I wonder about those who comment negatively on this particular water heater. I have had it for 15 years, I have never maintained it, and if you go up to the roof it looks like new. As for the performance, it has not decreased at all and I am very satisfied.

STAY AWAY!!! Don't even think about it! The worst in quality and especially in customer service, they are never responsible for anything. I bought it 9 years ago, changed the collector 3 years ago because it broke?!?!? None of them could explain why and of course it was the "first time it ever happened" to them... 5 days ago the tank got a hole in it too. I called the company and they didn't even have a message at the call center saying they were closed for holidays, they expected you to figure it out on your own. STAY AWAY!!!

Very good solar with amazing performance replaced solar with lamps because it punctured the boiler very good or roof base sturdy and stable

The solar panel has been working perfectly since June 2008 until today, 13/5/2004, with a rating of 10 out of 10, receiving a 9. No problems at all these years. Lamia.

The company considers it logical and expected the 2.5+ hours required to heat up to 70+ degrees with electric power. I live in an urban center (Athens) on the 3rd floor. The previous solar water heater (30 years old) had hot water in 30 minutes. I have had this one for less than a month and it has been serviced 3 times under warranty (the first time the heating element was faulty and the next 2 times it simply doesn't heat adequately/fast enough). All electrical checks have been done, 16.5 Ah, and there is no leakage. Absolutely terrible - stay away

Two 160-liter glass solar water heaters were installed in different houses in 2007. Both boilers leaked this year, in 2023, with a difference of about 3 months. Throughout all these years, they worked perfectly without any maintenance, repairs, or cleaning, providing hot water even on winter days with sunlight, and we're talking about the Evros region. I was ready to only replace the boiler because the selective collectors and the base are as if I bought them yesterday. However, your comments about my boilers have raised doubts. Are they really that bad?

The solar water heater NOBEL is perfect, flawless performance! Flawless installation by the company AIRCON. Note that I am on the 2nd floor of a 5-story apartment building, so there are 4 floors above me! I have installed two panels and I have performance even in the winter!

The worst thing there is!! 6 years old and constantly having problems, the boiler is rotten and the water is running with rust, unacceptable for the amount of money I paid

160lt 2.6m triple. Very high quality and very efficient. With the first heat, definitely cover the collector. I have not connected it to electricity, only to the boiler. I cannot yet know about its durability (installation December 22), but I believe that with maintenance and proper installation, not just a pipe and a valve, etc., it will last for many years

I guys, I installed it and it lasted 6 years. It heats up very well, but because I researched it, Nobel has very strong mirrors and the toilet doesn't hold up. It has gone to Bulgaria and it's not like before (before, they lasted for years because the mirrors were not selective and far from double mirrors). Whatever you clean, make sure to look for stainless steel or copper ones

I have had it in my house for 12 years and its performance, even in difficult weather conditions, is extremely satisfactory. I maintain it regularly, approximately every 2 years, and my technician told me that it is in excellent condition internally.

Installation a week ago (20/6/2021). Everything is good so far, plenty of hot water. I have installed 4 square collectors, 1 square more than the normal, and that's why I have partially covered one collector for only 5 months per year. I will come back with a new evaluation.

4 showers and dishes, the water reaches 55 degrees at 11 pm!
1 8 2021
At three o'clock in the afternoon, the water temperature is 70.3 degrees Celsius

I put it on January 15th and I have had it for 2 months, I am very satisfied. We do 2 people bathroom and dishes at the same time, it raises the temperature very much but they told me that it needs a cover in the summer. Now it will show, but it is good

Quality solar water heater quite well-made, in the half year that I have it, I am very satisfied. Very important for it to perform correctly, there must be a proper installation

I have it for a year and a half. In my case, it turned out to be a fake. From spring until October, it has hot water. For the winter, it's terrible. Throughout the winter, I have to turn on the heating element because the water is only warm for one person. Of course, I will call the company that installed it in case there is a problem. I am on the 4th floor, far from the roof, but solar panels with 3 square meters provide hot water for all the lower floors of the apartment building. I will come back after the company's inspection, after disconnecting it electrically and reconnecting my old bathroom water heater because the Nobel one is faulty and poorly insulated.

The solar was installed on 12/27 in Athens. Despite the many clouds and cold of this winter, it performed excellently! Now regarding the quality, I am satisfied. You definitely don't expect it to last over 10 years, but that's pretty much the case for everyone in the market today. Update: today I discovered that in just under 6 years, the boiler has leaked

A good choice in this price range.
It won't let you down.
I've had it for 3 years now and it works perfectly fine (Athens, 3 floors, pipes up to the roof).
Replaced the terrible solar star and it saved me.

Update:
In its 5th year, it's still a worthy war dog

In design, construction, and overall detail (!!), this solar panel is top-notch. Although more expensive than some others, its quality justifies the price. The only issue I have had with the Nobel 2009 solar panel is that after about 8 years, the container developed a leak. The cause was a lack of maintenance, specifically salt buildup in the container. The only downside, as far as I know, is that it is now manufactured in Bulgaria.

Awesome solar panel, the patent for the roof base is original with the solar panel essentially supported by four large bolts, so you don't need to create a big "wound" on the roof. The base is easily assembled and the components fit perfectly without any issues. Bravo to Nobel for being a Greek company too!

I am extremely disappointed as I bought 2 water heaters. One never heated the water satisfactorily and despite bringing in 2 plumbers, I was never able to get it to work properly. The other one started leaking after 6 years, one year after the warranty expired.

Very good choice. I was torn between a more famous one and the Nobel.
In the end, it was a good choice, it heats up the water quickly but when it's cloudy, don't fool yourself that it will have hot water.
Also, when it's freezing outside, it doesn't keep the water warm until the afternoon, it cools down quickly, which I consider normal. After all, this will happen for very short periods of time throughout the year.
Satisfied with my choice

Very good choice and so far completely satisfied after about 5 years of use.
Heats up quickly due to its large collector surface, which is the most important thing for days with little sun.
That's why it's called "solar", because it heats up with sun and not with clouds, as many people think.
No solar heater heats water with clouds!
Also, a plus is that the water cools gradually and not abruptly, like with other water heaters.
After advice from a plumber (I don't know how true it is), "better a solar heater with a 2.6m collector than two smaller ones, because solar heaters with two collectors have losses at the points where the collectors are connected to each other."
