Hello. We have a Kent Tile Fire from the 80's. It was in the house we bought 4 years ago. We actually didn't touch it until last winter (after we had chimney inspected of course) and used it a handful of times. My question is, can you put a kettle on top of it to warm up water? Is it possible the top gets hot enough to cook something? I didn't try or even think about it when we used it, and it's 92 degrees now so I am not about to do it today! Any thoughts? In an emergency can I heat food up on it??? Thanks!
