AERCO International offers an advanced Water Heater Management System for its Innovation line of high-performance tankless water heaters. Standard on AERCO’s C-More unit controllers, the new WHM optimizes operating efficiencies, eliminates standby losses, increases system reliability through reduced cycling and tracks daily domestic hot water demands.
Designed to sequence up to eight water heaters on the same system, the WHM ensures that all water heaters in the system are operating at maximum efficiency. It monitors firing rate, and opens or closes one motorized valve per unit, as required to meet hot water demand. The system incorporates a unique master/slave backup feature that provides automatic transfer of master functions to the next unit on the chain, in case of designated master unit shutdown. The master water heater determines the unit to enable or disable based on run hours, which helps balance unit run hours, reducing service and maintenance costs.
