ThermoMaster Indirect-fired Steam & Boiler Water Heaters provide high recovery, tight temperature control, and dependability. Forced circulation provides controlled, accurate hot water for high peak loads. By combining high recovery capacities with storage, the system makes effective use of the available energy source. They use steam, boiler water or HTHW as the heating medium.

Complete Packaged System provides multiple benefits

Components are engineered to specific application requirements. Water and utility connections can be hooked up in the field. Exact storage requirements for peak load demands are combined with a forced circulation recovery section. Spatial requirements are less than normally needed by conventional storage type heaters. Integral recirculation assures a full supply of hot water on demand. ThermoMaster is an excellent choice for commercial, industrial and institutional applications.
