How a Wood Burning Space Heater works


If you have an area to heat and are looking for a far cheaper solution to fossil fuels, then a Zero Ridge Fabbri Space Heater could be the right choice for you.

If you have access to  wood or clean waste wood then a space heater is without doubt a cost effective and efficient way of heating your premises.

You can install and run these units almost anywhere. They are designed to heat large areas by funneling clean hot air directly into the surrounding area. Exhaust gasses need to be vented through the wall or roof to the outside.

  • The space heater can be sited in almost any dry location.
  • Any solid stable floor.
  • Chimney needs to exit the building and meet any local building regulations.
  • A designated safe zone around the space heater is advised.


Your space heater should be sited with the recommended minimum clearances. We recommend that your heater is installed centrally within the building. This removes the requirement for further ducting, which will allow to heat the largest of premises effortlessly and efficiently.

How it Works

Room air is drawn into the space heater from a lower panel and is circulated around the combustion chamber, where it is heated before being vented into the room via the ducts on the top.

The combustion gasses never mix with the clean heated air as the two chambers are completely separate.

Heating remote areas

Additional ventilation ducts can be added. However due to the large built in ventilation fan hot air will be circulated over very large areas.



Its very simple. Paper or cardboard with smaller kindling laid on the grate. Load with larger wood and in minutes heat already being produced.



Simple cleaning and maintenance. General maintenance is the removal of ash when required and once or twice a year a general clean and chimney sweep.
