What is it ?

An instant boil kettle is a type of fast boiling kettle that can dispense boiling water within a few seconds of being switched on.  Some styles dispense an exact measured quantity, while others (like the featured kettle) allow a variable amount of water to be dispensed.

How does it work ?

Very simply, an instant kettle will boil just the amount of water required and no more.
To achieve this in a normal speed boil or conventional kettle you would start with a completely empty kettle and then add exactly the cold water you wanted boiling and then turn the kettle on to boil. After a while your kettle would boil and you would have your cup of hot water.

An instant kettle does the same process, but saves the effort of emptying and measuring water into a kettle, by having a cold water reservoir from which to obtain water. Once turned on, the instant kettle will begin to dispense hot water within 5 to 8 seconds through its spout. Cold water is passed over a hidden heating element to produce the hot water for your cuppa. As a simple analogy, a wall mounted power shower box does the same kind of operation, converting cold water to hot water as it passes over a heating element.

What cup size will it pour?

Dependent on the make and model an instant kettle will pour a fixed amount of hot water (usually a cup full) or let you decide how much water to pour.
The fixed volume kettles beg the question, how big is a cup or a "normal" cup? The answer is you will get fixed millilitres of water no matter how big your cup or mug. For some people this is just fine, but others may want a mugful and hope that dispensing 2 cupfuls will fit in their mug. If it doesn't it can cause problems with spillage.
Fortunately, there are instant kettles available that let you decide how much water you want in your cup or mug.
The featured model has a rotating dial on its top and will dispense water for as long as it is left in the On position, or until it reaches the minimum reservoir level (2.5 litres on the featured model). To stop hot water flow, simply turn it anti clockwise to turn it off, working just the same as any normal tap.

How long does it take to pour ?

Although they are described as instant kettles, they cannot dispense hot water within a second, as the heating element needs time to power up and ready itself for the water flow, However, dependent on the initial cold water temperature, the instant kettle will begin dispensing hot water within 5 to 8 seconds into a cup or mug below its spout.
It will continue to dispense hot water at a rate of approximately 500ml per minute.
Generally though, a cup of tea or coffee would be ready within about 25 seconds.

If you really can't wait that long or you need more than a cupful of hot water then you might want to look at a Thermopot.

Is it economical ?

Because it only heats the exact amount of water you need, it is the most economical way of boiling small volumes of water. It generally has a 2500-3000w power output to do this but operates for just seconds to dispense just the water you need.
Most times a household will boil a kettle with whatever water is in it, whether it is all used or not. This is an in efficient use of electricity and a waste of money. The instant kettle boils just what is required and no more, saving both time and money.

Safety feature

Most instant kettles have an auto cut-off to avoid burning out the element when no water is passing through it. In the featured product an LED illuminates GREEN when water is pouring correctly and illuminates RED and switches off dispensing operations when there is no water in the reservoir. 

Is it for me ?

  • If you want the convenience of not waiting for water to boil then yes.
  • If you have difficulty lifting a kettle to pour hot water, then yes.
  • If you want to save some money by boiling only exactly what you need for a cuppa, then yes.
  • If you have a family who are always boiling the kettle, then yes.
  • If you need to replace your kettle and are looking for a great stylish alternative, then yes. It is not much bigger than a normal kettle, so is just a small footprint in your kitchen or office.
