Overview
Bosch sized this mini tank to sit under or beside a sink, tapping the cold line to deliver hot water at that fixture. It can also run in line with the main heater to shorten the wait for hot water.
Removing the long wait at a far bathroom or adding hot water to a garage sink is where it earns its place. It needs hardwiring rather than a plug, and the tank holds enough for hand washing, not showers.
Who it's for
Homes with a sink far from the main heater, or a workshop sink with no hot line. Buyers who want to plug it into an outlet should look for a cord connected model.
Pros and cons
- Hot water at the fixture
- Wall bracket included
- Glass lined tank
- Relief valve built in
- Must be hardwired
- Small tank for showers
- Recovery time not listed
Performance notes
Hot water output depends on tank volume and element wattage; once the tank is drawn down, it needs time to reheat. Installed in line, it fills the gap while hot water travels from the main heater.
