Electric water heaters are the least expensive to purchase and install. They also cost more to run in most areas than gas or propane heaters. Gas and propane heaters are more popular because they are more efficient, but they cost more upfront. The best quality heaters can be electric or gas but often have many modifications to make them ultra-efficient. This includes condensing the fuel, heated coils in the center, and better insulation.
