Features to know about

Starts Smooth in Any Weather

On freezing mornings, a chilled engine can be stubborn. Thick oil, cold metal, and a straining starter all work against you. This circulating heater keeps coolant moving and warmed, so the engine turns over easier, runs smoother, and is ready to go when you need it. Instead of fighting with slow cranks, you can start the day knowing your equipment will fire right up.

Peace of Mind With Built-In Safety

You can plug it in with confidence. A built-in thermostat automatically cycles heat between 80F and 100F, while a secondary safety thermostat with automatic reset adds another layer of protection. That means steady warmth without wasted energy or risk of overheating.

Tough Enough for Real-World Use

Farm lots, job sites, or long nights on standby, this heater is made for hard use. The one-piece die cast aluminum tank stands up to vibration and resists moisture, and the permanently attached cord makes setup simple. Certified by CSA and UL, it delivers season after season of reliable starts no matter how harsh the conditions get.
