  Website excerpts:
  
  EFM Company History EFM (Electric Furnace Man) is one of the oldest names in heating in the United States. The company logo includes the phrase, “The finest in automatic heat”, which refers to the origins of the company as a manufacturer of coal stoker boilers.
  
  Coal fired heating around the turn of the century was still a dirty and time consuming proposition. A coal stoker invented at e·f·m made it possible to feed coal automatically to the fire and even to change the feed rate in response to a thermostat. This innovation was a great time saver and improved the comfort of millions of Americans. ... The EFM stoker boiler is still made today.

  Excerpts:
  DANGER: This boiler is equipped with a fuse-able plug. It is located inside the boiler. It is not adjustable. In the event that boiler water temperature exceeds approximately 276° F, a dangerous condition, the plug will open and boiler water will fall into the firebox.
  
  Follow all operating instructions carefully to avoid a dangerous condition that would result in activation of the fuse-able plug.
  
  The WCB Hand Fired Boiler is designed for both wood and coal firing. It is provided with a cast iron shaker grate and a firebrick combustion chamber lining with an overhead baffle which provides a double pass for the flue gases for better heat extraction from the fuel being burned.
  
  This boiler is primarily intended to be an “Add-On” unit to an existing oil or gas fired forced hot water boiler.
  
  This boiler is not intended to be the sole source of heat except for the storage buildings, cabins, etc. where constant steady heat is not required.
  
  See instructions under heading “To Set Up Boiler” for proper application. This boiler is not to be used with an automatic stoker.

The EFM ElectricFurnaceMan company, founded in New York as the General Machine Company in 1907, was originally a producer of coal-stoker boilers. EFM was later described as a subsidiary of the General Macine Corporation, in Emmaus, PA.

In 1974 the EFM company's CEO, Frederick Kalmbach ,Jr. was described:

Born and reared in New York City, Fred Kalmbach says that when the General Machine Company, Inc. expanded from New York to Emmaus in 1941 he was very happy to move here along with it.

From 1946 to 1953 he was president of the company and its subsidiary, Electric Furnace Man, Inc. In 1953 he was elected president of the Emmaus Foundry and Machine Co., Inc., a post he held until his retirement in 1968. - "The Probe", Allentown PA, October 1974.

Below: an obituary for Frederick Kalmbach Jr., an Electric Furnace-Man executive, appearing in the November 1981 edition of "The Probe" published by the Allentown PA Hospital.
