Looking for advise on infloor heat setup 60x60

[mikewatson]

Looking to finally heat my building this winter , 60x60 2in foam under slab ,r13 walls14ft, r25 ceiling full height to peek , two zones both will be 50-60 degrees. Going to be propane fuel, was just looking on buying a pre setup panel system from menards and would like the 140btu comb boiler they have or the 199btu boil and then a water heater for hot water. Not sure what really to do . Anybody good with heating that can steam me the right direction or products ?

i'm learning also. look into open direct radiant system,,with a polaris heater,,no furnace needed,water heater gas fired does both water and radiant,radiantec.com i think...looks efficient and saves money with no furnace or chimney needed,,,heater needs 2"pvc exhaust vent

Pretty open ended questions. What specifically you need help on? determining pipe layout, spacing, manual-J heat load? Which plumbing layout to use? You may be in over your head. If your supply temp is targeted at that low of a temp, you'll need boiler return protection and you're out of the cheapy menards panel area in my opinion.

Floor tubing is already installed using loop cad I have two zones. One zone is for the office bathroom and paint booth area it is 15 x 60. Second Zone is main shop area . Looking for recommendations on a good boiler and panel set up that I can install myself. And yes I probably am over my head that's why I'm asking.

The hard work has been done. You have saved yourself plenty.

I would get a local real installer guy over there to evaluate just what kind of equipment you need based on the heat loss that is expected. Have him set all of that up and tell him that you can help if needed.

You really want these final steps to be done by a guy who knows what he is doing. It can make the whole system work at peak efficiency and completely safe.

I did mine just as you are doing. My guy built my "in and out manifolds" for cheap, wired everything up so that it works flawlessly. He was really good and performed a tidy installation (that is on his website still) and worked very reasonably. He also found me a great deal on a condensing boiler to boot. He worked on two weekends and told me just what parts he wanted me to do before he got there. 5 years later I am still very pleased. Cheap money well spent.
