Common Brick Serves As Wick in Furnace Vapor Pan
IF THE design of the vapor pan in a hot air or “pipeless” furnace will permit, place a common porous building brick in the water container so that it stands upright inside the furnace jacket. There may not be sufficient room for the brick to stand straight; then it can be tilted at an angle toward the furnace, and, indeed, it seems to furnish more moisture in that position than when perfectly upright. The brick acts as a wick. My experience has been that its use results^ in nearly twice as much water as usual being evaporated, provided the water pan is filled every day.—S. PARKINSON.
