Hot water in seconds, even on the coldest mornings.

Waiting for the tap to run warm is no fun when it's freezing outside. This compact tankless heater warms water as it flows, so you get hot water within seconds with no pre-heating. At just 19 × 15 × 7 cm it fits under a sink or on the wall in a kitchen, bathroom or office. Automatic power regulation keeps the temperature steady between 30 and 55 °C.

Why you'll love it

  • Instant heat: Delivers hot water in seconds with no pre-heating.
  • Only heats on demand: The 3500 W element switches on only while water flows.
  • Space-saving size: 19 × 15 × 7 cm and 1.2 kg, wall-mounted or under the sink.
  • Stable temperature: Automatic regulation holds 30–55 °C consistently.
  • Built-in safety: Overheat protection, leak-resistant design and IPX4 rating.
