Most people will be charged per unit of electricity so you might be charged 12p per kwh used. So if you had something that uses 1kw, it would need to be on for a full hour in order to use up 1kwh. The cost of this would be 12p. If you had a kettle that uses 2kw then in one hour it would use up 2kwh. But Chudy and Grase are examining how they can regulate the temperature so that it switches off reacting to various fluids; turning off at, for instance, 40C with baby food, or at 70C with green tea.
That ability to heat water to a specific level for green tea — after which the brew becomes bitter — is one unexpected use, which has prompted interest in the product.
Hotels have also inquired about it because of it being a discreet appliance for rooms. In an ideal scenario their invention would be in the shops by the end of summer — depending on their progress towards the final product and how they navigate the regulatory obstacles in the meantime. So far, they have been financed by friends and family but a crowdfunding campaign is expected for the next stages.
Watch how the sellers of conventional kettles respond to this threat to their dominant market position. For a starter, I bet it will prove very, very difficult to be able to find these energy saving kettles in the stores. You are commenting using your WordPress.

My kettle input is W My microwave input is W So using ml at the same starting temperatures.
I put the microwave water in a small plastic sealed container. I also take the glass dish out of the microwave. I started the microwave on high for 60 secs, and then the kettle at 30 secs. At the end the water was approx the same temperature.
I am not able to test the gas hob as I have no way of measuring the amount of gas used. How would anyone do that? The energy losses in a microwave are from heat generated from the magnetron, the AC power transformer, the light, the motor drive for the turntable, the control circuitry and the fan to dissipate aforementioned heat. John Shaw, Buxted England In my test at home, the microwave required W input for seconds, but the electric kettle required W for seconds to produce boiling water for a cup of tea.
In my case the electric kettle is less efficient for making a single cup which is my primary use. This is because the kettle requires a minimum fill of ml of water and I only need around ml.
Any costing refers to NSW values. To boil 1 litre of water in a Circulon kettle on an Ariston gas cooktop took 5mins 5secs and used 0.
COST 0. To boil 1 litre of water in a Russell Hobbs electric jug took 2mins 45secs and used 0. Although Shoulder period electricity is only marginally more expensive than gas a working couple would be mainly boiling their water during the Peak period.
Barry Shearman, Woongarrah Australia Kettle on top of wood burner if burner on anyway. Another tip with electrics, don't keep re boiling the kettle if it goes off the boil. X Neal, Hereford, England My priority for boiling a kettle is how little noise it makes, not how fast it boils or how efficient it is. Gas wins hands down. Most electrical appliances are built to achieve a low selling price, which in most cases means a high noise level.
A gas kettle is so quiet, why is everyone in so much of a hurry, chill out, relax and have a cup of tea! In part, this will depend on how much energy your kettle and microwave use. The average kettle uses between 1, — 3, watts. A modern microwave by comparison uses around — watts. How long it takes either to boil water will depend partly on how much water you are heating.
However, both take on average minutes. The price per boil will depend in part on your tariff but costs will be around pence to boil a full kettle, compared to pence using a microwave. A word of warning though, the kettle has evolved over the years into a very safe appliance.
The microwave by comparison relies on your common sense. Energy efficiency should be sought everywhere, from the kitchen to the living room. Make sure you TV is also energy efficient. So, in the end, getting an eco kettle is a small step in the right direction to reduce your personal energy consumption.
Ensuring your kettle offers functions such as cup measurements, a keep warm function and an automatic shut off are easy wins. However, a word of warning.
