TIOF EVENINSG “STAR; WASHINGTON, "D. C.. TUESDAY. JUNE 2, '1925. = —— — = — ill the oil burner industry be revolutionized? EVERY SUMMER the same thing happens in the oil burner industry. One or two dozen new oil burners appear on the market. Each : nnounces that the industry is to be complcely “revolutionized.” This continues till October 1st. Then with the beginning of cold weather it is found that the same oil burner that delivered good service the winter before is again the one that delivers heat. Of 347 “revolutionary” oil burners that have come on the market in the last 7 years, only 3 or 4 are today fac- tors in the industry. B IL BURNING in the home has been revolutionized but once—7 years ago by Nokol. The success of automatic oil heating for the home dates from the day when the first Nokol with its combustion chamber was installed. That combustion chamber, patented and exclusive with No- kol, is the only known means of producing instantaneously the 1600° of heat necessary for the proper combustion of oil. It allows no part of the flame to touch the boiler. An oil flame must not touch the boiler, which never reaches a much higher temperature than 212° (the boiling point of water). It must touch no cool surface. If it does, the result is soot, boiler insulation, and high oil consumption. / IN THE 7 YEARS since the first Nokol was installed, no principle of oil burning has been discovered that has Special limited offer bettered Nokol performance. The leader- ship of Nokol has never been challenged. Of approximately 75,000 automatic oil burners installed in the United States by 347 manufacturers, 22,000 are Nokols. The fuel cost of Nokol is less than that of hard coal. It is also to the best of our knowledge less than that of any other oil burner, re- gardless of the grade of fuel used. e REAT PROGRESS has been made in oil burning since the first No- kol was installed. This is the quiet steady progress of Nokol itself, progress which has kept it at the head of the industry. Nokol is today the simplest oil burner on the mar- ket. Refinements in the mechanism have been such that Nokol today gives guarantees of performance and efficiency approached by no other home-heating device—coal or oil. Nokol is today able, because of its effi- ciency, to use a higher and more desirable grade of fuel at lower cost. It does not find it necessary to burn fuel oil. It burns a cheap distillate which will always be plentiful. S IN THESE 7 YEARS an organi- zation has been built up capable of prop- erly installing, servicing and guaranteeing Nokol. For every oil burner installation is an engineering problem, as is the installa- tion of a heating plant. One size burner cannot be made to fit all heating plants. The peculiarities of each heating plant must be taken into consideration. One price burner will not fit all homes. The price of Nokol for the smallest jobs is lower than that of any other automatic oil burner on the market. For a larger job the price is propor- tionate. An organization with a thorough knowledge of heating problems cannot be built up in a day or even in a year or two. o5 4 F THERE ARE any very radical improvements made in the oil burner industry during coming years, they will be made slowly, by a burner with the proper experience and the proper organization. They will not be theoretical changes, but changes based on experience in the field. They will not be achieved merely by making hectic promises that neither Nokol nor any other oil burner could fulfill. It is most rea- sonable to expect that they will be made by the oil burner that built oil burning—by Nokol. S TO MAKE CERTAIN you will have your Nokol by fall, act now. More Nokols are being installed this year than ever before. We can install only a limited number by October 1st. Installation dates for September are practically full. Dates for August are rapidly filling. Act now while an installation can still be arranged for at your convenience. Call or phone today for one of our heating engineers. He can tell you after an inspection of your heating plant what a Nokol installed in your home will cost. A limited number of installations are still available on our special of- fer. Attractive discounts for installation now with payments to begin later. Hundreds of home owners have already taken advantage of this offer. You can save money by bringing or sending in the coupon today. AUTOMATIC HEATING CORPORATION 1719 Conn. Ave. N.W. : Phone N. 627 Automatic Oil Heating for Homes Tested and Listed as Standard by the Underwriters’ Laboratories Manufactured and Guaranteed by AMERICAN NOKOL COMPANY, Chicago To sterilize a pin do not put it in the flame. If you do it becomes sooty. Hold the pin close to the lower part of the flame, and it gets red hot without soot. It is heated by radiant heat, which is quicker and cleaner. The success of automatic oil heat- ing for the home dates from the day the Nokol combustion cham- ber was perfected. It is radically different from any other method of burning oil. It meant a com- plete reversal of previous oil burn- ing practice. It is fully patented and exclusive with Nokol. This combustion chamber con- fines in a very small space a very large flame. It reaches the 1600° necessary for the proper combus- tion of oil in 30 seconds. To do the same thing with a refractory brick lining in the boiler requires 20 to 40 minutes. With an open flame burner this temperature is in many cases never reached. An oil flame must not be allowed to touch the boiler or any cool sur- face at any point. To do so causes soot, which represents a definite loss of fuel, besides insulating the boiler. An oil flame allowed to come in contact with the boiler surface also ultimately injures the boiler plates. The Nokol flame does not touch any boiler surface —it acts entirely by radiant heat. The combustion chamber of Nokol produces an odorless, soot- less,smokeless flame. Its high com- bustion efficiency is responsible for the low operating cost of Nokol. It enables us to use the grade of fuel necessary and most desirable for automatic heating service, at the lowest fuel cost. Don’t Wait—Act NOW!
