How does this compare to the energy efficiency/cost of gas-powered water heater?
- midoridensha 4y agoI don't see how you can compare energy efficiency between something powered by electricity and something powered by natural gas. They're two entirely different energy sources. The electric one doesn't involve putting more CO2 into the atmosphere, at least directly. And cost is completely variable, as electric and gas prices both vary wildly depending on location and time (gas became much more expensive in the last year).
- BlueTemplar 4y agoTypically much better efficiency since a gas heater is only 100% efficient, maybe up to 200% relative efficiency if the electricity comes from a faraway gas turbine. Cost difference is going to vary by an order of magnitude (and more) depending on the local conditions : https://news.ycombinator.com/item?id=34242237 https://news.ycombinator.com/item?id=34242237
