District heating 

Safe. Efficient. Environmentally friendly.

District heating is the safest, most sustainable heating solution for cities and district areas. You’ll find district heating in action in parts of Europe, particularly the Baltic and Nordic countries, Germany, and the Netherlands. At Gren, we have more than 20 years’ experience supporting towns and cities with reliable district heating networks.

How it works?

District heating is a centralised system that produces and distributes heat to multiple buildings or residences – from a central source. Usually, hot water or steam is generated in a central facility and then circulated through a network of pipes to provide space heating or hot water for multiple people to use.

This shared approach boosts energy efficiency, integrating various heat sources into a single, sustainable heating solution.

Better urban air quality

With distinct heating, fuel is used efficiently. It also significantly improves air quality in our cities, thanks to reduced emissions of fine particles and dust.

More flexibility

Distinct heating can be flexibly scaled. When extending a property, there’s no need for large additional investments in existing heating solutions.

Greater cost-efficiency

With minimal maintenance and inspection costs, low initial investments for connection, and professional customer service, district heating is a cost-effective solution.

Towards Net Zero

At Gren, we believe district heating can play a powerful role in our shared decarbonisation journey, helping drive efficiencies and reduce emissions. Internationally, it’s proven to decarbonise heat at scale, supercharging progress towards net zero targets and readying our homes, industries, and public services for a positive future.

As well as uncovering opportunities to use waste heat, distinct heating supports flexibility. Many different technologies can provide the input to a heat network. When a system has centralised thermal storage or uses multiple heat sources, district heating makes it possible to shift demand. All Gren’s assets use locally sourced fuels.

Low-carbon heat. At scale.

District heating uses a singular central heat source to distribute hot water to multiple individual dwellings through a network of insulated pipes.

Usually used to take care of heating and hot water needs in apartment complexes and large-scale buildings, it’s a cost-effective, low-carbon solution that benefits people and the environment.

Energy on Clyde with Glasgow

We are working with Glasgow to develop secure and cleaner energy in the city that will benefit local businesses, people, and the community.

Currently just 2% of the UK’s heat is supplied by district heating networks. With an estimated 50% of buildings in the UK located in areas of suitable density for heat networks, the system has the potential to have a far greater impact.

Impact in Latvia – innovating district heating

Gren’s combined heat and power plant in Jelgava uses local renewable energy resources – mostly wood chips – to provide district heating to customers.

The largest plant of its kind in Latvia, the facility has improved the overall efficiency and security of district heating, reducing CO2 emissions from heat production by 90%.
