Brand new here...glad I found you all 
I have a system that has been up & running for 3 years. This winter it appears it is just not right house seems cooler than normal. Lots of questions but I'll take it a step at a time. I have a Boderus gas fired GB142-30 and it was just serviced. Onyx piping stapled to the bottom of the advantec sub-flooring- 200' loops if i remember right.
Pre -engineered wood flooring over the advantec. Two zones both 1st floor 1350 sq ft & 1000 sq ft. In addition the Boderus serves a hydro air unit . The hydro air is really a early spring ...take the chill off feature. I put the unit in for Central AC and just added a heat coil. We are located in New Hampshire so it gets pretty cold in the winter. We also use a Jotul wood burner that will heat the house alone by itself and the House faces south. Now that I have given you some back ground info my first question is I have a temp gauge at the watts manifold as well at each circulation pump. I see about a 8 degree difference between the two which I understand. the question is what temp should I be running at the supply side of the manifold. Right now I'm running around 106 at the pump and 98 at the manifold supply too cold? I was always worried about the pre-engineered wood floor but have never had a problem.
