SIMUHYDRO TM   is a hot water boiler simulator and troubleshooting training system, designed for students and HVAC service technicians. The simulator is an invaluable tool for teaching students the basics of hydronics/hot water boiler operation and troubleshooting, as well as improving the service skills of experienced technicians.

SIMUHYDRO simulates a generic gas-fired hot water boiler that a service technician would commonly encounter in the field. Indoor and outdoor temperatures, room thermostat, burner air-shutter, cold water and manifold pressure, and controls are all adjustable. Up to 30 different mechanical and electrical faults may be inserted into the simulator, as shown in the Fault Lists below.
