Corrections are the most useful thing you can send. If a capacity, a pipe volume, or a Cv on this site does not match the source it cites, we want to know.
Reporting a bad number
Include, if you can:
- which calculator and which field
- the inputs you used and the result you got
- the published document and page that says otherwise — a PDF link or a manufacturer catalog citation
Measured vent capacities are especially welcome. Several Gorton models still have no published CFM rating, and this site marks those as gaps rather than guessing.

What we cannot help with
We cannot design your system, diagnose a specific building remotely, or size a boiler. Those need a survey and a load calculation by someone licensed in your jurisdiction. See About for what these tools are scoped to do.
