Poor products !!! To avoid !!! Defect of paint peeling off radiators !!!
I purchased radiators in steel plate produced by Irsap SpA: bad products !!! In fact, after a little over two years from the installation, I noticed, with amazement and disappointment, that all the radiators in question presented an initial process (which then, over time, proved to be slow but inexorable) of paint peeling: this process it was such that the varnish had formed crusts that broke off sharply and easily, from the elements of the radiators, scraping and scraping with the nails of the fingers of one hand. Given the situation, I immediately deduced that the surface of the radiators had not been previously treated, during production, before painting, with a primer or a gripper: this is palmar evidence !!!, otherwise it would not explain why the paint comes off, as already mentioned, scratching and scraping with the nails of the fingers of one hand. Therefore it is clear and irrefutable that a basic paint protection has not been applied to the surface of the radiators. This thesis was then confirmed to me by several plumbers of my knowledge: in fact, these plumbers confirmed to me that the radiators produced by Irsap SpA tend to have this flaw in paint peeling, also telling me that some models even pierce !!! This is an unacceptable defect because the Irsap SpA radiators have characteristics that make them unsuitable for use. Final judgment: only 1 star (too bad that this field must be evaluated, otherwise I would have included as a final judgment "zero stars" !!!).
