Instant Electric Water Heaters

Explore compact tankless electric water heaters that warm water on demand rather than storing it in a cylinder. These units may suit sink and other small hot-water applications, depending on the model and required flow.

Choose by electrical load and water flow: check the unit's kW power rating, compatible water pressure, expected temperature rise and installation instructions. Hot-water output depends on the incoming water temperature and flow rate, so a compact heater will not provide unlimited hot water at every flow.

Some electric water heaters require a dedicated high-current circuit and suitable plumbing. Have the installation assessed and completed by appropriately qualified professionals. For room heating instead, view electric wall heaters.
