Thanks to Inverter technology, it maintains a stable temperature and lower consumption compared to regular instant water heaters as it uses only the necessary power to heat the water to the desired temperature.
Additionally, it is permitted to connect the instant water heater in series with a solar water heater for greater economy.
It is central and can be used either as the main option for heating the water in your home or as a supplementary one. It can provide hot water throughout the house for your daily needs, as long as there are appropriate pipes for the distribution of hot water. This may potentially result in heat and energy losses due to the distance.
It is equipped with a built-in digital display that shows you the water temperature and also gives you the ability 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. This means 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, since 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 operate is that the pressure of the incoming cold water is not too low.
The water temperature is regulated by a thermostat, so it does not exceed a maximum value. The temperatures that the hot water reaches are preset so that one can use the hot water directly, without needing to mix it with cold water.
The maximum temperature it can reach for hot water production is 55 °C, while the maximum water flow rate reaches up to 4 liters per minute. Indicatively, 38-42 °C degrees are 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.
Small and does its job. A couple of times the E5 indicator lit up, but when I checked the manual, it indicated that the water temperature was above 50 degrees. (I live in Cyprus and the water already reaches that temperature from the solar heater, resulting in high temperatures. As far as I understand). Also, when the temperature dropped to 7-9 degrees, it took quite a while and it never reached 37 degrees. I usually take a bath at 40-43 degrees.
Easy to use and easy to install if there is provision. Perfect in terms of maintaining a stable water temperature whether you open the hot or the cold.
I really wonder about those who are satisfied with this thing. I bought it for professional use in the laundry. In order to have a satisfactory temperature, the flow must be very low. Not a shower, not even enough to wash your hands... A dropper. And I should mention that it is connected to the boiler so it doesn't pass the cold water from the network. The most wasted money I have ever spent.
I use it for showers - now that it's spring, it reaches 40 degrees in a few seconds, very good!
First time I saw and used it in an Airbnb apartment and found it interesting. Immediately after, I did some research and decided to get it for my home. The apartment has solar and separate electric water heater for the winter.
After two weeks of use, several of which were without sunlight, I can simply say that I wonder why there are still electric water heaters. It is simply perfect. Stable temperature and very satisfactory flow. I operate it at 3.5 kW. I installed it myself, taking advantage of the existing water heater line, inserting a switch. I believe that if the water in some area is very cold, then maybe you need to operate it at 7 kW, if necessary, an electrician should intervene to pull a thicker cable.
I read many reviews and got confused. So I decided to take the risk and buy it. The machine does what the manufacturer says and does it correctly. If the water input is 15 - 20 degrees, it easily reaches 40 degrees. As the temperature drops, you need to reduce the water flow rate in order for it to have enough time to heat up. It has a special valve that regulates the flow. I followed a hybrid connection, meaning it takes water from the solar panel, so in the winter when the solar panel doesn't heat the water sufficiently, I utilize the lukewarm water without needing to turn on the solar panel's resistance and heat it to the desired temperature of 160 liters, which is the entire tank's water. I use it during the winter in low power mode because the supply cables are thin, and until December, when I have tested it, it's okay. Finally, I would like to advise those who are considering buying it to measure the temperature of the water they will use. If the water is below 15 degrees and you want to raise it to 40 degrees, a single-phase water heater won't do, you need either a three-phase or a gas water heater.
Very good water heater! Even on the lowest setting of 3.5kw, it heats the water in seconds and maintains it at the temperature you choose!
Bought it for the village for the summer, I don't know how it performs in the winter, but I highly recommend it for the summer 1000%!
I have installed it in a country house, in the spot where there was a connection for a water heater, and it has been working perfectly for 3 years now. It only takes 10 seconds for the hot water to start running, and what's impressive is that if I open the kitchen faucet on the lower floor, the hot water comes normally. The electricity bill has never been inflated! I am thinking of installing the same one in my permanent residence.
It has been installed in a kitchen for three years. Its performance, which is easily adjustable, is very satisfactory in both winter and summer! I cannot express an opinion on its performance for showering or bathing.
I have a pressure cooker that as soon as it starts working, it drops the water temperature by 8 degrees, resulting in cold water coming over you.
Even if it passes through a minimal amount of water and if you put it at maximum, the water only goes up by +5 degrees and in no case can you say that it has any effect.... stay away, I tried 2 pieces and they had the same result
I waited to evaluate it during the winter. Yesterday it reached minus three and part of the water pipe is external, while the rest is underground. The water temperature reached five degrees, but after some flow, it increased to twelve because the pipes are underground. Those that are above ground are at risk of freezing and breaking if the water does not flow a little. When I tried it, the setting was on inverter. It has four settings, and when you install it for the first time, the setting is on the lowest scale, which you need to change unless it is summer. This setting is around 2 kW and it is beneficial to have it during the summer so that you can simultaneously use other devices that consume a lot of electricity. During the winter, however, it requires 5.5 kilowatts and should be set to the third scale, inverter. At first, when the water was frozen, it took a while to raise the temperature. It stayed at 33 degrees out of the 39 I requested, but after a while, when the hot water from the ground arrived, it reached 39 degrees normally. The flow was satisfactory, and I have set it not to run too much to save water. Increasing the flow to full results in a temperature drop to 32 degrees, which is good for winter as I don't need that much water and 32 degrees does not freeze. So, if someone has a problem, they should check their installation because if the temperature is low, it will freeze and the pipe will break. The purchase of the machine cost 80 euros in total from China
During the winter, when the water gets colder, the flow needs to be reduced in order to have enough time to heat it up. Satisfactory machine.
Works perfectly during the summer.
Ideal for vacation homes
Stay away! I bought this for a studio apartment and it does nothing. I bought another brand for my house and I am satisfied. The label says it is made in China and it is not Greek. I wonder where users see its Greekness.
It performs in the winter with an input of 8 degrees Celsius and an output of 42, with a flow rate of 2 liters per minute. It cannot be disproven because I asked a mechanical engineer and he told me that it is logical for a 5.5 kilowatt to have this performance!
I measured it with a one-liter bottle. For those who try to take a shower with a flow rate of 2 liters per minute, they probably will never do it again.
I was swayed by a previous user's comment about high performance. It is not true. Pure disappointment.
Not 150€ or 120€ on sale, I wouldn't even give 50€ again.
I bought it 2 years ago and I am completely satisfied. Its installation is very easy and it is made of quality materials (at least the external plastics that are visible). It is user-friendly with its touch screen. I set the temperature once and I don't risk scalding or freezing with the water adjustments. Its own shower is necessary because it releases the little water it heats with pressure and it is sufficient. It works perfectly in single-phase because I choose the power that my electrical installation can provide at any time with the three available kW levels. I am waiting for it to go on sale again for €120 to install it in my country house. I highly recommend it.
Unfortunately, I fell for it thinking I was reading. It doesn't perform at all. Let's start with the fact that it is Chinese and not Greek. It says it on the label. Let's move on to the performance, which should run at about 2.5 liters per minute in the winter, and still it doesn't reach the temperature I want for a shower. This is not enough quantity. 5.5 Kw is too low for this job. I was thinking of connecting it to the solar panel, but it shouldn't take hot water because it damages it and it needs a thermostatic valve that costs around 90-100€. It's only good for handwashing. Nothing more. It's as Chinese as it gets. Not enough for two people, not even half. It's a waste of money.
It was purchased a year ago, 2 pieces on offer for 120 euros. Let's not forget that they are inverters, so both were installed in a series, one in the bathroom and one in the kitchen with hot water input from the existing solar water heater. I saw savings of 1200 kilowatt-hours in the quarterly bill of 3000. No problem with water pressure, valves have been installed and I have set the maximum flow rate and it works perfectly. Sturdy small construction, fully touch-sensitive and above all Greek. Congratulations to the manufacturers, I am very satisfied.
School editing 14/03/18 1) Many things depend on the water pressure it has. 2) Temperature does not require special valves, the ones that come with the packaging are enough. 3) It is called an inverter because it has temperature reading sensors both at the input and output, so if it drops below 23 degrees Celsius from the hot solar water, the inverter stops the machine and we use the water from the water heater. 4) Greek design and made in China, what can we do about it? Siemens and other companies are also made in China and they cost twice or three times as much and don't offer anything more, the only thing for sure is that whoever wants to buy Siemens or AEG from China will have the same thing with double or triple the money.
It is a product of high quality construction, unique I would say for this type of device. Fully electronic and compact, with its functions being performed by touch-sensitive buttons. It heats the water very quickly, although it does not have good water pressure. Also, in winter, the output temperature does not correspond to what it indicates due to the temperature difference of the incoming water compared to summer. I believe that for a product in this category, you should try it first in a store, evaluate many things such as water flow. Both this product and all others from different manufacturing companies need their own specific phone, which essentially allows a certain amount of water to pass through and increases the pressure that it has taken care of due to its function. So be careful in your choice. With the phone that one may have or a shower column, it does not work properly, although you can use one that has excessively small holes specifically for low water pressure and make adjustments, but it will give overheating messages. I believe that the water adjustment valve at the inlet has no value, so I removed it. Whether you have high water pressure or not, this reduces it to work satisfactorily.
Among the very positive aspects is the complete independence from the water heater for the bathroom, as it covers the whole family no matter how many members there are and at whatever times they want to take a shower. The freedom to choose to use the bathroom in winter or summer is something incredible. Additionally, there is electricity saving.
Edit: I am forced to give it two stars in its rating, but nevertheless, during the summer months, it remains our main device for heating water in the shower. I don't use it alone, but also three other people in their homes, whom I have to consider. Let's talk about the installation in my house, I changed the boiler and the plumber increased the water pressure. For a period during winter, I isolated it and only used the boiler, where the whole family realized the benefits of a boiler and the high water pressure that a conventional "water heater" has. When we closed the radiators and went back to using Solcore after two months (we used the electric resistance of the boiler in the meantime), there was great disappointment due to the obvious low water pressure. I had to find a way to not use its funny phone without knowing in the long run what cost it would have for the life of the device. Nevertheless, its use is positive and I am relatively satisfied. Just like you can get used to its phone, you just need to spend more time in the shower!
Winter or summer, hot water instantly and electronic temperature adjustment per degree Celsius. Despite its small size, it has no problem raising the water temperature to where you set it, even during heavy winter. Great electricity savings (over 70%) compared to electric water heaters.
Very good, it's worth it for the cost it has.
It is easy to install and heats comfortably with water input from 3 degrees to 55 degrees Celsius, which I tested during the winter.
It also has a lot of pressure without lowering the temperature, as happens with regular heaters with something similar that I had before I bought the Solcore F1, which is also smaller in size.
It was purchased about 5 months ago. It was installed in the kitchen, in line with the solar water heater, with a flow regulator and bypass (for the summer, when very hot water comes down from the solar heater), while it currently gets power from the dishwasher socket, so I don't use it at maximum power. It works perfectly, has very readable indicators, remembers the settings, and overall "you put it in, set it up, and relax". It has proven to be essential for everyday use at the sink, as you have hot water for rinsing and dishwashing in seconds. Of course, the flow of hot water is small, which I expect to improve significantly when I connect it to a higher power source. Nevertheless, we are very satisfied with the device and regret not buying it earlier. I note that for the bathroom, which unfortunately was far away from the kitchen, I bought the NK1 from the same company (see evaluation there).
Update Aug2018: We have been using it for about one and a half years, now connected to a strong power line (3x6mm2). My initial evaluation still stands, with the following additions: The water flow in winter should be low, even at maximum power, if you want to achieve a satisfactory temperature. For the kitchen and our preferences, this flow is absolutely sufficient, considering that you have hot water in a few seconds. However, I believe that it would not be sufficient for the bathroom under any circumstances.
Having now the experience of using the larger NK1 device in the bathroom, I would choose it for the kitchen as well, despite its higher price. Both the F1D and NK1 are worth their money and the additional expenses and effort for their installation.
It completely replaced the broken solar water heater! It was connected to the bathroom with a T, which provides hot water throughout the house while also having a "telephone" for a shower in the bathtub. In the shower, the water is heated instantly to a temperature of 45 degrees and maintains its temperature, while in the rest of the house's pipes, the water has a satisfactory temperature (around 30-35 degrees) for the other household tasks. Perfect...
It only worked for three days, then it started malfunctioning
Very good because it has temperature adjustment and you know how much water output it has.
