Franke instant hot water dispensers are point-of-use which means that these faucets produce water on an as-needed basis at the faucet, as opposed to whole house units which connect directly to the water main and treat everything that flows in from that pipe. No more running the faucet waiting for water to heat up, since the water is always at temperature. Have instant hot water at your disposal for hot tea, cooking or defrosting.Stainless steel tank (1 2 gallon) 60-cup hr. recovery rate NSF61 and AB 1953 Compliant Swivel spout Silicone tubing Broad operating temperature from 100 degreeF to 350 degree Increased tensile strength of 1100psi BrassCraft Flexible supply line connectors Longer life under harshest conditions Polymer-coated fibers, tightly braided around a strong PVC inner hose Highly flexible Specially engineered to resist corrosion by chemicals found in household cleaners Required HT-200 heating tank included Standard 1-3 8 faucet hole opening 3 8 Standard U.S. faucet tailpipe IAPMO, NSF61 and CSA approved FDA ApprovedAB1953 S152 Compliant: Yes Base Width: 2-1 4 Faucet Height: 9 Faucet Reach: 5-3 8 Filter: No Finish: Chrome Handle Type: Lever Handles: Single Hot Water Dispenser: Yes Number of Holes: 1 Side Spray: No Style: Instant Hot
