Smart Leak Detection for Heating Applications

Did you know that mid-sized utilities in Denmark lose a daily average of 30 m³ in leaks within their heating network? And their counterparts in Germany experience daily losses of 50 m³? If you’re a heating utility, leaks are one of the most costly problems you’ll face.

The cost is not just financial; it’s also environmental because a leak is essentially a wasted resource. What’s more, if that leak occurs in a pipe inside a consumer’s home, it can cause major structural damage to the building, resulting in yet more costs and impacting your customer satisfaction.

So, how can you limit the cost of leaks? How can you make sure you intervene promptly to avoid major damage? What can you do to reduce the risk of leaks happening in your network? And how can you achieve all this while offering new services and added value to your customers?


The key to managing leaks is to be informed quickly and act rapidly. And that’s exactly what Smart Leak Detection allows you to do. This powerful solution is part of Diehl Metering’s Energy Network Analytics, an offer that makes heating networks more intelligent.

To benefit from our Smart Leak Detection solution, you need a fixed network. In combination with SHARKY heat meters, this allows data reading to be fully automated. In addition, SHARKY FS ultrasonic flow sensors are installed in the return pipes of the heat distribution network.


By monitoring flow rates in the forward and return pipes, Smart Leak Detection can detect a leak in the very early stages. Any deviation from the predefined range of flow rates immediately triggers an alarm. Within 90 seconds of an anomaly occurring, the SHARKY heat meter sends a warning message. This then shows up with precise information about the location and nature of the problem on the Central Data Management software – IZAR@NET 2 if hosted locally on your server or IZAR PLUS PORTAL if you prefer Software as a Service.

Furthermore, you can follow the flow rates in different parts of your network on IZAR@NET 2 through easy-to-understand graphics and clear analytics that are regularly updated. This means you can detect less obvious types of leak, such as a dripping radiator in a consumer’s home.


With Smart Leak Detection, all the processes in your network run more efficiently, helping to reduce operating costs. From the heating plant to distribution in individual homes, you’ll have a clear overview of flow rates, with alarms enabling you to swiftly resolve any problems before costly damage is done. And by heat loss through leaks, you’ll not only positively impact your bottom line; you’ll also boost the sustainability of your business.

The solution also opens up the possibility of creating new services for your customers. Smart Leak Detection can be customized to send leakage alarms directly to consumers, helping to drive customer satisfaction while also reducing the risk of structural damage. In certain countries, smart meter infrastructures entitle consumers to discounts on burst-pipe insurance – meaning you’ll be even more popular with your clientele.
