Brits love a good cuppa. We make around 100 million cups of tea every single day¹, and for most of us, the humble kettle has always been the way we get there. But have you actually stopped to consider whether it’s the best tool for the job? Overfilling it, waiting for it to boil, pouring water at full temperature onto a delicate green tea and wondering why it tastes bitter, sound familiar?
The CASO HW 770 Turbo hot water dispenser was built to solve every one of those frustrations. Here are a few real-world scenarios to demonstrate why, once you’ve made the switch, you’ll never want to switch back to your old kettle again.
"I just want one cup of tea"
This is probably the most relatable scenario of all. You get in from work, you want a brew, and the habit is to fill the kettle, flick the switch, and wait. But most people fill a kettle with far more water than they actually need, simply out of habit. That excess water has to be heated too, which uses more electricity and costs more money, and then you either re-boil it later or tip it away.
The HW 770 only heats exactly what you ask for. With seven preset volumes from 100 ml right up to 400 ml, you select your cup size and that’s all that’s heated. Nothing wasted. The energy saving compared to a traditional kettle is up to 50%. With energy bills front of mind for UK households, that’s a very real and welcome difference.
We’ve all been there. The kettle clicks off and you’re still rummaging for a teabag, washing up a mug, or dealing with something else entirely. By the time you pour, you’ve lost the optimum temperature for your tea.
The HW 770 delivers hot water in just 7 seconds. You press the button when you’re ready, and the water arrives exactly when you need it, at exactly the temperature you’ve set. There’s no standing over it, no timing your workflow around it. It fits around you.
Green tea, white tea and delicate herbal infusions are notoriously sensitive to temperature. Pour water that’s just come off the boil (100°C) onto a green tea and you’ll scorch the leaves, producing a bitter, astringent cup that puts people off the drink entirely.
The HW 770 gives you 13 temperature settings, running from 40°C to 100°C in 5°C increments. Green tea typically wants water around 70 to 80°C. White tea prefers it even cooler. A robust builder’s brew is perfectly happy at a rolling 100°C. Whatever you’re making, you set the exact temperature and the machine does the rest, consistently, every time.
If you’ve got a preferred cup, the Memory button locks in your chosen temperature and volume so your perfect brew is literally one press away each morning.

"Making hot drinks for the whole family is a faff"
Imagine a Sunday morning. One person wants a mug of builder’s tea at full temperature, another wants a green tea, a teenager wants a hot chocolate, and there’s a baby needing warm water for their formula. With a traditional kettle, you’re re-boiling multiple times, having to guess at the correct temperature and trying to cool things down quickly.
The HW 770 handles every single one of those requests from the same machine, simply by adjusting the temperature setting between dispenses.
"I use a lot of hot water in the kitchen, not just for drinks"
The HW 770 isn’t just for making tea and coffee. With a 2.7-litre removable tank and a continuous flow option alongside its preset volumes, it is the perfect tool for a surprisingly wide range of kitchen tasks.
Need boiling water to kick-start a pan of pasta or blanch some vegetables? Dispensing directly from the HW 770 saves the time you’d spend waiting for a hob element or separate kettle. Filling a hot water bottle on a cold winter evening? Set your temperature, hold your bottle under the spout, and you’re done. These are small time savings that, across a busy week, genuinely add up.
"I hate limescale and cleaning appliances"
If you live in a hard water area, as a significant portion of England and Wales does, limescale is a constant issue. It builds up inside kettles, affects the taste of the water and eventually damages the element.
The HW 770 comes with a water filter included as standard. The filter reduces chlorine, pollutants and the minerals that cause limescale, improving both the taste of your drinks and the longevity of the machine itself. There’s also a built-in descaling reminder and cleaning mode, so the machine tells you when it needs attention rather than leaving you to guess.
"I don't have much space on my counter"
At 15 cm wide and 30.5 cm tall, the HW 770 has a compact footprint that doesn’t take up much space and slots neatly into most kitchen layouts. Its stainless steel housing looks smart and purposeful, unlike many alternatives, and the LED touchscreen display is clean and easy to read at a glance. The HW 770 will easily earn its place on the worktop, rather than getting banished to a cupboard after a week.
The bottom line
The CASO HW 770 Turbo hot water dispenser isn’t about replacing the kettle for the sake of it. It’s about recognising that the kettle, for all its reliability, was designed for a different era, one where energy was cheaper, where one-size-fits-all boiling water was enough, and where precision in the kitchen was reserved for professional chefs.
For a household that drinks a variety of hot beverages, values energy efficiency, wants to save time in the mornings and cares about the quality of what ends up in the cup, the HW 770 is a genuinely smarter kettle alternative.

Frequently asked questions
What temperature should green tea be brewed at?
Green tea is best brewed between 70°C and 80°C. Water that has just come off the boil scorches the delicate leaves and produces a bitter, astringent cup. The CASO HW 770 lets you select the exact temperature in 5°C steps, so green tea comes out smooth and balanced every time.
How much energy does a hot water dispenser save compared to a kettle?
Because a hot water dispenser only heats the volume you ask for, rather than whatever water happens to be in the kettle, it can use up to 50% less energy than a traditional kettle. Over a year of daily use, that adds up to a noticeable reduction in your electricity bill.
Can the CASO HW 770 dispense water at baby formula temperature?
Yes. The HW 770 dispenses water as low as 40°C, which is ideal for making baby formula without destroying heat-sensitive nutrients. There’s no need to boil water and then wait for it to cool, or to top it up with cold tap water.
Does the CASO HW 770 protect against limescale?
Yes. The HW 770 ships with a water filter that reduces chlorine, pollutants and the minerals that cause limescale. A built-in descaling reminder also tells you when the machine needs cleaning, so you don’t have to guess.
Is a hot water dispenser a good kettle alternative for a small kitchen?
Yes. At 15 cm wide and 30.5 cm tall, the HW 770 has a smaller footprint than many traditional kettles and the stainless steel finish suits modern kitchens. It replaces the kettle entirely rather than sitting alongside it, so it actually frees up worktop space.
