Bosch Tronic Heat 3000 US3 1.5 GPM Electric Tankless Review
The Bosch Tronic Heat 3000 US3 is a 1.5 GPM electric tankless water heater designed for small single-fixture installations. The US3 model sits below the larger US7 in Bosch's electric tankless line.
Specs: 7.5 kW, single 40-amp double-pole breaker at 240V, 1.5 GPM at a 35°F rise. Stainless steel heat exchanger. German-engineered with smooth temperature modulation.
The 1.5 GPM capacity is sized for handwash + small shower applications in single-fixture installs. Below the typical whole-house electric tankless capacity, above standard point-of-use units.
About $400 unit, $700-$900 installed. Right buyer: single-fixture install with moderate demand (small bathroom shower in warm climate). For most residential whole-house applications, the EcoSmart ECO 11 or Rheem RTEX-13 deliver better whole-house performance at similar price.
