. 

Espresso machines that are easy to service with available parts and community support offer better long-term value. Consider the "right to repair" and warranty support before finalizing your purchase.

We provide you a detailed product support and genuine replacement parts to keep your machine running smoothly for years.

12. Energy Consumption and Environmental Impact

Espresso machines vary widely in energy use. Traditional dual-boiler machines can consume over 1,000 kWh/year, while modern instant-heat systems may use less than 200 kWh/year. Choosing energy-efficient models reduces environmental footprint and electricity costs. Choosing high-end models is a preferable option if you run a business.

13. Grinder and Scale: Essential Companions

Freshly ground coffee is critical for great espresso. Invest in a quality standalone espresso grinder tuned for consistent particle size. A reliable scale ensures precise measurement of coffee dose and shot yield, which is key for repeatable results.

Pair your espresso machine with grinders and scales available at Pro Coffee Gear, ensuring optimal preparation and consistency.
