It brings the boiler water too close to the steam outlet and drives water up into the system. Before you know it, you have more problems than you bargained for. Save yourself a headache and have the customer cover the tankless coil by hand once a year. The gauge glass is your way of knowing where the water is in the boiler.

Can you compress a liquid (water)?

Can you compress a liquid (water)? Asked by: Guy Matthews Answer The answer is yes, You can compress water, or almost any material.However, it requires a great deal of pressure to accomplish a little compression.For that reason, liquids and solids are sometimes referred to as being incompressible.

The results showed that the boiler's pinch point necessitated trade-offs between maintaining adequate boiling pressure while achieving acceptable cooling of the EGR and superheating of the water. The expander used in the system had a geometric compression ratio of 21 together with a steam outlet timing that caused high re-compression.

Q amp; A: water temperatures | Department of Physics

It is not true that water can only get up to 212 degrees and as cold as 32 degrees. After water changes from a liquid to a gas (at 212 degrees Fahrenheit) it can actually heat up much hotter than that. In the gas form, water molecules are spread out and have a lot of room to move and get much hotter than the other two phases (liquid and ice).
