Fourth Wood Stove Competition to focus on automation and electricity generation

Posted by Earth Stove on February 26, 2017 with No Commentsas , , , , , , ,
Today, the Alliance for Green Heat announced the fourth Wood Stove Design Challenge, returning to the National Mall in Washington, DC in November 2018. 
The 2018 event will be free and open to the public and includes rigorous testing of the next generation of technology that can make wood stoves consistently cleaner, more efficient, easier to use and, like solar energy, a renewable source of electricity.
The fourth Wood Stove Design Challenge is modeled after the Department of Energy’s (DOE’s) Solar Decathlon, a competition between teams from universities worldwide to design more efficient and cheaper residential solar power.  Like the Solar Decathlon, the Wood Stove Challenge also attracts teams from around the world and focuses energy and resources on innovation and improved performance.  The stove competitions have been in partnership with the DOE Brookhaven National Lab, the New York State Energy Research and Development Administration (NYSERDA), the US Forest Service and others, the Osprey Foundation, among others. 
Participants will compete in two events:  One is to automate the wood stove with 21stcentury technology like sensors and WIFI-enabled controls that improve combustion efficiency, reduce air pollution and improve ease of use.   The second competition will focus on thermoelectric wood stoves that generate electricity to power lights, cell phones, and WIFI-enabled controls. Thermoelectric generators are similar to solar PV systems except they turn heat instead of light into electricity.  When integrated with a residential solar PV system, a thermoelectric wood stove and battery power system, like the TESLA Powerwall, could effectively double the wintertime output of solar PV system in areas like northern United States, Canada and northern Europe.
Wood stoves are still used by 30 – 60% of homes in hundreds of rural and suburban counties around the country.  Yet, the technology revolution that has swept household appliances in the last 20 years has by-passed wood stove technology. 

Teams in the 2018 stove challenge will be competing for up to $ 50,000 in prizes.  The teams and exhibitors will also have a chance to showcase new technology on the National Mall just blocks away from the Department of Energy, the US Department of Agriculture and the Environmental Protection Agency. 
“This is a chance for students, back yard inventors, and wood stove manufacturers to re-invent this age-old technology for today’s environmentally conscious and time-conscious consumer,” said John Ackerly, founder of the Wood Stove Competition and President of the Alliance for Green Heat.  “An affordable, smart wood stove is achievable and could help millions of families reduce their reliance on gas and oil while significantly reducing  pollution,” Ackerly added.
“This is the first Wood Stove Challenge to promote wood stoves that generate electricity to power everything from a cell phone to an entire home.  Thermoelectric wood stoves, when integrated with solar PV systems and home batteries like the TESLA Powerwall, have the potential to make solar energy more affordable, reduce air pollution, and pave the way for a more sustainable energy future, “according to Ken Adler, Senior Technology Advisor at the Alliance for Green Heat and formerly with the U.S. EPA.
Previous Stove Design Challenges brought innovative stoves and a diverse array of stove and energy experts together on the National Mall in 2013, Brookhaven National Lab in 2014 and 2016.
Further details about participating and competing in this competition will be available late March, 2017.

Wooden and pellet stove rates increase 3% in wake of new EPA laws

Posted by Earth Stove on February 24, 2017 with No Commentsas , , , , , ,


Since the EPA declared stricter emissions rules for wood and pellet stoves, charges increased by an average of 3% more than a two-12 months time period when altered for inflation, based mostly on a evaluation of seventy seven common stove versions. Without having inflation, prices enhanced by an average of four%.

The Alliance for Eco-friendly Heat, an impartial non-revenue targeted on the wooden and pellet heating sector, tracked retail charges for 77 wood and pellet stoves in excess of a two-12 months time period, from February 2015 to February 2017. The EPA introduced new rules on February third and they took effect on May 15, 2015. Even stricter emission boundaries are set for 2020 and the Alliance will continue to monitor charges by way of 2020 and outside of.

We determined seventy seven stoves produced by seven well-liked brand names with varying value points: Jotul, Blaze King, Harman, Quadrafire, Woodstock Soapstone, Hearthstone, US Stove, and Englander.

It is unattainable to explain to how much rules contributed to the 3% cost rise, although every of the 7 makes are likely by way of durations of improved R&ampD as they work toward complying with the 2020 emission limitations. The EPA established a greatest of seven.5 grams an hour in 1990, four.five in 2015 and 2. or two.five grams in 2020. Most stoves currently achieved the 4.5 gram restrict in 2015, but most do not meet up with the 2020 restrictions. It is attainable that some firms are commencing to go those costs alongside to buyers.

There may be steeper cost rises as 2020 ways and organizations have to commence far more intensive R&ampD and certification tests. &nbspHowever, industry is pushing a invoice in Congress to delay the 2020 emission standards to 2023. &nbspThe Fireside, Patio &amp Barbecue Association is also suing the EPA to block the 2020 emission requirements for boilers and furnaces, but not essentially for stoves. &nbspThe monthly bill in Congress is partially created to give the litigation sufficient time to get by means of the courts. &nbsp

We tracked the retail prices of fifty nine wood stoves and 18 pellet stoves making use of the sale or last price of the stove outlined on the retailer’s web site. General, the fifty nine wooden stove retail rates rose an common of four% ($ eighty) or 3% ($ forty five) when accounting for inflation. The pellet stove classification observed a greater average value enhance of 5% ($ 106) or 3% ($ 66) for each stove when accounting for inflation.

  • Four-fifths of the seventy seven wooden and pellet stoves enhanced in value more than the two a long time. Of these, the typical cost enhance was 6% ($ one hundred twenty five) or five% ($ 90) when modifying for inflation.
  • About one-fifth of the seventy seven stoves did not go up in value in between February 2015 and 2017. The vast majority of the Englander and Blaze King models we tracked stayed the exact same cost.
  • Four wood stoves out of seventy seven wooden and pellet stoves — one particular Jotul, two Hearthstone, and one particular US Stove — declined in price tag. The common decrease was 6% ($ 250).

The EPA is needed by law to do an economic regulatory impact evaluation (PDF) and establish if the expenses of the regulation outweigh the positive aspects. The EPA predicted a bit higher retail charges, and as a outcome, a slight decline in demand for new stoves. Nevertheless, on equilibrium they approximated that the general overall health and other benefits vastly outweigh the fees.

Some commentators, members of Congress and editors claimed the EPA laws would make wood stove charges rise sharply and be unaffordable for the average American.

The EPA also is necessary to assess the affect of the regulation on little firms, because much more than 90% of stove producers and stores are little corporations. The U.S. Census Bureau stories that the industry employed fifteen,911 employees in 2011.

Price tag changes by manufacturer and stove type

The wooden stoves with the maximum price tag decreases, Hearthstone’s Bari 8170 and Lima 8150, which declined in value by $ 620 and $ 300 respectively, ended up the priced the highest of any stove on our list in 2015 at $ four,999 and $ 5,299. No pellet stove we tracked declined in price tag in 2017 and the only two pellet stoves did not increase in cost in 2017 (both Englanders priced in between $ one,000 and $ 2,000).

Wooden stove price tag boosts ranged from one% (Hearthstone Castleton 8030 and Craftsbury 8391) to 35% (US Stove’s Big Woodstove). Amid the wooden stoves that increased in cost in between 2015 and 2017, the typical boost was about $ 125 or six% more than the 2015 price. Seven of the 9 pellet stoves that rose in price increased by an even $ one hundred, regardless of their 2015 price tag, which represented a three-4% increase. All five of the Harman pellet stoves, which retailed in between $ 2,999 and $ three,999 retail in 2015, have been outlined $ a hundred larger by the same retailer in 2017.

For the sake of consistency, we only employed stove charges at a single or at most two retailers for every brand name. We employed ultimate or sale charges fairly than “suggested retail price” or “regular price” when offered. The quantity of stoves we selected for every brand name different dependent on the variety of designs available in 2015 and the amount of versions that continued to be bought by that retailer in 2017.

Englander and US Stove experienced some of the most affordable rates stoves we commenced monitoring in 2015, with a median value of about $ 1,000. At about the center ended up the brand names Woodstock Soapstone (median cost of $ two,four hundred), Quadrafire ($ two,550), and Jotul ($ two,seven-hundred). The much more pricey stove brand names integrated our study, dependent on median prices, were Hearthstone ($ 2,900), Blaze King ($ 2,950), and Harman ($ three,000).

Four out of five Blaze King stoves, a few out of 4 Englander wood stoves and all (two) Englander pellet stoves did not increase in cost over these two many years. The sixteen Hearthstone wooden and pellet stoves we tracked declined in value by an typical of one% ($ three.75) per stove, many thanks in excellent part to huge fall in cost for two of the brand’s priciest ($ five,000+) wooden stoves.

As for the manufacturers that increased their charges, Jotul’s 19 wood stoves improved by an average of 3% ($ 79) every. Quadrafire’s and Harman’s wooden and pellet stoves each increased by an average of 4% each and every ($ one hundred and one for Quadrafire, $ 122 for Harman). Harman’s wooden and pellet stoves increased in value by an average of $ 122 for every stove. US Stove and Woodstock Soapstone had the finest common value raises of any brand name at fifteen% each (Woodstock Soapstone has frequent product sales which we did not get into account). US Stove’s stove rates enhanced by an common of $ a hundred and fifty five per stove and Woodstock Soapstone’s enhanced by an regular of $ 408 for each stove.

The EPA regulations had a significantly bigger impact on charges on organizations creating unregulated outdoor wood boilers and unregulated wood furnaces. &nbspPrices for boilers rose at a sharper charge than stoves, although we did not observe individuals costs and cannot offer any estimates.

States attempt to update outdoor wood boiler laws to conform to new federal policies

Posted by Earth Stove on February 15, 2017 with No Commentsas , , , , , , , , ,

The EPA’s new wooden heater regulations has left far more than ten states with outside boiler restrictions that now want updating. Most point out rules refer to Stage 1 and Stage 2 boilers, a voluntary plan that has now been superseded by certified boilers in new EPA rules.&nbsp&nbsp

At the moment, at the very least New Hampshire and Maryland are updating restrictions and the province of British Columbia presently integrated language for the new EPA accredited boilers.

The wording in these laws is frequently difficult and several states have produced accidental results in the earlier, these kinds of as Maryland whose laws only permitted Section two outside boilers to be set up, effectively prohibiting the installation of considerably cleaner and more effective indoor pellet boilers.

Scott Nichols, operator of Tarm biomass in Orford New Hampshire, is functioning with New Hampshire officers to steer clear of unintended benefits.&nbsp 1 concern, for example, is his advice to preserve the exemption for out of doors pellet boilers from residence line set again principles, an exemption in area considering that 2010.&nbsp Most states that regulate outdoor boilers have established set backs, from fifty to a lot more than two hundred feet.&nbsp

The Alliance for Green Heat is urging states to retain or set up property line established backs for out of doors wood boilers, like the new certified kinds, given that they can nevertheless emit abnormal smoke if they are loaded with unsplit, unseasoned wooden.&nbsp “We suggest a least of fifty ft from the property line and a hundred and fifty ft from the nearest neighboring residence for qualified wood boilers and far more for non-certified kinds,” explained John Ackerly, President of the Alliance for Environmentally friendly Heat.&nbsp

As of mid-February, 2017, New Hampshire is proposing 50 foot established-backs for certified wire wooden boilers, but Maryland’s draft did not include any established backs.

Yet another concern that retailers of present day indoor qualified wooden and pellet boilers are anxious with is the definition of outside boiler. “The EPA definition is improperly written and is a dragnet that catches each and every boiler in existence given that any boiler can be installed outdoors or in a framework not typically occupied by humans” Scott Nichols said.&nbsp New Hampshire agreed and altered their rules to specify that outdoor boilers are people boilers that are needed to be set up outside, so as not to incorporate indoor boilers that happen to be put in in a garage, for instance. Nichols is urging “all states to adjust their definitions for OWHH as New Hampshire has.”

The EPA’s former voluntary qualification software and current certification program for outside wood boilers (hydronic heaters) has helped to minimize particulate subject when the boilers are operated responsibly.&nbsp In addition to stricter emission standards, most certified boilers now have controls that assist make certain much better combustion through the burn cycle and lessen the impacts of biking.&nbsp

However, a lot of professionals and condition and neighborhood air good quality agencies continue to be involved that EPA-qualified Section two and EPA qualified boilers can make extreme smoke in the hands of many operators.&nbsp One particular key plan reaction has been to set up set backs from house strains and/or nearby residences.&nbsp Most states where outside boilers are well-likedwith the exception of the Excellent Lake states where most outdoor boiler producers are positionedsustain set backs.&nbsp set backs help make certain that outside wood boilers are not installed in densely inhabited regions and even in rural regions, they offer a buffer with the quick neighbors.

Home line established backs: The most frequent sort of established backs are property line established backs.&nbsp They usually assortment from 50 to 200 toes, with a hundred ft becoming the most frequent.&nbsp Maine, Massachusetts, New Hampshire, New York, Pennsylvania, Utah, and British Columbia all use residence line established backs.

Established again from closest neighboring home: Connecticut and Vermont are the only two states that use set again from the closest neighbor’s home.&nbsp They each require 200 toes, symbolizing stricter guidelines.

The two residence line and nearest home: Maine and Massachusetts use the two property line and closest residence. &nbspFor EPA Stage two boilers, Maine needs fifty feet from the residence line or 70 ft from a neighbor’s home. &nbspMassachusetts requires 50 feet from a property line and 75 feet from nearest property.

Seasonal limitations: Two states, Indiana and Massachusetts, do not let outside boilers to work in the summer season as they can result in even far more air pollution in hotter temperature when they are very likely to cycle on and off far more regularly. &nbspIn addition, Maryland just lately wrote draft regulations that would limit use from May 1 to September 30.

Stack heights: Most states that demand set backs also call for minimal stack heights.&nbsp (This memo does not address these.)

Sunset clauses: Most point out guidelines only apply to foreseeable future installations, but some, this kind of as Vermont and British Columbia, have sunset clauses for conventional boilers.&nbsp In British Columbia, only EPA accredited and Phase 2 boilers can be operated soon after November 1, 2026.
