Klugit — Turning any water heater into a smart appliance

Klugit is a startup on a mission to put families on the frontline of a clean-energy future — saving, storing and renewing energy at home.

With this project, Klugit wanted an easy-to-install retrofit that turns any electric water heater into a smart appliance: one that learns a household's habits and stops paying to heat water nobody is about to use.

Unboxing the retrofit kit — packaging made from ocean plastic.

Project stages

  1. 01

    Problem

    Every electric water heater wastes energy and money. Right after the last shower of the day, the boiler starts heating up again anyway — with nobody left to use the hot water. That waste can add up to 1.5 kWh a day.

  2. 02

    Hypothesis

    Is it possible to save energy in water heaters by applying artificial-intelligence mechanisms to an ordinary boiler?

  3. 03

    Proof of concept

    To find the technology needed to validate the concept, we built an electronics box we called KLU — the Klugit Lab Unit.

    In just two months we were able to prove the energy-saving potential of the solution in the field.

  4. 04

    Prototype

    At this stage we worked two development branches in parallel: industrial design and electronics engineering, so the enclosure and the intelligence inside it could mature together.

  5. 05

    Pilot project

    So far we've delivered 30+ units to home users across three pilot projects.

    Those households saved more than €130 a year on average, while shifting electricity consumption away from fossil-fuel-heavy periods on the grid.
