Many older properties still run a basic electric hot water system or gas storage unit, so there is strong interest in electric hot water vs gas hot water, especially when rooftop solar is already installed. A modern electric hot water installation set up to run on solar can be a big step up in efficiency, even before you move to a dedicated solar hot water heating system.
