A cord of freshly cut hardwood from a northern forest (green firewood) contains about 24,000,000 British Thermal Units (Btus) and weighs about 4,500 pounds. After proper air drying, the same cord weighs only 3,500 pounds. The loss of 1,000 pounds of water at 8.34 pounds per gallon is about 120 gallons. The next time you […]
Using wood for heating is not only smart carbon policy, but should also become an essential component of pro-forestation land management. Some believe the countdown timer on a 10 year planetary climate time bomb has begun. They believe we have ten years to figure out how to clip the carbon “wires” or human-induced carbon emissions […]
What is a “Modern Wood Boiler”? Modern wood boilers use sensors, such as oxygen sensors like those found in modern automobile engines, to provide real-time combustion adjustment with separate primary and secondary air controls. Sometimes these boilers are called “lambda controlled wood boilers”. Modern wood boilers almost always use induced draft fans rather than forced […]
Froling has received EPA approvals for PE1 20 and PE1 35 pellet boilers. Results will soon be posted on the EPA Hydronic Heaters List, which can be found here: https://www.epa.gov/residential-wood-heaters/fact-sheet-summary-requirements-wood-fired-hydronic-heaters The PE1 20 has an emission rate of .049 lbs/mmBtu/hr. and an annualized emission rate of .425 grams/hr. Annualized efficiency is 78%. The PE1 35 […]
Some say that burning wood makes more carbon dioxide than burning coal. They’ve either got an agenda or lack the knowledge to make a more nuanced statement. It is a shock statement poorly applied to wood fuel for heating. Those who favor using wood fuel rebut that carbon dioxide output compared to coal is a […]
