Infiniti K Series tankless water heater from Bradford White Water Heaters uses STEADISET Technology to keep water temperature consistent and virtually eliminate the “cold water sandwich” with no internal buffer tank. It offers venting lengths of 2- or 3-inch PVC or polypropylene up to a max length of 280 feet; Scale Reduction Technology, or SRT, that provides improved performance, longer life and lower maintenance costs versus conventional tankless; and modulation in a 22-1 turndown. It works efficiently even at low flow rates and activates at just 0.45 gpm. It is easy to install and includes convenient top connections and built-in flush ports, and it has 1/2-inch gas pipe capabilities up to 24 feet. No combustion analyzer is needed to install. The series delivers efficiency up to 0.96 UEF, which helps maximize the financial benefits of choosing tankless. 215-641-9400; www.bradfordwhite.com.
