Pennsylvania children living near the sites at birth were two to three times more likely to be diagnosed with leukemia between ages 2 and 7, a new study finds.
Well the whole point of a heat pump is that they have a COP (coefficient of performance) of about 2-4. Meaning that for every unit of energy u put in they have an effective heating/cooling capacity of 2-4 units of energy. They have an effective efficient of greater than 100% whereas a gas can only every reach a max of 100%.
At ideal conditions. As the temperature difference is greater, the efficiency goes down. So right when you need heat the most, gas is still at 90+% efficiency while heat pumps are closer to or under 200%.
Then you have to look at capacity. It can be expensive sizing for the greater temp differences when it usually isn’t. If you have a heat pump that can be 400% efficient, do you really want to pay for quadruple the capacity so that even when it’s at 100% efficiency it still puts out enough heat? No one can afford that
