In my opinion, big garages are one of the best applications for radiant floor heating. Included in this category are fire stations, aircraft hangers, highway garages, bus garages or other large vehicle-service facilities.
These buildings usually have several large doors that open, sometimes quite frequently, during inclement weather.

That thermal mass instantly springs into action, temporarily releasing heat at several times its normal rate. This allows regular comfort to be restored almost immediately after those doors get closed.
Other benefits of floor heating in such facilities include:
