Energy Efficiency

With our advanced digital-based products and services, we help to make buildings climate-friendly, safe and comfortable.

We provide a comprehensive package of energy management services, based on a wide range of high-quality metering equipment and the most convenient way for data readout. We offer the entire process as a one-stop solution. Our range of products and services covers the supply, installation and commissioning of meters accompanied by detailed consumption-dependent billing of energy, water and ancillary costs.

Only pay for what you consumed.

We issue millions of consumption-based bills annually – a service with sustainable success. The fair distribution of energy costs and individual billing motivate residents to save energy - up to 25% according to the European Commission.

In every country we offer tailor-made solutions with our data management system contributing to governmental efforts to reduce energy.

Detect & Protect

We ensure a safe and secure living environment. Our digital-based smoke alarm devices help to save lives and make residents feel more safe and comfortable at home. With optional maintenance services we ensure that the devices are regularly checked and functioning.

Feel safe at home.

Our drinking water analysis offers protection against potential risks in drinking water and our humidity sensor helps to keep a good and healthy room climate at home.

Our long-standing expertise in collecting and dealing with water consumption data, helped us to develop a highly sophisticated algorithm which detects water leakages in properties and immediately alerts property managers or owners.

Our R&D

As the innovation driver of our industry, we invest over 100 million euros in our digital devices and infrastructure every year. Today, we already have more than 25 million connected devices in use. Heat and hot water consumption can therefore be read directly by radio without a meter reader having to enter the apartment. More services for the intelligent multi-family building ("smart building") will be added in future.

Quality developed in Germany

All ista products – from digital metering devices for heat energy to smart smoke alarm devices – are being developed in the “ista Technikum”, our technology lab based in Essen, Germany. Here we are pooling the entire research and device development, from the first concept idea to market maturity, at one location. Please have a look behind the scene:
