4 Claims.

This invention relates to electric heaters and has for an object to provide apparatus including an electric water heater, a hot water radiator, a fan for disbursing heated air from the radiator throughout the space to be heated, and a sealed tank for separating steam vapor from the circulating water and permitting the vapor to escape into the atmosphere.

A further object is to provide a device of this character which will be formed of a few strong simple and durable parts, which will be inexpensive to manufacture, and which will not easily get out of order.

With the above and other objects in view the invention consists of certain novel details of construction and combinations of parts hereinafter fully described and claimed, it being understood that various modifications may be resorted to within the scope of the appended claims without departing from the spirit or sacrificing any of the advantages of the invention.

In the accompanying drawing forming part of this specification,

Figure 1 is a front elevation of an electrically operated hot water heating system constructed in accordance with the invention.

Figure 2 is a longitudinal sectional view of the electric water heater.

Figure 3 is an enlarged cross sectional view taken on the line 3-3 of Figure 2.

Figure 4 is a fragmentary longitudinal sectional view showing a modified form of electric water heater.

Figure 5 is a sectional view of a combined water expansion and feed water supply tank.

Referring now to the drawing in which like characters of reference designate similar parts in the various views, l0 designates a hot water radiator, the same comprising a casing II which houses upper and lower water receptacles l2 and I3 which are connected by a plurality of pipes M. A plug cap l5 closes an opening in the top of an upper water receptacle and through this opening air may be vented from the radiator when the system is being filled.

An electric motor I6 is mounted in any preferred manner adjacent to the hot water radiator. The motor drives heated air from the hot water radiator throughout the space to be heated such as a room or other chamber.

An electric water heater I1 is provided for heating water or other liquid with which the radiator is supplied. The heater comprises a casing 18 which houses upper and lower water headers I9 and 20 which are connected by a plu- 1937, Serial No. 161,851

rality of pipes 2| preferably formed of glass and upon these pipes electric heating coils 22 are sleeved as best shown in Figure 2.

However, the glass pipes may be dispensed with and metal pipes 24 may be used, as illustrated in it Figure 4, and these pipes are insulated as shown at 25. In this embodiment of the invention the heating coils 26 are sleeved upon the pipes and are insulated.

The upper header IQ of the heater is in communication with the upper water receptacle I2 of the radiator through a pipe 21. The lower water receptacle l3 of the radiator is in communication with a sealed tank 28 through a pipe 29. The sealed tank is in communication with the lower water header of the heater through a pipe having a pet cock 3| by means of which the heater may be drained when necessary. The sealed tank is located above the water header 20 of the heater and is in horizontal alignment 20 with the lower water receptacle l3 of the radiator.

The sealed tank functions to separate steam vapor from the water flowing through the pipe 29 and pipe 30 into the bottom of the heater. The steam rises through a pipe 32 which enters the bottom of an expansion tank 33 having a removable cover 34 which permits of filling the system with water. A steam pipe 35 enters the expansion tank above the water level therein and overlies the hot water heater. The end of the pipe is equipped with a downwardly extending nozzle 36 which is in the path of travel from the fan so that the steam will be blown out into the room to humidify the room.

In some instances it is desirable that the expansion tank be equipped with a feed water pipe 37, as best shown in Figure 5 for replenishing the water in the system when necessary. The 0 pipe is equipped with a float controlled valve 38 which automatically opens to restore the water level in the tank 39.

While the apparatus above described may be used effectively as a heating system the apparatus may also be used to separate soluble gas from a liquid or separate one liquid from another, such as the ammonia type refrigerator where ammonia gas is separated from water by heat.

The electric water heater constructed as above described may be installed in the water system of a dwelling to heat water for the purpose of supplying hot water from the water system.

From the above description it is thought that the construction and operation of the invention will be fully understood without further explanation.

What is claimed is:

1. Heating apparatus comprising an electric water heater, a hot water radiator, flow and return pipes connecting the heater with the radiator, a fan adjacent the radiator for distributing heated air from the radiator throughout the space to be heated, a sealed tank connected in the return pipe from the radiator to the heater adapted to separate steam vapor from circulating Water and permit the steam to escape to the atmosphere, and a pipe connected to the sealed tank and opening into the draft produced by the fan for humidifying the hot air delivered by the fan.

2. Heating apparatus comprising an electric water heater, a hot water radiator, a pipe connecting the top of the heater with the top of the radiator, a fan directing its air blast upon the radiator, a sealed tank for separating steam from return water, a pipe connecting the bottom of the radiator with said tank, said tank being disposed above the bottom of the heater and in horizontal alignment with the bottom of the radiator, a pipe connecting said tank with the bottom of the heater, a combined filling and steam pipe eX- tending from said tank, an expansion tank connected to the last named pipe, and a steam escape pipe connected to the expansion tank above the water level of the expansion tank and opening into the draft produced by the fan.

3. Heating apparatus comprising an electric water heater, a hot water radiator, flow and return pipes connecting the heater with the radiator, a fan adjacent the radiator for distributing heated air from the radiator throughout the space to be heated, a sealed tank in the return pipe from the radiator to the heater adapted to separate steam vapor from circulating water, an expansion and filling tank connected to said sealed tank and a pipe connected with said filling tank opening into the draft produced from the fan for permitting steam to escape into the space to be heated and be distributed by the fan for humidifying the space to be heated.

4. Heating apparatus comprising an electric heater having upper and lower water headers connected by a plurality of pipes, heating coils sleeved on the pipes, a radiator having upper and lower water receptacles connected by a plurality of pipes, a pipe connecting the top header of the heater with the top water receptacle of the radiator, a pipe connecting the bottom water header 1 of the heater with the bottom water receptacle of the radiator, a sealed tank in the last named pipe disposed above the bottom Water header of the heater and in substantially horizontal alignment with the lower water receptacle of the radiator adapted to separate steam vapor from water, a pipe connected to said tank and terminating adjacent to said radiator for permitting steam to escape into the atmosphere, and a fan adjacent the radiator disposed to produce a draft upon the radiator and the pipe for distributing heated air and steam vapor from the radiator and pipe respectively to the space to be heated.
