Decakila Instant Electric Water Heater 7000W KEWH003W

Our review

The Decakila KEWH003W is an instant electric water heater rated at 7000W and designed to run on 220-240V at 50-60Hz. Instead of storing hot water in a tank, it heats water as it flows, which suits bathrooms or kitchens where you want hot water without waiting for a cylinder to recover. Its heating path uses a reinforced nylon cup and SS304 stainless steel, materials chosen for contact with heated water.
Before buying, confirm your supply can handle 7000W. That draw is high, so check your main breaker, wiring gauge and whether your area gets stable voltage; a dedicated circuit is usually wise. Also think about flow rate and incoming water temperature, since instant heaters raise water temperature by a fixed amount rather than to a set tank temperature.
Compared with storage heaters, this type takes up far less wall space and avoids standing losses, but it cannot serve multiple outlets at once the way a large tank can. Compare power ratings, element materials and whether the unit is suited to your climate and plumbing. It is available on Sokonia.
