Bosch Tronic 7000 C 10-Gallon Mini Tank Water Heater

The Bosch Tronic 7000 C 10-gallon mini-tank is Bosch's largest point-of-use water heater, positioned for applications where a 2.5-gallon or 4-gallon unit is undersized but a full residential storage tank is too large. The 10-gallon capacity covers small household uses: a guest bathroom shower, a finished-basement secondary bath, an outdoor kitchen or pool house bath, an in-law apartment kitchen sink.

Specs: 10 gallons stored, 1440W heating element on 120V (no 240V required), recovery rate roughly 8 gallons per hour, ENERGY STAR certified at UEF 0.90+, vacuum-insulated tank for low standby losses. Wall-mount or floor-stand. About 16" diameter × 24" tall.

The 120V power requirement is the defining advantage versus larger residential tanks. Any standard outlet works — no panel slot, no 240V circuit, no electrician required for typical installs. This makes the Tronic 7000 the right answer for finished-space additions where running a new 240V circuit would require significant electrical work.

Capacity calculation: 10 gallons stored plus 8 gph recovery means about 18 gallons in the first hour. That covers a single shower (17 gallons for a standard 8-minute shower) with minimal headroom. For households running back-to-back showers or filling a kitchen sink during shower use, the 10-gallon is undersized — step up to a full residential tank.

Right uses: secondary bathrooms in finished basements where main heater is two floors away, guest house kitchens, pool house bathrooms, in-law suite installations. Wrong uses: primary household water heater (insufficient capacity for normal family demand), high-volume utility applications.

5-year warranty on the tank, 1-year on parts. About $350 unit. Self-installable for any homeowner with basic plumbing skill — 1/2" NPT supply connections, T&P safety valve included, mounting bracket included.
