Apparatus and method for heating and preventing freeze-off of wellhead equipment utilize radiant heat from a flameless heater to heat fluid in a heat exchanger, such as a tank or finned radiator. A pump is used to circulate the heated fluid through a conduit loop deployed in thermal contact with the equipment to be heated, such that the heat from he fluid is transferred to the equipment, maintaining it at sufficient temperature to prevent freeze-off. The apparatus and method may also be used for other purposes, such as for circulating heated fluid through a liquid-cooled engine to facilitate cold weather starting.
