Neat and compact
The unit works well and is beat and unibtrusive. I have it set to produce a temperature if 40°C at the handbasin. This is a comfortable temperature for my young grandchildren. The installation instructions were clear. The unit requires 4mm cable from the distribution box and a 32 Amp breaker and double pole switch for safety and isolation purposes. I am very pleased with it. Please note it is not designed to produce hot water for a shower but is great for a handbasin where a small amount of hot water is needed.

Disappointing
It a shame because it’s very easy to fit and it looks neat .But it just doesn’t work . Can’t get any sort of temperature in the water unless you reduce the flow to an absolute trickle . Maybe mine was faulty? I sent it back and got a refund

Small to fit in any small unit but not powerful for mixed water
Can't warm water more than 20 degree C on full open tap but with less pressure the temperature can raise to 25C but the made is quite impact and small, easy to install and looking nice for price.

Good product, good value and good result !
I was very impressed with this and now wonder why something like this hasn't been offered before. I am considering buying another one or two for sinks in my house which require the hot water to be run for a short while before any warmth comes through. I should also save on my heating bills as the boiler won't be stopping and starting to produce small amounts of hot water which will mostly lie in the pipes, cool off and be wasted.

excellent water heater for smaller requirements.
once installed worked exactly as advertised. ideal for uses where 10L of water is enough. (don't try to fill a bath with it!). perfect for hand washing or a sink full of reasonably hot water. also has an eco setting which appears to save power when it's not in use. finally, unlike instant water heaters you get full water flow at temperature. great.

I wouldn't waste your time and money
So, it sounded like a good idea and simple fix for no hot water in the location of a new utility sink. Its 5.5kw so should be able to heat the water sufficiently considering the flow rate you get from other over sink hand instantaneous hand washers, that are around 3kw. To get the kind of heat you need from this, for example 40degrees, the water had to be dribbling out of the tap, so much so, the heater would then intermittently turn off as the flow was so little it though the tap was off... the air temp is around 10 degrees so nothing particularly low. It might be sufficient in the summer, but defo not the winter by any stretch. It will just have to be a storage tank which is slightly annoying as the sink is occasional use so will be a little wasteful for the time the water is being heated but not used. long story short. its not fit for purpose.

Good for heating a small sink of water
I liked the fact that it had universal mounting and LED temperature display. However do not expect too much from it as it does not heat very well on full flow

Excellent bit of kit.
Very easy to install. Whilst you do not need to install a pressure reducing valve i would say it's a worthwhile expense. You wont need a plumber necessarily. I had to return one after 6 weeks of operation but it was promptly replaced by their customer services. Time will tell if they last but either way i think its relatively good value for money. Thank you Michelle .

This tankless water heater offers excellent quality at an exceptional price. Installation was simple, and it has performed flawlessly from day one. What stands out most is the noticeable reduction in my electricity bill since switching to this system. In just two years, it has more than paid for itself. I took a chance moving from a traditional water heater to a tankless model, but it turned out to be one of the best decisions I’ve made.

Meine Küchenlieferung hat sich leider verzögert, daher konnte ich das Gerät erst jetzt installieren. Ablauf der Rückgabefrist war 06/2019. Jetzt stellt sich heraus, dass das Gerät nicht zum Inbetriebnehmen ist. Anzeige zeigt nichts an. nur LeuchtLED erscheinen. Gerät heizt auch nicht. Fazit: unbrauchbar.

We installed the 27KW water heater in a 3 season cottage. It required a significant upgrade to the electricity load in the house. Minimum 200 amp. It draws 115 amps when operating at maximum. It provides all the hot water you want in a 4 bed 2 bath house. We also have an outdoor shower. There can be as many as 8 people in the house at a given time as a seasonal rental. No complaints about the hot water this year. We had installed a smaller unit in an apartment elsewhere and it was an 11kw system. Not enough to fill a tub. Shower was fine. May need to upgrade that one. We are on Prince Edward Island and this unit should work fine year round with our well. I was warned by our electrician that the electric bill might be high. We have been monitoring that and it is fine and within what we would expect. Very happy with the unit. Our property rents from time to time and we can set the water temperature so nobody gets scalded by the hot water. Very handy. Recommended.
