 Instant Boiling Water Taps

Sometimes dealing with water problems can be a hassle. We need boiling water but have the problem of waiting too long for a watched kettle to boil. With instant boiling water taps, we can get the boiling water without waiting for it to boil in a kettle. Many people tend to run in to trouble when they need hot water quickly. More often than not, it takes them forever to get their water boiling hot. Most times, people need instant boiling water and don’t have time to wait for it. We also need water that is filtered from chemicals, grime and bacteria that water systems produce, that is why we need instant boiling water taps. Instant water boiling taps can give boiling water we need instantly. It’s also great for when we need to wash dishes quickly, have a quick hot drink. It’s also great when we need instant chilled filtered water to make ice cubes or summer drinks. In addition instant water boiling taps work under the principle of water pressure to provide instant boiling water and filtered water. Installing instant water boiling taps for our home or office makes life much easier when we need boiling hot water quickly.

Instant Boiling Water Taps Versus A Kettle

While having instant water boiling tap installed is great idea – we will be able to make a cup of tea instantly rather than waiting for the kettle to boil, it is normal to think that must use a lot of energy to keep the water at boiling point constantly. Some suppliers of the kit even claim it costs just three pence a day to have the boiling water at hand. If this is true, how does that compare with the cost of boiling a kettle? The fact is instant water boiling taps aren’t cheap. On the average leaving labour cost aside, instant water boiling taps cost around £1,200 to £1,400. They come as heavily insulated tanks, which range from three litres to twelve litres, sit under the kitchen sink and connect to the water supply, while being heated electrically. The water is purified when it passes through the filter, and is dispensed through the tap.

It is claimed that the cost of using instant water boiling tap is one penny per litre delivered, or approximately three pence a day. The cost of boiling a full kettle (which typically holds 1.5 litres) is around 2.5p per boil, according to npower. This would suggest that instant water boiling tap could save users a significant sum, particularly those who regularly boil their kettle. Some even argue that the instant water boiling tap would also save home owners and businesses a significant amount of water, 100 litres of water a year, because users only dispense as much water as they need, while many waste water when using a kettle because they overfill it, re-boil it, and because leftover water is often poured down the drain.

However according to published review of the independent energy consultants, calculated that the difference in savings are in fact minimal. According to the consultants, the amount of energy it would take to make six 250ml cups of tea or coffee on six separate occasions with a kettle (typical minimum kettle fill of 500ml) would cost 5.46p per 24 hours. According to these calculations: 3kW x 84 seconds x six = 0.42 kWh. 0.42 kWh x 13p/kWh = 5.46p.

When using the instant water boiling tap, the amount of energy it would take to heat 1.5 litres (six 250ml cups) from 15C to 110C would be 4181 x 95 x 1.5 x 2.777778e-7 = 0.1655 kWh. To keep the water hot over 24 hours the amount of energy used would be 0.01kW x 24h = 0.24 kWh. So, the total energy used would be 0.1655 kWh + 0.24 kWh = 0.4055 kWh. This is equal to 5.27p per 24 hours (0.4055 kWh x 13p/kWh).

Although using the instant water boiling tap is slightly cheaper, with a basic instant water boiling tap costing around £1,200 it would take several years before any savings are actually made.

Also Kettles waste energy for a number of reasons – design issues such as over-boiling and heat loss through the body of the kettle can result in significant amount of energy used being lost. Even more significant is the typical minimum fill level of 500ml which can mean we end up boiling twice as much water as necessary if we only want to make one 250ml mug of tea or coffee.
Instant water boiling tap is designed with a vacuum-type insulation to minimise heat loss, however if left on standby constantly the amount of heat leaking out is comparable to that which can be wasted using a kettle. For instance, if we boil water for one 250ml cup six times a day then the savings over using a kettle will only amount to 0.2p per day. If we switch the instant water boiling tap off overnight, are a heavy user or are one of the those people who have a habit of overfilling the kettle then we may save an additional penny a day, however even this will not recoup the instant water boiling tap’s purchase and installation costs.


Instant boiling water taps are cheaper than using a kettle, much faster and more convenient.  The installation costs would deter most of the general public. However, those with busy lives, and or a high-end kitchen will really benefit from having an instant boiling water tap – much to the envy of their friends.
