I would like opinions of below floor and plate radiant systems vs. extended surface suspended tube radiant. I like the latter because of the omission of mixing requirements ...but does it provide heat comparable to a below floor and plate system if installed properly? If not ... can someone tell me how much of a difference there is and if there is any info of how to determine the amount of heat an extended surface suspended system can produce when supplied with a certain temp of water and flow rate etc.. Thank you, RH
