1. A system for monitoring the use of heat energy in a plurality of energy consuming water devices in an individual unit of a multi-unit building wherein each energy consuming water device is supplied by a water pipe comprisingat least one monitor for monitoring the flow through each of the plurality of water pipes, each of said monitors includingmeter means for determining that successive volumetric flow units have flowed through the pipe,temperature sensing means for sensing the temperature of the water flowing through the water pipe,multiplying means for defining the heat energy of each of said successive volumetric flow units by multiplying the temperature times the increment of flow,totalizator means for computing a total heat energy for said successive volumetric flow units, anda transmitter for periodically transmitting said total heat energy for said successive volumetric flow units, anda first remote receiver for receiving the total heat energy transmitted by the transmitter of each of said plurality of monitors and periodically retransmitting the total heat energy received from each of the monitors, anda second remote receiver for receiving the total heat energy for each of said monitors retransmitted from said first remote receiver and for periodically computing the total heat energy of the water for said Plurality of monitors.
