A heater system for heating a piece of equipment. The heater system includes a reversing valve, a refrigerant compressor fluidly coupled to the reversing valve, an evaporator fluidly coupled to the condenser and the reversing valve, a condenser fluidly coupled to the reversing valve, the evaporator, and the piece of equipment, and a controller. The controller is configured to cause the reversing valve to operate between a first mode and a second mode. In the first mode, the piece of equipment utilizes a refrigerant, circulating in a first direction and heated via the evaporator, to keep the piece of equipment within a desired temperature range, and in the second mode, the evaporator utilizes the refrigerant, circulating in a second direction opposite the first direction and heated via the piece of equipment, to defrost the evaporator.
