Application filed March 10, 1924. Serial No'. 698,344.

This invention relates to improvements .in means for heating water for hot water supply for domestic purposes. Y y

vThe object of my invention is to provide to what is commonly known as the hot water boilers or tanks, the said device. being of simple, durable and inexpensive constructionL and so arranged and constructed that it may 1o be easily and quickly applied to thel furnace of the ordinary house heating system, w hich may be either steam or hot water or similar system, and when applied the device will very p rapidly and economically heat the water.

More specifically it is the object of my invention to provide.. a heating unit having a comparatively large amount of heating surface and adapted to be placed into a house heating furnace of the ordinary type through the fuel door, the device being so arrangedthat when applied waterl may.

- be made to circulate through'the device and to be heated by the fuel within the furnace.

The device being provided with connections operator.

so arranged that the circulating water from the heater may-be made`to either circulate through an auxiliary water tank or through the house heatingvsystem at the will of the The ldevice is to be preferably y used with that type )of furnaces which employs a liquid fuel burner.

` My invention consists in the construction, arrangement and combination of the various parts of the device, whereby the objects contemplated are attained, aslhereinafter'more fullyset forth, pointed out in my claims,

and illustrated in the accompanying draw-v ings, in which:

Figure 1 is a side elevation of my imroved device showingqthe manner-in -which 1t is connected to a hot water tank, and al@ showing the mannerin which it is'mounted in the heating system, the heater of the said sysFtem being shown in section.

takerlbn the line 2-2 of Fi re 1. c

The numeral 10 indicates the hot water tank of the ordinary construction mounted' on a supporting base 11. The tank 10 is provided with an outlet pipe 12 and an inlet pipe13 which are connected to the water pipe system of a dwelling. The tank 10' 1s also providedwith an inlet circulatmgI p1pe 14' and an outlet circulating pipe 15 which re' 2y is a L horizontal sectional view' are also of the usual construction and arrangement.

- The numeral 16 indicates a hot water heated which may be of any of the ordinary types 1n common use or it may be of the steam or vapor-type. The heater 16 is provided with water compartments 17, a door opening 18 land a fuel burner 19. The burner 19 is prefing room of the dwelling. Burners of this type are usually placed in about the same positionthat thegrates of a coal burning furnace would assume.

' The heater is provided with vthe usual water heating coil 20 which comprises a U- shaped pipe extending .into the re box of the furnace, having one end of the said pipe connected with the inlet pipe 14 of the hot water supply tank, and its opposite end connected with the outlet pipe 15 by means of suitable elbows 21 and laterally extendin pipe portions 22. The coil 2O together wit the pipes 11.1L and 15 are substantially of the ordinary construction. The coil 2O is placed in the fire box in the usual manner and provides means whereby under certain conditions the tank 10 is supplied with hot water y in thesusual manner. J

This arrangement is suicient to give plenty. of hot water under ordinary conditions during the winter months while the heater is being continuously used. To provide ymeans for supplying hot water for laundry purposes and the like during the summer months when the heater 16 is not being used, I have applied an auxiliary water hea-ting element which I have placed manner that the' burner 19 may be em-` ployed to heat the water in the'tank 10.

My improved device comprises a metal casing 23 formed hollow and of such shape and dimensions'as to substantially ll the. fuel door of the furnace. The said casing 23 is provided with a back wall 24, a front wall 25, a top 26, a bottom 27 and end walls 28. Theback 24:.is drilled and tapped with two rows of openings 29 and 30. The openings 2,9 extend near the` top .member 26 and the openings 30 just above the bottom member 27. The openingsh 29 and 30 are designed to receive the ends ,of the pipes 31 which extend horizontally into the furnace re box, and have their inwardly extending ends provided with elbows 32 connected by cation with the water compartments 17.

The T 35 is also provided with an outwardly extending pipe 41 in which is a union 42 .and a cut-off valve'43. The pipe 41` is con-' ,tending into the combustion chamber.

nected to a T 44 included in the pipe 14.

neeatao water for any purpose desired, without the Y expense of an additional burner or controllin mechanism. i

y providing the unions 37', 42, 47 and 51 I have provided means whereby the heating unit may be easily and quickly attached or detached, and may be entirely removed from the furnace during the winter months if desired, or any time when the furnace is continuously operated; or by closing the valves 43, and 48 and leaving the heater attachment in the furnace and openingthe valves 38 and 52, ,I have provided means whereby the water in the member 23 will be brought -into communication with the compartment 17 and a complete water circulation will be established throu h the coils The front wall 25 is also provided with an 6.1,- the hot Water from said coi s being de` p outwardly extending pipe 45 which includes 11i/ered t0 the Compartment 17 and Caused a T 46 a union 47 and a vcut-oif valve 48. tOLeIltel the regular heatihg System.

The union 47 is between the vT 46 and the `This provides an arrangement which is valvel 48. The outer end of the pipe 45 is VeryA desirable even during .the winter connected to a T 494 in the pipe 15.
