Heat pumps twice as efficient as fossil fuel systems in cold weather, study finds
(www.theguardian.com)
Finally someone taking sense.
Asking me to compare my own bills between natural gas and heat pump is insanity, I don't have both systems installed just for shits and giggles.... but it doesn't seem to stop people from saying I should do that sort of insane thing to really know.
That site sure is interesting, I haven't dived into the data enough to know how they got the figures they did, or what it represents... but assuming they're saying that it's saying that $0.63 worth of natural gas gives you the equivalent thermal output of 1kWh of conventional electric heating (more or less)... which I think it kind of does, since, to the best of my knowledge, electric heating systems are among the most efficient at converting 100% of the energy input to heat output (or as close as we can get to that). As we know heat pumps exceed this because they're not generating heat, they're just moving it around.
Also, a blanket statement like "heat pumps should be able to beat 2.6 SCOP, even in Canada" is problematic, since Canada is huge, and some of that landmass is in the Arctic circle. To be fair, 90% of Canada's population (or something similar to that) is in the southern 10% of the landmass.... still. If we're being detailed, then such blanket statements should be avoided. A good alternative is "for the majority of the population of Canada", which is wholly accurate.
There's also other inefficiencies that aren't being considered and unless we get really deep with the information, that fact is unlikely to change; however, those inefficiencies may make heat pumps even better on paper....
There's a lot to say about this incredibly complex topic. And that's not even touching on the nuances of the word "efficiency".... since efficiency relies on specific conditions, and usually is a comparative figure. Eg, the Ford F-350 super duty is an extremely efficient vehicle, when compared to the Ford model T.... many decades of innovation will pretty much guarantee that statement is accurate. But comparing the F-350 to, say, a Toyota Prius on MPG alone, then the F-350 seems like a gas guzzling bohemouth, that's a symbol of gluttony.... Wasting so much more fuel, to travel the same distance. Both saying that the 350 is incredibly efficient and also that it's extremely inefficient, these are both true, depending on context.
There's too much nuance here that I'm just going to stop talking before I ramble myself into getting cancelled somehow.
