Claims of up to 20% more hot-water availability and faster heating are not accompanied by measurement conditions. Confirm installation suitability and expected supply with a qualified installer, particularly given the listed 220 Volts (AC) specification.

Customer feedback reports that the heater works well for washing dishes, heats quickly and is appreciated for its compact size. One customer says it supplied enough hot water for two people to shower, but that report does not establish a general capacity for showers. The comments are relevant to light household use, though the specified 10-litre tank remains the clearer guide to how much stored water is available. Ratings are mostly five-star, with some three- and one-star ratings, so experiences are not uniformly positive.

Positive themes

Feedback describes quick heating and useful performance for dishwashing.
Customers appreciate the compact size.

Frequently asked questions

What is the capacity of this COMFEE' heater?

The listing specifies a 10-litre storage capacity. This is a modest reserve, so suitability depends on how much hot water is needed between reheating periods.

What power and voltage are listed?

The listing gives 2000 watts and 220 Volts (AC), with a corded-electric power configuration. Confirm the supply and installation requirements with a qualified installer.

What are its dimensions and mounting type?

The listed dimensions are 32.4W x 32.4H centimetres, with a depth of 30 centimetres. Wall mounting is listed, and the product is described as intended for undersink use.

How well does it retain heat?

The listing is inconsistent: one claim says the water temperature falls by 10°C over 12 hours, while another says 14.8°C over 12 hours. The source does not explain the different conditions.
