But which is more efficient?

Derek Cole compares gas and electric heating systems. Modern gas furnaces hit 95-98% efficiency, but heat pumps paired with a backup gas furnace (dual-fuel) can be more efficient overall. Your climate and whether you have a 100A or 200A electrical panel determine which makes sense for your home.

What is more efficient gas or electric heat? Today they make 95, 98% efficient furnaces. I mean it's crazy. So basically what that is saying is for every dollar you spend in heating, you're getting 95 cent of heat in the house. The other 5 cent is going up to flue. Now with combustion you're always going to have some kind of loss. It's never going to be 100% efficient, whereas electricity is 100% efficient because there is no loss. It is efficient that way. The problem becomes when it gets cold outside, whereas you're using the strip heater or the back of emergency heat and that's 100% electricity. And you go out to your panel where your power comes in, you set a little thing that's like spinning like crazy and it's like whoa. It's because you're using electric heat and you don't have that gas. I mean if you go to a, to a house, especially older homes with all gas appliances, they have a gas furnace, they have a gas dryer, they have a gas stove, they have a hundred amp panel in the house, that's not a lot of electricity. Whereas you go to a newer home with all electric, like my house, you know, everything is electric, stove, heat pump, dryer, everything's electric. We have a 200amp panel. We use more power. So it's kind of a give and a take, use more power. But if that's the way you want to go, that's fine. Again, the most efficient way is really dual fuel. I mean if I could, I'll just use me for example, if I could have natural gas at my house. So that ends, I think it's like four or five houses down the road. Natural gas is right there. So if they brought that to me, I would take it, I would switch up my unit to a dual fuel, keep my heat pump, put it in the gas furnace, probably a 95% gas furnace, and use that natural gas heat because it is more efficient. And natural gas is probably the best source you got. I mean if you have a choice between natural and lp, you want to pick natural. LP is a little more corrosive. It's just that in nature it has a little more water into it because it's a man made thing, whereas natural gas is natural. So it's not as corrosive. So depends on the climate. I mean if I'm in, if I'm in Florida, you know, I'm using all electricity and I'm probably not using heat that much either. I'm using ac, but if I'm in North Dakota, I'm killing out some boilers and some oil and some gas and, you know, it's more efficient to use that up there.
