A Draftbooster chimney fan is an electrical fan. It is installed on the chimney, ensuring that your wood-burning stove gets enough air to burn cleanly all day long with no problems. The Draftbooster chimney fan creates negative pressure in the chimney, eliminating the problems you may encounter when burning solid fuel.
A Draftbooster creates negative pressure in the chimney.
When you turn on your Draftbooster, a draught is created in the chimney, making the fire burn cleanly and smokelessly.
You can use a Draftbooster on any chimney with insufficient draught – both steel and brick chimneys with an inside diameter of maximum Ø220 mm.
The solution of a mechanical chimney fan is actually a 50-year-old invention – and today is already in place on quite a few chimneys around the world. However, the solution was not designed for visibility – but rather for efficiency. This is why most of the time you will not notice that a chimney has a chimney fan installed.
An analysis shows that 1 in 4 homes with a wood-burning stove has problems with lighting the fire or with smoke in the living room. Unfortunately, this is often something you live with – or completely give up on trying to solve. Now, with the Draftbooster, the solution is at your fingertips.
A Draftbooster chimney fan is located on top of the chimney and ensures proper draught for the wood-burning stove or the fireplace insert.
The Draftbooster chimney fan is electrical and is controlled from inside the house using the included ON/OFF remote control.
The wireless plug needs to be placed as close as possible to the ON/OFF switch in order to ensure a good connection.
Often, the natural draught in the chimney is insufficient – and the problem only gets worse, as we make our homes more airtight and energy efficient, installing air conditioning and powerful range hoods.
There is not enough air to go around in a draught-free house, and it is very common for the stove to have insufficient air – the result is difficulty lighting the fire and smoke in the living room.
In quite a few places, you can install a Draftbooster chimney fan instead of making your chimney longer.
The Draftbooster chimney fan sends the smoke up high in the air, ensuring that fumes and particles are kept away from the roof and your neighbour.
With a Draftbooster, you can avoid having a tall eyesore of a chimney.
No. Draftbooster provides a chimney draught that is equivalent to the draught in a properly working chimney.
A revolving chimney cowl can solve some of the problems, but only in windy conditions when the cowl is spinning – and problems usually occur in calm, windless weather.
The price difference between a quality cowl and a Draftbooster is typically around £150 so the question is whether or not you need something that works regardless of the weather.
You can easily install the Draftbooster yourself.
The Draftbooster comes with a detailed installation guide.
On any chimney with insufficient draught – both steel and brick chimneys.
Draftbooster can be installed for closed wood-burning stoves with a capacity of up to 8 kW.
There are mainly two options: The first is to lead the Draftbooster cord underneath the chimney flashing. Most chimneys have a metal flashing where the chimney base meets the roof (typically covered with a sealer compound) and the cord can be led into the house through here. A second solution is to lead the cord down along the roof slope, underneath the first row of roof tiles and into the attic/loft.
For aesthetic purposes, we recommend that you secure the cord to the chimney wall with some pipe brackets (and possibly a metal pipe) in order to make the cord less conspicuous from street level.
If your chimney opening is square or rectangular, you will need a steel flange like the one pictured below. These can be bought off-the-shelf or commissioned at your local smith.
Yes. Draftbooster can be used with both steel and brick chimneys. See our installation video on the ‘home’ page.
Yes. A Draftbooster either goes full speed or it is off. If the draught during use (in a thoroughly warm chimney) becomes too great, you can turn off your Draftbooster.
The Draftbooster is built to allow fumes to escape, even if it is turned off. Therefore, it doesn’t have the effect of a “plug”, but rather as an extension of the chimney.
Your Draftbooster should be inspected at least twice a year in connection with the chimney inspection. Soot and other deposits must be removed from the rotor blades and the bottom of the engine housing. In order to extend the life of the engine, the Draftbooster must be turned on regularly – even outside heating season. For more information, read the included user manual. Alternatively, you can access the online version of the manual here.
By law, you must get the chimney swept by a chimney sweep, but the chimney sweep is not legally obligated to clean the Draftbooster chimney fan.
Therefore, it is up to you to make sure the Draftbooster chimney fan is cleaned at least once a year, so you can keep the outlet of the chimney clear.
It is extremely important to keep the Draftbooster free of soot and deposits. Soot is the primary cause of chimney fires.
Frequency of cleaning depends on how often you use the stove and Draftbooster. More frequent use requires more frequent cleaning.
With regular use of the stove (2-3 times a week), frequent cleaning of the Draftbooster may be required (2-3 times a year or more).
If the stove is used every day, more frequent cleaning may be necessary.
Regardless of how often the stove is used, the Draftbooster needs to be cleaned and inspected at least once a year.
A Draftbooster keeps birds and dirt out of the chimney, so it will not be obstructed.
Yes. Draftbooster has a small button on the front near the lid, which makes it easy for the chimney sweep to open your Draftbooster chimney fan and gain access to the chimney flue. When the chimney sweep is done, he will simply close the lid on your Draftbooster, engaging the automatic lock. The absence of screws means that the chimney sweep can work faster and that you do not have to worry about replacing lost screws.
A properly installed Draftbooster cannot fall down, not even in stormy weather.
The sheer weight of the Draftbooster, a steel wire and an angle bracket or flange keep the Draftbooster chimney fan in place atop the chimney.
Remember always to install the safety wire. With correct installation, the Draftbooster cannot fall down, not even when opened for cleaning and maintenance.
Draftbooster is comprised mainly of stainless steel, making it highly resistant to high temperatures. It has gone through rigorous fire and soot testing and meets all the necessary requirements.
Smallest: ⌀266 mm x 230 mm tall (see data sheet for further information).
A Draftbooster chimney fan weighs approximately 7 lbs.
Approximately 36 watts at full load. You can turn off your Draftbooster at any point - even when a fire is established in your stove/fireplace.
All sheet parts are made from stainless steel EN1.4301/AISI314.
No. The construction of the fan is effectively balanced with high quality ball joints and a very low noise level.
You will only hear a slight whooshing sound due to air moving through the smoke channel.
