PERIODICAL ROOM The litera Digest (Title Reg U.S. Pat. Off.) THE LIGHTHOUSE KEEPER'S DAUGHTER-By Norman Rockwell New York FUNK & WAGNALLS COMPANY London PUBLIC OPINION New York combined with The LITERARY DIGEST Vol. 78, No. 4. Whole No. 1736 July 28 1023 Price to Conte "We'll never quarrel about HEAT," chuckled the landlord, "You control that yourselves H EAT has always been the chief cause of dissatisfaction among apartment house dwellers. No two families want their apartments the same temperature; yet, ordinarily, they are forced to accept whatever heat the janitor or superintendent of the building thinks they should have. No wonder they are quick to appreciate the unique merits of Hoffman "Controlled Heat." In a building equipped with this new heat, each tenant can easily and accurately regulate the temperature of his own apartment to suit himself. Simply a touch of the finger on the control valve, which is on each radiator, gives the exact heat that is wanted, when and where it is wanted. Each tenant is literally "boss of his own heat." From the standpoint of the building owners, "Controlled Heat" is equally desirable. It is by far the most economical heat that can be used in an NEW YORK apartment building. In the first place it is vapor-heat operating on surprisingly low pressure, which means fuel economy. Then, the great waste that comes from unwanted heat is entirely eliminated. For "Controlled Heat" generates heat only as it is required. Whenever a radiatorcontrol-valve is regulated by a tenant it immediately affects sensitive regulators in the boiler-room which accelerate or retard the flow of steam to meet the change. No more heat is generated than is wanted. An immense saving in coal! Wherever "Controlled Heat" is in operation, in homes or in large buildings, it is setting new standards of heating comfort, economy and efficiency. We shall be glad to answer inquiries from those planning to build. The coupon at the right will bring you an interesting booklet which explains Hoffman "Controlled Heat" in greater detail.
