View heat register

The heat register provides you with information on municipal heat planning, building heat requirements, heat generation and heat distribution in Hamburg.

Detailed description

The heat register is an interactive map and a central planning tool for efficient and sustainable heat supply. It provides freely accessible information on the current heat infrastructure and potential improvements. It also publicly displays the results of legally required municipal heat planning.


The heat register supports you and the City of Hamburg in implementing sustainable heat supply concepts and helps you make well-founded decisions regarding energy supply.


The goal is to identify energy- and cost-efficient measures and optimally link urban development and urban land-use planning. For example, analyzing the settlement structure can help identify suitable solutions for heating buildings, such as district heating or heat pumps.
