I heat a 22 by 22 foot cabin with a half 2nd floor and dormer with a
72, 000 BTU Toyo Laser 73.
The cabin has 3 inches of sprayed foam in the walls and 5 inches in a
cathedral roof that is on a 12 x 12 pitch. When it is 55 F below zero
outside it runs on high all the time, and we sometimes add a 1500 watt
electric heater. The Toyo stove has a great reputation in Alaska as
being very efficient, but they have to use No. 1 fuel oil and cost
about $1700. They last and last and do not require a flu, just a
little 2 inch hole through the wall. The reason they are so efficient
is because they suck combustion air in through a pipe around the
exhaust pipe so the combustion air is preheated. But I am putting in
a coal stove this summer, because No.1 diesel is now about $4.50 a
gallon and goes up about 50 cents every two months. We burn about 90
gallons a month in the winter. No one here can afford electric heat,
because it too has risen in price and probably will continue to
increase. Coal is the answer. It seems we are going back 60 years in
time because of the state of the economy. Incidentally, all the
stores around here are out of rice and they say flour is next.
