This is an apt painting to post after spending the last three days with a non-functioning furnace. My indoor temperature has hovered between 51 and 54 F...(last night it was -3C outside)...I can't do the math. After almost $900 (!!!) my furnace has a new blower, and I have heat. I'm sure I will feel that it was worth it after my stomach settles down. The 'plus' side is that I have a small home studio which it is the only room equipped with electric baseboard heaters, and it has gotten a lot of tidying in the past two days!
