I installed a 5 wrap 1" lines 100 feet from boiler to house with temp gauge on feed and return at boiler and also where it entered the building. My temp loss has been 1degree each way in the ground. pipes are down 14" to36" with sand 6"below 8" on each side and6"on top with top soil. Had a few inches of snow with below freezing temp then temp went above freezeing for a few days and the snow melted where the lines were first. So i dont think my lines are bad with a 1 degree loss each way. What i'am trying to say is to check your water temp at each end before replaceing you lines it would be a lot cheaper.

I have bypass valves on the hanging heater and when its bypassed i still get the same temp. drop across the main heater. So not understanding how a close tee with a pump will reduce any head at the hanging heater.would a close tee setup and pump that came on with blower move water faster across the main heater and reducing temp loss? It is one loop system side arm first,175 exchanger second,hanging heater last
