This family includes space heaters that cannot be considered completely mobile and for emergency use because they all require minor installation work.

They are normally used for traditional heating (warehouses, industrial sheds, laboratories, factories, etc.) and, thanks to the low cost of the investment, they are an excellent alternative to conventional heating plants.

These heaters have a vertical structure and are all with indirect combustion, using a heat exchanger that expels fumes through a chimney connected to the outside.

Therefore, they can be operated in closed rooms. On the other hand, they have efficiency of about 90% due to the heat lost through the chimney.
