The standby heat loss, or energy that the Hotspot Titanium uses even when no water is drawn, is approximately 25 Watt for an 8-litre water heater and approximately 16 Watt for a 4-litre water heater. If you think about a typical in-home wireless router, the HotSpot Titanium is equivalent when it comes to energy usage.
It costs an estimate of 9 pence a day for an 8-litre and 6 pence a day for a 4-litre heater (assumed 15 pence / kWh) Remember, this depends on the energy supplier and rates, among other factors.
The below table shows the difference between a conventional kettle and Hotspot Titanium 4 and 8-litre. We have considered the amount of energy it would take to make six 250ml mugs of tea or coffee on six separate occasions with a kettle (partial kettle-fill of 500ml). The cost equated to £0.063p per 24 hours – this based on 3kW Kettle x 84 seconds to boil = 0.07 kWh. With an assumed cost of 15p/kWh x 0.07 kWh = £0.011p.
