Boiler Systems

Are Canadian-built boilers allowed to be used in Wisconsin?

Yes, as long as they meet the requirements of Canadian standard CSA B51. The Manufacturers Data Report (MDR) for that boiler should be reviewed.

I want to build my own boiler and use it to heat my business building and provide steam or hot water for my process. Can I build my own boiler and use it?  

No. SPS 341.42 requires that all boilers in Wisconsin be constructed to ASME Standards and registered with the National Board.

Can someone build and operate a 2-inch scale hobby boiler in Wisconsin? 

No. SPS 341.42 requires ASME construction.
