For the simple reason that every house must have a water heater anyway, and that many already have an electric one.

Water heater - yes. Water tank? Not necessarily. They take up a non-trivial amount of space and even then they have limited capacity. Also in my part of the world gas is cheaper than electricity, so people tend to use gas to make hot water.

Newer heatpump-based water heaters are actually more efficient than gas heaters. As in: it's more efficient to burn the natural gas, use it to drive a turbine and generate electricity, and then use it for water heating.
