25mm Thermopex 55′ Roll

55′ roll of 25 mm Thermopex. Heat loss less than 1/2°F on 100-ft length. 3/4″ ID, 25mm OD of Pex. 3″ OD shell. 55 Ft roll weights 42 lbs. 75 feet of the 25mm Thermopex will have about the same flow restriction as 100 feet of the 1″ Thermopex. With 60 or 100 feet of the 25mm Thermpopex the flow rates will be adequate for most applications when a single water-to-air exchanger and side arm exchanger is used in the system. 1″ Thermopex has a higher insulation value that results in lower heat loss and would be recommended on longer runs. It is recommended continuing to use the same 1″ Central Pex for inside the building where insulated Pex is not needed. ThermoPEX with 25mm PEX waterproof oxygen barrier PEX-A lines (supply and return) is more flexible and easier to haul and ship. It’s ideal for shorter runs and for the do-it-yourselfers. UPS shippable. Dimensions of the 55′ roll are 40″ x 40″ x 20″. Note that oversize fees may apply for UPS shipments.
