Radiant heat air exchange.

[Overhaulin63]

My existing garage has radiant heat, and I just built an addition attached to the outside of one of the structure's walls and wondered if I could simply exchange air (forced air) from the heated garage to the other? The boiler was over sized for the existing building and would easily be able to heat both if areas if it were an open structure.
Any thoughts or concerns?

Radiant floor heat? Or something else?

Is the addition a garage? Or living space?

Radiant floor heat for a garage addtion.

Add another zone to the system, either in floor or wall panels if the boiler can handle the btus needed for both.

What water temp are u running? Standard fintube or air handler really doesn't heat under 140. They do make low temp fin tube.

Just running 120 degrees.

Radiant heat works by warming the slab, which then warms the air and then everything else in the room. How big the is addition, and how open is it to the main space? It will likely heat just fine as long as it's not too big and wide open to the main area. Floor will be colder though.

I was thinking along the same line with regarding radiant heating the air, but I was curious if anyone else had done it and what they experienced. The main space is insulated around the block foundation, walls, and ceiling so it doesn't have to work that hard to heat. The main is 32x60 and the addition is 32x32 (insulated walls and ceiling). I am just looking to knock the cold off of it during the Winter months and was just curious if anyone else here had tried the same.
