Zerostart Vehicle Heaters - ZE63RR
- Circulating Heater
- External Tank
- 120 Volts
- 1000 Watts and Up
- Zerostart
Cold weather can make standby generators and work equipment harder to start. This 1,500-watt tank heater circulates warmed coolant through the engine, with a thermostat that cycles on at 80F and off at 100F to help make cold starts easier.
Highlights
- Prepare Work Engines for Cold Starts: Prewarms coolant in generators, compressors, and farm equipment.
- Circulate Coolant Without a Pump: Thermosiphon flow carries heat through the engine naturally.
- Cycle Heat Automatically: Thermostat switches on at 80°F and off at 100°F during preheating.
- Added Overheat Protection: Separate safety thermostat resets automatically if heater temperature rises.
- Connect 3/4" Coolant Hoses: Inlet and outlet barbs match the large tank's required connections.
- Plan for a 20-Amp Outlet: NEMA 5-20 grounded plug needs a compatible receptacle for 120V power.
Features to know about
Get Engines Warmer Before Work Begins
A standby generator may sit for days before it's needed, while compressors and agricultural machinery can spend winter nights in unheated buildings. This 1,500-watt tank heater warms coolant and carries that heat through the engine before startup, helping reduce cold-start difficulty. It's designed for gas and diesel engines in generators, compressors, and agricultural equipment.
Move Warm Coolant Without a Mechanical Pump
This tank heater uses thermosiphon circulation. Coolant enters through the lower connection, warms inside the tank, and rises toward the engine through the upper outlet hose. As warmed coolant moves up, cooler coolant takes its place. The tank needs to be mounted low, with its outlet pointing upward and at least 12" of rise to the higher engine connection. Correct hose routing is what keeps the coolant moving naturally.
Regulate Preheating Automatically
The regulating thermostat switches the heater on when the sensed temperature drops to 80°F (27°C) and off when it reaches 100°F (38°C). A separate, automatically resetting safety thermostat provides additional overheat protection. These are thermostat control points, not a promise that every part of the engine or cooling system will reach the same temperature.
Check the Larger Hose and Power Connections
This large-tank model has 3/4" inlet and outlet hose barbs. It also draws 12.5 amps at 120V and has a grounded NEMA 5-20 plug, so you'll need a compatible 20-amp receptacle rather than a standard 15-amp-only outlet. The permanently attached 5' cord should be routed away from heat, sharp edges, and moving parts.
Mount the Tank Where It Can Operate Properly
The mounting bracket allows top or bottom attachment, but the heater itself must remain upright with the outlet pointing up. Choose a mounting surface away from engine vibration and leave at least 3" between the heater and nearby engine components.
Built for Cold-Weather Equipment Applications
Zerostart is a Phillips & Temro brand, from a manufacturer that develops engine and equipment heaters. This model uses a one-piece, die-cast aluminum housing that resists corrosion and impact, along with a water-resistant terminal end cap and permanently attached 5' power cord. These details help make it suitable for installation in protected equipment compartments where winter conditions and regular equipment use are part of the job.
Important Notes:
1. Mount the Tank Low and Upright:Install the heater as low as practical, preferably below the lowest point of the engine cooling system. The outlet must point upward, following the arrow on the tank. Mount the unit to a suitable frame or other stable surface rather than directly to the engine, where vibration can shorten heater life. Maintain at least 3" of clearance from nearby engine components.
2. Route Hoses for Natural Circulation:
Use properly rated coolant hoses and fittings sized for the heater's 3/4" inlet and outlet barbs. Connect the lower inlet to a low point in the cooling system and the upper outlet to a suitable higher engine connection. Maintain at least 12" of upward rise in the outlet hose. Avoid sharp bends, loops, and routing that could trap air or restrict coolant flow.
3. Use the Correct Coolant Mixture:
Phillips & Temro/Zerostart recommends a 50/50 mixture of ethylene glycol antifreeze and water for proper heater performance. Do not use 100-percent antifreeze or a mixture containing more than 60-percent antifreeze. Do not use the heater with stop-leak additives in the cooling system, as these can shorten heater life.
4. Fill and Bleed the Cooling System:
Allow the engine to cool before installation. Follow the manufacturer's instructions for connecting the hoses, refilling the cooling system, and removing trapped air. Never plug in the heater unless its heating element is fully immersed in coolant. With the heater unplugged, run the engine as directed to check for leaks and trapped air before using the heater.
5. Use a Compatible 20-Amp Electrical Connection:
This 120V heater draws 12.5 amps and uses a grounded NEMA 5-20 plug. It requires a compatible 20-amp receptacle. Use a properly grounded, GFCI-protected power connection and a suitably rated outdoor extension cord when needed. Keep the connections dry and route the permanently attached power cord away from hot surfaces and moving parts.
6. Disconnect Power Before Starting the Engine:
Never start or run the engine while the heater is plugged in. Engine operation can introduce air into the heater and expose the heating element, causing damage. Disconnect the heater from power before starting, operating, or moving the equipment.

Video Transcript for Review of Zerostart Vehicle Heaters - Thermostatically Controlled Circulating Tank Heater - ZE63RR
Hi, everybody. Andy here with etrailer.com. Let's take a quick look at the Zerostart Thermostatically Controlled Circulating Tank Heater. And when the temperature drops and the air begins to bite, the last thing that you want is an engine that is going to struggle to turn over. This circulating heater is designed to make those cold starts effortless by keeping your coolant warm and moving. So when you're ready to work, your engine's going to be ready as well.
On those bitter mornings, thick oil and cold metal can make starting your engine a chore. With this heater, the coolant's going to stay warm and circulating, helping your engine fire up quickly and run smoothly. Whether it's for your generator, compressor, or farm equipment, you're going to be able to save your start of the strain and skip the slow cranking altogether. You're going to be able to plug this in and basically forget about it thanks to a built-in thermostat that's going to automatically cycle the heat between 80 and 100 degrees Fahrenheit. There is a secondary safety thermostat with an automatic reset that's going to add extra peace of mind, ensuring consistent warmth without overheating or wasting energy.
If you notice here, the plug type here is CNEMA 520. Now the heater isn't just tough. It is made for real world use. It's one piece die cast aluminum body. It's going to resist vibration, moisture.
It's going to be perfect for rugged job sites or long standby periods. And with CSA and UL certification, you're going to be able to count on reliable performance season after season. Installation should be pretty straightforward as well. You're going to mount it from the top or bottom. And as you can see here, you are going to get the hardware that you're going to need to get this installed into place, along with instructions to guide you through that installation process.
So this is going to give you up to 1500 watts of heating power. The cord length is about five feet long or so. Giving you some measurements here as best that I can. Let's call this the length. So it looks like we're sitting pretty close to seven and a half inches long. The overall width, pretty close to, see if I can get my finger there so I can see. About two and three quarters inches or so. The overall height just from bottom to top, I'd say pretty close to seven and three quarters inches. So hopefully those measurements were helpful for you. The inlet outlet size is three quarters of an inch. But if you happen to have any questions about this heater or anything else that we carry here at etrailer, don't hesitate to reach out to us. We do want to make sure that you're getting exactly what you want and need. Well, again, my name's Andy. Thank you for joining me.
