Checked the Pex at the boiler and where it enters the house. I had several digital temp meters using type E thermocouples they took to long to settle out at temp. What I found to work well was a Fluke IR gun with laser pointer. I checked the whole circumference of the Pex tubes and found that hitting the Pex straight on in the center (avoiding the boiler tank behind it which skews the readings) gave me the most consistent readings. What I found after taking several readings is that I have a 2 degree temp. drop from the boiler to the house, also it looks like I am gaining about 1.5 degrees of return reheating from the supply line running next to it. This took some time but was well worth the effort and I have a better understanding now of what the system is doing. I also found that the maverick 732 remote temp setup I installed at the entrance of the house is about 3 to 4 degrees low. Fun stuff.
