Description

BACKGROUND

The need for heated fluids, and in particular heated water, has long been recognized. Conventionally, water has been heated by heating elements, either electrically or with gas burners, while stored in a tank or reservoir. While effective, energy efficiency and water conservation using a storage tank alone can be poor. As an example, water that is stored in a hot water storage tank is maintained at a desired temperature at all times. Thus, unless the storage tank is well insulated, heat loss through radiation can occur, requiring additional input of energy to maintain the desired temperature. In effect, continual heating of the stored water in the storage tank is required.

Many of the problems with traditional hot water storage tanks have been overcome by the use of tankless water heaters. With the tankless water heater, incoming ground water passes through a component generally known as a heat exchanger and is instantaneously heated by heating elements (or gas burner) within the heat exchanger until the temperature of the water leaving the heat exchanger matches a desired temperature set by a user of the system. With such systems the heat exchanger is typically heated by a large current flow (or Gas/BTU input) which is regulated by an electronic control system. The electronic control system also typically includes a temperature selection device, such as a thermostat, by which the user of the system can select the desired temperature of the water being output from the heat exchanger.

Tankless water heaters are often installed in existing plumbing networks that utilize a water storage tank. Tankless water heaters are often retrofitted to water storage tanks to take advantage of the efficiency of a tankless water heater, while being minimally invasive into the structure of the existing plumbing network. A user who installs a tankless water heater may use a water heater rack to mount a tankless water heater near a water storage tank. Many plumbing networks are built in an environment that is designed to house a full water heater rack, which makes retrofitting a water heater rack possible. But, some plumbing networks are built in an environment that is not large enough to house a water heater rack conveniently if at all. In such applications, it may be beneficial to mount a tankless water heater directly to an existing water storage tank.

DETAILED DESCRIPTION

It should be understood at the outset that although illustrative implementations of one or more embodiments are illustrated below, the disclosed systems and methods may be implemented using any number of techniques, whether currently known or in existence. Like numbers represent like parts throughout the various figures, the description of which is not repeated for each figure. The disclosure should in no way be limited to the illustrative implementations, drawings, and techniques illustrated below, but may be modified within the scope of the appended claims along with their full scope of equivalents. Use of the phrase “and/or” indicates that any one or any combination of a list of options can be used. For example, “A, B, and/or C” means “A”, or “B”, or “C”, or “A and B”, or “A and C”, or “B and C”, or “A and B and C”.

An offset mounting bracket that comprises a primary member and a stabilization member can be used to mount multiple heat engines to a water storage tank. Such heat engines can be tankless water heaters for example. Tankless water heaters are often used in pairs to promote efficient and continuous water circulation. The size of an average tankless water heater may often be too large to mount more than one on a water storage tank directly. Tankless water heaters, which are stacked vertically and parallel the longitudinal axis of the water storage tank, are often too tall to fit on a standard water storage tank.

The ability to mount a tankless water heater to a water storage tank can be beneficial in a water heating system that requires retrofit of a tankless water heater into a piping network that contains a hot water storage tank. An offset mounting bracket can be especially beneficial in situations where space around the hot water storage tank is limited and the hot water storage tank is not tall enough to accommodate directly mounting multiple tankless water heaters to the water storage tank. As such, a top connection bracket of a tankless water heater may extend above a top of the water storage tank. The offset mounting bracket may allow a user to mount a bottom bracket of the tankless water heater directly to the hot water storage tank and a top connection bracket of the tankless water heater to the mounting bracket. The mounting bracket may be mounted to one or more surfaces on the water storage tank, such as the top and sidewall surfaces. This provides a structure to support the tankless water heaters while taking minimal space in addition to the water storage tank. Such an offset mounting bracket can make it possible to accommodate retrofitting existing plumbing network applications that have significant space constraints.

When compared with a traditional water heater and water storage tank system, the above features provide for a larger capacity hot water system with redundant heating engines in a smaller footprint and overall volume of space than conventional redundant high capacity water heating systems. For example, an implementation of the hot water supply system can include a 119-gallon intelligent hot water storage system with a 15 GPM recirculation pump. The hot water supply system can include a water heating engine system with two tankless water heaters with an input less than 200,000 BTU/hr. In some implementations, the input is greater than 190,000 BTU/hr. In this exemplary implementation, the hot water system occupies a square footage of less than 16.38 square feet and a total system volume of less than 103.9 cubic feet. For example, the hot water supply system occupies a square footage of about 11.13 square feet and a total system volume of about 64.5 cubic feet. Accordingly, the hot water supply system provides for increased capacity while providing redundant heating engines in a smaller floor space than conventional systems.

FIG. 1 illustrates an offset mounting bracket 100, which includes a primary member 102, a stabilization member 104 and a connecting member 106. The mounting bracket 100 may have a rigid body where each member is rigidly connected to at least one other member. Each member may be connected to the others by welding or fastening. The primary member 102 has a top surface 102a, a bottom surface 102b, an inner surface 102c, and an outer surface 102d. The inner surface 102c and the outer surface 102d extend between the top surface 102a and the bottom surface 102b. In some implementations, the primary member 102 can have at least one fastening hole, which may pass through the inner surface 102c and the outer surface 102d (shown in FIG. 3). A heat engine such as a tankless water heater, can be fastened to the primary member using a fastener such as a bolt, a rivet, or a weld. In some implementations that include a bolt, the bolt can be inserted through the at least one fastening hole. The primary member provides an interface to connect a heat engine and can be the primary connection point for mounting a heat engine. The primary member can also be a central structural support for the offset mounting bracket 100.

The stabilization member 104, has a top surface 104a a bottom surface 104b, a supporting surface 104c that is opposed and connected to the primary member outer surface 102d, and a non-supporting surface 104d. The supporting surface 104c and the non-supporting surface 104d extend between the top surface 104a and the bottom surface 104b. The bottom surface 104b of the stabilization member 104 can be offset from the bottom surface 102b of the primary member 102 in a direction that is disposed away from the primary member 102 top surface 102a. The stabilization member 104 can be configured to rest against a cylindrical wall of a water storage tank (shown in FIG. 2). The supporting surface 104d can face and rest against a parallel surface, to support the structure of the offset mounting bracket 100. For example, the stabilization member 104 can rest against the cylindrical wall of the water storage tank (shown in FIG. 2). The stabilization member 104 can support the weight of the offset mounting bracket 100 and any object that is attached thereto, such as a heat engine. The stabilization member 104 can be configured such that the structure of a water storage tank, can exert a normal force against the supporting surface 104c and stabilize the offset mounting bracket 100 against any rotational force caused by the weight of an attached object.

The connecting member 106, has a connection surface 106a, a top surface 106b, a radial surface 106c, and an inner surface 106d. The radial surface 106c and the inner surface 106d extend between the connection surface 106a and the top surface 106b. The radial surface 106c is opposing and connected to the primary member 102 inner surface 102c and the connection surface 106a is coplanar with the bottom surface 102b of the primary member 102 and configured to connect to a top surface of the water storage tank (shown in FIG. 2). The majority of the surface area of the connection surface 106a of the connecting member 106 can be in contact with the top surface of the water storage tank, providing a sufficient fastening structure to secure the weight of a heat engine to the water storage tank (shown in FIG. 2). The top surface 106b of the connecting member can also be perpendicular to the supporting surface 104c of the stabilization member 104. The connection surface 106a can be parallel to the water storage tank top surface (shown in FIG. 2). The connecting member 106 can be configured to contain at least one fastening hole (shown in FIG. 4 and FIG. 6) that can pass through the connection surface 106a and the top surface 106d. The connecting member 106 can be connected to the water storage tank (shown in FIG. 2) using a fastener such as at least one bolt, a rivet, or a weld.

The offset mounting bracket 100 can be formed from many materials such as aluminum, steel, tin, or plastic for example. In some implementations, the primary member 102, stabilization member 104, and the connecting member 106 may be formed as separate components. Each of these separate components may be connected with welds, or fastening elements, such as rivets or bolts. The primary member 102, stabilization member 104, and the connecting member 106 may also be integrally formed. For example, the primary member 102 and the connecting member 106 may be formed from a single piece of material, which may be bent to form the separate surface planes of the primary member 102 and the connecting member 106. A joggle bend (shown in FIG. 5) may be formed in the single piece of material to form the stabilization member 104 with a plane that is displaced from a plane of the primary member 102.

FIG. 2 illustrates a side view of an implementation of a hot water supply system 200. The hot water supply system 200 can have the offset mounting bracket 100, a lower support bracket 202, a first heat engine 203, a second heat engine 204, and a water storage tank 206. The water storage tank 206 can have an inner volume configured to hold a volume of water. The inner volume of the water storage tank 206 is fluidically coupled to an outlet of at least one of the heat engines 203, 204. The water storage tank 206 can have a top surface 208, a bottom surface 210, and a cylindrical wall, 212 that extends between the water storage tank 206 top surface 208 and the water storage tank 206 bottom surface 210.

The lower support bracket 202 can also be connected to the water storage tank 206 cylindrical wall 212. The lower support bracket 202 can be an L-shaped bracket. In some implementations, the lower support bracket 202 can be configured to have a side surface 202a that connects to the cylindrical wall 212 of the water storage tank 206. The lower support bracket 202 can also have a bottom surface 202b. In some implementations the bottom surface 202b can be coplanar with the bottom surface 210 of the water storage tank 206. The side surface 202a of the lower support bracket can be perpendicular to the bottom surface 202b of the lower support bracket 202. At least one point on the lower support bracket 202 bottom surface 202b can be coplanar with the bottom surface 210 of the water storage tank 206. The lower support bracket 202 can stabilize a hot water supply system 200. Specifically, when a water storage tank 206 is not filled with water, the heat engines 203, 204 may displace the hot water supply system's 200 center of gravity and cause the possibility of tipping. The lower support bracket may provide additional stabilization in the direction of the heat engines 203, 204 and mitigate the possibility of tipping the hot water supply system 200.

The at least one heat engine 203, 204 can be mounted to the water storage tank 206 via at least one offset mounting bracket 100 and at least one surface adaptor 214. In some implementations two heat engines 203, 204 can be mounted to a water storage tank 206 via three surface adaptors 214 and an offset mounting bracket 100. Each of the heat engines 203, 204 can have top mounts 203a, 204a and bottom mounts 203b, 204b, such that one of the heat engine top mounts 203a, and bottom mounts 203b can each be connected to a surface adaptor 214 respectively. A second heat engine 204 can have bottom mounts 204b that are connected to a surface adaptor 214, while the top mounts 204a can be connected to the offset mounting bracket 100 primary member 102.

FIG. 3 illustrates an implementation of the surface adaptor 214, described above with reference to FIG. 2. The surface adaptor 214 has a planar fastening surface, which provides a surface adapted to connect to a heat engine, such as a heat engine top or bottom mount and provides an opposing curved surface which conforms to the cylindrical wall of the storage tank (shown in FIG. 2). This surface adaptor allows a heat engine (shown in FIG. 2) to connect directly to the cylindrical wall of the storage tank in situations where it is beneficial for the heat engines to be situated closely to the water storage tank and not on a separate mount (shown in FIG. 2). The surface adaptor can have a curved side 302 and a flat side 304. The curved side 302 can connect and fasten to a cylindrical wall (shown in FIG. 2). The flat side 304 can connect to a flat connecting surface such as a heat engine mount (shown in FIG. 2). The curved side 302 can have mounting holes (not shown) that connect to a cylindrical surface such as a water storage tank side wall and fasten thereto (shown in FIG. 2). The flat side 304 can also have mounting holes. The surface adaptor (shown in FIG. 2) can connect on the flat side 304 and the curved side 302 using at least one bolt rivet or weld.

FIGS. 4-6 illustrate several views of an embodiment of an offset mounting bracket 400. The offset mounting bracket 400 is substantially similar to the offset mounting bracket 100 described above. The offset mounting bracket 400 can be formed with embosses 402 that can relieve structural stress in the primary member 401 and can increase the structural rigidity of the primary member 401 which is substantially similar to the primary member 102 described above. The embosses 402 can be formed using a metal forming technique such as die pressing. In some implementations, the primary member 401 and the stabilization member 502 can be formed from a single piece of metal. The stabilization member 502 is also substantially similar to the stabilization member 104 described above. The stabilization member 502 can be offset from the primary member 401 by the joggle bend 504 as also described above. In other implementations, the stabilization member 502 can be connected to the outer surface 501 of the primary member 401. Additionally, the primary member 401 can have a cut-out 404 that saves weight and provides an additional handling surface for installation in high places such as the top surface of a water storage tank (shown in FIG. 2). In some implementations, the primary member 401 can have any number of fastening holes 406, such as four fastening holes or two fastening holes for example.

FIG. 7 shows an implementation of an offset mounting bracket 700 which has structural supports 702. The offset mounting bracket 700 can have a primary member 704, a connecting member 706 and at least one structural support 702. The at least one structural support 702 can connect the primary member 704 inner surface 702a to the connecting member 706 top surface 706a. The primary member 704 and the connecting member 706 can have at least one fastening hole 708 that may be used to fasten a heat engine as discussed in other implementations above. The connecting member 706 can connect to a flat surface such as the top surface of a water storage tank (shown in FIG. 2). The primary member 704 can connect to a heat engine as discussed above. The primary member 702 and the connecting member 706 can connect to another surface using at least one bolt rivet or weld. The structural supports 702 may strengthen the rigidity of the offset mounting bracket 700 to hold the weight of a heat engine. This may be especially useful in implementations where the primary member 704 and the connecting member 706 are integrally formed, or formed from a light weight material, such as aluminum.

FIGS. 8 and 9 show an implementation of an offset mounting bracket 800, which has a primary member 806, a plurality of structural supports 802 coupled along a length of the primary member, and a plurality of outer connecting members 804a, 804b coupled to the plurality of structural supports 802. The primary member 806 can have a top edge 806a, a bottom edge 806b opposite from the top edge 806a, a first edge 806c that is perpendicular to the top and bottom edges 806a, 806b, and a second edge 806d that is opposite from the first edge 806c and is also perpendicular to the top and bottom edges 806a, 806b. The primary member 806, which is substantially similar to the primary member 102, 401, 704 described above, can connect directly to a top mount on the heat engine 204, which can be a tankless water heater. Specifically, the primary member 806 comprises a plurality of fastening holes 808a for connecting the mounting bracket 800 to the top mount of the heat engine 204.

The primary member 806 is connected to the plurality of structural supports 802. One of the plurality of structural supports 802 can be connected along the first edge 806c of the primary member 806 and one of the plurality of structural supports 802 can be connected along the second edge 806d of the primary member 806. Therefore, each of the structural supports 802 has an edge that extends along a length of the first or second edge 806c, 806d. Each of the plurality of structural supports 802 has a top side 802a and a fastening side 802b. The top side 802a is coupled to the top edge 806a of the primary member 806. The fastening side 802b is coupled to the bottom edge 806b of the primary member 806. In some implementations, the plurality of structural supports 802 can have a curved side 802c that extends away from the primary member. The curved side 802c extends farthest away from the primary member 806 on the fastening side 802b and closest to the primary member 806 on the top side 802a. In various implementations, the curved side 802c may have a decay curve profile from the fastening side 802b to the top side 802a. The curved side 802c can allow an assembly tool to rotate with a substantial range of motion when used to fasten the primary member 806 to a surface via the fastening holes 808a.

In some implementations, the plurality of structural supports 802 can extend at an angle away from the primary member 806. In some implementations, the angle can be 90 degrees. In some implementations, the angle can be between 80-100 degrees. The plurality of structural supports 802, which are substantially similar to the structural supports described above in FIG. 7, can strengthen the rigidity of the offset mounting bracket 800.

Each of the plurality of structural supports 802 can connect to an outer connecting member 804a, 804b along the fastening side 802b. Each of the outer connecting members 804a, 804b extend in a direction away from the fastening side 802b of the structural supports 802 and parallel to the bottom edge 806b of the primary member 806. As shown, the connecting members 804a, 804b are perpendicular to both the primary member 806 and the structural supports 802. In other words, the connecting members 804a, 804b extend away from the first and second edges 806c, 806d of the primary member 806, respectively. The connecting members 804a, 804b have a rounded triangular shape with the base of the triangular shape connected along the fastening side 802b of the structural supports 802 and a height of the triangular shape spaced farthest away from the primary member 806.

Each of the connecting members 804a, 804b, can be configured to connect to a flat surface such as the top surface 208 of the water storage tank 206. In some implementations, the connecting members 804a, 804b have a plurality of fastening holes 808b therein. As shown, the fastening holes 808b are positioned away from the primary member 806. The connecting members 804a, 804b can be fastened to a surface using a fastener such as a bolt, rivet, or weld.

In some implementations the offset mounting bracket 800 can be integrally formed from a single piece of material. For example, the single piece of material can be bent, molded, or formed to include the primary member 806, structural supports 802, and connecting members 804a, 804b. In some implementations, the offset mounting bracket can be formed from 14-gauge steel. Rigid and formable materials, such as 14-gauge steel, can provide substantial structural rigidity for the offset mounting bracket 800 and provide structural support to sustain the weight of an attached heat engine such as a tankless water heater.
