New Alaskan Police Station Locks Up Heating Efficiency And Safety With PEX Hydronic Systems

The snow- and ice-melt system uses 12,000 feet of 5/8 inch diameter MrPEX tubing with eight 11/2 inch stainless steel manifolds to circulate a 50% propylene glycol solution through 51 circuits. Snow-melting manifolds are supplied with the heated water/glycol fluid through 2-inch diameter pre-insulated PEX pipes with urethane foam insulation and a high-density polyethylene (HDPE) outer casing, buried in trenches. By designing the system with the programs our engineers use for the PEX, we were able to print out design load calculations, flow rates, head loss and other data for the project."
