Title: EPA qualified boilers
Post by: dirtdigger on September 26, 2014, 04:17:41 AM
I've been told a lot of information but I just heard a new one yesterday, is it true that the EPA certification only applies to btu output of 300,000 and below and nothing above that rating is even regulated or will be?

Can anyone shed any light on the issue of a pressure vessel being regulated differently than an open air system, I guess the basic question I have is this, are both types tested the same as far as emissions and how the boiler works, only that the pressurized system has to meet the criteria of a pressure vessel.

Some states do exempt boilers over 300,000 BTU's, check with your local code enforcement, pressure vessels do go through the same emissions standards and also are tested more stringently for pressure.
