It is installed easily and quickly in the bathroom or kitchen (application only to one supply). It is easy to use or maintain and serves daily needs such as washing hands, dishes, clothes, or other functions.
It is equipped with a built-in digital display that shows you the water temperature and also gives you the option to select it yourself.
The instant water heater is a type of water heater that heats water in real-time. It only heats the water that passes through it at that moment. There is no hot water storage tank. This has many advantages, such as energy savings, since only the water that is used is heated, and longer lifespan, as there is no water tank and no accumulation of salts on the resistance and other components.
It operates with electricity and is single-phase.
The instant water heater has a cold water inlet pipe, which passes through the resistance, heats up, and exits through the hot water outlet pipe. A necessary condition for the instant water heater to initially function is the pressure of the incoming cold water should not be too low.
The water temperature is regulated by a thermostat, so it does not exceed a maximum value. The temperatures reached by the hot water are preset so that one can use the hot water directly, without the need to mix it with cold water.
The maximum temperature that can be reached for hot water production is 60 °C, while the maximum water flow rate reaches up to 8 liters per minute. Indicatively, 38-42 °C is the standard for shower use.
Specifications are collected from official manufacturer websites. Please verify the specifications before proceeding with your final purchase. If you notice any problem you can report it here.
I have it for two months and it works perfectly! I installed it without any difficulty. Let's see how it will work in the winter.......
I bought two more of them to have them as backup for both houses.
Until today - 30/12/22 - I take a normal shower... you just need to reduce the water flow in order for it to heat up quickly. So its use is satisfactory. I recommend it as a good and economical solution.
After a year and a half of use, (27-3-24) I can say that it has fully met my needs.... even during heavy winter conditions!
Poor quality materials. All plastic. Two rubber bands were missing. The connection between the heater and the phone broke when tightened, and it was impossible to find a pipe of the same size, neither 1/2'' nor 3/4''. After some tinkering and improvisation, the hot water pipe opened (tore) during the second use. However, while it was working, it heated the water.
Attention, very poor construction, it broke in my son's hands.
I got them for testing, I say for the money that whatever happens it doesn't matter, it's worth the money, certainly as a construction it's not the best and I was worried about the comments that it might explode but everything is fine, the connectors when you connect them for the first time need to be handled carefully because they are plastic and the pipe that connects to the regular phone shower needs a regular spiral because its own is plastic and small and besides that I was worried about the pressure, so you estimate about 5€ for that, the installation was done by me an amateur ((handyman)) whatever my hands can do, I can say that after 6 months the choice is excellent if you pay attention to how to install it and how to use it,,, very hot water needs to flow slowly,, in my case I have the flow on full and you get burned from how hot it brings, I also have solar in 2 houses at the same time and it brings me the tiniest lukewarm in winter and I run it parallel with the instant heater, I AM SAVED,, 6 MONTHS WITHOUT USING A WATER HEATER...... IT'S WORTH THE MONEY
With this bathroom water heater, you can take a bath much more easily than you would with another one that is a faucet with a shower due to the difference in pressure, regardless of what the devices say! What I don't like is that with all small-sized water heaters, when the flow is greater, cold water starts to come because it can't heat up at a high flow (logical due to size) and nothing else. Other than that, with this one, taking a bath is easier than with others, but not like with the water heater where you control the flow independently of the hot water! I clarify this because some may get confused!
For me, in my opinion, it is not suitable neither for winter nor for summer. In winter, you open it as little as possible and it cannot exceed 32 degrees, and in summer you open it all the way and it does not drop below 45 degrees. The bathroom as a space usually has a temperature of 28 degrees before it is used, winter - summer. In addition, it is very poorly constructed and the water inlet and outlet, as well as the phone cord, are very bad. Apart from being quite short, you cannot replace it due to the threading in the screwing that does not fit with any other and requires a patent
I bought the product for use with a bidet phone. The connection to the phone is made in unrelated, rather mediocre turns and I had to improvise. The water regulator broke in a month and I put in a valve. At some point, it turned on by itself and luckily I happened to be nearby and unplugged it. I opened it up and connected the contacts, so I operate it with a power switch. While it works, the water temperature is not stable even with constant pressure. It is sufficient for the bidet, but I don't think it's suitable for bathing. I should note that I bought it because it was the only one I found in 3.5kW that was acceptable for short-term use with a 1.5mm cable I had in the installation, otherwise I would have bought something of higher quality.
WARNING!!! It blew up in the hands of the electrician....
Very good. It provides hot water... but what they don't mention is that the temperature adjustment depends on the water flow. In other words, in order to take a hot bath (above 40 degrees), you will have to greatly reduce the amount of water. The temperature regulator... essentially functions as a water flow regulator. Overall, though, I am very satisfied. My family uses it due to a malfunction in our solar water heater.
In winter, it won't be cold even in the southern suburbs of Athens where the water is warmer
Stay away!!! It is dangerous!
It never worked properly, it doesn't adjust the water temperature but the pressure, it tripped the circuit breaker (the washing machine works fine on the same outlet...)
I returned it and got my money back immediately.
Very good for its price, I tried it in winter and it performs great, hot water instantly in all cases
The water cannot be heated above 32 degrees... and we still have hot days. What will it do in the cold? You can't take a bath with this temperature. Useless purchase.
The water temperature depends on its flow. Quite cheap. I installed it in an outdoor shower. It does its job
Tested only in the summer so far, but with enough cold tap water supply. In the few days that I have used it, it works exceptionally well. It requires a little attention because the hydraulic connections are plastic. For €30, I don't think there is anything better.
For summer when the demands are low, it raises the temperature a few degrees which is sufficient. For winter, I consider it inadequate to take a bath. Otherwise, it seems to have good construction.
