Heat sources
We help commercial and industrial organisations to reduce their carbon impact by capturing wasted heat.
We are specialists in developing and building solutions that transform surplus heat into energy for our low carbon heat networks.
Where does the heat come from in our heat networks?
UK cities contain an enormous amount of unused heat. Heat networks capture that heat and use it to warm homes and businesses, reducing carbon emissions and creating significant benefits for businesses and communities.
