The Castleton wood stove.

HearthStone’s TruHybrid Technology Paves the Way for the Future of Wood Heating

Tuesday, December 4, 2018

The HearthStone brand, with its manufacturing facility in Morrisville, Vermont, has been working diligently to be at the forefront of clean-burning, solid-fuel technology for over 40 years. HearthStone always works toward its Green Energy Promise: to deliver sustainable, locally-sourced, green-heating solutions.

With new EPA regulations coming into effect mid-2020, the engineering team at HearthStone has developed what has proven to be an uber-efficient, ultra-low emissions combustion system – the TruHybrid. This system combines current primary and secondary clean-burning technology with a tertiary catalytic combustor.

In November 2018, HearthStone’s Castleton TruHybrid wood stove (EPA Certified at 0.69g/hr) was on demonstration in Washington, D.C., at the Wood Stove Design Challenge. During this event, the Castleton proved in a “real world” setting the success of the TruHybrid system that was originally certified by Hearth Lab Solutions, emitting 1.18 grams of particulates per hour on cordwood.

HearthStone currently has four wood-burning units on the VT Wood Stove Change Out list that qualify for an $800 incentive. These units all have a particulate rating of 2.0 grams per hour or less, and have an efficiency of over 70%. This Change Out program is offered to help offset the costs of replacing older and less efficient wood-burning stoves.

On Wednesday, Dec. 5, 2018, Vermont Gov. Phil Scott will visit HearthStone with a contingent of individuals from the Agency of Natural Resources, Department of Environmental Conservation, Forest, Parks and Recreation Department, and the Vermont Public Service Department. They will be discussing the current Wood Stove Change Out program as well as learning more about the new clean-burning technologies HearthStone is developing for the next generation.
