A system for billing individual units of a multi-unit building for water use or water related energy use wherein the multi-unit building is supplied water from a common source and the individual unit has a plurality of water using structures each supplied by one or a pair of water pipes supplied from a common source. The system includes a monitor for determining the volumetric flow through each of the water pipes and/or the temperature of the water and periodically transmits a signal encoded with the volumetric flow and temperature or the heat energy used and the identification of the individual unit. A remote receiver receives the encoded signals from each of the monitors, defines a total volumetric flow of water and/or total heat energy use for the individual unit for a selected period of time, computes a water consumption/heat energy charge and prepares and forwards a bill to the individual unit.
A system for computing a charge for the water related energy use of an individual unit of a multi-unit building wherein the individual unit has a plurality of energy consuming hot water devices which discharge hot water during use, each supplied by a hot water pipe, comprising
A system for computing a charge for the water related energy use of a device which consumes hot water during use in an individual unit of a multi-unit building wherein the device is supplied by a hot water pipe, comprising
