Yes, heat pumps slash emissions even if powered by a dirty grid | Installing a heat pump now is better for the climate, even on U.S. electricity generated mostly by fossil fuels. Here’s why
Installing a heat pump now is better for the climate, even if you run it on U.S. electricity generated mostly by fossil fuels. Here's why.
The article doesn't go into it, but a key advantage they have is that heat pumps move heat, rather then trying to generate it. So they can move a lot more heat into your house than would be generated by running the electricity they use through a resistor. This makes them effectively more than 100% efficient (the exact amount depends on temperature) as compared with burning a fuel or resistive heat.
TL;DW (but you really should, it's a great video): "Recommended" heat pumps are often oversized and overpriced compared to what is actually needed, and homeowners need to be aware of this.
