Been a little while since I looked up the utility rates, but last I remember gas is about 1/7 the cost of electricity in Saskatchewan. Makes it hard to justify heat pumps for heating in most places. Hope the technology continues to improve and it’ll be a more sustainable option when we have a more sustainable grid.
Gas furnaces achieve about 96-98% efficiency. Heat pumps achieve 300-400%. So you have to factor that in.
There's still a cost difference but the hope is for governments to start supporting serious nuclear energy to drive down electric costs. It'll take time but natural gas will become less economical as decades go on especially with investments.
How does something achieve 300-400% efficiency?
Refrigeration cycle can get crazy efficiencies like that because it is transferring energy from one side of the system (indoor unit) to the other (outdoor unit). The amount of energy that is transfered is greater than the amount of energy required to push the refrigerant through the system.
