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.

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.

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.
