Hey! Don't rag on that boiler, it is the same as mine lol. That room looks very familiar as well..

Pre existing slab

Agreed... this type if application requires R10 separation between new radiant panel and slab in Wa State, if the existing slab is not insulated. I'd be using at least a 3/4" piece of ply as a thermal break before laying the QT panels, per Mfg. instructions.

No, its not my room. I just have a similar one. Insulated concrete slab with a step down from the main house. It was an addition. I was just joking about the boiler. Thats the noisiest godforsaken hunk of junk I have ever had the pleasure of owning. Im itching to get rid of mine however it is in much better shape. I spent 700.00 fixing it up before I knew it was complete junk.

Couldn’t or shouldn’t be done?

I don’t mean to be obtuse but were these ACP’s placed directly onto the slab?

In the attached photos it appears that you’ve used nothing in between the CPs’ and slab below. I don’t see any means being used to attach the panels in any way. Further, you’ve placed a low mass system in direct contact with an existing “insulated” high mass slab. Seeing how the aluminum heat transfer surfaces of the CPs’ are in direct contact with the concrete slab below, I can’t see how this could be considered an appropriate application for heat transfer to the space above. The thermal mass of the slab will have a huge effect on the ramp-up and cool off cycles of the space above. If you were a BTU, where would you go?

The conditioned space will be maintained how?

OH Gary boy.....................................................

You're picking a fight with the wrong man. Jimmy the Gent has it under control. Believe me, you don't want to square off with him...he is without a doubt one of the top all-around heating men in The TRi-state area. A damned good plumber too. Don't patronize him. Mad Dog
