I didn’t think this was plumbing—but when I did a search, this was the first site that was listed. My nephew bought an 85 year old home with radiators for heat. As they are about to have a baby, I was concerned with safety. I remember my grandparents having covers built around their radiators with vents on the top. Are those still avaialable — and where would I find them. Are there some safety issues he should know if. Where can we read about it. Thank you very much for your help.
