Case of the non heating steam system

In this case, the thermostat would shut off and the rest of the space would be several degrees cooler. The contractor changed the thermostat but the new one did the same. What caused the thermostat to reach the set point but the other rooms didn't?

Great detective work! Had a similar problem where I mounted the T'stat to a shallow Wiremold box with several knockouts removed. This put an air cushion behinde the stat and seemed to work great.

I love that idea Thanks for letting me know

Over the year's with limited wall space for thermostat placement, I've added short pieces of PVC piping as thermostat standoffs/spacers. A nice .5"/.75" airspace behind thermostat will usually allow enough standoff & gentle airflow to slide/glide behind Tstat so it senses actual room temperature. Obviously you'll have to utilize longer fasteners..it does work!

[@boilerroomdetective]

That’s a great idea Thanks

Smart detective work. Who would have thought. FLIR to the rescue. Isn't the obvious only so in retrospect?

[@boilerroomdetective]

Thanks I wonder if I would have found it as quickly without the FLIR Its paid for itself many times over
