Weller Advisors tracks commercial boilers and pressure vessels at the unit level — age, class, manufacturer, owner, and certificate dates — kept current for every county we cover. Service teams use it to reach the building before the renewal is spoken for.

Priority-scored county lists: aging units, expiring certificates, internals due. Your reps see which buildings matter this quarter and call them first.
Every internal inspection opens a boiler in front of its owner. We map the accounts entering that window, and the new installations about to specify their first treatment program.
The aging installed base by maker and territory — which defunct-brand units are still running, and where replacement demand will surface next.
Real records, shown in the working format. Identification is blurred until you request your county.
Write with your territory and we'll send a sample sheet from the live dataset — actual sites and certificate dates. If it's useful, we'll talk coverage. You'll hear back within a business day.
