Abstract

339,734. Low & Sons, Ltd., A., and Low, D. W. Oct. 24, 1929. Heating by electricity.-Relates to a water heater comprising a bulk water chamber a, an electrically heated boiling chamber b communicating therewith, and a collecting chamber d provided with a tap f and connected to the boiling chamber by an expansion pipe or passage c. The overflow from the chamber d passes through the pipe g to the top of the bulk chamber, and the boiling chamber inlet g<1> is fed from the bottom, and top of the bulk chamber by pipes h<2>, h<1> respectively. The bulk chamber is fed from a float-controlled cistern through the pipe a<2>. The outlet of the pipe a<2> to the bulk chamber and the inlet of the pipe h<2> are controlled by normally balanced galves i<1>, i carried on a pivoted arm. When water is drawn from the boiling chamber cold water flowing through the pipe a<2> tilts the arm to close the valve i so that the boiling chamber is fed only by hot water from the top of the bulk chamber. The boiling and collecting chambers are surrounded by a jacket e' containing air or heat-insulating material. A cover l for reflecting the water into the boiling chamber is provided. The switches and supply terminals are arranged in the box o. The heating elements j are removable.
