What is Boiler Capacity?

The volume of water a traditional boiler can hold and heat, measured in milliliters.

Measured in ml

What is Boiler Capacity?

Boiler capacity applies to machines with traditional boilers (not thermoblocks) and specifies the amount of water stored and heated within. A larger boiler capacity can offer more stable temperatures and greater steam power for milk frothing compared to smaller boilers or thermoblock systems, though it may have a longer heat-up time.

Why does boiler capacity matter?

A larger boiler capacity contributes to more stable brewing temperatures and sustained steam production, which is crucial for making consistent espresso shots and achieving high-quality milk froth for lattes and cappuccinos.

What is a good boiler capacity value?

Larger boiler capacities (e.g., 250ml+ for brew, 1L+ for steam) generally indicate better temperature stability and sustained steam production.

How is boiler capacity measured?

Boiler Capacity is measured in ml.
