Zerostart 3305004 Circulation Tank Heater 2250W 120V Engine Block Heater
This Zerostart 3305004 is a New Old Stock (NOS) Circulation Tank Heater, a heavy-duty 2250W 120V engine block heater designed for dependable cold-weather starting. This robust engine preheater requires a 20-amp service (NEMA 5-20 plug) for its 18.8 A operation, making it ideal for commercial truck, equipment, and industrial applications. It features a regulating thermostat that activates at 60°F (16°C) and turns off at 80°F (27°C), plus a secondary automatic-reset safety overheat thermostat, and fits 3/4-inch (19 mm) coolant hoses. Built with one-piece die-cast aluminum construction, a water-resistant terminal cap, and a permanently connected power cord, this coolant heater uses thermosiphon circulation to naturally warm and circulate coolant through the engine block, reducing cold-start wear and tear.
