Because of lack of time, these appliances were all tested when new, and no allowance was made for depreciation during use, a factor which undoubtedly would be of considerable moment. The heaters used for this test were all of familiar types as described and illustrated: No.i was a heater of the steam or hot water cast iron radiator type, the radiator containing water heated by an atmospheric burner beneath. No. 2 was a heater of the incandescent fuel type, the fuel, PMOTOMETRICAL LABORATORY Fig. i. hollow balls of refractory material, being heated by an atmospheric burner on which they were placed. (This heater was designed for use with natural gas, and satisfactory combustion with low pressure manufactured gas was impossible. With a properly designed burner, a higher efficiency is to be expected.) No. 3 was a heater of the gas log type, the logs being made of refractory material on which was placed a small amount of fiber asbestos. Holes in the logs served as burner orifices, and the refractory material of the logs and the asbestos were heated by these flames. This heater was equipped with an atmospheric burner. No. 4 was a heater of the fire-place type made of a perforated metal back covered with fiber asbestos, the asbestos being heated to a high degree of luminosity by the atmospheric flames from the perforations in the metal back. No. 5 was a heater of the reflecting type, a polished back of copper reflecting the heat of the luminous flames from lava tips in the top of the heater. No. 6 was a heater of the radiator type, the radiator made of sheet iron tubes, with luminous flames from lava tips at the bottom and inside of each tube. the blue flame and...
