Vent terminal apparatus and methods are provided for covering vent pipes in an HVAC system, e.g., air intake and combustion gas exhaust pipes of a furnace or boiler. The vent terminal includes a body defining a shielded air inlet configured to fluidly communicate with an air intake pipe, and an exhaust opening configured to fluidly communicate with an exhaust pipe. The vent terminal also includes a nozzle configured to couple with the body and defining a flowpath therethrough. When the exhaust opening of the body is in fluid communication with the exhaust pipe and the nozzle is coupled with the body, the flowpath is in fluid communication with the exhaust pipe via the exhaust opening and the flowpath is oriented at an acute angle relative to the exhaust pipe.

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.
