I have warm tiles with no pattern in my kitchen. It started right in front of the refrigerator and has since moved to tiles in the middle of the kitchen. There is no pattern. Different tiles can be warm on different days. I haven't noticed an increase in my water bill but I'm confused to the cause. It started this past winter about six months ago. Could the issue be electrical if not plumbing? I also read that a broken water line underground could cause heat to be released through the cement. Recently the main water line was repaired by city workers. When I purchased the home 4 years ago the inspector stated that the wiring to the island, which runs under the refrigerator, wasn't ran properly through the cement, however, when I feel this wire running to the outlet (from within the cabinet) the temp of the wire is not warm. Unsure what could be causing the warm tiles!
Is your house on a slab or do you have a basement?
On a slab.
sorry i've been out of town. i had a plumber come by and sure enough it is hot water pipe leak. he suggested running a smaller pipe in the pipe tgat is leaking which would slightly decrease the water pressure. do you think i should consider this option or just reroute the pipe through the attic? thanks for your help.
