How much electricity does a boiling water tap use? To maintain water at a hot temperature, a hot water top will use around 10 watts of energy. In comparison, the average kettle uses between 2-3 kilowatts every time you switch it on.
Boiling taps are very cheap to run, but it's important to factor in the upfront cost and installation price. In the short-term, it's cheaper to buy a kettle than to purchase and install a boiling water tap, but keep in mind that they will save money on your energy bills in the long run.
Though this may come as a surprise, Expert Energy have actually estimated that an instant boiling tap can use up to 50% less energy that traditional kettles. 67% of people overfill their kettle with every use which leads to an astronomical 3500 tonnes of waste CO2 everyday.
It is worth pointing out that hot water taps are more energy efficient and could ultimately work out cheaper, depending on how much you boil the kettle on an average day. If you only make the occasional cup of tea then it will be far cheaper to stick to your trusty kettle.
For example, one 3kW kettle can boil a litre in just over 2 minutes, while another may take as long as 2 minutes 30 seconds.
When you take into account the cost of gas and electricity, we found that it's cheaper to boil water on a gas hob than in an electric kettle.
An induction stove or hot plate is about 85 percent efficient. It creates an electromagnetic current directly in a pot to generate heat, losing very little to the air.
There's no need to turn off your boiling water tap at night, but it will help bring down your energy consumption. If you want to keep your energy usage and bill as low as possible, turn off your boiling water tap at night or while you are out at work, and turn it off when you go away on holiday too.
Experts at Uswitch.com have explained how the cheapest way to boil a cup of tea is by using a covered pan on a gas hob, instead of depending on your usual kettle.
The added convenience of a boiling water tap is beneficial too. If you're a tea & coffee lover, there's no more waiting around for the kettle to boil. Or if you're waiting for your water in a pan to boil, wait no more with instant boiling water straight from the tap.
Power usage – Kettles
The average kettle is between 2 and 3 kilowatts (kw). The electricity that you use in your home is measures in kilowatt hours (kWh) which is the number of kilowatts used per hour. Most people will be charged per unit of electricity so you might be charged 12p per kwh used.
Repeatedly boiling a kettle wastes time and energy but is better for low usage. In comparison, a hot water dispenser is a far more energy-efficient and cost-effective way to get near-boiling water over an extended period and is a much better option for staff numbers of 10+.
An electric stove requires more energy and time to heat up, thus it takes longer to heat the water inside the kettle. However, an electric stove is more efficient in delivering energy to the kettle.
To maintain water at a hot temperature, a hot water top will use around 10 watts of energy. In comparison, the average kettle uses between 2-3 kilowatts every time you switch it on.
Like any filter, those on your boiling water tap will need to be changed to help keep your tank limescale free. Manufacturers will recommend you change the filter on your boiling water tap every 6 months, but this number will vary depending on the tap.
If only one cup of boiling water is drawn from the tap, the tank will heat back up to the maximum temperature in under a minute. If the entire amount is drawn it normally takes 4 minutes to get back to maximum temperature. From new or being turned off allow 7-8 minutes.
Although kettles use less energy overall, the differing prices of electricity and gas meant the hob worked out cheaper, the Mirror reported. The self-described academic said: "If you're looking for an energy saving, go for the electric kettle. If you're looking for a cost saving, go for the hob."
For most households, a solar hot water system can be the most efficient and cheapest to run. If that's not an option, here are other suggestions. Small household (1–2 people): Continuous flow hot water system (gas or electric) or small gas storage hot water system.
The energy experts at Uswitch.com have looked into this and have found that it's much cheaper to boil hot water for tea using a covered pan on a gas hob. They also found that using a microwave is cheaper than using a kettle as well.
Bring the clear water to a rolling boil for 1 minute (at elevations above 6,500 feet, boil for 3 minutes). Let the boiled water cool. Store the boiled water in clean sanitized containers with tight covers.
The difference, unsurprisingly, is the temperature dispensed by the taps. A boiling water tap dispenses water at 100°C. A near-boiling or steaming hot tap dispenses water a shade below – this varies by manufacturer, but our own steaming hot water taps can be set to dispense anywhere between 88°C and 98°C.
So, depending on usage, you should easily get up to two years, hassle-free, efficient, and money-saving use from your hot water dispenser, while we change the filter for you every 12 months.
An induction stove or hot plate is about 85 percent efficient. It creates an electromagnetic current directly in a pot to generate heat, losing very little to the air.

Disadvantages of Boiling Water
Boiling water can only remove bacteria, meaning it will not remove harmful substances such as chlorine and heavy metals such as lead from tap water. Boiling tap water with lead actually concentrates this contaminant making it more dangerous than if left alone.
