Generally Speaking, Federal EPA Law dictates that outdoor boilers (OWB) are for non-residential (Commercial or Business) heating only.

MOST of what is below is MY OPINION only and that of others.

It is NOT to be considered legal advice.

We have often heard that the state law takes precedence over the federal one, according to https://www.wolterskluwer.com/en/expert-insights/us-federal-vs-state-environmental-regulations-what-to-follow

If a state law gives people more rights than a federal law, the state law is legally supposed to prevail. The Constitution is a different realm altogether; due to the Supremacy Clause of the Constitution


There are two basic levels in the U.S legal system: federal law and state law. A federal law applies to the nation as a whole and to all 50 states whereas state laws are only in effect within that particular state.

State vs. EPA Enforcement. In terms of implementation and enforcement, the EPA generally will defer to a state. But because the EPA retains concurrent enforcement authority, there are specific situations where the EPA may choose to act. https://www.wolterskluwer.com/en/expert-insights/us-federal-vs-state-environmental-regulations-what-to-follow

 

Several states such as Missouri, Hawaii, and Michigan appear to have chosen to ignore the EPA's regulations altogether, and many other states appear to have no information readily found online, such as Alabama, Connecticut, Florida, Illinois, Indiana, Iowa, Louisiana, North Carolina, Ohio, Oklahoma, West Virginia and others.

At a local EPA meeting, Pennsylvania said that a coal boiler was fine (because they produce so much coal) and their regulations may have not been updated since 2011.

Tennessee appears to have no regulations for wood heaters.

Boilers are exempt from Wisconsin's wood heating regulations (NR 440.642), and the state is currently trying to pass a bill (2015 Assembly Bill 25) that will prohibit the EPA's new regulations for all wood heaters!

 

So you can see that states CAN make their own determination and laws.

It seems to me that the state is the enforcer, so it is ultimately up to YOU, the consumer to check with YOUR local County, Town or City and Department of Environmental Quality to see what regulations apply to you.

I would call from a cell phone or work phone, so they do not know where you live...

If they say no to a wood boiler, you might want to ask about COAL BOILERS because they will burn wood equally well.

If they say no again, you might want to ask about forced-air furnaces because they are NOT BOILERS! Another nice loophole.

We cannot be held responsible if any furnace can not be installed due to any laws!
