May 15, 2020: a historic day for wood heat technology

The end of an era for some iconic stove models and the beginning for others
Quadrafire's Mt. Vernon AE is
one of many popular, iconic stove
lines going out of production 

Ten years in the making, modern wood heater emission standards are finally here, today on May 15. Hailed by many and derided by many, May 15 brings to a close a major chapter  in the book of wood heater regulation- though not the last chapter by any means. The EPA, industry and states continue to work on cordwood test methods, parts of the Hearth, Barbecue & Patio Association (HPBA) lawsuit are still outstanding, and public comment will soon be open about a likely proposal for a fall sell-through of Step 1 stoves.

To draw an analogy from biology, today marks a mass extinction of heater models unparalleled since the 1988 – 1990 period when even more heater models died off because they could not meet basic emission standards. The largest genus of stoves to die off back then was the Fisher family of stoves, though they live on in tens if not hundreds of thousands of American homes.  A few that go extinct today are also akin to famous dinosaurs, like the Ashley circulator line of stoves, that appear to lack a 2020 compliant version for wood.  Granted, some of the most iconic stove models quietly slipped out of production years ago, like the Acclaim, Intrepid and Vigilant, which have sold more units than most current models ever will, between their catalytic and non-catalytic versions.

For pellet stoves, May 15 marks the end of the Whitfield era.  Whitfield pellet stoves are still renowned for their simplicity and durability and they lived on via the Montage model made by Lenox and then by IHP.  As of May 16, Jerry Whitfield’s legacy is alive and well in the history books but gone from showroom floors.  The Mt. Vernon AE, another classic and popular pellet stove made by Quadrafire is also gone the way of the dinosaur, (the company continues to build the slightly similar Mt. Vernon E2).
The classic Jotul F 602 endures
with a 2020 compliant version

Then there are stoves like the classic Jotul F 602 that was popular when it was introduced in the 1930s. It’s virtually identical looking modern version is 2020 compliant, and still popular. 

The millions of dedicated, experienced wood stove enthusiasts in the US may be a nostalgic lot, who fondly remember the old models and the days when emissions limits were not as strict.  But May 15, 2020 is also a milestone in stoves becoming cleaner and more efficient, a point that often seems to get lost in the acrimony about the how the EPA is managing the process.  

It’s tempting to say that the 2015 wood stove rules, that culminated today in a 2 to 2.5 gram an hour standard, will give the stove industry a new lease on life, like the 1988 EPA regulations did.  The jury is still out on how much better these stoves are than the ones allowed to emit up to 4.5 grams an hour and some models were likely brought to market too quick, before they were sufficiently field tested.  Instead of touting the new prowess of these cleaners stoves, almost all industry leaders have  been saying there is no appreciable difference between a 2-gram standard and a 4.5 standard.  Part of this is a messaging tactic to oppose stricter standards or possibly they know more about how test labs can produce ever lower emissions data from virtually the same stove.   

The sell-through that kept falling through

The May 15 deadline was a sour one for many retailers and industry members who thought that there would be a sell through.  First, the EPA raised their hopes by proposing a sell-through in 2018, only to reverse course and deny it in March 2020.  The March ruling was a blow to industry morale even though the EPA agreed to publicly tell industry in October 2019 that they should stick to the original
Senator Carper (D-DE) has emerged

regulations in the Senate
timetable.  Then HPBA rallied again in March 2020, apparently thinking they could get a Direct Final Rule, allowing a sell-through starting on May 16, and everyone’s hopes went back up again.  And, Mandy Gunasekara was back at the EPA, after more than a year absence. But Direct Final Rules are for non-controversial changes that won’t be opposed by any stakeholder.  Senator Carper from Delaware quickly made sure that they EPA knew how contentious a sell-through was.  

It wasn’t until early May that it became clear to HPBA that getting a Direct Final Rule was like threading a needle in a hurricane, even with some high-ranking friends in the Trump Administration.  Then, HPBA seemed to quickly change course, urging industry to ignore the possible sell-through that they had fought so hard to secure.  HPBA unveiled a promising  Stoves to Homes Initiative that would allow retailers to give away their unsold Step 1 stoves to a charity who would then install them in low-income homes.   [Update: At 5:00 PM on May 15, the EPA released the details of a proposed sell-through window in the fall, ending on Nov. 30, and after public comment and an online hearing.]

HPBA worked hard on behalf of its membership on all three branches of government: Congress, the courts and the Administration.  HPBA came extremely close to victory in Congress, passing a far-reaching three year delay Bill in the House, championed by Rep. Collin Peterson (D-MN) who represents Central Boiler's district.  This was far more than a retailer sell-through and industry could not secure support from key democrats in the Senate when the initiative failed.  Many assumed industry could secure relief from the Trump Administration, as so many other industries have, and the 2018 EPA sell-through proposal was the fruit of those efforts.  Some speculate that the 2018 departure of EPA official Mandy Gunasekara left HPBA without a high-ranking benefactor to shepherd through the sell-through proposal.  It may have been left to lower

level EPA staff who sided with states and air agencies that the case for a sell-through was weak.  What the EPA may have failed to grasp, was that even through many stoves were certified to 2020 standards in 2016, 2017 and 2018, many manufacturers did not make those models available to retailers until later in 2019, leaving retailers no option but to continue buying Step 1 models until the very last heating season.  

Finally, in the third branch of government, the courts, HPBA’s legal strategy seemed to unravel as it requested extension after extension and as time passed, more and more stoves were certified to the 2020 standards, including the 2.5 gram an hour cordwood standard. HPBA had a strong claim the EPA lacked sufficient data to set a cordwood standard, but then its members began favoring the looser ASTM cordwood standard.  After 5 years of advocacy, industry had little to show to the retailers, many of whom are now angry.  

Fortunately, 2018 and 2019 were mostly good years for much of the manufacturing and retail industry, according to a number of detailed articles in Hearth and Home Magazine.  The wood and pellet heater industry entered 2020 on decent footing, though many manufacturers and retailers increasingly make profits from their gas and electric lines of appliances, not wood and pellet.  Then the coronavirus hit with a broadside slam that appears to be lingering not just through the spring and summer, but potentially could have a major negative impact in the fall of 2020 and well into 2021.  The pellet stove and boiler sector is also particularly susceptible to low oil prices, which simultaneously accompanied Covid-19 in its swath of destruction through the economy.

In addition, the industry’s right-leaning, anti-regulatory tilt has built friends in Congress and the Administration, but not necessarily with the leaders of the renewable energy movement, who seem to be increasingly looking to electrify residential heat. Privately, many HPBA members say they wish the association had not tried to fight the regulations so hard, even though the outdoor boiler and warm air furnace sectors were pushing them to do just that.  If Senator Biden is elected in November, industry would likely do well to try to quickly reposition themselves and be part of coalitions that could stand to benefit from a pro-renewable administration.  Pellet heating technologies should be best positioned to benefit from some form of green new deal and potentially help end the difficult, cyclical boom-bust nature of pellet heater sales.

Certified stoves on May 16
 
A screen shot of the EPA database on
May 15, showing 610 certified stoves.
The number of stoves on the EPA’s list certified room heaters is about to plummet downward, from 610 to 211 stove models.  Hundreds of models that design firms, engineers, lab technicians, production line workers brought to market, will be things of the past.  They represent millions upon millions of stoves that families gathered around in the evening, that kept them warm during power outages, and helped them save enough money for groceries and other essentials.  My grandparents, my parents and my family used many of those stoves, considered to be the best technology of their era.  One of them, a pellet stove made in 2014 and has worked beautifully since then, heats my home as a I write this.

So we put our faith again into the hands of the engineers and lab techs to come up with even better stoves, that will be even cleaner and more efficient. We won’t see the huge PM reduction and efficiency gains that we experienced in 1988- 1990, but chopping lab numbers in half, from 4.5 to 2 or 2.5 grams is no easy feat and should be embraced by all of us.  We should applaud the engineers who do this for us, and especially those who are working not just to achieve these numbers in a lab but who are trying to ensure stoves are cleaner in our living rooms.

is movig forward.

Reducing average stove emissions by a gram or two or three per hour from a stove is a major achievement that will protect the lungs of not just those that buy stoves, but their kids, their parents, their grandparents – and their neighbors.  Granted it will take decades for these cleaner and more efficient stoves to be commonplace in homes across America.  After all, there are still millions of uncertified, pre-1988 stoves in homes.  

But we should not forget that the drop to 4.5 grams an hour actually happened more when Washington State changed their standards in 1995, than it did in 2015 when the EPA adopted that change.  Those two decades of sales of cleaner stoves all across America were a blessing that has had long-term ramifications.  Two decades from now, I hope we will be able to look back and appreciate the engineers who designed these cleaner 2020 appliances and gave a new lease on life to this vital renewable energy technology.

HPBA 2020 Expo showcases all new stoves to smaller audience

Jack Goldman, right, opens the 2020
Expo in New Orleans.
Updated, April 9, 2020: The hearth industry’s annual marketplace for manufacturers and retailers concluded on March 14th, a half a day early in New Orleans amidst a dwindling crowd and growing concern about the spread of Covid-19. This was the first hearth industry gathering since the late 1980s in which virtually all the stoves and boilers on the floor were newly redesigned and tested to meet stricter emission standards.  

Some manufacturers were clearly proud of what they felt were genuinely cleaner stoves while others were unconvinced or cynical of the new standard’s impact in the real world. 
Mark Shmorhun of the DOE's
Biotechnology office
attended the Expo to talk to
manufacturers about R&D
funding needs.

Due to Coronavirus concerns, Travis and Jotul, two large manufacturers, pulled out at the last minute, leading to a notably smaller Expo. U.S. Stove, having dropped their HPBA membership, decided not to attend this year, presumably because their inability to meet the 2020 emission standards on most of their appliances weakened their position in the hearth industry.  US Stove has 18 stove models that are 2020 compliant but no 2020 compliant furnaces yet, an area it had once domoniated.  US Stove responded to this blog, saying they are well positioned to move forward with a broad range of new and exciting products.

From the perspective of the Alliance for Green Heat, the 2020 Expo showcased several notable trends, some encouraging and others troubling.  

Vesta gives Best in Show award to an automated wood stove

Possibly the biggest highlight for AGH was seeing automated stoves take more of a foothold in the marketplace. Napoleon’s Eco Smart wood stove won Best in Show at the Vesta Awards, marking the first time that an automated stove won a Vesta Award.  The stove has an optical sensor that monitors particulate matter and can continually adjust air settings to produce a cleaner burn. According to Napoleon, the automation will only add $300 to the price and they expect the complete system with stove to retail for about $2,500. The stove also connects to the Napoleon cloud via the user's smart phone so they can monitor combustion conditions. The user can also allow the company to log data from the stove, providing a valuable record of how the stove runs. The stove is not yet EPA certified, but should be within months. 
The Charnwood Skye 2700, expected to
retail for about $3,300, several hundred
more than its non-automated cousin.

Charnwood, a British manufacturer, also was a finalist in the Vesta award, with their Skye E2700, also an automated stove that does much of what the Napoleon does, but with different technology.  Charnwood will be entering the US market for the first time later this year with this stove. Hugh Wells, head of the Britsh company told AGH, "We are very excited about this product because it does revolutionise how we burn wood by taking out user error." CFS-Teco did the certication testing in Portland and it achieved 78% efficiency, the highest of any non-cat. 

SBI should also have an automated stove on the market within a year, and MF Fire had their automated Catalyst on display at the Expo and have another one in development.  Maxitrol also exhibited a prototype of an automated stove and says that they are taking off in Germany.  Napoleon also won a second Vesta award for their novel "Heat & Cool Electric Fireplace," a mini-split heat pump housed in an electric fireplace.  

2020 stove trends

The 2020 NSPS has resulted in many more catalytic and hybrid stove models. AGH is particularly

happy to see more hybrid models as they help reduce start-up smoke and provide back-up secondary combustion if the operator does not engage the catalyst. A more unnoticed trend is the rapid adoption of the ASTM E3503 cordwood test method. Data from the EPA list of stoves shows the average grams per hour for cordwood tested stoves is 1.6 grams – the exact same average for crib tested stoves. About 45% of all 2020 certified wood stoves were tested with the ASTM cordwood method, which reportedly has more flexibility in its parameters making it easier for manufacturers to pass the certification test. Nearly all of the smaller non-cat stoves were tested with cordwood. Quite a few very affordable stoves that sell primarily in big box and hardware stores are passing the 2020 standards, and some stoves barely had to undergo any redesign.  

A sophisticated, lower priced electronic precipitator
ESPs for wood stoves, considered
far-fetched just a few years ago, are
improving rapidly and popular in
Germany and Switzerland. 

Danish manufacturer Enervex brought a self-cleaning electronic precipitator, known as an ESP. They are commonly used by factories and restaurants, but now small and affordable enough for residential applications. ESPs are a type of scrubber that uses static electricity to remove particulate matter from exhaust fumes before the particulates exit the smokestack. Enervex’s innovation is to design a residential ESP that is self-cleaning, often a big problem, and to bring the price down. They expect theirs will sell for $1,200- $1,600 when it comes on the US market. There is a quickly growing market for them in Germany, now that they are recognized by the country's eco-label, Blue Swan, and some cities may require them. OekoSolve, a Swiss company, made the ESP being tested in Fairbanks.

HPBA recruits Appalachia Service Project to take 2015 stoves in May

To address the fate of potentially hundreds of wood stoves that are 2015 certified but not allowed to be sold after May 15, 2020, HPBA negotiated with the EPA to allow retailers to donate stoves to a non-profit who can them install them. HPBA is teaming up with the Christian ministry Appalachia Service Project, based in Tennessee, who repairs homes in Central Appalachia, making them warmer,

safer, and drier. At the Expo, AGH met with Adam Bean,
Home Repair Coordinator for the group, 
who is quickly learning about wood stove installations and trying to estimate how many stoves his group has the capacity to install, which will partly depend on securing donated NFI installing and training.

Pellet stoves out of the limelight

Even though pellet stoves were relatively easy to redesign and test at 2 grams an hour or lower, the market for pellet stoves has not been particularly good and there were not many on the Expo floor. There were no pellet stove finalists in the Vesta Awards, which may indicate a pause in innovation in the North American market.

EPA announces final NSPS rule during Expo

On the first day of the conference, the EPA formally announced that they would not allow a retailer sell-through. The EPA had said on October 15, 2019 that entities should follow the compliance dates but some felt that there was still a chance for a sell-through. HPBA expressed its disappointment in a written statement while the Pellet Fuel Institute claimed a victory because the EPA removed minimum requirements from pellet fuel while retaining the prohibition that pellet fuel must not contain any of the prohibited fuels listed in the 2015 NSPS. There remains considerable debate about whether the 5-year timeline would have been enough if manufacturers had started redesigning and testing to the 2020 standards early in the process. Key excerpts of the EPA ruling provide detailed insight into why the EPA did not allow a sell-through. Some did start early and began offering 2020 compliant models to their retailers as soon as 2018, while most did not start releasing 2020 models until 2019 or even this year.  The issue was far more complicated because manufacturers had large inventories of 2015 stoves and some needed the cooperation of retailers to buy their 2015 inventory well into 2019. An HPBA mailer to retailers in 2019 said: “retailers and distributors should NOT immediately stop buying anything that doesn’t meet Step 2” in part because there wasn’t enough variety and in part because manufacturers still needed revenue from sales of their 2015 inventory.

EPA holds 3-day wood smoke workshop

One of the main reasons AGH attends the annual HPBA Expo is to participate in workshops

organized by the EPA on wood smoke reduction strategies. This year 
the workshop was coordinated and supported by EPA's Burn Wise, the Western States Air Resources Council (WESTAR), the Northeast States for Coordinated Air Use Management (NESCAUM) and National Tribal Air Association (NTAA) and was going to be the largest one ever, with nearly 100 federal, state, local and tribal participants registered.  But some states like Washington banned their employees from travel and many other participants cancelled, leaving a group of about 60. The workshop mainly consisted of a series of talks and powerpoints about change out programs, cord wood test methods, the impact of the NSPS, DOE funding opportunities for stove R&D, retrofits and ESPs, low cost consumer air quality sensors, indoor air quality issues, addressing wood smoke complaints, etc. Most of the powerpoints can be dowloaded here. AGH also hosted a gumbo and etouffee networking reception on Frenchman Street for all the participants. 


The 2021 HPBA Expo is scheduled for March 4-6 in Nashville, Tennessee.

Nearly 20% of stoves meet new emission standards; wood boilers lag behind


By John Ackerly and Melissa Bollman, Alliance for Green Heat

Of the 518 wood and pellet stoves currently on the market in the US, 91 or about 18% are certified to the stricter emission standards that are set to take effect on May 15, 2020. In general, smaller companies with fewer models tend to be more prepared for the 2020 deadline than larger companies with many models. Pellet stoves can meet the 2020 emission standards relatively easily, and some companies that make only pellet stoves have fully 2020 compliant product lines. [Update: as of May 2019, 25% of stove models are 2020 certified and now can be easily viewed on the EPA's new searchable database of certified stoves.]

While more and more wood and pellet stoves are meeting the new emission standards, American wood boiler companies are still struggling to make boilers clean enough to be certified to 2020 standards. The wood heater industry appears to be waging legislative and legal battles that will benefit the outdoor wood boiler industry the most. For the wood stove manufacturing community, a sell-through for retailers appears to be the most important type of relief. The Alliance for Green Heat supports no more than a one-year sell-through for wood heater retailers.

Meanwhile, Senators are preparing an amendment or bill that would provide $75 million a year for 6 years for a national change-out program fund, a staggering amount of money that could spur sales of 2020 compliant stoves. The bill also contains a one-year sell-through provision for retailers. Industry is not supporting this amendment as of now, opting for a bill with 3 year delay of NSPS deadlines without any funding for change outs.

One dilemma underlying the transition to stricter standards is that manufacturers are still recertifying virtually all of their stoves with cribwood, not cordwood. Thus, the opportunity to shift toward stricter emission standards with the fuel homeowners use—cordwood—was not achieved with the 2015 NSPS. Even if industry succeeds in getting a 3-year delay for the standards, it is not at all certain that manufacturers will opt to test to cordwood standards. Until one or more states or incentive programs require stoves to be certified with cordwood, there may be little incentive for manufacturers to test with a cordwood protocol.

Stove compliance trends


The latest list of EPA certified stoves reveals that about 13% of stove companies have fully 2020 compliant product lines. (This figure includes only stove manufacturers that produce at least two EPA certified models.) Most company product lines are between 5% and 30% 2020 compliant, but several popular companies, including Jotul, Kuma, and Napoleon (Wolf Steel), do not currently have any stoves listed on the EPA list that meet the Step 2 emissions standards. Wood heat retailers currently do not have a sell-through period to sell their existing stock once the Step 2 emission standards take effect in May 2020, but the EPA recently proposed changes to the NSPS that are likely to give retailers a sell-through period.


2020 compliant models produced by large manufacturers
How to read this chart (click to enlarge): This chart shows the number of 2020 compliant wood and pellet stove models produced by large manufacturers (manufacturers that produce at least eleven EPA certified models) as bars on the primary (left) y-axis and the percentage of models the manufacturers produce that are 2020 compliant as a point on the secondary (right) y-axis.

Several smaller pellet stove manufacturers’ product lines are entirely 2020 compliant. The chart below shows the number of 2020 compliant models produced by smaller stove manufacturers (manufacturers are considered small if they produce between 2 and 10 certified stoves on the EPA list; manufacturers with only one EPA certified wood or pellet stove in production are not included.)



Furnace and boiler compliance trends 


The wood and pellet boiler and furnace industries appear to be exhibiting similar patterns. Only ten (9%) boiler models (eight cordwood and two pellet) and one forced-air furnace, a cordwood model by Lamppa, are certified as 2020 compliant, according to the EPA lists which were last updated in June.

Some boiler and furnace manufacturers are planning to stop manufacturing boilers or leading an aggressive campaign not only to delay the 2020 standards but also to significantly weaken emission standards for outdoor and indoor wood boilers.


How to read this chart (click to enlarge): This chart shows the number of 2020 compliant models produced by hydronic heater manufacturers. It includes both the number of 2020 compliant models listed on the EPA list and the number of models that emit under 0.10 lb/mmBtu (crib wood or pellets) or under 0.15 lb/mmBtu  (cord wood) but need to be retested before they are 2020 compliant. This chart only includes boiler manufacturers that produce at least three certified models on the most recent EPA list.
