Abstract
A heating mat for a condensate trap can include resistive traces which heat the mat. The mat can be adhered to the condensate trap, for example using pressure sensitive adhesive. A control thermostat monitors an ambient temperature and/or a temperature within the condensate trap. If a temperature is at or above a setpoint, the controller thermostat disables power to the resistive traces. If a temperature is below at or below a setpoint, the controller thermostat enables power to the resistive traces to heat the condensate trap and the condensate within the condensate trap. In an embodiment, the heating mat can operate at a voltage supplied by the furnace or from a power source external to the furnace.
