Using an engine heater on agricultural machinery is essential to ensure reliable starts in cold temperatures, reduce engine wear, and lower fuel consumption. Preheating the engine improves combustion, resulting in lower emissions and a longer lifespan for the machine.

The main difference between Calix and Defa engine heaters lies in their connection types—Calix uses flat pins, while Defa uses round pins, making them incompatible with each other.

Calix primarily focuses on hose heaters, which heat the coolant.
Defa offers both block heaters and hose heaters.
It’s crucial to use the same brand throughout the system, as Calix and Defa components are not interchangeable due to their different connection systems.
The best choice depends on your vehicle's requirements and which heater type is most effective for your engine.

At Sagroparts, we define an engine heater as an electric heater that preheats the engine before startup. It is connected to 230V and heats the engine block, coolant, or oil depending on the type. When the engine is already warm, startup wear is reduced and the machine reaches operating temperature faster.

It depends on temperature and engine type, but in most cases 1–3 hours is sufficient. At Sagroparts, we often recommend engine heaters with timers so that heating occurs automatically and does not consume more electricity than necessary.

Yes, many of our customers install engine heaters themselves, especially hose heaters and oil heaters. Block heaters are often engine-specific and require the correct model for your particular engine. If you are unsure, we at Sagroparts are happy to help you choose the right engine heater and accessories before installation.

It depends on the engine design and installation possibilities. Block heaters provide very efficient heating but are engine-specific. Hose heaters are more flexible and fit many tractors. At Sagroparts, we help you choose the solution that works best for your machine.

Yes, engine heaters are primarily used for diesel engines in tractors and agricultural machinery. Diesel engines are especially sensitive to cold starts, which is why we see engine heaters as an important part of preventive maintenance – particularly during the winter season.
