Finnish innovation

Polar Heater Oy is a company specializing in wintertime and energy saving issues of cars and machinery. We operate as a retailer and wholesaler of Polar Heater products for large customers as well as other retailers. Polar Heater products have already been installed in tens of thousands of vehicles.

The mains-powered Polar Battery Heater is particularly helpful with start up issues during cold weather. A pre-heated battery charged four times better.
Polar Battery Heater is directly compatible with Defa and Calix systems. 
We also design and provide battery heaters for different electric vehicles.

Polar Energy Saver controls the engine heater and interior heaters, providing up to 70-100% in energy savings, depending on the outdoor temperature.

Polar Battery Heater and Polar Energy Saver are unique inventions that also comply with strict EU directives.
The products are also patent and design protected.

Our new product Defa-Calix adapter has become extremely popular as it makes both Defa and Calix systems compatible with one another.

The new innovation from CarDoc analyzes vehicle data collected from the car and detects hidden malfunctions. The service can also estimate whether the vehicle and its battery can handle upcoming cold starts. CarDoc knows when the battery needs to be changed and can inform you on the condition of the charger and the starter, fault codes and the location of the vehicle.

Finnish expertise at its best.
