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 Most point out rules refer to Stage 1 and Stage 2 boilers, a voluntary plan that has now been superseded by certified boilers in new EPA rules.
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.  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.  Most states that regulate outdoor boilers have established set backs, from fifty to a lot more than two hundred feet.
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.  “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.
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.  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.  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.
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.  One particular key plan reaction has been to set up set backs from house strains and/or nearby residences.  Most states where outside boilers are well-liked—with the exception of the Excellent Lake states where most outdoor boiler producers are positioned—sustain set backs.  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.  They usually assortment from 50 to 200 toes, with a hundred ft becoming the most frequent.  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.  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.  For EPA Stage two boilers, Maine needs fifty feet from the residence line or 70 ft from a neighbor’s home.  Massachusetts 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.  In 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.  (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.  In British Columbia, only EPA accredited and Phase 2 boilers can be operated soon after November 1, 2026.

About 2,000 Quadra-Fire Mt. Vernon E2 pellet stoves and inserts are being recalled and repaired, due to high pressure that can lead to explosions that shatter the glass in the door. The company says the stove is safe if properly operated. The Consumer Product Safety Commission issued a voluntary recall on July 9, 2015. Problems were first reported to the company by consumers in the winter of 2015.
The problem is unique to this model and does not present a safety issue in other models sold by Quadrafire or any other manufacturer, according to pellet stove experts. If you own a Mt. Vernon, follow instructions in the voluntary recall notice and the company will repair the stove free of charge.
Some consumers and stove retailers contend that the stove was poorly designed and even if a stove is not operated properly, it should not build up pressures that can lead to explosions. At least 6 stoves have malfunctioned, leading to glass in the front door shattering, sometimes sending flying glass through rooms. No injuries have been reported. AGH believes the EPA should ask that this stove be re-certified since changes to it are substantial.
A number of discussions in independent chat rooms have raised the issues and include commentaries by affected consumers about how Quadra-Fire has responded.
The Alliance wrote to HHT asking for clarifications about what caused the malfunction and whether the stove would be 3rd party tested again for safety. We formally asked for information for our newsletter, which may have led to a less responsive reply, which is reproduced below.

Subject: RE: questions about the Mt Vernon E2 for wood heat newsletter
1. Will HHT be sending this stove back to any 3rd party lab for safety testing?
When a modification is made to a Hearth & Home Technologies product, all necessary certification bodies are informed and the required testing is completed. Updates and notifications are published as necessary, and in accordance with the respective entities.
2. In your certification testing with OMNI, did any of the tests involve running the stove as the consumer might do it, instead of following the owner’s manual?
OMNI follows the testing protocols set forth in the test standard that the appliance is being certified to. The test standards follow ANSI protocol, and go through a revision process that allows for review and comment from interested parties to address future requirements and enhancements for performance and safety.
3. From your website and from talking to various HHT dealers, its confusing as to whether you consider this mainly a problem with incorrect operation by consumers, or whether its a flaw in the stove operating system. Your site says that the stoves in question will receive an enhanced control board “if necessary.” Are there some stoves that are not getting an enhanced control board or do all stoves in the recall get the enhanced control board?
HHT issued this recall proactively and in conjunction with the CPSC to reinforce our commitment to consumer safety. No injuries related to the Mt. Vernon E2 stove or insert have been reported. Issues of glass breakage are only related to Mt. Vernon E2 stoves and inserts when not maintained as outlined in the owner’s manual.
This recall affects an isolated set of units; if the unit is verified to be within the select group of recalled stoves or inserts, the control board should be replaced. HHT dealers have proactively contacted all consumers with affected stoves to have them repaired.
Lastly, you mention being unable to connect with someone at HHT. While I can’t speak to previous relationships, I do want to open the door for you to connect with me when you have questions moving forward. We always appreciate the opportunity to share factual information about our products and/or to share our passion and enthusiasm for the industry, and I can typically turn around responses in 2-3 business days.
