Despite claims of "devastating" impact, wood stove industry positioned to meet new emission standards

With the Step 2 deadline for wood and pellet stoves just a year away, most stove manufacturers say they are ready or will be soon. Many retailers also say they are ready, while others prepare to deeply discount stoves that can't be sold after May 2020. Gone are the days when industry was trying to convince Congress and the Administration that EPA's new stove regulations would have a "devastating" impact. Such claims are common in Washington, as groups try to rally their base, but it can also lead to a diminished credibility for an industry association if the hyperbole goes too far.
From the start, it was clear that the boiler and furnace manufacturers needed relief far more than stove companies and retailers.  Heads of outdoor boiler companies and indoor wood boilers that cost less than the average wood stove were leaders of a campaign to get Congress to give all classes of heaters a three-year delay in meeting the new standards.  At the same time, the industry association Hearth, Patio & Barbecue Association (HPBA) was challenging many of these standards in court, meaning a three-year delay could be permanent for some classes of heaters, if courts agreed with HPBA.  But it was never clear that stoves needed any delay and industry effort would have stalled innovation and efficiency improvements and put tens of thousands of families at higher risk of more wood smoke exposure.  The fallback position was that industry needed a two-year sell year, allowing manufacturers to sell Step 1 product during the fall and spring of 2019/2020, and retailers to sell Step 1 product until May 2022.  

At first, it appeared that the EPA under the current Administration was open to providing a two year  sell-through for stoves, but they have only issued a Notice of Proposed Rulemaking (NPRM) for boilers and furnaces, not for stoves.  Theoretically, the EPA could still issue a Notice of Proposed Rulemaking for a sell through for stoves but at this point it may be too late to provide any meaningful relief.

Many states pushed back strongly against watering down the NSPS and no state filed comments backing the Trump Administration's proposals.  States also began preparing their own plans in the event the EPA does change NSPS timelines, which could create a patchwork of regulations and more antagonistic relationships with a renewable energy industry.


If some manufacturers were not taking the 2020 deadline sufficiently seriously from 2016 - 2018, they are all likely to be doing so now.  Instead of focusing on government relief, HPBA's outreach to industry stakeholders is taking an a more urgent tone that everyone needs to focus on heeding the May 2020 deadline. However, almost all manufacturers were already focused on May 2020 for their own financial health and to assure their retailers that they are a reliable future partner.  And, many manufacturers and virtually all retailers already are well-diversified with gas fireplaces and stoves which often outsell their wood and pellet appliances.

The list of stove manufacturers who are ready for 2020, almost are or “well-positioned” to be 2020 ready grows by the week. As of May 1, they include:  APR Industries, Blaze King, Even Temp, ExtraFlame, Foyers, Heat Tech, Hearthstone, Innovative Hearth Products, Jotul, Kuma, Laminoux, MF Fire, Napoleon, Pacific Energy, Rais, Regency, Roby, RSF Fireplaces, SBI, Stuv, Supreme, Thelin, Travis and Woodstock Soapstone.  Hearth & Home Technologies, by far the largest manufacturer, says a majority of its stoves will be 2020 certified this year.

The 2020 deadline will undoubtedly be tough for much of the industry, but it remains to be seen if it’s tougher than lean shipment years such as 2007 and 2012.  Overall, the threat to industry does not appear to be as serious as industry claimed even a year ago.  The 2020 deadline is also bringing about benefits. some foreseen and others not. Some retailers still have stocks of Step 1 stoves and there is likely to be some heavily discounted stoves in the final year leading up to the deadline.  Retailers are still ordering some Step 1 stoves, but in much smaller quantities.  Many retailers are only buying Step 2 stoves but may face still competition from fire sales of Step 1 stoves by competitors.  Sending Step 1 stoves to Canada could have been a good outlet, but the more populous Canadian provinces have either adopted the 2020 deadline or are in the process of doing so. Other foreign countries are still a good option.  Most big box stores have the buying power to protect themselves by requiring manufacturers to buy back unsold inventory, influence that specialty hearth retailers don't have. 


Over the last six months, HPBA has developed more clear and insistent messaging for retailers and is using social media more to get the message across.  A facebook post outlined 5 things retailers need to know to survive the NSPS. Included is also a fear that in the race to meet the 2 gram an hour standard, some manufacturers may be putting out stoves that haven't been sufficiently beta-tested and simply won't work well in the real world.  This could jeopardize retailers who unknowingly carry those stoves.  HBPA urged retailers to test the stoves themselves, before selling them to customers, a tall order for retailers over the summer season.  The message for consumers is that the next twelve months will be a buyers’ market with unprecedented sales and discounts of Step 1 products

For the most part, the hyperbole from industry that consumers would be priced out of new stoves and there would be very little variety of product on floors, is not materializing.  Some manufacturers that were well known for disparaging catalytic stoves are now embracing them, swelling the ranks of "hybrid" stoves that only mention the catalyst in the fine-print. Presumably, this new crop of hybrids learned the tough lessons of the 80s and 90s, and their catalyst are well protected from flame impingement.


The 2020 deadline is also providing industry a gradual transition to cordwood testing, as some manufacturers opt to test with it.  Some groups idealistically hoped for a far quicker transition to cordwood.  Stoves tested with cordwood can emit up to 2.5 grams an hour, although many of them are coming in under 2 grams.  Despite messaging in advertisements from HPBA that it "shares the same goals as regulators," the 2.5 gram an hour standard for cordwood is one of the many emission standards that HPBA is challenging in federal court.  The many delays to the lawsuit may make it tougher for HPBA if enough stove models come in under 2.5 grams an hour using the broadly applicable alternative ASTM cordwood test method.

Many stakeholders are already looking past the 2020 deadlines toward the next NSPS, which by law should be scheduled in 2023.  Whenever the 2015 NSPS is superseded, there is likely to be intense controversies over certification protocols for cordwood testing and a timeline for all stoves to be tested with cordwood.  Key northeastern states believe the consensus driven ASTM Method is deeply flawed and are working behind the scenes on new test methods.


Unlike the 1988 wood heater NSPS that decimated the ranks of small stove manufacturers, the 2015 NSPS does not appear to be forcing manufacturers out of business. The 1988 regulations drastically improved the functioning, safety, cleanliness and efficiency of stoves while also driving up prices of those that were not claimed to be exempt.  The question remains whether the 2015 NSPS will significantly improve the functionality of stoves as they become cleaner and more efficient in the lab. Pellet stoves may the winners as their lab numbers should hold up in homes of consumers, a significant benefit that is rarely acknowledged by most in industry.  We can all agree that there will be both intended and unintended consequences which will take years to unfold.  Stay tuned.

March 11, 2020 update: The EPA finalized amendments to the 2015 NSPS and did not provide a retailer sell-through.  They did remove pellet fuel minimum requirements but retained the list of prohibited fuels in the 2015 NSPS.

New EPA Stove Regulations Begin Cleaner Chapter for Wood Heating

Statement by the Alliance for Green Heat on the Wood Heater NSPS

Key EPA architects of this NSPS include
Greg Green, left, and Gil Wood,  right  and
Amanda Simcox. Gil retired on February 3. 
Overall, the EPA did a good job and released a fair rule that includes many compromises between industry and air quality agencies.  We think these rules are good for consumers and will not drive prices up substantially for most product categories, but will result in cleaner and more efficient appliances that will ultimately save consumers time and money. This is our initial reaction to the rule, which we will be followed by a more thorough analysis.

High performance stoves: The EPA took some key steps to address the lack of recognition for high performing appliances. Notably, stoves that test with cordwood in the next 5 years can use a special EPA label that will alert consumers that the device is designed and tested for use like the consumer will use it. This shift is possibly as important than just lowering emission standards for wood stoves. Along these lines, the EPA is also allowing stoves that already meet the 2020 standards, to use a special label so consumers can more easily recognize these higher performing stoves. We are, however, very disappointed that the EPA removed the long-standing requirement that all stoves have a consumer hang-tag that helps consumers better appreciate the basic differences between all stoves on the showroom floor.

Boiler testing: Another positive step forward is EPA’s recognition of the European test method EN303-5 to certify European style indoor pellet boilers that have been accepted by Renewable Heat New York (RHNY). Also boilers certified by the New York State Department of Environmental Conservation (NYSDEC) will be automatically deemed EPA certified. This is another step to recognizing higher performance equipment. NYSERDA deserves credit for the R&D, test method and other funding that EPA and DOE should have been doing to develop higher performance equipment. These parts of the new EPA rule will help give consumers more options to buy cleaner and more efficient devices.

Stove emission standards: As expected, the EPA is staying with the de facto status quo for the next 5 years, at 4.5 grams an hour (g/hr). The 2 g/hr standard for stoves as of 2020 is fair and reasonable. As the EPA explained in the rule “nearly 90 percent of current catalytic/hybrid stoves and over 18 percent of current non-catalytic stoves” already meet the Step 2 emission limit of 2 g/hr. We hope that those manufacturers who have to redesign stoves use the opportunity to redesign to use cordwood and to reduce start-up and fugitive emissions. The optional Step 2 certification test for cordwood at 2.5 g/hr represents a very creative and positive approach by the EPA to move towards required cord wood testing.

Some independent stove and boiler companies played a vital role in broadening the debate and sharing key data sets that enabled the EPA to show that some stoves can already meet the Step 2 standards of 2 g/hr with cordwood. We are pleased that companies who participated in the 2013 Wood Stove Design Challenge helped the EPA and OMB understand that smallest manufacturers can undertake the R&D to make very clean and affordable stoves that operate well on cordwood.

Key issues not addressed: Some of the most important issues with wood stoves are difficult to address in regulations, such as indoor air quality from fugitive smoke and the ability for homeowners to reduce air-flow so much that the stove smolders for hours on end, which is often a nightly occurrence. Ultimately, we believe that some types of automation are needed to prevent the widespread consumer misuse of wood stoves. The attempt by the EPA to set a maximum emission level while the stove is on its lowest burn rate was a good start. We had urged the EPA to more formally address alternative tests for automated stoves that hold tremendous promise to reduce widespread poor operation by consumers.

Warm air furnaces: Delaying the standards for all warm air furnaces for 1 - 2 years was a mistake because some companies have little ability or intention of meeting the Step 1 standards. An interim measure after 6 months to distinguish between companies on their way towards meeting standards and those who aren’t would have been far better.

Exempt wood stoves:
We are very pleased to see that the era of exempt wood stoves is over. About 1 out of every 3 or 4 new wood stoves sold in America has been exempt in recent years and EPA had considered a weaker standard for them, but is now holding them to same standard as all other stoves.

Masonry heaters:
The EPA was not able to set standards for masonry heaters but we are glad to see that the EPA has charted a path forward to work with the Masonry Heater Association so that masonry heaters become a certified appliance category

Sell-through period: The sell-through period, set at 8 months through December 31st is fair for certified wood stoves, pellet stoves and qualified or EN303-5 approved boilers, but too long for exempt wood stoves and traditional outdoor boilers which should have come off the market sooner.

Electronic reporting: We were very glad to see that the EPA will begin electronic reporting for stove certification tests and provide more transparency for the public and access more data that is not Confidential Business Information (CBI) about stove tests.

Efficiency: Achievable efficiency standards are important in the near future and we are pleased that the EPA will finally require the manufacturers to test for, and report actual efficiency numbers not only to the EPA, but also on their websites. In practice however, many existing stoves many not have to retest for 3-5 years and it is unclear if they will have to disclose efficiency before then, unless they do it voluntarily. This is particularly important for boilers and pellet stoves that have a very wide range of efficiencies.

Renewable energy: We are very disappointed that the EPA did not mention the term “renewable” in this rule. The EPA Office of Air and Radiation should take into consideration that this sector has potential not just to make cleaner energy, but to use a renewable energy source and displace fossil fuels. Governor Cuomo’s Renewable Heat New York is investing tens of millions into the sector and integrates the goal of driving down emissions, driving up efficiency while replacing fossil fuels and offering homeowners an affordable, renewable heating source. In addition to setting minimum emission standards for lab testing, the EPA should adopt a more integrated approach to this technology that is being increasingly adopted not just by New York, but by other states as well.

In conclusion, the EPA crafted a fair and balanced rule overall and took some important steps towards testing with cordwood and recognizing those companies who take steps to build stoves based on how consumers operates them. In the long run, this new rule will result in cleaner appliances and a better foundation for renewable wood and pellet heating.
