There have been many changes in the UKs interest in coffee in the last 10 - 15 years. The need for real espresso based coffees has increased dramatically. Instant coffee out a tin or at best "Pour and Serve" filter coffee machines were the main way of providing coffee during the past thirty years. I can speak from past experiences when selling coffee machines that prepare "real bean" espresso based coffees to businesses in the food and drink sector. These days those types of business wouldnt consider anything less than a traditional Espresso machine or Bean to Cup machine. Back then the British public was really only used to "instant" type coffee and Espresso was something foreign. Businesses didnt see the need to go "foreign."
One that is not as popular as all the others is the vacuum machine. They come in many shapes and sizes yet they are more alike than they are different. This system heats the water in the lower chamber creating a water vapor. This increases the pressure in the lower chamber and forces the water upward into the upper chamber that you add just before the water begins to rise. Brew for about 1.5 minutes then remove from heat the gases in the lower chamber cool and draws the brewed coffee downward via suction caused by a partial vacuum that ensures accurate extraction of oils and caffeine for a cleaner unit without the bitter taste.
If you work in a small office a machine with a small carafe is sufficient. However you work in a very large office a machine that can fill a large coffee urn might be what is needed. Another feature that would be useful in this type of environment is a machine with a "time to clean" indicator coupled with a self clean feature. Often calcium buildup can occur in these machines and an indicator of when the machine needs to be cleaned is important. In a shared environment it is very likely that responsibilities like cleaning the coffee machine can be ignored due to the phenomenon known as the tragedy of the commons. By having a machine with simplified cleaning measures like an auto-clean you can avoid the pitfall of nobody taking responsibility to clean.
Another advantage of this type of brewer is that everyone can brew the kind of coffee that they like. If someone in the house is a bold coffee drinker and another likes a milder type they are not stuck drinking something that wasnt their choice. I have family gatherings at my home regularly and coffee after dinner is commonplace. Everyone is very pleased with the fact that they can choose whatever they would like for their coffee.
