Abstract
A system for monitoring the use of heat energy in water devices in an individual unit of a multi-unit complex wherein the multi-unit building is supplied water from a common source and the individual unit has a plurality of energy consuming water devices each supplied by supply and return water pipes supplied from said common source. The system comprises a monitor for monitoring the flow through each of the water pipes which will determine that successive volumetric flow units have flowed through the pipe, define the heat energy of each of the successive volumetric flow units, and compute a total heat energy removed from the successive volumetric flow units, and periodically transmits the total heat energy consumed from the successive volumetric flow units, and a remote receiver which receives the total heat energy transmitted from each of the plurality of monitors and computes a total heat energy use for the individual unit for a selected period of time.
