Product Details

HARIO ECA-3-B Electric Siphon Coffee Maker

HARIO ECA-3-B Electric Siphon Coffee Maker brings the visual brewing process of a traditional siphon to an electric format. Instead of an alcohol lamp or gas flame, its adjustable heater lets users manage heat input and timing. This reduces open-flame risk, but the glass, heater and brewed coffee still become very hot; operate on a stable, heat-resistant surface and follow the current manual.

The upper and lower glass bowls detach from the heater for cleaning. The source describes flame-resistant materials in the appliance body, making it practical where open flames are unsuitable. This does not make the unit fireproof: keep combustible items away, never leave it unattended, and allow all parts to cool before handling or cleaning.

How to Use

Operation of the HARIO ECA-3-B is straightforward: set an appropriate heat level, then adjust it for the coffee and desired brewing time. The heat-resistant glass bowl handles the brewing temperature, while the aluminium plate transfers heat to the lower bowl. Monitor the full cycle, use the supplied handle, and do not touch hot glass or the heating plate. Results vary with the coffee and recipe.

Siphon Brewing Characteristics

Siphon brewing is known for its visible brewing cycle and the control it gives users over heat, contact time and agitation:

A Visible Brewing Process: heating the lower bowl expands the air and water vapour, moving water into the upper bowl for brewing. As the heat is reduced, brewed coffee returns through the filter. Keep hands clear of hot glass and steam.

Heat Control: adjusting the heater changes the brewing temperature and timing. Small changes can affect extraction, so use a repeatable recipe and avoid assuming the indicated heat level is an exact water temperature.

Immersion and Agitation: coffee grounds steep in the upper bowl and can be stirred for more even wetting. Uniform extraction is not automatic; grind, dose, agitation and contact time still need to be managed.

Filtered Cup Profile: siphon brewers may use cloth, paper or a metal filter. Each retains different amounts of sediment and oil, so clarity, body and flavour vary with the chosen filter and recipe.

A Hands-On Ritual: siphon brewing involves several timed steps and rewards careful heat management and stirring. It suits users who enjoy participating in the brewing process.

Together, these characteristics make siphon brewing visually engaging and highly adjustable. Cup quality is not guaranteed and depends on ingredients, setup and technique.

Important Safety Note for HARIO Electric Siphon ECA-3-B:

This product is rated for Japanese mains voltage. Do not connect it directly to Hong Kong or another incompatible supply. Use only a properly earthed, certified step-down transformer with sufficient continuous wattage and the correct plug arrangement. An adaptor alone does not convert voltage. If you are unsure, ask a qualified electrician. Incorrect voltage or an undersized transformer can cause malfunction, electric shock, overheating, fire or permanent damage. Confirm the appliance label, transformer rating and local requirements before use.

Transformer Information and Specifications

SUPER CT-1000 Transformer Details

The SUPER CT-1000 transformer is listed for conversion between 110V and 220V supplies for imported appliances. Compatibility is not universal: confirm direction, input/output voltage, frequency, grounding, plug type and the appliance's continuous power draw before use. The transformer's listed functions include:

• Up to 1000W Listed Output: the source lists support for appliances within the rated load. Do not size a transformer solely to the appliance's headline wattage; allow suitable continuous-load headroom and follow the transformer manufacturer's instructions. Never exceed the rating.
• Protection: the source lists overload protection in the CT-1000. This is a secondary safeguard, not permission to overload the transformer or use an incompatible appliance.
• Design and Size: the listed transformer weighs 8 kg and measures 210mm × 340mm × 140mm. Place it upright on a stable, ventilated, heat-resistant surface with space around it.

Intended Use: the SUPER CT-1000 is listed for compatible imported appliances within its electrical ratings. Check each appliance separately; do not assume that country of origin alone establishes compatibility.

Use Recommendation: switch off and unplug the transformer after use once the connected appliance is safely shut down. Allow it to cool and never cover ventilation openings.
