Reduce final energy demand slightly.
Likely to increases total fossil fuel demand.
Likely to decrease energy independence and energy security by requiring greater fossil imports.
May reduce global CO2 emissions slightly.
Risk of leaks of ammonia or lithium bromide
Likely to increase the cost of the energy system transition.
Likely to increase the cost of an individual heating system particularly if a ground-heat source system is used.
May worsen balance of payments by substituting oil imports for domestic electricity.
May increase Confederation income from the tax on mineral oil under the current taxation system.
An absorption heat pump is a device that draws heat from the environment and delivers it to a space to be heated at a higher temperature using an evaporation – compression – condensation – expansion cycle. Absorption heat pumps are driven using high grade heat which, in distributed applications would likely come from the combustion of natural gas or heating oil, or possibly geothermal sources.
• Absorption heat pumps are best suited to locations without connexion to the electricity grid and access to sources of heat such as geothermal, which limits their applicability.
Next tables contain the assumptions that have been introduced in the Thermal heat pump model of the calculator.
