I’m well aware of how heat pumps work. What I meant by that was that some electrical grids, like Saskatchewan, for example, have a high GHG intensity. So, despite a heat pump’s high efficiency, it can still result in higher overall GHG emissions than if the same amount of heat were delivered by burning natural gas in a condensing furnace.
Now Saskatchewan has been making good progress on cleaning up their grid, so it might not quite be the case now, but energy and GHG modelling I did a couple years ago showed just the case above.
