Company makes 2020 certified warm air furnace for under $2,000 - and stirs controversy


Paul Van Der Eems, Dan Haynes,
and David Walters of HY-C accept
a Vesta Award for their furnace.
Updated on April 5, 2019 - Many said it could not be done.  A competitor called it “preposterous.” But HY-C, a Missouri company that makes a budget line of warm air wood-fired furnaces, is well on their way to being ready for June 2020, when stricter EPA regulations come into effect.  

Their first 2020 compliant model, their smallest unit, was certified at 0.106 lb/MMBtu Output, well under the .15 allowable. The suggested retail price is $1,899 which is only $100 more than the previous unit that was certified to the 2017 standards.  HY-C won a Vesta Award for the furnace at the industry’s annual expo in Dallas last week.

In 2014, HY-C went to the EPA and urged them to adopt a laddered approach, giving companies several years to get certified and several more to meet a stricter standard. “The EPA was responsive, giving us a total of 5 years,” David Walters, President of HY-C recalled in a phone interview.  David said that  when they bought the company in 2011, the NSPS process was well underway, and they knew they would have to change and clean up.  “It wasn’t easy, but we did it, and that is good for the environment, for consumers, and for us, the manufacturer,” David said.

The HY-C FC100E is the first
low-cost wood fired forced air
furnace to meet the strict EPA
2020 emission standards.
The EPA won’t list a certified unit on the list of certified appliances until the company posts their lab test report on their website.  Parts of those reports are highly technical but provide key information for consumers and others. The HY-C report said the unit achieved 50% delivered efficiency and a stack loss efficiency of 71%. It was certified using a modified test protocol that had been approved in advance by the EPA.  Intertek laboratories did the testing using about 36-pound loads of cord wood that had about 22% moisture content.  The five tests ran 3 to 6 hours.  Their target output was 13,000 – 37,000 BTUs but the certification test obtained 20,000 – 34,000, due in part to the modified test protocol. 

To date, the only other company to have a 2020 compliant forced air furnace is Lamppa Manufacturing, which hit .09 lbs/MMBtu several year ago and a stack loss efficiency of 79%, far above the HY-C.  The Lamppa unit, the Vapor-Fire 100 is currently priced at $5,695 and also obtained a test protocol variance from the EPA in the test protocol.  The Vapor Fire weights 670 pounds, which may indicate thicker and more durable materials compared to the HY-C unit at 435 pounds.  (Update: SBI has certified a third wood furnace, under the Caddy brand.)
The Lamppa Vapor Fire
100 is the only other 2020
compliant wood furnace,


Another big player in the forced air furnace space is US Stove, and it’s unclear when they will have a 2020 compliant unit.  Of their eight units certified to the 2017 standards, one came in at 33% efficiency and an average of 60% efficiency. US Stove is urging the EPA to repeal the Step 2 standards for forced air furnaces, arguing that agency picked a “compliance limit out of thin air with not [sic] real data to support it.”  In a filing with the EPA, they said that the EPA’s timeline of going from an uncertified appliance category to meeting .15 mmBTU “is preposterous and unrealistic.”  HY-C appears to have just proved otherwise.

However, the willingness of the EPA to approve alternative test methods can be controversial, and companies often claim a competitor got an unfair advantage with a particular variance.  The EPA is not supposed to approve variances that make the protocol easier to pass, but that may just what is happening in some instances.  Variances are a critical tool for the EPA to allow for innovative products to be fairly tested and they also create a precedent for others to receive similar variances.

The largest player in the Canadian forced air furnace market is Stove Builders International (SBI) and they do not directly compete in the budget market with US Stove or HY-C.  SBI is also working on certifying furnaces to the 2020 standards but “we are trying to achieve the desired performance without using the alternative test method that the EPA has granted to others,” said Marc-Antoine Cantin, of SBI.  “We want to put out a product that cycles combustion and doesn’t just cycle the blower, while the unit is kept burning at a single burn rate,” Cantin said.  

HY-C sells their furnaces through a variety of distributors and retailers, including many big box stores. They provide all of their own customer services and have tens of thousands of units in the field that provide them with intensive customer feedback.  They make all of their furnaces in St. Louis Missouri and have extremely little inventory of non-2020 inventory left and expect to start shipping 2020 compliant units in July.  “We worked hard with distributors, so the pipeline of older units is dry,” Walter told us.  As a result, they have abstained from the debate as to whether the wider industry needs a 2-year sell through for units that are not 2020 compliant.  Lamppa has been an outspoken defender of the original timelines, arguing that a 2-year sell through would be unfair.

capacity" at Home Depot (Home
Depot discontinued the unit
a week after the story appeared.)

Both US Stove and HY-C say that their customer base is very price sensitive and need a furnace under $2,000, if not close to $1,500.  Other industry experts have questioned how so many people came to expect a whole house furnace for less than the price of an average wood stove and assumed that price would have to climb substantially to meet 2020 emission standards.  At the core of the fight between industry, states and air quality agencies is whether the price of wood appliances and costs to manufacturers should drive EPA standards more than other factors.  While HY-C was able to meet both the timeline and the emission standards, it is still unclear how well it will be received by the general public.  US Stove also make “coal only” units that are exempt from EPA emissions and sell side-by-side in many stores with the regulated wood units. HY-C has a coal only unit but only sells a few each year direct to consumers and not through retailers.

According to one industry insider, Tractor Supply Company stores is the biggest seller of wood furnaces from their 1,700 US stores.  Floor staff at chain hardware stores like this have reportedly been trained to inform consumers that the “coal only” units can burn wood perfectly well.  Companies that make both wood and coal units benefit from this and can sustain market share, even as EPA standards tighten.

Certifying to 2020 standards appears to have led to shorter burn times and more finicky furnace and boilers for some units.  HY-C advertised up to 12-hour burn time and a maximum of 130,000 BTU output for the unit as certified to 2017 emission standards.  The EPA listed BTU output up to 45,000.  The 2020 version only had up to 6-hour burn times in the lab and a maximum of 34,000 BTU output.  Both the 2017 and the 2020 model accept 20-inch logs.  Can the 2020 version meet consumer expectations at virtually the same price? 

But for now, HY-C achieved what they set out to. “We planned to build a better mouse trap and we feel that we succeeded, with advice from industry experts and our consumers,” David Walter said.  “In America, we should not take for granted that we have clean air and water, thanks to Congress and decades of work by the EPA,” Walter continued.  If anyone thinks the EPA efforts are a waste of time, Walters says all you have to do is visit Shanghai or some other foreign cities. “It’s so polluted you can barely walk outside and see the other side of the street,” he said.

Gravity Fed Pellet Stove Wins Vesta Award

Gap 2020
Updated: May 2022. After years of development, a company finally produced an EPA certified pellet stove in 2013 that needs no electricity.  The stove was developed by an Oregon company, Wiseway from which the stove takes its name, and then the company was bought by US Stove, who improved its design. The unit uses natural draft for the air and gravity to feed the pellets into the combustion chamber.


The designer of the Wiseway, Gary Wisener, has now built another EPA certified gravity fed stove with a partner, Gene Bradley, who owns Smokey's Stoves in Oregon.  The Gap 2020 is designed for off-grid and has many valuable features such as a cooktop and an attachable one and hot water reservoir.

US Stove owns another brand, Breckwell, which now also makes a gravity fed stove called the Traverse. The Traverse is 2020 certified, but it reportedly had quality problems with welding, which hopefully are fixed by now.

Many gravity fed pellet stoves are on the market in Europe, including ones by Tulikivi (Finland), Yola (Ireland), Koppe (Germany) and Altech (Netherlands). Click here for more on gravity fed pellet stoves.
The Wiseway


For decades, one of the main drawbacks of pellet stoves has been that they don’t work in a blackout because they require electricity. And, with so many moving parts, pellet stoves often break down and need much more maintenance than wood stoves. 

When the stove started to sell in 2013, quite a few customers had problems with it, including the pellets in the hopper catching on fire, also known as a “burn back.”  The stove has been redesigned.

(If you are looking to buy a pellet stove, check our "6 tips to buy the right pellet stove" based on independent research.)

The launch of the Wiseway illustrates a much wider problem in the stove industry: a lack of reliable, independent product reports that assess consumer satisfaction and reliability.  Even if consumers spend lots of time on the Internet reading various consumer reviews on sites like Hearth.com, it is still very difficult to get a sense of how common the problems are and what overall rating a product should have.  Hearth.com has several threads on the Wiseway that are worth reading if you are considering purchasing one.  

Consumer Reports once did a very limited review of 6 pellet stoves, in which they recommended two.  The review did not even mention emission rates, nor did it test for fan or augur noise, other common issues that consumers have with stoves.  The Wiseway has no fan or augur noise, which is a big plus for some consumers.  Moreover, the stove has a very respectable emission rate of 1.9 grams per hour.  Equally important, it was EPA certified in 2014 during a time where pellet stoves were not required to get certified.  EPA certified pellet stoves are likely to be more efficient since many, if not most, uncertified stoves pour excess air through the stove, which can significantly reduce efficiency. 

The Wiseway has an EPA verified efficiency of 69%, higher than some more expensive pellet stoves that use electricity.   Many pellet stoves have efficiencies under 70%. The Alliance for Green Heat advises consumers to rely on the efficiencies on the EPA list and find one is that is 75% efficient or higher to get the federal tax credit which is 26% in 2022 and 22% in 2023 which includes all installation costs as well.

There is clearly a large market niche to be filled by a gravity fed pellet stove and Wiseway is the first one out of the gate.  We suspect there will be competitors in coming years and that competition is likely to lead to better and better products.
