QETTLE 4 Litre Boiler

There’s a reason for the number of good reviews for this product. All the components seem to be of very good quality, and the tap works just as you would expect. There is quite a bit of ‘stuff’ to go in the unit under the sink; the boiler (4l boiler is about 35(h)x 25(d)x 20(w)cm), the water filter, a drain which attaches to your sink waste pipe, and a little battery box which tells you when the filter needs changing. One of the biggest uses of space however is the myriad of flexible pipes which connect all the components. It needs a little thought about what goes where, but easily fits in a single 60cm unit, and it took me about an hour to fit and get the tap working. It’s worth running the water for a few minutes once set up to flush the system through- there was a small amount of gunk with the first bit of filtered water. One other thing to note is that the boiling water comes out somewhat cloudy- this is normal, as it’s just tiny bubbles- they clear if you let it stand for a minute, but looks strange of you’re not expecting it. The filters are significantly cheaper than rival products, which is worth factoring in, although they will still cost you £50/year if you change it as often as they say you should. In operation, the left hand side is a standard mixer tap, the right hand side is either cold filtered water, or if you press the safety button in and rotate away from yourself, boiling water. You can’t vary the temperature of this like a mixer, just the flow rate of the boiling water, which is good as you don’t want it firing out at full speed. Some steam comes out with the water, which can cause it to spit a bit if you pour too fast, although I’ve never scalded myself. The water is definitely boiling when it comes out- my thermometer measured 99.6°C in the flow of water. It will have to last for 20 years to pay for itself in energy savings, but that’s not why I got it- it’s cool and very convenient, so I’m happy, and it looks good, just like a normal tap.

I didn’t expect such a big difference when I switched from my InSinkErator to the Qettle 4‑in‑1, but honestly, it’s night and day. The Qettle feels like a proper step up in both build quality and everyday convenience. The 4L adjustable tank is a standout feature. It heats quickly, holds plenty of water, and the ability to fine‑tune the temperature is something I didn’t realise I needed until I had it. Getting 99°C water straight from the tap is a luxury I now can’t live without—perfect for hot coffee and cooking. Installation was straightforward

My husband wanted this, I wasn’t bothered…however I love it now. Had this about 6 weeks, when we fitted it the handles leaked like crazy. Rang Qettle and they posted our two new valves plus everything we needed to fit them including videos immediately . Took my husband 20min to replace both and no leaks. I’m really impressed with both the customer service and the tap itself. I was worried about the reviews that said it spits but after a day or two of using that stopped and it only does it now if the tank runs out. It’s saving us money as hubby had a tendency to put the kettle on forget it and reheat a few times. Instant boiling water also means no waiting for pans to boil. Can’t recommend enough. Yes there is another great brand out there but it’s £1k dearer for a 4 in 1. Love it love it.

Overall, a good purchase ar the price. We’ve had our Qettle for nearly a month now and it’s been a useful addition to the kitchen - and nice to have reclaimed the counter space where the kettle was. It’s been reliable so far and extremely convenient, and the product is obviously well made. I do have a few minor gripes however. Firstly, the boiling water stream does spit a tiny bit, at angles, meaning on occasion I’ve had very slight droplets of boiling water land on my hand or arm - nothing dangerous or sufficient to do damage, but a stark reminder of the heat this thing generates. Secondly, cups of tea *always* end up with froth on top. The guidance in the instructions / online does warn of this and blames certain types of teabag plus hard water (we’re in a very hard water area), but I’ve tried a few to no avail. It’s just water foam, and is easily removed but isn’t ideal. It is easy to add the teabag to an already-poured mug of boiling water, which doesn’t result in the same effect, but a strange bug in the device nonetheless. Thirdly: the filtered water it produces, whilst tasting lovely, is not particularly cold. This makes perfect sense on the basis that the tank doesn’t have a chiller but keeps the prefiltered water at room temperature, but not something I’d acknowledged before purchase. Thankfully our fridge has a similar function so no issue. Finally - and this isn’t a criticism of the product but a watch-out for buyers nonetheless - the tap mechanism takes a bit of getting used to; it’s not that it isn’t intuitive but it is obviously different to the previous kitchen tap it replaced, and it would be easy to scald oneself by using boiling water as opposed to cold. I’m not particularly reassured by the small safety catch that is supposed to stop this happening, and the product could be a risk if small children are about. All in, however, a very worthwhile purchase and one I wish I’d made years ago.
