Sorry dan, yesterday I poised a question , how to do a correct heat for hydronic heat ,as if I was a homeowner . The question was, the RIGHT way to do one . Either connected radiation or measure the house ,height of room ,windows and insulation.(This is for hot water not steam) I also check the input of the nozzle to see what is actually doing the job , And have found that the nozzle size is less then the load . My guess, is that the fudge factors are way more then needed. Any help guys.
