Very good! Purchased for a 25 sq.m. open studio with good window insulation and a terrace above. It turns the room into an oven on the 2nd setting after half an hour and on the 3rd setting in 20 minutes. Sturdy construction, strong stable wheels, sufficient cable length, bulky. After about half an hour, the thermostat starts operating, while the unit continues to emit heat even after it has turned off. Reasonable increase in electricity consumption depending on use. Plus, the 5-year warranty from the store. Absolutely safe for sleeping, silent, no smell. It competes worthily with our old radiator, which we had bought for 100+. I think it's the best purchase I've made from Skroutz this year.

This radiator is useless. I will try to explain briefly why.

First of all, we bought it for 80 euros, supposedly on Black Friday, as a quick solution for a small office, thinking that 2.5 KW is more than enough for a room of about 15 sq.m. The problem is that it doesn't heat it up, even though it says it's for spaces of 30-something sq.m (I don't remember exactly).

To be specific, the room is carpeted, surrounded by bookshelves, so there are no free walls, only one opening, a balcony door but with double glazing, facing north but with thermal insulation, draft stoppers on the doors, and the fridge and computers always on. The usable floor area, where you can actually step, is about 7-8 sq.m. This room never gets above 17°C. I'm not even talking about the 1 and 1.5 KW settings, there it's like it's not working at all. I'm only referring to the 2.5 KW. After 3-4 hours it might take the edge off the cold a bit, you don't feel it so much in your extremities, but you definitely don't feel warm. If we open the door, that's it, it's like it doesn't exist. A 38 sq.m space, that is, two rooms with the door open, doesn't get warm even after 10 hours. Tested. 10 hours of continuous operation, that is, it consumed 25 KWh, just to barely see the thermometer at 17°C. Useless.

This is not normal. I happen to have a point of comparison, a DeLonghi around 110 euros, also 2.5KW and with good reviews here on Skroutz, which would heat a 16 sq.m room on the low setting and made a difference even in a living room of about 50 sq.m. I should have bought that one. Basically, because I remembered these features, I assumed—wrongly, as it turns out—that, okay, how bad could it be construction-wise, for a 20 euro difference, since they have the same power, and I chose this Primo because the other one wasn't available. Bad logic, right?

Technically, I don't understand why one radiator heats well while another with the same specs doesn't, so I won't take a position on that. I tried changing its position many times, hoping to find better airflow somewhere, I tried blowing air at it with a computer fan, with a fan heater (without the heating element on), and with a dehumidifier. Such hacks are not a serious solution. Its output, judging arbitrarily, seems to me to be around 1 KW, no matter where I turn the switch. I compare the heat it gives off with a fan heater and a convector heater we have. That's how it feels. The convector, for example, at 2 KW makes a much more noticeable difference. In half an hour the chill is gone, in an hour you feel comfortable, and in two hours you can sit in a t-shirt, so to speak. That's fine, but with the Primo, honestly, I don't get it, where do the 2500 W it draws from the wall go?

Its only use is if I put it under the desk, at my feet, to heat 2 sq.m, at least it can do that. As I see it, it will end up in the bathroom, also 2 sq.m, and I'll get a proper one for the room. It's just 80 euros wasted. Isn't that a shame?

So to close this—definitely brief—review, I suggest you stay away from this Primo. Not only should you not consider buying it, but even if someone gives it to you for free, better not plug it in.
