Some years back, This Old House was touting this technology (I don’t remember what it’s called) that was basically a small-ish electric heater attached to the water line at each sink. I don’t recall if this eliminated a water heater completely – I hope not.

The is at least one thread here on the subject. The gas ones, I think, work better, but AAUI the design requires small-diameter tubing to work well, which makes them susceptible to calcification.
