4 Claims. (Cl. 122-20) This invention relates generally to heating systems and more particularly to a water heater and boiler booster assembly usable in connection with a conventional heating apparatus, in a manner to effect a marked saving of fuel.
It is well known that a considerable wastage of fuel occurs in almost all conventional furnaces, whether oil, gas or coal fired. This wastage results from the fact that much of the heat goes directly up the ue without being put to advantageous use. In many, instances, a hot water heater has its own flame or electrical heating unit independently of the furnace or boiler so that in such situations fuel is consumed at two separate locations at relatively great expense.
In some heating systems, the furnace may be provided with a hot water heating coil. Even in this situation, however, there is a wastage of fuel, because the hot products of combustion still travel up the ue without being put to eicient use.
The main object of the present invention is to provide a fuel-conserving apparatus in the form of a water heater and boiler booster assembly for association with conventional heating apparatus that is an improvement by reason of its novel structure over similar apparatus previously used for carrying out the same purpose.
Another object of the invention is to provide a domestic water heater and a boiler booster in a single unit.
Still another object is to provide a water heater and boiler booster that is e'lcient and economical and that can be operatively connected with domestic boilers or furnaces and tanks now in use without radical changes in construction or arrangement of the parts thereof.
A specific object of the invention is to provide a water heater and boiler booster unit of the kind described of substantially U-shape so that the hot products of combuston leaving the combustion chamber are given a relatively long travel before they enter the flue in order that they may give up their heat to the water in the unit.
A further object is to so design the apparatus that it can be installed in the various devices with which it is used with maximum ease and speed and without the use of skilled labor.
For further comprehension of the invention, and of the objects and advantages thereof, reference will be had to the following description and accompanying drawings, and to the appended claims in which the various novel features of the invention are more particularly set forth.
In the accompanying drawings forming a material part of this disclosure:
'I'he single figure is a vertical sectional View of a water heater and boiler booster assembly embodying our invention, a portion of the furnace being shown in section.
Referring in detail to the drawing, a water heater and boiler booster unit 14' is shown used with a furnace or boiler and a chimney or stack 40'. The furnace or boiler 10' has the usual water chamber Z2' and a jacket 24' for the hot products of combustion therearound. A water heating coil or pipe 86 is shown conventionally in lee the water chamber 22' of the furnace 10'. The coil or pipe 86 is connected by connected water supply pipes 88 and to a water supply and is connected by a service pipe 92 to a kitchen, bathroom or other place in the house or `apartment where hot water for Washing or other purposes is needed.
The water heater and boiler booster unit 14' includes a U-shaped pipe 26 the upper end of one leg` 28' of which is integrally connected to a horizontally disposed pipe 30 which may be insulated and which leads to the outlet 31 in the jacket 24 at the top of the furnace or boiler whereby heated gases of combustion from the furnace will enter the top of the unit. The flow of gases through the pipe 30' is controlled by a damper 32' operated by a shaft 34'. The upper end of the other leg 36' of the pipe 26 is integrally connected to a horizontally disposed ue pipe 3'8" leading to a chimney or stack 40'.
A single spiral copper water coil 42' is mounted in the passage of the leg 2S of pipe Z6'. The convolutions of the coil are closely spaced and the coil is substantially round in plan to correspond to the cross-sectional contour of the leg 28. The upper end of the coil extends through an opening in the leg 26' by means of an extension 46 and connects with a short pipe 48 by means of a union 52'. Pipe 48' extends through aligned openings in the outer walls and inner walls of the jacket 24 of the furnace 10' to the water chamber 22 of the furnace. A valve 50' is interposed in the short pipe 48' for controlling the flow of water through the coil. The lower end of the coil 42' is similarly connected to the water chamber 22 by means of an extension pipe 54' connected to a short pipe 56 by a union 58. A valve 60" is disposed in the short pipe 56' to control the flow of water through the coil. The coil 42', it will be noted, is directly in the path of movement of thehot gases as shown by the arrows.
A single spiral copper water coil 62 similar to coil 42' is also mounted in the leg 36' of the U-shaped pipe 26', the arrangement and shape of the convolutions being the same as that of coil 42'. 'I'he lower end of coil 62' extends through an opening in the leg 36' by means of an extension pipe 72' and is connected to one end of a water supply pipe 8'8 by means of a union 73'. The upper end of coil 62' extends through an opening in the leg 36' by means of an extension 64' 'and is connected to one end of a water supply pipe 90- by means of a union 68'. Valves 94 and 96 control the ow of water through the water supply pipes 83 and 90, respectively.
In operation, assume that the furnace or boiler 10' is charged with boiler Water as is the coil 42' and coil 62', while the damper 32' is open. It follows that the waste heated gases of combustion from the jacket 24 of the furnace passes through the pipe 30 into the pipe 26', as shown by the arrows, down through the leg 218' of the pipe 26', along the bight portion 82 of the pipe and up through the leg 36'. Heat from the gases passing through the gas passages of leg 28' of pipe 26' is transferred to the water in the coil 42' and thence to the water in the chamber 22' thus boosting the temperature of the furnace or boiler water. At the same time, the heat from the gases passing through leg 36' is transferred to the water in the coil 62' to heat the water as it passes from the cold water supply pipe 90 to the cold water supply pipe 88 and thence to the heating coil '86 and hot Water supply pipe 92.
While we have illustrated and described the preferred embodiment of our invention, it is to be understood that we do not limit ourselves to the precise constructions herein disclosed and that various changes and modifications may be made within the scope of the invention as defined in the appended claims.
