The new PVI 1600 MBH Centurion compact, direct-fired domestic water heaters can underpin ESG initiatives. Centurion water heaters deliver up to 99% thermal efficiency and offer O2 Trim, which allows the unit to self-adjust and maintain optimal air/fuel rations for peak efficiency, as well as low emissions and maximum uptime reliability, the company says. Energy efficiency is further achieved via a dedicated hot water re-circulation connection and the advanced Edge Controller. Precise temperature control of ±4° F is achieved through dynamic feed-forward sensing. The compact Centurion occupies up to 65% less footprint than competing models, the company says.
