Tomado TWD2503B hot-water dispenser, 2,5 litres and 2200 W: heat only the 200 millilitres

A cup of tea needs about 200 millilitres of water, yet most people fill the kettle to one and a half litres before pressing the switch. The listing for the Tomado TWD2503B names four selectable draw volumes, 150, 200, 300 and 500 millilitres, and that single line is the whole point of the machine. Heating water from 15 to 100 degrees takes roughly 0,099 kilowatt hours per litre, so 1,7 litres costs about 0,168 and 200 millilitres about 0,020. Count the cups you actually drink in a day, multiply that by the difference between those two figures, then multiply by the rate on your energy contract, and the yearly gap takes thirty seconds to work out. The listing will not do that sum for you, because it does not know how full you fill your kettle now.

The machine itself has a 2,5 litre removable reservoir, draws 2200 W, carries a digital display for setting both temperature and volume, and comes with a water filter. The listing shows 4,0 out of five from 269 reviews at 49,99 euro, against a recommended price of 89,99 euro printed on the same page. 269 reviews is a substantial sample and a 4,0 average means this is not a complaint-free appliance, so it is worth five minutes reading which problem keeps recurring in the lower scores before deciding the price is right for you.

It is also worth being plain: if you already boil only what you drink, this machine saves you nothing, the difference above comes to zero, and 49,99 euro buys convenience rather than electricity. The households that genuinely recover money are the ones that fill the kettle to the top and switch it on five or six times a day. It is a countertop appliance too, so the 2,5 litre reservoir and the body together need a fixed spot, unlike a kettle you can push aside.

• The sum: the litres you normally boil minus the litres you actually drink, times 0,099 kilowatt hours, times the number of times a day, times 365, and finally times the rate on your own contract
• The three specifications that decide it: a 2,5 litre removable reservoir, 2200 W, and four draw volumes of 150, 200, 300 and 500 millilitres, with a water filter included
• Who it suits: households that fill the kettle to the top and switch it on five or six times a day; if you already boil a single cup, there is nothing here to recover
• Limits and next step: 4,0 is an average across 269 reviews, so read what the lower scores have in common, and measure the counter space before ordering
