How was the house heated and illuminated?
The house was heated primarily by fireplaces (at the rate of about ten cords of wood per month). From 1795 Jefferson used wood-burning stoves both open and closed) in certain rooms. In the late 1790s he altered the dimensions of his fireplaces to apply the fuel-saving principles of Count Rumford. Candles provided most of the illumination, although Jefferson owned a number of oil-burning lamps as well.
