Boiling water tap energy consumption – everything you need to know
Introduction
A boiling water tap provides hot water in one motion, but what does that mean in terms of energy consumption? We compare two popular options, Quooker and Unito, and show how much energy they actually use.
How does it work and what does it cost in energy?
Both taps have an insulated boiler that keeps water hot in standby mode, and then uses extra energy when you draw water. Well-insulated systems minimize heat loss and therefore minimize operating costs.
Comparison table: Quooker vs Unito (standby & drawing water)
What does experience show?
-
On a forum, a user reports that the consumption of a Quooker is around 240 Wh per day, so approx. 88 kWh per year.
-
Other sources describe a Quooker as “as energy-efficient as an energy-saving light bulb,” which points to low daily consumption.
-
According to a British analysis, the annual energy costs of a Quooker are lower than those of an electric kettle, despite the high purchase price.
What does this mean for you?
-
Standby consumption: Unito uses significantly less (2.5 W vs 10 W for Quooker).
-
Drawing water: While both models release a large amount of power temporarily – comparable to an electric kettle – since you draw exactly what you need, waste is limited.
-
Annual consumption: Quooker reports approximately 511 kWh per year (standby + drawing), while practical measurements point to much lower consumption (~88 kWh/year).
-
Costs: At €0.30/kWh, this comes down to approx. €25–€150/year, depending on your usage and which figure you follow.
Conclusion
-
Unito scores better on standby thanks to an extremely low consumption of just 2.5 W.
-
Quooker is robust, well-known, and popular. Although Quooker states it consumes approx. 511 kWh/year, user experiences point to much lower actual values.
-
For households that frequently draw hot water, the difference in standby consumption can lead to nice energy savings — especially with Unito.
Tip: If you are purely looking for the most energy-efficient performance possible, it pays to choose a model with low standby consumption and efficient insulation.
