In-floor heat

Is awesome in a calving barn. Dropping a calf on 50 degree floor vs a cold one makes a huge difference.

How do you set that up? Ive never heard of that before.

My dad put this same thing in our shed before I was born but this is how it works. There is either 1 or 2 coiled pipes underneath concrete that are filled with something maybe water? (I cant remember what) that is heated and pushed underneath the floor that heats up the concrete and then the concrete heats up the air.

Lots of buildings in this country are heated with in floor heating. It is a great way to heat a building.Lots of car garages and machine shops are heated in this manner, and it works very well.  Hot water is pumped through the plactic pipe lines under the floor. Some people pump cold water through their lines in the summer to help cool down the building. A neighbor of mine has a wash rack and calving barn heated with this in- floor heating, and it is wonderful. If you wanted to, I'm sure you could walk around this building in your sock feet on a vert cold winter day and be very warm.

It is called radient heating.  Very common in the Southwest.  Coils with water are encased in a top layer of concrete before the flooring is installed.  Usually done with tile or stained concrete floors.  When I lived in Santa Fe, it was nice getting out of bed and stepping on to warm floor.  Not sure how warm, but if the room was 70 the floor hat to be 80...

Wouldn't build a shop or calving shed without it......  Very efficient, stable temp lots of positives,  Slightly higher cost initially
