Questions.

How do I calculate heat loss from a steam header?

Add the header shell with its diameter and length, then add each branch valve as its own row. Every row is solved separately and the table totals them. Set the operating hours and the energy price once, in the settings above the table.

Are the branch valves counted with the header?

No. A shell and a valve are different shapes, so each one is a separate row. The total covers every row you add.

Does the handwheel get insulated?

No. Handwheels, the gauge and its siphon stay outside the modules, so they are not in the insulated figure.

Why is there no payback figure?

Payback appears once you enter your own installed cost. No cost rate is published here.
