The EcoStream is a recent innovation from Ontop. This ingenious development
combines a chimney fan / draft improver with a soot separator and offers
numerous advantages to users of wood stoves and their immediate surroundings,
thus responding to the current discussion about the nuisance of wood stoves.
The start-up phase together with the replenishment moment and the decay phase of
the fire are the moments when most pollution and smoke development takes place.
In the optimal burning phase, between these three phases, a modern wood stove
burns with hardly measurable emissions. The fan of the EcoStream immediately
provides negative pressure in the chimney, which ensures that the stove reaches
its optimum operating temperature very quickly. In addition, the fan ensures
that the refill phase, in which the cold fuel smothers the optimum operating
temperature, only takes a short time. The soot separator simultaneously ensures
that soot particles are trapped * and do not descend into the immediate
vicinity. With this, the EcoStream actively contributes to reduced emissions.
By adding ballast air from outside the home (+/- a factor of 10), the EcoStream
gives a clearly perceptible dilution of the flue gases. This results in a
lighter colour of the flue gases. The odour perception is also favourably
influenced by the dilution that occurs. Smell and colour perception decrease and
with that the nuisance for the environment!
* tested with particles with a size of 625
µm to 125 µm, an improvement of 2 classes on the Bacherach scale was observed in
all combustion phases.
The stream of air inside of the EcoStream is being transformed into a cyclone.
By the resulting centrifugal force solid soot particles are being pressed
against the wall and then into a buffer. In this buffer, the solid soot
particles are collected, together with the rain water that the EcoStream
collects by means of an internal collection system. As soon as there is
sufficient water in the buffer, the buffer clean itself by means of a drain.

The Ecostream comes standard with four adjustable
legs which have a range from ø 130 to 200 mm, an electrical kit
including wiring diagrams and textile tape that silences the sound of
possible vibrations. The Ecostream weighs only 10 kg and can therefore
easily be placed on top of a chimney. Moreover, the Ecostream is easy
to inspect and clean due to the hinged fixation.

The EcoStream must electrically be installed by a
local certified electrician according to local obligations (local
rules). Ideally one uses a plug and a switch (it can be obligatory
to install a certified maintenance switch).
