Trying to narrow down a possible baseboard heating leak before tearing up the floor
Looking for some opinions on a suspected hydronic baseboard leak under a slab.
I ran the system for a while and scanned the area with a tc005. Most of the suspected loop path looked fairly consistent, with surface temperatures around 79–82°F.
One section stood out at roughly 71–73°F and appeared noticeably cooler than the surrounding floor. The rest of the run tracked pretty cleanly on thermal.
I'm not saying thermal imaging is a silver bullet, but that cooler section definitely caught my attention.
At this point, the options seem to be:
\* Open the slab and replace the affected section
\* Abandon the run and reroute above grade
\* Isolate that zone and switch to mini-splits
\* Bring in a leak detection company before getting destructive
For those who have dealt with slab leaks on hydronic systems, would a cold section like this raise any red flags, or am I reading too much into the thermal image?
Would you trust the thermal scan enough to justify professional leak detection, or would you be looking for more evidence first? #home source
