Pair comparison
Oil heating vs. heat pump (winter day)
One winter day
Switching from oil to a ground-source heat pump is one of the largest single emission reductions a household can make.
Dimension-by-dimension comparison
One winter day — absolute values
Both items scaled to the same unit (one winter day). Lower value = lower environmental impact.
