Changes of Phase, Heat, Temperature | Zona Land Education

When a substance changes from one state, or phase, of matter to another we say that it has undergone a change of state, or we say that it has undergone a change of phase. For example, ice melts and becomes water; water evaporates and becomes water vapor. These changes of phase always occur with a change of heat.

Indirect water heaters — Heating Help: The Wall

Since in a 24-hour period, my boiler spends perhaps 30 minutes heating hot water (probably less), I doubt it matters much how much flow I need. My guess is that the total area of the heat exchanger is great enough, and the boiler is adequate, it does not matter which direction the heat flows to get from the boiler to the domestic part.
