Helsinki has advanced integrated district heating and cooling. Over 300 MW of heat pumps by 2025. Collecting heat from wast water is free energy. When you defecate, wash clothes or dishes, or take shower there is warm water and solids going down the pipes. That heat can be used. In the summer stored cold sea water can provide district cooling. |
