🚰 Water Heater System

Electric Water Heater

An electric water heater heats water using an immersed resistance heating element powered by mains electricity. Available in storage-tank and tankless forms, it is valued for simple installation, no combustion or flue, and near-100% point-of-use conversion of electricity to heat.

⚠️ Note: Requires a temperature/pressure relief valve and proper electrical protection (correctly rated circuit and grounding); confirm ratings against the datasheet and local code.

Typical specification

PropertyTypical value
Energy sourceElectricity (mains)
TypeStorage-tank or tankless/instantaneous
Capacity rangeStorage: ~10–500 L typical; tankless rated by flow/kW
Power/rating~1.5–5 kW residential storage; higher for tankless (varies)
EfficiencyNear 100% at point of use (resistance); confirm per datasheet
SafetyThermostat, high-limit cutout, pressure/temperature relief valve
StandardPer destination market (e.g. IEC/UL/CE) — confirm against datasheet

Indicative / typical values for planning — actual products vary by manufacturer and standard. Confirm the final spec sheet before ordering; we do not publish fixed prices, request a quote for current offers.

Applications

Suited to homes, apartments, and light commercial settings where gas is unavailable or a simple, flue-free installation is preferred. Tankless models fit point-of-use applications like a single bathroom or kitchen.

FAQ

Are electric water heaters energy efficient?
At the point of use, electric resistance heating converts nearly all input electricity to heat, so it is highly efficient locally. Overall running cost depends on electricity price and standby losses; a heat pump water heater uses far less electricity for the same output.
Does an electric water heater need a pressure relief valve?
Yes. Storage-type electric water heaters should be fitted with a temperature and pressure relief (T&P) valve to safely release excess pressure. Always follow local code and the manufacturer's datasheet.
