Commonwealth Woodstove Change-Out - FAQ


How do I determine whether my current stove is EPA-certified?

  • All woodstoves legally manufactured for sale in the United States on or after July 1, 1988 were required to achieve EPA certification, and are considered to be EPA certified for purposes of this program. Stoves manufactured after this deadline are marked with a permanent EPA certification label or tag on the back of the stove. Stoves certified by the 1988 New Source Performance Standard are also listed here. If you are not sure if your current stove is EPA-certified, first check the back of the stove for an EPA tag. If you are still not sure, then search for your stove in the above mentioned list.

What are the requirements for EPA-certified stoves?

  • Under the 1988 New Source Performance Standards, all stoves manufactured for sale in the United States after 1990 must emit 7.5 g/hr or less of particulate matter. Although new requirements released by the EPA in 2015 further decreased this threshold to 4.5 g/hr, MassCEC recognizes all stoves certified under either the 1988 or 2015 NSPS as EPA certified for the purposes of determining which stoves can be replaced under this Program.

How much will my rebate be?

  • Standard rebates range from $500 to $1,750 per change-out, and low-income rebates range from $1,500 to $3,000, based on stove specifications. See Table 1 in the program manual for details.

How do different stove types compare in terms of price?

  • Typically, the stoves with the lowest emissions and most automated features are the most expensive. However, stoves should be evaluated based on the homeowner’s needs. Fully automotive woodstoves are, on average, the most expensive woodstoves, but are the cleanest burning when installed. Pellet stoves, which generally have lower emissions than traditional woodstoves, tend to be moderately more expensive than traditional wood stoves, in part because most have automated components and other high-end features. Catalytic stoves are moderately more expensive than non-catalytic stoves. When comparing non-catalytic stoves to one another, models that emit more grams per hour of particulate matter ironically are often more expensive. In some cases they are simply less effective at eliminating particulate, while in other cases they simply have the capacity to burn more wood and provide more heat on an hourly basis. The Commonwealth Woodstove Change-Out Program's higher rebate levels for low-emitting stoves aim to compensate homeowners for buying cleaner-burning models.

​What if I don't have an old stove to trade in?

  • While a non-EPA-certified stove is require to qualify for a Commonwealth Woodstove Change-Out Program rebate, homeowners who do not have stoves still may be eligible for rebates for other clean heating and cooling technologies.

​What types of stoves are eligible to be changed out? What stoves are eligible to be installed?

  • Old, non-EPA certified wood stoves and inserts are eligible to be changed out. Old coal, gas, and pellet stoves are not eligible for this change-out program. Homeowners can replace these old wood stoves only with wood and pellet stoves and inserts that are on our Qualified Equipment List .
