Recent U.S. Department of Energy (DOE) efficiency declarations were overturned, once again allowing the production and sale of Burnham Commercial boiler models with inputs of 300 MBH and above, specifically the V9A, V11H and MPC models.

Earlier in the year, a DOE ruling temporarily affected some Burnham Commercial boiler models, though they are now reversed.  While the Burnham Commercial Series 8HE product line was updated during the past year, they now have the 805HE through 810HE (239-505 MBH) sizes available for sale.
