Standard electric kettle vs Instant hot water tap
Side-by-side comparison, when-to-use-each guide, and instant conversion. Reviewed for 2026.
Quick answer: Standard kettle: £15-80, boils 2-3 mins, uses exactly what's needed (if you don't overfill). Instant hot water tap (Quooker, Grohe Blue): £800-2,000 installed, 97-98°C water on demand, eliminates kettle boiling, insulated tank uses ~10p/day standby. For tea-drinking UK households: the tap is more convenient but the payback period is 5-8 years.

Frequently asked
?
Does an instant hot water tap actually save energy?
No — it typically uses slightly more due to standby heat loss from the insulated tank. The advantage is convenience and speed, not energy saving. Modern Quooker tanks are well-insulated but still lose some heat constantly.
?
What temperature is needed for tea?
Green tea: 70-80°C. White tea: 65-75°C. Black tea, English Breakfast, Earl Grey: 95-100°C. Instant hot water taps at 98°C are ideal for black tea. If you drink green or white tea, a temperature-controlled kettle (£30-80) may actually be more useful.
