Our Furnace
Believe it or not, our entire little house in Maine is heated by 2 of these Monitor heaters for less than $1000 a year in kerosene. The upper picture is a print of the Cape Elizabeth light house that we had in New Jersey before we even decided to move to Maine, and the lower one is a print of sledding in Central Park in New York City, just so we don't forget that that was fun, too. The ivy in the basket has been there for about 5 years, and the Hoya on the left is out of control but refuses to brloom. Behind it you can see the bay window which has Jasmine growing up both sides of it. Sometimes it blooms, and it needs a trellis across the top because it is also out of control and threatening to take down the curtains.
