ThermoMaster Series

ThermoMaster Series Domestic Water Heaters

The ThermoMaster is RECO’s water heater with storage. It is a complete packaged unit that delivers up to 7.5 million BTU/HR as standard with storage capacity to help meet peak load demands with an uninterrupted supply of hot water.

The ThermoMaster provides high recovery rates, accurate temperature control, and dependability. They are designed for facilities with a central energy source. This energy source is typically piped directly to the unit in a mechanical room to provide hot water to a specific building or application. Units can also be piped in parallel to provide additional capacity or emergency back-up.

At the heart of the control system is the Control Master II® panel with a digital PAC controller. The Control Master II has an easy-to-navigate LCD panel for local monitoring and set point adjustment. It accepts remote set point changes and can re-transmit water temperature by analog signals or digital signals via standard Modbus® or BACnet® network communications protocols.
