Placed in a 30 sqm bedroom
Serio 20
We sleep with this as the only source of heating
South Athens.
Completely silent.
Set at 25 degrees.
Amazing.
With the wheels you can easily move it wherever you want

The design is very beautiful.

I got it for the bedroom, it does its job just fine, it's silent, it heats up the room quickly and finally it has a weekly program which is very convenient for me (you set it once and forget it, just like a radiator)

I have had the 2000w Sirio heater for two years now. While it heats up, it makes so much noise that it is impossible to sleep at night!

I am coming back with a new review because the representative zesta.gr replaced it with a brand new identical heater at no cost to me!
The problem was factory-related and rare, as they told me. In fact, they will send it to Italy, its country of origin, to identify the problem so that there won't be another failure for someone else.
Kudos to you for respecting the customer and doing everything in your power to keep them satisfied!
Thank you very much.

Very good if you turn it on normally, it heats whatever you want, it just consumes power if you don't have it on eco. I think about it, I had it open for 2 months day and night for the babies, non-stop, and it cost me 300 euros, meaning 150 euros a month, it consumed non-stop, but I also used the eco function, which works fine. It's a good quartz heater, I used it and it consumed $100 a month, it's perfectly fine, despite what others say, it's perfectly fine, it's the best choice

Very good product and very good service from the service. We had a small issue and they helped us immediately.

The heater is perfect, I have placed it in my child's room and it works completely silently. It also has a safety feature where if you put something on top of it or your hand, it shuts off!

Excellent build quality. Heats up very quickly and the warmth is very pleasant. It has many functions on the controller. Highly recommended.

Although it heats well, the switch broke and stopped working. I had it for 1.5 years. I have yet to see how much it will cost to replace the switch.

It was my first experience with space heaters. I expected maybe more. Specifically, I bought the Sirio 10 model because I believed it would adequately cover a 12 sqm room with good insulation. It does the job, meaning it breaks the cold, but you can't say you'll walk around in just a t-shirt. Relatively difficult menu to use, with the disadvantage that once you turn off the on/off switch, you lose the date/time, etc. In this specific category for heating a 12 sqm room, I believe it would be better to go for the immediately larger model. The build quality is very good.

Good evening, I bought the radialight product. Guys, the radiator is excellent! Perfect atmosphere and heating in a 12 sqm bedroom. I highly recommend it! Merry Christmas

Quite satisfied. I have placed it on the wall of my bedroom. In very cold weather, I turn it on every afternoon at 5 o'clock (at 21 degrees) and at 11 o'clock when I went to sleep, I found the room quite warm. At that time, the thermometer in my room showed 16 degrees. I would lower it to 19 degrees and go to sleep. But there was a nice warmth in the room. In the morning when I woke up to change, the atmosphere and temperature were very pleasant. It saved me as I don't have heating in the bedroom. These days, I set it to 19 degrees (the other thermometer shows 15) and at night for sleep, I set it to 18 degrees. I still don't know about the electricity bill. But I truly believe that for a small room like mine (9 square meters), it is perfect.

Having experience with other brands of heaters, I purchased a Radialight Sirio 20 and a Radialight Sirio 15. The performance is absolutely satisfactory, with very good heating quality and many programming functions. It heats up very quickly and has a great design as well as a convenient way of transportation, as I have also purchased the stands for moving it from one room to another. I highly recommend it.

Amazing product, it really worth it!!!!

Excellent product. I am very satisfied with the purchase. I put it in the children's room, it heats up very quickly and then reduces the intensity and maintains the temperature. It has a digital temperature meter with accuracy up to half a degree. It creates a sweet warmth without drying the atmosphere and is silent. I did not see a significant difference in the electricity bill, more or less the same. Very high-quality product for its price.

I bought it and put it in my elderly mother's room who has a respiratory problem and a tracheotomy, and she is very satisfied with the atmosphere, the speed, and the performance. Also, it does not consume electricity for its performance. I highly recommend it

Very high-quality construction compared to other brands I have used in the past, much more sturdy and better use of the controller. I would definitely buy it again

Amazing heater that was recommended to me.
Despite my initial reservation, now only the heater works in the room, I deactivated the radiator.

For years, I have been using space heaters (2 other well-known brands) for heating in my house. This year, I also bought 2 Radialight Sirio heaters and I am really satisfied. The heating quality is very good, with excellent stability in performance, which is obviously due to the great functioning of the digital thermostat (it doesn't have the issue I had with other heaters that would freeze and then suddenly turn on at full power and become excessively hot). Additionally, they make no noise from expansions and contractions, unlike the old ones. But the most important thing is that I feel like I have full control over my heating, as I can accurately adjust the temperature I want in the room. I highly recommend the Sirio heaters without hesitation.

The machine is excellent. It heats up the room I use it in, about 30 sqm, very quickly. It has excellent construction and is completely silent. Its operation is very easy and it has excellent functions and programs. A very good choice and worth every penny and more.

Very sturdy and elegant body with easy handling. I chose it because of the European safety specifications IP it has, but it also turned out to be functionally flawless.

Beautiful heater that quickly and quietly warms our room. We have programmed it to automatically turn on and off at the times that serve us. In terms of construction, it is much superior to another well-known brand that we have. In the autumn, we will purchase another one.

Excellent product with very good build quality. It heats up the room very quickly and is completely silent. As for functions/programs, it does everything it promises and its operation is very easy. It's worth its money.

We bought this heater for a space of about 17 square meters, which it adequately covers. It arrived in sturdy packaging, its construction quality is excellent, and we really like its design (although this criterion is subjective). The heating it provides in the room is immediate and "pleasant" (it does not dry out the atmosphere) and its operation is completely silent. It has a digital thermostat with sensitivity that I think will significantly reduce consumption. Its handling is very easy and the manual in Greek is very informative. It has five operating programs, an open window sensor, and the ability to program it on a weekly basis. A very good choice!
