Radiant Heated Slab

I have a 28' x 40' garage with five 200' loops of  1/2"pex tubing in the slab. What is your recomendation for a wall mounted direct vent condensing propane boiler?  Thanks.

    without knowing more

    (like a proper heat loss calculation) I'd probably be looking at a Triangle Tube PTS60 or a Lochinvar WHN-055.

    the Triangle tube...

    unit is nice. Another option I would consider is the Bosch Greenstar 57.
