Direct electric heating emissions

The emissions per kWh of heat supplied are equal to the sum of the emissions related to the electricity production and distribution plus the emissions of the production, installation and decommissioning of the direct electric heating system.

The emissions related to the electricity supply (production&distribution) cannot be calculated as they are scenario dependent.

The emissions related to the production, installation and decommissioning of a direct electric heating system come from the Ecoinvent V2.2 dataset [1]: auxiliary heating, electric, 5kW, at plant, CH, [unit].

CO2-eq. emissions [kgCO2-eq./unit] 6.71
Deposited waste [UBP/unit] 1423

Knowing the capacity factor (0.3) and the life time of the system (25 years), the emissions per kWh of heat supplied can be calculated:

CO2-eq. emissions [kgCO2-eq./kWhth] 5.67E-06
Deposited waste [UBP/kWhth] 0.0012

If these emissions are compared to those for the actual electricity supply in Switzerland (0.125 kgCO2-eq./kWhe and 179.27 UBP/kWhe), it can be stated that the emissions attributed to the heating system are negligible.
