District Heating and Cooling

How to achieve sustainable goals in cities

The power of networks. Cities have a central role to play in the transition to sustainable energy. They account for over 70 % of our global energy use, and half of that goes to heating and cooling. The best way to reduce primary demand is by collectivizing it through District Heating and Cooling networks. District networks offer the least-cost and most powerful solution to scale up efficiency for climate-proof and conscience-free energy.

Select your market

The UN estimates that modern district energy systems could result in a 7% reduction in overall capital investment in the power sector by 2030 – an investment savings of $795 billion by replacing the use of electricity for heating and cooling and thereby reducing peak and overall power demand. Cities, governments and independent agencies increasingly understand, and realize this potential, as demonstrated by UNEP, who launched a District Energy in Cities (DEC) initiative to facilitate our energy transition in this way.

Infrastructure to connect demand with supply

Managing interdependent services and utilities, cities are uniquely placed to enable the initiation and integration of such solutions. They can facilitate the infrastructure necessary to rapidly advance both energy efficiency and renewable energy. Both user and producer rely on networks that function as a locally attuned backbone that enable the energy exchanged between them. We strive for lower (total) investment per house connection, durability and system implementation reliability. Whether dealing with a greenfield roll-out, renovating or expanding an existing network, or retrofitting an existing community with a new network; Thermaflex ensures a future proof solution.

Total Benefit of Ownership

In order to meet current and anticipate future stakeholder needs, we drove innovation further with focus on Total Benefit of Ownership by network design, speed and quality of installation, environmental impact, efficiency, sustainability and logistics. New tailor-made solutions address key requests, like minimal disturbance to the existing environment and speed and safety of installation.
