Heat Networks & Net Zero
Heat Networks (also known as communal or district heating schemes) are the net zero solution of choice supplying low carbon heating, hot water, and/or cooling efficiently to modern-day apartment blocks.
The benefits of the economies of scale have been identified by national government, and now the use of advanced technology and carefully engineered heat networks is almost standard practice for more densely populated urban environments.
