A heat network distributes heat to several users, just as an electricity grid distributes power.
The heat energy produced and recycled by Combined Heat & Power plants during electricity generation can be sold and distributed to local homes and businesses via a heat network. Several thousand homes can be connected to a heat network.
Heat networks can also be constructed to distribute heat from Geothermal energy.
The networks have a long lifetime and are flexible to almost any source of available heat.
Recycling heat in this way has an important role to play in the reduction of carbon dioxide emissions. It is estimated that for every 100,000 MWh of energy supplied via heat networks, 31,000 tons of carbon dioxide emissions are avoided.
