Oxford study proves heat pumps triumph over fossil fuels in the cold::Published Monday in the scientific journal Joule, the research found that heat pumps are two to three times more efficient than their oil and gas counterparts, specifically in temperatures ranging from 10 C to -20 C.
Hah look at the downvotes, you can’t have civilized discussion these days.
Your last paragraph and my last sentence is the whole culprit for me. The money I have to pay here for good heat pump with COP 2 at -30 and the associated electric bills have currently no chance here to ever be cheaper than burning gas either nor more friendly for the climate where my government burns coal to produce electricity.
And no, I cannot install enough solar to power this heat pump in the winter or offset the cost of electricity during summer (inverters already turn off in the summer, no electricity is produced as too many neighbors have solar and voltage rises above shutdown threshold in the grid)
Solar in winter for high latitudes is never gonna work, fully agree on that.
But at some point a hybrid system will be cheaper for part of the year than a pure gas system, at any latitude.
Whether it justifies the investment is indeed a cost/benefit analysis.
Downvoting on Lemmy is toxic, fully agree on you there. It really stifles healthy discussion. It seems Lemmy is engineered by communists who only want agreement lol. 😂
