A house heated to 80 degrees will require about 15 per cent more fuel than is needed at 70 degrees. The first step in saving fuel is to avoid letting the fire burn so rapidly that it must be allowed to die down to reduce the heat. For hand-fired furnaces, keep a full bed of coal and regulate burning by means of the drafts. Keep the temperature of the house as near 70 degrees as possible during the day. There is a general practice of letting the fire burn very low at night and forcing it in the morning. A better plan is to reduce the fire slightly during the night, so that the house does not become chilled. When a room is thoroughly chilled, it requires a great deal of heat to make it comfortable again. Heat must be absorbed by the walls and ceiling before the air is warmed. Most people like to sleep with a window open, and this can be a source of considerable loss of heat unless the radiators in that room are turned off and the door shut, to prevent chilling the rest of the house. |
