How do Nordkapp and Hallava heaters differ from "Chinese" (Vevor, Hcalory, etc.) diesel heaters?


Although Hallava and "Chinese" diesel heaters may look similar externally, there are significant differences between them. The specialty lies in e.g. in the heater unit. Hallava Air heaters are designed to meet the tests that require type approval. They have been tested and received Type Approval (E24) in the European Union. Basic Chinese diesel heaters do not meet these standards, which is why there is no corresponding approval. 

Nordkapp heaters also have E24 type approval.

Nordkapp diesel heaters have GSM phone control, so you can control the heater from anywhere.


Hallava and Nordkapp offer a two-year warranty on their heaters, while Chinese heaters usually only offer a one-year warranty. Hallava and Nordkapp spare parts and maintenance services are located in Finland, so you can get help quickly and easily if you need it.


Hallava and Nordkapp use the best fuel hoses, specially designed with the requirements of each device in mind. The Chinese heater uses green fuel hoses that are too loose.


Hallava and Nordkapp heaters generally use higher quality parts, which makes them more durable and quieter. For example, the fuel pump is designed to work more quietly, which improves the user experience. In Nordkapp heaters, the fuel pump is even quieter than in Hallava.

Staff Recommendation:  Buy Nordkapp or Hallava and pay a little more.
