District heating networks are a proven solution for delivering heating, hot water and cooling services through a network of insulated pipes, from central points of generation to the end user. They are suited to feed in locally available, renewable and low-carbon energy sources; solar thermal and geothermal heat, excess heat from industry and commercial buildings as well as heat from combined heat and power plants. The ability to integrate diverse energy sources means customers are not dependent upon a single source of supply.
Owners or tenants of homes, offices, hotels or public facilities.
2. Combined heat and power (CHP) plant
In combined heat and power plants electricity and heat are generated in an environmentally-friendly, coupled process. They are fed into the electricity or the district heating grid. The district heating grid provides heating and hot water for offices, public facilities and homes.
3. Heat pump
Heat pumps offer energy-efficient alternatives to other heating methods like furnaces or air conditioning. They move rather than generate heat and can provide space conditioning, i.e. heating or cooling. Heat pumps work well in climates with moderate climate conditions.
Heat is generated through the incineration of combustible waste which is a way of recovering its energy, i.e. heat from waste.
5. Industry excess heat
Processes of heat intensive industries like refineries, iron mills etc. offer the potential for recovering 'waste' industrial heat which could be used to supply a range of energy demands, e.g. district heating networks.
