Hello Everyone.
As an engineering student, I've been reviewing this forum many years. This is my first question.
My team and I are designing a radiant floor heating system using pex tubing.
The inlet water to pex tubing is 180 F, we assume that the outlet temperature will have a delta T loss of 20 F. This return temperature will be mixed with a mixing valve and sent back to the floor at a temperature between 160-170 F. The second loop will again have a 20 F loss and again this returning water will be mixed giving a temperature of 150-160 and thus the eventually the temperature in the tubes will be lowered down to 120-130 F and maintained there until the house zone temperature is reached.
My Question is:
Will it be viable to install insulation on top of pex tubing to protect the cork floor since the inlet water is at such a high temperature. The manufacture recommends that the cork floor be subjected to 120-130 F temperatures. Since the system uses a mixing valve we can lower the temperature down to this point, but there will be a delay(not sure exactly how long).
So, is it viable to use insulation to protect the floor. Since this seems rudimentary that we are insulating against something that we are trying to heat, I'm really not sure.
Thank You.
