If you're cross-shopping point-of-use water heaters beyond AO Smith, the following brands also ship in this category:
Point-of-use (PoU) water heaters are small electric units installed near a single fixture — under a sink, in a remote bathroom, in an ADU, in an RV, or at a specialty application like a wet bar or workshop sink. They eliminate the long hot-water pipe run from the main heater and the chronic wait-time problem at distant fixtures. Two product types: mini-tank storage (4–20 gallons) and electric tankless (3–11 kW).
Small electric storage tanks (typically 4–20 gallons) that plug into a standard 120V outlet (smaller sizes) or 240V circuit (larger sizes). The 120V plug-in option is the big advantage — no electrical work required for under-sink installs.
