Above is a picture of my insulated pex coming up thru the floor. Also my taco 010 pump and my bypass for the danfoss valve.
Here is a better picture of the danfoss bypass in case I have to leave town and flow water thru the whole system to prevent freezing.
Here is a picture of my boiler supply all inch and a half black pipe. I have a temp/pressure gauge to pressure relief valve to a Vortec air separator with a expansion tank below. The down pipe you see is my boiler protection return to a 140 deg Danfoss valve.
