Greenhouse Gas Emissions

Table 5 lists the greenhouse gas emissions for an electric resistive heater system, a ducted gas system, a reverse-cycle air-conditioner, a Solectair only system, a Solectair with gas assist and a Solectair with reverse-cycle air-conditioner assist. The values for all cases (with the exception of the Solectair Only case) is for the systems to supply 5013 kWh of heat as per Table 1. In the Solectair Only case, the heat supplied is 3526 kWh. The data is also shown in Graph 18 (over).

Table 5: Greenhouse Gas Emissions for different heating systems.

The Solectair HTS gives a very considerable greenhouse gas (GHG) emissions reduction. For a house similar to that as the Solectair Test House, the addition of a Solectair HTS to a ducted gas heating system can reduce the GHG emissions by as much as 53%. A Solectair HTS fitted to a reverse cycle air-conditioner can reduce the GHG emissions by as much as 48%.
