Improved Domestic Hot-water Apparatus for Buildings
We JOHN LANT, Masonry Inspector, of ɔɔ Spoor Street, Dunston on-Tyne,
and JOE COOPER, of Ravensworth House, Dunston on-lyne, Gateshead in the
County of Durham, Manufacturer do hereby declare the nature of this invention
to be as follow>
This invention has for its object to prov de the upper stories of a house with
supply of hot water for domestic purposes heated by the kitchen fire in the
basement, without the necessity of employing the usual system of hot wate
Circulation pipes between the basement and the point at which the hot water is to
be supplied
The invention consists mainly in locating the boiler within a flue chamber
formed in the chimney breast on the upper storey at a higher level than the point
at which the hot water is to be diawn off, the flue chamber in which the boiler is
situated being either in connection with the main flue from the kitchen range or
with a separate flue leading from the back or side of the range, this supplementary
flue leading either into the main flue from the kitchen or into the flue of the

apartment, in the chimney bieast of which the boiler is located
suitable dampers would be provided to enable the heating of the boiler to be
brought under control The boiler is surrounded by a flue space on all sides
except one at which a door is provided to give access for cleaning out the boiler
and pipe connections and examining the ball valve controlling the water supply to
the boiler from a main or overhead cistern From the boiler a single pipe leads
with the necessary branches for drawing off hot water at the various points required
either on the same storey as, or on any story below, that at which the boiler is

Improved Domestic Hot-water Apparatus for Buildings
We, JOHN LANT, Masonry Inspector, of 53, Spoor Street, Dunston-on-Tyne,
and JOL COOPER, of Ravensworth House Dunston-on Tyne, Gateshead, in the
County of Durham, Manufacturer, do hereby declare the nature of this invention,
and in what manner the same is to be performed, to be particularly described and
ascertained in and by the following statement
This invention has for its object to provide a hot water service throughout a
house, heated by the kitchen fire in the basement and with draw off points at the
upper as well as the lower stories, without employing the usual system of flow and
return circulation pipes between the basement and the upper storey, the only piping
required being that necessary for conveying the hot water to the various points
011

page_text: where it is required to be drawn off By this means the cost of establishing the
hot water system is greatly reduced
Reference is to be had to the accompanying drawings, forming part of this
Specification, wherein
Figure 1 represents a sectional elevation of a two-storied house provided with
the improved system of hot water apparatus and
Figure 2 is a cross-section of the range fireplace, shewing the hot air inlet
Figure 3 is a sectional elevation, on a larger scale, of the water heating tank
or boiler and the flue chamber in which it is placed
Figures 45, and 6, shew vertical and horizontal sections of modified forms of
boiler which may be used
The invention consists mainly in locating the hot water tank or boilei A within
a flue chamber B formed in the chimney stack of the kitchen flue and situated in
the chimney breast of a room on in upper storey at such a height that the
boiler or tank is located at a higher level than the highest point at which the hot
water is required to be drawn off
In the example shewn in the drawing the hot water is supposed to be supplied
to the bath D, and the sink F, the former being here represented on the
upper storey and the latter on the basement The flue chamber B in which the
hot water tank or boiler A is situated is connected with a flue H leading from
the fireplace G of the kitchen range, preferably from the back thereof, and in
connection with the fluc around the oven, so that the oven will be heated by the
hot air on its way to the boiler, suitable dampers being provided to regulate the
draught through the oven flues as may be required The air inlet to the flue H
is at in the back of the fireplace, so that air heated by being drawn through the
hottest part of the fire will be admitted to the flue H to be conveved to the
boiler The flue H by which the hot air is conveyed to the flue chamber B ot
the boiler A, would generally be formed by piping led up within the main flue I
of the kitchen fire place, as shewn, and through the brickwork of the chimney
breast of the upper chamber, to the boiler flue chamber B
The arrangement shewn is best ad ipted for a house already built, but in building
a new house the flue H might be separately formed in the brickwork of the
chimney breast
The flue chamber B may be connected at top by a short flue H' either with
the main flue I or with the flue J of the apartment in the chimney breast of which
the boiler A 1 located A suitable damper would be provided as at K to
enable the diaught through the flue H to be regulated as required in order to
bring the heating of the boiler under control The boiler A is surrounded by
the flue space of the chamber B on all sides except one, at which a door a
(Figure 3) is provided to give access for cleaning out the boiler and pipe con-
nections and for examining the ball valve b which controls the cold water supply to
the boiler through the pipe c from the main or an overhead cistern From the
boiler A a single pipe d leads, this pipe being provided with the necessary
branches ef for diawing off hot water at various points either on the same storey
as, or on any storey below, that at which the boiler A is situated, the necessary
overflow and steam outlet pipes discharging in any convenient positions being also
provided
Figures 4, and 5, are tubulai boilers, the tubes of the former being straight
and those of the latter curved as shewn and connected with smoke boxes Bat
top and bottom The boiler shewn in Figure 6 has a spiral flue running through
it Either of these boilers would be fed from a tank (not shewn) at a higher
level, such tank being supplied through an ordinary ball cock valve
Having now particularly described and ascertained the nature of the said inven-
tion and in what manner the same is to be performed we declare that what we
claim is
A domestic hot water apparatus wherein the water heating tank or boiler 18

fireplace of the range in the basement so that air heated by being drawn through
the fire will be conveyed to and heat the boiler which is provided with a cold
water feed and with a draw-off pipe leading to the points where hot water is
required to be drawn off, substantially as specified
