We have a Breville - about seven years old - bought in a Sainsbury sale and cost £12 - not timed it but boils quite fast and going OK so I won't knock it - only thing I am not keen on is the lime scale which shows up so much as the kettle is black and our water is very hard. I filter the water but still get a line round the edge of the lid etc.
Russell Hobbs, 1.7 litre, 3 min 31.7 secs. But, it is only 2 weeks old so probably working quite well at the moment. It's a lovely sort of purply silver colour too. It was half price in Sainsbury's.
Ours takes as long as it takes to cut up two pouches of cat food, put them down on the mat, fill the cat milk bowl, put that down then wash the knife. (In short, I haven’t a clue but will check in the morning.)
I have a hob kettle. How long it takes to boil depends on how much water is in the kettle, which burner I put it on and how warm the water was when I started.
I was wondering how efficient or otherwise my kettle is. Given that it's twenty years old, its full of water boiling time doesn't seem bad at all when I compare it with newer models. We don't fill it more than necessary most of the time. Timing it to boil at full was for research.
Mine is a Breville 3pint and is between 2 and 3000 Watts. It takes 3:42.88 minutes to switch off, at max. If I put a pint of water in it, It takes less time to boil the same amount of water on my induction hob, using the boost function.
I've just remembered that I took the filter out yonks ago. Was wondering what the Filterline thing was all about, then I remembered ?. In Oxfordshire, where the water was hard, we used a filter jug for all drinking water, including what went in the kettle. Here in Argyll it's soft water and there's never any furring on anything.
Honestly, we seem to get through kettles, and irons, like a dose of salts and have to buy new every 1-2 years. Are we unlucky or are the new ones not very long lasting? Your aged kettle sounds far more efficient, and economical, than the many we have dumped in that time.
