Back in the old days nuclear power mods worked by adding a reaction, that would produce a very hot liquid, which hotness was defined in the prototype as a `default_temperature`.
However, I've recently added a liquid with `default_temperature=300` and when that one was piped to steam engine, nothing happened until I've added a boiler with the coal at which point the setup started giving minimal power. So, apparently, only the heat added by boiler counts for power production. The question is: What is the point of having the temperature fields then?

Can make two liquids both of which heat up to 100°C max, but with different min temperatures. The one with highest min temperature is the least efficient for steam engine production. Also I assume in 0.15 version steam produced will have 100°C as min temp but have a much higher max temp.

In other words, it looks pretty. You know a "boiler" only takes liquids to 100°C max. And because "steam" will not go under 100°C. And so on.

Now, it would be neat if there was some kind of heat exchanger. Then temperature differences between liquids would be significant.

Steam engines calculate their power based on the difference between the current temperature and the default temperature

Do they also account for heat_capacity or is that value only used for heating liquid up?

Well, tests show that low heat capacity liquid indeed can be used to bring engine to a full power with a single boiler.
