Revisiting Ernie’s GARN WHS-2000

On April 5th we revisited GARN® WHS owner Ernie of YouTube fame. We wanted to see how Ernie was doing with his 25 year old unit.

 

Ernie’s GARN® WHS-2000 in 2016

 

Ernie’s WHS-2000 in 2000

  • His unit is now 25 years old with no major problems.
  • His unit burns as well in 2016 as it did in 1991 when it was installed.
  • He has never had creosote.
  • He heats 5,100 sq ft using about 11 cords of marginal quality cordwood per year.
  • He has eliminated the purchase of 50,000 gallons of heating oil (2000 gallons/year).
  • He remains healthy because of his wood cutting efforts.

We asked Ernie (mid-eighties young) if we could return in another 16 years for another update. He agreed. Not much else can be said…….he is a man of his word and we will be back.

The Cost of Oil

It’s December 2014 and the price of oil (and gasoline) has dropped about 40% from $107/barrel to about $61/barrel, within the last 6 months. Why? There are a number of reasons floating about, including:

  • A worldwide drop in gasoline demand due to a lethargic world economy
  • Lower demand due to cars that get better mileage
  • An excess US supply due to North Dakota fracking
  • The Arab states wanting to maintain market share by “squeezing out” the smaller producers, especially those in North America (fracking and tar sands).
  • A US lead attempt to “control” Putin and his nefarious goals by devaluing the Ruble

I’m not sure which is correct, if any? Are you? In my view it would be prudent to conserve the oil for critical uses (such as plastic manufacturing and medical uses) rather than “wasting it” through inefficient transportation or space heating.  Instead there has been a spike in the purchase of trucks and large SUV’s.  And the US still does not have a clearly defined comprehensive energy policy. This is beginning to sound an awful lot like the 70s’ and 80’s. What in the hell has Congress been doing for the last 44 years?

If we have learned anything from the past, this drop in prices will not last. In a year or two the price of oil will spike higher than it was prior to its dive and stay there for the future. Oil reserves are not infinite; they do have a finite life. As my friend and mentor Raymond Plank (Founder of Apache Oil) recently pointed out:  it takes a million years to form a barrel of oil, but only 80 years to grow a tree.  Oil pricing will ebb and flow, low and high forever. Its pricing is very volatile, connected as much with politics as it is with supply and demand.  In my view, oil extracted from tar sands should be considered criminal abuse of our planet.

So the next time you look at a tree consider what it does for you: provides beauty for the eye, scrubs CO2 from the atmosphere, provides shelter for animals, provides lumber for housing and provides fuel for warmth. Such a versatile, beautiful living creation.

GARN Open House Recap (August 2014)

The GARN® team hosted another very successful Open House at its warehouse and test facility in Arden Hills, MN on Saturday August 23, 2014. Attendees got to meet the GARN® team, experience a cordwood test burn of a GARN® 1000, as well as enjoyed lunch and refreshments. As a team, we certainly enjoy meeting our customers, answering their questions and demonstrating the clean, efficient burn for which GARN® equipment is noted.

Green Mountian Technology & Career Center
Hardwick, VT
Black River Design
7,000 Square Feet

The Green Mountain Technology and Career Center in Hardwick, VT is a 7,000 square foot classroom building for students with an interest in forestry and related areas. It contains a large forestry lab, a maple products lab, and two large classrooms, as well as administrative space and tool rooms. The building is extremely well insulated with 6.5″ structural foam panel walls and foam panel roofing with low-e fiberglass windows. Heating is provided by a Garn wood fired storage boiler with an oil/biodiesel fired backup boiler. The Garn boiler consists of a high efficiency firebrick lined combustion chamber surrounded by 1500 gallons of water storage. The boiler is fired with a batch of wood and heat is exchanged from the flue gases into the water storage. After the batch of wood is burned the fire goes out and the stored heat is used to heat the building. The results is a clean burn of the wood without the need to constantly tend the fire and the ability to heat from storage overnight in the most conditions.

Billings Farms Forest Service at Woodstock, VT

 

Billings Farms Forest Cente – Woodstock, VT

 

[box] The Mill Complex Forest Center is a 2000 square foot mini conference center located on the Billings Farm Museum in Woodstock, Vermont. The building is designed to be heated entirely with renewable wood harvested on the site and burned in a Garn storage boiler. The ventilation system incorporates both natural ventilation and an air-handling unit with CO2 demand control to handle variable occupancy. Cooling is provided by an ultra efficient SEER 21 condensing unit. More than half of the electrical energy will be provided by a PV Array. The building as modeled by Carrier HAP V4.34 is projected to use 35% less energy than a code building. The building was awarded a Leed platinum rating in 2009. System design by Kohler & Lewis of Keene, NH.[/box]

THE GARN WOOD HEATING SYSTEM

The GARN® WHS is a simple, efficient, and durable wood heating unit. What we manufacture is a state-of-the-art wood fired hydronic heating system with 30 years of tested technology and experience. Our wood burning boilers use a large hydronic thermal storage tank to store the heat from a fast, clean, and efficient wood burning gasification process. GARN® wood heating systems can burn cord wood, slab wood, pallets and other scrap wood, dense wood briquettes, and air-dried corn on the cob. GARN® hydronic heaters produce virtually no smoke because of their patented, two-stage wood gasification technology. A GARN® is not an outside wood furnace, outside wood boiler or an outside wood stove. The GARN® is installed indoors and provides hot water for heating your home, shop, business, or district heating system. All of our models combine high-efficiency wood combustion and hydronic thermal storage to produce the most efficient and simple wood heating units on the market.
Ask anyone who owns a GARN®. Our simplicity, longevity, and efficiency sets us a world apart from anyone else in the wood burning industry. Click here to see a unit in operation.

 

Fuel oil and propane prices are higher than they’ve ever been. Consider a GARN® wood heating system and save money on next year’s bills.

[learn_more caption=”Easy Integration”] radiant floor, hot water baseboard, cast iron and European style radiators, forced air furnaces, or other heating systems allows the units to be added into existing applications or new construction with ease. [/learn_more]

GARN® units comply with all applicable UL and CSA safety standards, and because of their low exhaust temperatures, are the only wood-fired hydronic heaters certified for both horizontal or vertical flue venting in the United States.
Every GARN® unit ever sold has been 100% manufactured in the USA.
