Fabbri F28

The smallest in the range of space heaters. It is ideal for areas that require quick heating or constant all-day heating requirements.

The small footprint of the F28 means it will only take up minimal space yet produce large amounts of heat in a short time.

Wood fuel

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

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 flap, light the paper and off you go.

The Fabbri has two front doors, the lower 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.

The directional exit air tubes allow the user to move the directions fast flowing heat air to where its most needed by a simple rotation.

Air volume

The onboard fan will move around 2200 m3/hr of air.

As a guide, if the area to be heated is 15m x 15m and 2.3m high, the volume of air will pass through the Fabbri 4.25 times in 1 hour. So, the whole volume of that space will be reheated 4¼ times every hour. This is ideal in applications where external doors are open and closed on a regular basis.

Heat output control

The Fabbri is fitted with two air control flaps, an upper (secondary air) flap and lower (primary air) flap. The primary air flap is adjusted by turning a knob to increase or decrease the burning speed. The 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 install 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 chimney roof support and flashing around chimney and chimney cowl if supplied. We would recommend an experienced installer to asset 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.
