Catch dysfunctional water heater
If your boiler waste a lot of energy, no-one will complain as long as there is hot water in the tap, but your bill might blow up. Map the consumption profile of your water heater, to catch heaters that spend a lot of energy when there is no need for hot water.
Sensors used: PowerMoni Spot, FlowMoni Spot, HeatMoni Spot, PowerMoni Pro or PowerMoni Pro-C.
Method: The sensor is mounted on the supply cable/pipe for the boiler. If the week/day profile of the consumption does not follow the need for hot water, there is a large waste of energy and money.
