Frequently Asked Questions

What is a boiler valve?

A boiler valve can be opened or closed to change the flow of boiler water. When open, boiler water will flow to the designated set of piping, and when closed, either the boiler water stops flowing, or at least flows in different directions. A universal law of hydronics is that water will always flow in the path of least resistance.

What is a boiler drain valve used for?

A boiler drain valve can be opened to allow boiler water to flush out completely, or at least partially to keep the boiler clean.
