“Remote, centralized electricity production and its related transmission are substantially much more vulnerable to significant electrical shutdowns from earthquakes, hurricanes, fires, wind, ice, human error, cyber assault or terrorism than distributed era.
On May nine, 2013, the Alliance for Eco-friendly Heat and the Biomass Thermal Vitality Council (BTEC) co-hosted a webinar with the EPA on how the new wood heater New Source Performance Requirements (NSPS), which may be promulgated as early as 2014, may encourage or discourage innovation in wooden and pellet stoves and boilers. The EPA’s Gil Wooden, Undertaking Lead of the NSPS, offered an explanation of the new wooden heater NSPS and answered attendee concerns that experienced been asked for in advance.
This webinar was  held in the guide up to the Wooden Stove Layout Challenge, a countrywide competitiveness to promote extremely clean, effective, innovative and affordable cordwood technological innovation. The total recording is under and the slides are available for viewing below.
Introduction: :00 – seven:54.
Presentation by Gil Wood: seven:fifty four – forty six:33.
Q&A Session: forty six:33 – 1:33:00.
A lot more stove makers are submitting third party confirmed efficiency figures on the EPA’s list of accredited wooden and pellet stoves, providing these shoppers who really treatment about confirmed effectiveness quantities a lot more possibilities. Even so, there are nevertheless only five firms who submit the confirmed performance of at least one of their stoves:          Blaze King, Kuma, Jotul, Travis and Woodstock Soapstone.
The Alliance cautions customers from relying on stove efficiency promises posted on producers web sites. Most makers submit efficiencies quantities employing a variety of non-standardized calculations. Almost all post efficiencies employing the European reduced heating worth (LHV) standard, which was used by Congress and the IRS for the federal wood and pellet stove tax credit score, as opposed to the increased heating worth (HHV) normal utilized by the EPA. See this Wikipedia page for far more about the variation among LHV and HHV.
The EPA has never ever required stoves to be examined for effectiveness but strategies to do so in the following 18 – 24 months.  Once that occurs, shoppers will be capable to make far more informed alternatives.
Examined efficiencies of wooden stoves are much less crucial than pellet stoves, simply because effectiveness is greatly dependent on the dampness articles of your wooden and how nicely you operate your stove. With pellet stoves, the lab examined effectiveness numbers are much more representative of efficiencies you are likely to get at property (though pellet stoves that do not have ash cleaned and regular maintenance and yearly comprehensive cleanings will get rid of efficiency.)
Wood Stoves with Verified Efficiencies
There are now three manufacturers putting up verified efficiency numbers on the EPA record for non-catalytic stoves and a few for catalytic stoves. Amongst the non-cat stoves, Blaze King’s Scirrocco and Ashford are 75% successful, Kuma’s Tamarack is seventy three%, Blaze King’s Briarwood is 71% and the Jotul F602 is 70%. These are all HHV figures and significantly over the 63% HHV default performance price for non-cat stoves on the EPA record. (These verified efficiencies, ranging from 70 -seventy five% HHV, would be roughly seventy seven-83% LHV and as a result all easily qualify for the federal tax credit.)
There are also three producers publishing effectiveness quantities for their catalytic stoves. Blaze King has five designs among 77 and eighty two% effectiveness. Woodstock as a single model at eighty one% and Travis has two, each at eighty%.  Of all the wooden stove companies that checklist 3rd-social gathering, verified efficiencies on the EPA list, Blaze King is the only organization that lists verified efficiencies for all their stoves.  The others only record it for one particular or two versions.
Pellet Stove with Verified Efficiencies
As of March 2013, there is only one particular pellet stove firm with a verified effectiveness on the EPA checklist – Seraph Industries.  Unfortunately, the EPA mistakenly listed their LHV amount and recurring ask for by the Alliance for Environmentally friendly Heat has not resulted in a correction.  The Illinois dependent firm, Seraph Industries, experienced their stoves qualified after screening by Intertek labs, which confirmed 77% HHV performance.  It is essential to be aware that even although the Seraph Genesis stoves at seventy seven% are considerably less than the seventy eight% EPA default effectiveness for pellet stoves, they are probably amongst the most efficient US manufactured pellet stoves.  The regular effectiveness of US made pellet stoves is almost certainly about 70% HHV, based mostly on many 3rd party research.
Seraph’s site does not help to decrease the confusion.  Like almost all stove producers, they only list their LHV effectiveness and do not tell buyers that they figures are LHV, not HHV, or that their inclusion on the EPA list erroneously uses the LHV quantity.
Pellet stoves have considerably wider variability in effectiveness than cat or non-cat wooden stoves, and some shoppers are inadvertently getting versions that are below sixty% or even 50% successful regardless of higher promises by manufactures.
Suggestions for Shoppers
For now, the safest point for shoppers who want higher efficiency pellet stoves is to get stoves that are EPA accredited or are manufactured in Europe. A broad assortment of benefit and large-stop pellet stoves are EPA qualified from companies these kinds of as Harman, US Stove, Englander,  Lennox and Seraph.  EPA accredited stoves have a tendency to be much more efficient because uncertified ones can have extra air in the combustion chamber that can dramatically reduce efficiency.
The typical effectiveness of a catalytic stove on the EPA record is 80% HHV, in contrast to seventy two% HHV for a non-catalytic stove. The regular pellet stove is believed to be only all around 68% HHV productive. The regular particulate emissions for a stove on the EPA listing is one.6 grams per hour for a cat and three.three grams for every hour for a non-cat. Decrease grams of particulates per hour can imply increased performance, but there is not always a immediate correlation.
The Alliance for Environmentally friendly Warmth commends these companies for submitting confirmed HHV effectiveness figures to the EPA so consumers have access to dependable performance info. The Alliance urges shoppers to take into account acquiring stoves from companies who are clear and offer confirmed effectiveness info to the community.

The Board of Directors of the Alliance for Green Heat is seeking nominations for added Board members who can assist increase money, hook up with key constituency groups and offer assistance to the group. The Alliance for Green Warmth was launched in 2009 as an independent 501c3 non-revenue business advertising cleaner and a lot more efficient residential wooden and pellet heating. The Alliance focuses on the passions of consumers, low-earnings populations and communities that expertise higher stages of wooden smoke. Our 2013 flagship system is the Wood Stove Layout Problem, a technological innovation competitors modeled soon after the DOE’s Photo voltaic Decathlon that encourages, showcases and exams modern technologies that may guide to cleaner and more productive wooden heating.
The Alliance has a budget of $ a hundred and seventy,000 in 2013, a complete-time employees of two and a five member Board. Nominations ought to include a brief assertion about the candidate’s qualifications and despatched to email@example.com by Friday, June 28.
