Excellent aluminum radiator 500/100 "NRZ". You can find a lot of reviews on various models of radiators on the Internet. But I will write my own, I hope it will be useful. The first thing I noticed it was made in Russia. Yes, the price is slightly higher than Chinese radiators, but the quality is also different! NRP radiators are made of high-quality aluminum alloy by the "pressure casting" method, have a sufficient number of side ribs, and the weight of one section is a bit more than a kilogram! The manufacturer provides guarantees for its products for 10 years, and 25 years of the service life, that all radiators are insured.
In our Rostov region, NRP radiators are sold in many stores, and consultants advised to purchase goods produced in Russia.
There were no problems during installation, all threaded connections were made qualitatively. So, we did not regret purchasing it!
