Bosch Tronic Heat 3000 US7 3.6 GPM Electric Tankless Review

The Bosch Tronic Heat 3000 US7 is a 3.6 GPM electric tankless water heater. Larger variant of the US3 (1.5 GPM). Sized for moderate single-fixture demand in warm climates.

Specs: 15 kW, two 50-amp double-pole breakers at 240V, 3.6 GPM at a 35°F rise. Stainless steel heat exchanger. German-engineered with smooth temperature modulation.

The 3.6 GPM capacity covers 1-bath warm-climate primary residence use. Above point-of-use, below typical whole-house electric tankless. About $600 unit, $1,400 installed.

Right buyer: 1-bath warm-climate primary residence wanting Bosch engineering over volume electric tankless brands at this capacity. For most residential whole-house applications, the EcoSmart ECO 18 delivers better whole-house performance at similar price.
