compliments of a past post by Harold Hydronicsnetwork.net:
If you want a complete heating system, use a complete system designed by a radiant heating manufacturer. Weil McLain and other manufacturers will provide an entire factory-warranteed package installed by a qualified representative.
Also a good site to get a feel for infloor radiant and its advantages: Wirsbo.com
I personally like looking at a roaring fire in the fireplace having grown up in timber country and that's what we had, but will be going with radiant in my next home. Luck, Kizmet
