Heat Loss
#1

What is the easiest way to find out where heat is escaping (or cold air entering) a room in our house?

Close all windows doors, chimney flues, turn on all exhaust fans, ie. range hood, bathroom fans to create a negative pressure in the house. Use smoke sticks holding them near windows, doors, electrical outlets, utilities penetrating the walls, rim joists. Any air leakage will be evident.
