The advantages of DHC networks in terms of efficiency, environmental sustainability; the quality of the energy supplied; and job creation present an opportunity for the future that cannot be missed for a country like Spain which is energy-dependent. Let’s remember that DHC networks are a convenient and sustainable way to heat or cool the air and produce hot water, and can cater for shops, residential or public buildings.
The fundamental idea behind the concept of district heating is to use the surplus (which would otherwise be wasted) from energy production, from fossil fuel and biofuel refining and also from industrial processes. In addition, a district heating network can leverage various types of renewable energies (biomass, geothermal or solar thermal).
City cooling systems are an environmentally optimum solution, using local natural resources to produce cooling where and when it is actually needed. Customers are connected to the cooling system through a network of pipes which supplies cold water to buildings. The cold the system gradually loses makes the interior temperature drop.
