BACKGROUND OF THE INVENTION [0001] 1. Field of the Invention [0002] The invention pertains to the field of residential and commercial heating. More particularly, the invention pertains to a modular heat distribution unit for a hydronic heating system. [0003] 2. Description of Related Art [0004] A typical modern hydronic heating system includes three basic components: a boiler, baseboard panels or radiant in-floor heating pipes (referred to herein as heating assemblies), and an arrangement of plumbing and electronics connecting the other two components and controlling heat flow. Many types of boilers are readily available on the market. The baseboard panels or the in-floor heating pipes must be installed on the job site for obvious reasons. This work is relatively simple and straightforward, and it is usually efficiently accomplished in the early stages of building construction. For hot water baseboard heating, hot water baseboard panels are connected by tubing to create several heating zones. For radiant floor heating, multi-loop zones of pipes are built into the floors of the building. [0005] The said arrangement of plumbing- and electronics may include pipes, insulating valves, gauges, circulators, air purgers, expansion tanks, pressure reducers, check valves, drain valves, mixing valves, electronic controls, and electric wires. This arrangement is commonly referred to as the heat distribution center of the heating system. The heat distribution center is the most complicated, expensive, and time-consuming component to construct. The heat distribution center connects the boiler to the baseboard panels or in-floor heating pipes and regulates heat flow to the panels or pipes. The heat distribution center is typically custom-designed and built on the job site for each individual building. However, it is rarely organized as well-defined in a spatial sense, and it is usually fairly complicated, especially in hydronic radiant heat floor cases. This results in high costs, uneven quality, and significant delays on the job site. There is no standard way of designing a distribution center, so each center is different and reflects the individual designer's preferences. Often the on-site-constructed distribution center design decreases the energy efficiency of the heating system. [0006] A.I.M. Radiant Heating markets a "Boiler Room in a Box" that is preassembled in a primarily two-dimensional layout. The box is typically wall-mounted and requires a large amount of wall space which often may not be available in a building. [0007] There is a need in the art for a mass-producible, transportable, compact, fully-assembled modular heat distribution unit that may be connected on-site within hours to any hot water source, to any arrangement of heating assemblies, and, if necessary, to any indirect water heater. SUMMARY OF THE INVENTION [0008] A compact modular heat distribution unit for a hydronic heating system connects to a hot water source, to supply and return pipes that lead to heating zones of the building, and, optionally, to an indirect water heater. The module is preferably assembled off-site in a factory setting to contain all components of a typical hydronic heating system except for a hot water source and the building heating pipes. The module includes heating zone distribution sub-modules for the different heating zones of the building. A three-dimensional frame supports the heating zone distribution sub-modules. The module may be used in any multi-zone system including hot water baseboards, hydronic radiant heat floor pipes, swimming pool heaters, ice melt systems or in any combination of these zones. [0009] In one embodiment, a modular heat distribution unit of the present invention regulates heat flow to a plurality of heating zones. The modular heat distribution unit includes a hot water supply manifold, a plurality of heating zone distribution sub-modules, a return water manifold, and a three-dimensional frame. The hot water supply manifold is supplied by a hot water source. The heating zone distribution sub-modules are supplied by the hot water supply manifold. The return water manifold collects return water from the heating zone distribution sub-modules and returns it to the hot water source. The frame supports the heating zone distribution sub-modules. The hot water supply manifold and the return water manifold are arranged such that the heating zone distribution sub-modules are stacked with respect to each other. [0010] The hot water supply manifold and the return water manifold are preferably oriented substantially vertically. In one embodiment, the hot water supply manifold and the return water manifold are arranged on diagonal corners of the modular heat distribution unit. In a preferred embodiment, each of the heating zone distribution sub-modules includes at least one supply connecting element for supplying water to at least one heating line of one of the plurality of heating zones and at least one return connecting element for receiving water from the heating zone. Each of the plurality of heating zone distribution sub-modules preferably includes a zone controller for controlling a water circulation in its respective heating zone. The zone controllers preferably include zone circulators stacked with respect to each other. [0011] Each of the heating zone distribution sub-modules is preferably a radiant floor heating zone distribution sub-module for distributing to a radiant floor heating zone, a baseboard heating zone distribution sub-module for distributing to a baseboard heating zone, a domestic hot water zone distribution sub-module for distributing to a domestic hot water zone, a swimming pool sub-module for distributing water to a swimming pool heating zone, an ice melting sub-module for distributing water to an ice melting heating zone, or a spare zone distribution sub-module. The radiant floor heating zone distribution sub-module preferably includes a mixing valve, a supply header having a plurality of supply outlets, a return header having a plurality of return inlets, and a plurality of connecting elements connecting the mixing valve, the supply header, and the return header. The modular heat distribution unit preferably includes a make-up water sub-module for regulating delivery of water to the modular heat distribution unit and to the rest of the system. The make-up water sub-module preferably includes a feeding valve, a backflow preventer, a pressure reducer, a bypass valve, a drain valve, a heating water expansion tank, and a plurality of connecting parts connecting the feeding valve, the backflow preventer, the pressure reducer, the bypass valve, the drain valve, and the heating water expansion tank. [0012] The modular heat distribution unit preferably includes an electronic sub-module for monitoring thermostat settings and readings for the heating zones and controlling water flow appropriately. The modular heat distribution unit is preferably constructed off-site and requires only on-site coupling to the hot water source, tubings of the heating assemblies, thermostat wiring, and a power supply. Each heating zone distribution sub-module preferably supplies one of the heating zones. [0013] In one embodiment, the heating zones include at least one radiant floor heating zone and at least one baseboard heating zone, and the heating zone distribution sub-modules include at least one radiant floor heating zone distribution sub-module for the radiant floor heating zone and at least one baseboard heating zone distribution sub-module for the baseboard heating zone. [0014] In another embodiment, the modular heat distribution unit includes a plurality of heating zone distribution sub-modules arranged in a three-dimensional layout and a three-dimensional frame supporting the heating zone distribution sub-modules. The frame preferably has a rectangular parallelepiped shape. [0015] In another embodiment, a method of assembling a hydronic heating system for a building includes manufacturing a modular heat distribution unit off-site. The modular heat distribution unit includes a plurality of heating zone distribution sub-modules arranged in a three-dimensional layout and a three-dimensional frame supporting the heating zone distribution sub-modules. The method preferably includes installing a plurality of building heating assemblies in the building. The building heating assemblies are baseboard heating assemblies or radiant floor heating assemblies. The method preferably also includes installing at least one thermostat in the building. The method preferably further includes transporting the modular heat distribution unit to the building and connecting the modular heat distribution unit on-site to a power supply, to the thermostat, to a hot water source, and to the building heating assemblies. [0016] In another embodiment, a method of producing a modular heat distribution unit includes assembling a plurality of frames, assembling a plurality of heating zone distribution sub-modules, assembling a plurality of hot water supply manifolds, and assembling a plurality of return water manifolds. The method also includes selecting a selected frame from the frames, a plurality of selected sub-modules from the heating zone distribution sub-modules, a selected supply manifold from the hot water supply manifolds, and a selected return manifold from the return water manifolds. The method further includes attaching the selected sub-modules to the selected supply manifold, the selected return manifold, and the selected frame.
