     Small but full of energy, FH trench heaters with fans will fill your room with pleasant warmth even in the coldest winters.

  • Quiet and extremely economical EC fans increase the convection efficiency more than 4 times, almost without any sound.
  • Due to extremely low inertia, can quickly increase and precisely maintain the set room temperature, providing the room with exactly as much heat as you require just when it is required.
  • Create an effective warm air curtain for large windows, without allowing cold to penetrate the premises. The heat is perfectly distributed throughout the room.
  • Operates very well with low-temperature heat sources, such as heat pumps or condensing boilers.
  • Fully floor-mounted, and therefore do not impede free passage.
  • Perfect for any interior, as the only visible element is the grill, the material and colour of which can match the floor covering.
  • May be walked on and can easily withstand the weight of a number of adults.
  • Supplied with a stainless steel casings and copper-aluminium heat exchangers, to ensure they remain extremely reliable over the long-term.
