Reduce primary and final energy demand.
Likely to decrease electricity demand by displacing electric forms of decentralised heating, unless the share of centralised heat pumps increases significantly.
Likely to reduce total consumption of heating oil and natural gas as centralised boilers and cogeneration are more efficient than decentralised solutions.
Impact on the grid depends on the type of technologies chosen.
Likely to increase energy independence by decreasing fossil fuel imports.
Very likely to reduce global CO2 emissions.
Likely to reduce deposited waste.
Other impact categories are technology specific.
Cost of the energy transition, impact on Balance of payments and Confederation income, depend on the technologies chosen.
With District Heating, heat that is generated ‘centrally’ is distributed through a network of pipes to the end users (a household or medium or large size industrial facility). The heat can be generated with various technologies and in the calculator, Central Heating is represented by the following technologies: Centralised Heat pump, Cogeneration, Centralised Boiler and Deep Geothermal.
• Requires district heating infrastructure (network) which can be capital intensive to deploy, particularly as a retrofit.
• Currently low energy prices make the economics of such an integrated energy system quite challenging without significant policy drivers.
