Patent ID: 8727607

Claim:
A system for calibrating a heater system for heating a surface of a structure, the system comprising: the structure; the heater system, including: a heater element; a temperature sensor proximate the heater element for outputting a signal indicative of the temperature of the heater element; and a controller for controlling the supply of power to the heater element in dependence on the signal to maintain the temperature of the heater element at a first substantially constant temperature; a reservoir for immersing the structure in a fluid for maintaining the surface of the structure at a second substantially constant temperature; a power supply for supplying an amount of power to the heater element; and a sensor for receiving the signal from the temperature sensor and determining a temperature at the temperature sensor, wherein the system is configured to calibrate the heater system by determining a setpoint temperature for controlling the heater element in dependence on the signal and the second substantially constant temperature.
