My run is 220' from the house, from inside, goes to hot water heater then furnace coil and back to boiler. I have the CB 1" thermopex. I have a 5 ton blower in my house and a buddy sized my coil by blower capacity. I have my boiler set at 185-195 and usually average 185 to 190 coming into house. I lose 50deg over the coil. I have a 014 Taco pump and was wondering if I up-sized my pump to the next series and increased the flow, it should lower my heat loss correct? I want to add 400sqft of floor heat and am concerned about my loop not keeping up. Anyone have any suggestions? I don't want to spend another $2500 for another pex run, I know I should have used 1 1/4" pex but we all know about hind site! I lose about 2-3deg between house and boiler.
