Fabbri F240

Our commercial range of hot air heaters fired by wood. Designed for the larger building with multiple air changes and or large volumes.

The F240 model comes with a chimney flue fan. This fan activates from the controller and produces a negative pressure within the flue. A chimney system is still required to expel the products of combustion.

Wood fuel

Wood comes in many forms, when burning the most important is that it is dry. Small kindling will be needed to light the heater then large wood sections for continuous operation.

The F240, due to its large fuelling chamber, which is 740mm wide and 1040mm high can use larger wood sections and be loaded with more fuel each time it is loaded.

How to light your Fabbri space heater

It’s a very simple and very quick operation. Lay smaller kindling sized wood along with crumpled paper towards the front of the fuelling chamber. Open the air flap, light the paper and off you go.

The Fabbri has two front doors, the lower for gaining access for removing ash while the upper door allows access for fuelling the wood.

Automatic activation

The Fabbri includes a simple and easy to use control activation system. When the onboard temperature sensor detects heat in its upper chamber it automatically starts the air distribution fans which push cold air from the bottom of the wood air heater, up through the body and out of the distribution tubes at the top.

Directional air ducts

The F240 comes with 3 air ducts, giving a greater air flow and distribution

The directional exit air tubes allow the user to move the fast-flowing heated air to where its most needed by means of a simple rotation.

Air volume

The onboard fan will move around 17,800 m3/hr of air.  

Heat output control

The Fabbri is fitted with two air control flaps, an upper flap (secondary air) and a lower flap (primary air). The primary which is simple adjusted by turning a knob to increase or decrease the burning speed. While the upper secondary air control mixes air with the burning gasses to improve the burning efficiency.

Cleaning and maintenance

How often you will need to give the hot air heater a clean depends on the fuel used and quantity burnt. However, the system is designed to run for long periods between larger cleans smaller de-ashing can be as little as once per week.

Summer operation

As a very useful extra, the onboard fans can be activated in warm conditions to push cooling are around your workshop or factory.


Installation is very straight forward. Choose an allocated location for the wood space heater. If using the provided chimney installation kit, connect the flue together until it reaches the roof area. Mark and cut a suitable hole, continue the flue until it achieves the correct height. Fit a chimney roof support and flashing around the chimney and a chimney cowl if supplied. We would recommend an experienced installer to assist with the installation. Connect the electrical supply (details of power requirement are in the technical details).

Running costs

The on-board air circulation fan requires a small amount of electricity, (see technical table for details). No regular spare parts are expected if the boiler is maintained. Eventually you may require a grate or other part, but this should be a long way in the future.

Fabbri space heaters the low cost solution for heating industrial units, workshops or factories with wood heating.
