Commercial Double Boiler Espresso Machines

Below you will find some of the best commercial double boiler espresso machines on the market. We are very selective in double boiler models we carry.[expander_maker more=”Read more” less=”Read less”]

—Comparison to Heat Exchange Espresso Machines—

Espresso quality in the cup

Double Boiler Espresso Machines have superior control over Heat Exchangers in the temperature control of the boiler water. This better temperature control allows you to change the boiler water temperature to match better with your current coffee blend. The superior temperature control offers a better extraction in the quality found in the cup. Therefore, 1st-line ‘considers’ the PID double boiler machine is a better choice for espresso-only consumption.

There have been arguments that the coffee boiler size on a double boiler can determine espresso quality in the cup. For example, some argue that a smaller boiler will have faster turnover of the water. As a result, this fresh water makes superior espresso. At first, we were a believer in this camp before we carried double boilers. We no longer believe this theoretical model holds true. Our reasoning is that if the smaller coffee boiler theory held true, then a heat exchanger machine with a much smaller capacity would make extract superior espresso over a double boiler machine.

Steaming capacity

From our observations, a heat exchanger model is a more powerful steamer than a double boiler. If frothing or steaming milk, a heat exchanger is superior as they seem to have more steaming power and more steaming capacity than a double boiler. The reasons are:

1. higher steaming performance of a heat exchanger will allow quicker turnover in producing cappuccinos and lattes,
2. espresso quality is “not important” since milk will dilute the espresso and the quality of the cup will be insignificant.

Warm up time

The Vibiemme heat exchanger model takes about 20-30 minutes to warm up. The double boiler version takes about 30-45 minutes to warm up both boilers. You can place Vibiemme espresso machines on a timer. However, you MUST plug the timer in the wall outlet first. Then a surge suppressor (1080 joules or higher), and then either model into the surge suppressor. On the La Spaziale double boiler machines, only the Version 2 can accept a specialized Spaziale timer. The Version 1 units can not be on a timer at all.

Energy Savings

The double boiler version allows the user to independently turn on/off the coffee boiler or steam boiler. As a result, if the user only operates the coffee boiler, electrical usage is only 600 watts for the coffee boiler heating element. In contrast, a heat exchanger has one on/off switch for the entire machine.
