Radiant floor heat question

[Cougar]

Have an existing 30x50 shop, putting on a 24x42 addition.
The new slab will be pinned to the existing.
Was considering in floor heat for the addition.
My question is:
Will the 30x50 slab draw too much heat from the 24x42?

Thanks

You can pin it and still have a thermal break in the joint. Me I have a heated and unheated area in the shop with no thermal break. Yes it looses some heat but not that much. It depends on how much efficiency you think you need.

I have 1,700 sq. ft. of my 2,400 sq. ft. Building heated with hydronic. There is a dividing wall between the two spaces that is built like the exterior walls. (2X6, vapor barrier, bat insulation, drywall) Under the wall I installed a thermo break of 2" ridged foam standing vertically. This stops all transfer of heat to the cold slab and cold to the warm slab. I also installed insulation and a vapor barrier under the cold slab to stop any moisture problems.
I am very pleased with the results.

Make sure the pins are smooth and coated.

No, not much heat.
