I have radiant heat in my basement floor. Heard somewere that the temp should be below 100*.Is that correct? And why.

I had my set up designed by a radiant group up in Gardiner ME. because I had no radiant heating experience and all my "stuff" was going into the slab and that's no so forgiving for later corrections, (I have seen a wide renge of suggestions for loop spacing and legnth/layout in my reading) but I think that they try to shoot for the lowest water temps. needed to get the job done for efficency purposes.

Lowest possible supply temperature to satisfy heat loss. A win, win combination.

It would seem that one can set the flow rate higher and use a low supply temp or a lower flow rate and higher supply temp. With storage, from what I read here it is better to use as low a supply temp as possible....With that in mind, What is the lowest delta T that is practical in a radiant slab?
