DEFA engine heatersThe best fit for every car
We're the world's leading manufacturer of engine heaters and provide customized solutions for each new model on the market.
What you get:
Reduced wear and fuel consumption
Each of our customized engine heater solutions provides efficient heating of your engine and motor oil. Warm oil has a lower viscosity and better lubricates the engine, while a preheated engine is supplied with less fuel and burns the fuel it gets more efficiently.
Part of a complete car care system
Installing a full WarmUp system enables you to take even better care of your car. A complete system also includes an interior heater, a battery charger, and automatic and manual app control. These components work together to protect your engine, battery, electronic systems, and more.
Simple and flexible installations
Our dedicated engineers select, customize and design specialized engine heater solutions for each new model on the market. Their goal is not only to achieve the best results, but also to make installing the solution as simple, fast and flexible as possible for the installer.
PTC heaters - flexible efficiency
NEW! PTC contact heater
Designed for WLTP compliance
Hose heaters may trigger coolant temperature sensors introduced as a result of the WLTP. Our new PTC contact heater eliminates this issue and is the best solution for many vehicles.
Ideal heat distribution and efficiency
Contact heaters warm the engine as efficiently as hose heaters, with an ideal distribution of heat. The self-regulating PTC element uses only the power required to heat the engine.
Rapid adaptation to new models
Combining a universal heating element with adaptor pieces designed for each car model enables us to have customized solutions ready in a very short time.
PTC hose heater
More flexible installations
The PTC hose heater is available in several dimensions and comes with hose connectors in several angles and dimensions, making it easy to install in most vehicles.
Reduced power consumption
The PTC element is self-regulating – meaning that the resistance increases in parallel with the temperature of the element. This ensures that no excess electricity is used.
Excellent security and durability
The self-regulating PTC element eliminates the risk of burn-off or damage to other components. The element design removes leaks into the heating element and of excess pressure.
The truth about contact heaters:
Some car owners mistakenly believe that contact heaters are less efficient than hose heaters. This misconception likely stems from the fact that the interior heating system in older vehicles got its heat from the engine coolant. For this reason, using a hose heater used to lead to warm air being blown into the interior of the car immediately after starting the engine. Compared to using a contact heater, this created the impression that the engine was heated faster or more efficiently. However, this is not correct. In fact, a contact heater warms up the engine just as efficiently as a hose heater, only by a different mechanism. The temperature of the air in the internal heating system is not a valid measure of how efficiently the engine is being heated.
In modern vehicles, valves have been installed to prevent heat from the coolant from being used to heat the interior of the car until the engine is sufficiently hot. The important thing is that the engine reaches its ideal working temperature as quickly as possible.
The best way to ensure a warm and comfortable interior is to install a Termini cabin heater or a full WarmUp system.
