2019-5-19 · The standard pressure is 15 bar for home machines and 9 bar for professional machines! If so, why are there machines with higher pressure (16, 19, 20, 21 bar) and why do these machines cost more money? If professional coffee is made with 9 bar, then why do home machines work with 15 bar?

The 'from and at' rating is widely used as a datum by shell boiler manufacturers to give a boiler a rating which shows the amount of steam in kg/h which the boiler can create 'from and at 100°C',at atmospheric pressure. Each kilogram of steam would then have received 2 257 kJ of heat from the boiler. Get a Quote
Boiler keeps losing pressure. do you mean one moment gauge is at 1.5 bar and then suddenly it drops to near 0 or that it is a slow decrease. Some years ago I had a similar problem with a combi boiler losing pressure, and after a lot of crawling around under the floor (where there wasn't much room at
Psi : Psi is the abbreviation of pound per square inch, and is widely used in British and American. 1 psi = 6,894.76 Pascals. Bar : The bar is a unit of measurement for pressure. It is widely used in the daily life particularly in European countries, though that is a non-SI unit. 1 bar is equal to 100,000 Pascals, which is close approximately to atmospheric pressure, so it is often used to
