Abstract

977,672. Hot-water boilers. JOHN WHITEHOUSE & SONS Ltd., and R. J. WHITEHOUSE. Nov. 19, 1963 [Nov. 21, 1962], No. 43987/62. Heading F4A. [Also in Divisions G1 and G3] A hot water boiler comprises a hot water cylinder 12 heated by a coil 15 having inlet and outlet pipes 16, 17, which are also connected to an expansion or vent pipe 18 and a downpipe 19 from an expansion tank 14. A cold water tank 13 supplies the cylinder 12 and also supplies the expansion tank under the control of a liquid level device 20 (see Division G1).
