- Using an energy calculating plug to see how much energy to boil a litre of water by different methods. Microwave a bit inconclusive, the lower heating power made the boiling less obvious.
Good video, however, you may have missed something; you are boiling water in a kettle with a lid, Vs a pan with an open top, this will impact the boiling time, due to pressure losses. An induction hob is more efficient and quicker than a kettle (85% Vs 80% approx.) so in theory should be quicker and cheaper than a kettle. I have performed this test with a hob top kettle Vs an electric kettle and the induction hob used less energy in my experiment.
The pan wasn't open....he put the lid on.
I stopped using my electric kettle whern I got my induction hob.
Turns out, the kettle uses a little bit less power but I dont know if that is enough to make any actual difference.
They are almost identical so, the kettle will remain in the pantry.
Thanks, that was the exact experiment I was looking for...
Microwaves dont really work with non polar solvents btw. Time to boil water in a microwave should depend on the amount of dissolved salts.
Just a side note.
Awesome test! Just what I was looking for, thanks!
Glad you enjoyed!
I did a similar test some time back except I used a "one cup" type dispenser, and electric "jug" kettle and the microwave. The first was the fastest and most energy efficient followed by the (2.4 kW) electric kettle with the microwave (900 W nominal) taking almost 3 times as long as the fastest and using almost double the amount of energy. I was using 500ml as my test.
The microwave was also difficult to time and made the mug uncomfortably hot to handle.
Excellent video well done for the information
Thank you sir , this is simple but beneficial to everyone...
Glad you enjoyed! Not 100% scientific but hopefully have you an idea of what things consume.
Thanks Simon!
Really depends on the brand used. On the average, induction is usually more power efficient than kettle with microwave lagging behind. There is current technology called inverter microwave where power efficiency could go up to 90%, way better than induction (avg 85%) or kettle (avg 80%).
Thanks!
Thanks for the test. Until we get a smart meter, I've been curious as to which would be the most energy efficient. Disappointed to see You let the induction method boil on for a few seconds past boil point. I bet it would be a lot. Closer to the kettle., if not better. It would be interesting to see if induction specific kettles are worth the money as opposed to a lightweight induction pan.
Thanks again for your effort though. Think I'll stick with my ceramic coated induction jug.
Yes, not 100% scientific! The kettle was going to be the winner as it's going to chuck at least 99.9% of its 3kw into heating the water. Either way the induction did pretty well.
