Wanting to tie in a floor loop 200' in basement to current valveless manifold panel w/out circulator, myson radiator sys. at 140 operating temp.
Adding a Tico injection for a single in flor loop Close tees at primary loop, obviously gate valve on return.
First question, do I have an 18" drop in my supply lijne befor the Tico or after.
Second question if I heat the subfloor above at 1st floor bath(3/4" fur, 1" thick mortar bed, ceramic on top) and installAl transmission plates to the existing subfloor what temp. should I run the H2O at to penatrate the 3/4" fur subfloor and mazamise the radient effect thruoghout the mortar bed
