Bosch ES2.5 Tronic 3000 T 2.5-Gallon Mini-Tank Electric Water Heater – Under-Sink, 120V

On-Demand Hot Water, Right Where You Need It

The Bosch ES2.5 Tronic 3000 T Electric Water Heater brings hot water to the point of use with a compact 2.5-gallon mini-tank. Perfect for under-sink placement, it provides hot water exactly when and where you need it. The unit ships with a long 36–37 inch cord for easy plug-in installation to a standard 120-volt outlet, or it can be wired inline with a larger hot water source for on-demand use.

Built for durability and efficiency, the glass-lined tank minimizes heat loss while resisting wear over time. The heater’s performance is enhanced by a 98% thermal efficiency rating, helping you get hot water fast with minimal energy waste. An external dial lets you fine-tune the temperature, while the temperature-and-pressure relief valve adds a layer of safety during operation. Its sleek exterior and compact footprint (13.75 W x 13.75 H x 10.75 D inches) make it a discreet addition to most rooms when mounted at the sink.

Key Benefits in Real-Life Scenarios

Imagine high-demand moments in tight spaces—a kitchen refresh, a bar sink, a workshop, or a compact apartment where full-size heaters aren’t practical. The ES2.5 delivers hot water quickly to one or two sinks at a time, reducing wait times and keeping daily tasks moving smoothly. Its flexible installation options enable shelf, wall, or floor mounting, so you can position it for optimal accessibility without crowding your space.

Installation, Safety, and Style

Mounting versatility is a standout feature: shelf, wall, or floor mounting is supported by a included bracket, making it easy to place the unit in a visible location that still blends with décor. The glass-lined tank design contributes to long-term durability, while a dedicated external dial enables straightforward temperature adjustments. A reliable temperature-and-pressure relief valve supports safe operation, and the compact design keeps cables and pipes neatly contained.
