How a Stove works
How a Stovax stove works – and how to choose the right
stove for you
Today, stoves are available in many different
shapes, styles and sizes. The exact features for each Stovax
stove are given on individual product pages but, typically these
will incorporate an airwash system for the window; many have a
‘cleanburn system’ with secondary air; certain stoves also include
an ‘external air’ facility and yet others are fitted with integral
boilers to provide domestic hot water and run radiators.
Accordingly, below is an explanation of the
features you may wish to consider when choosing the right stove for
This is the air that is drawn into the stove,
typically at a low level to maintain the combustion of the solid
fuel being burnt. Usually, the primary air enters through a control
on the front of the stoves which can be adjusted to control the
amount of air entering the firebox and, thus, giving you the
opportunity to regulate the intensity of the fire. This, in turn,
will alter the heat output.
Primary air is the best way of controlling a
stove burning solid mineral fuels and may also be used to start a
wood fire however primary air is not normally used in a log fire
once the logs are burning well.
Stovax Airwash System
Airwash is a specific Stovax design feature
that uses a specially placed vent or vents to draw in cool air from
the room which is then heated and ducted to ‘wash’ over the inside
of the glass. This feature helps to keep
the glass cleaner for longer, allowing you to enjoy the glow and
flames to the full.
Airwash air is the
best way of controlling a stove burning wood and can be used
a small amount in a stove burning solid mineral fuels to keep the
Where Stovax stoves include a convection
system, cool air from within the room is drawn into the convection
chamber, the air is heated as it rises within the stove which then
flows out into the room. The hot air rising draws in more cool air
setting up a continuous flow maintaining added heating
Some Stovax models also have the option of an
electrically-operated fan to boost the convection process and
provide a quicker warm up time within your room.
Stovax Cleanburn System
Introducing pre-heated, secondary air into the
firebox at just the right point promotes efficient combustion of
any unburnt hydrocarbons which may be in the smoke. This
‘cleanburn’ process can greatly increase the combustion efficiency
of your stove and dramatically reduce the amount of unburnt
particles going up the chimney. This can reduce your servicing
costs and, save you money in fuel. It also gives you an improved
All wood and multi fuel stoves with a heat
output above 5kW will require the provision of additional air for
combustion into the room in which it is installed. An External Air
facility allows this air to come directly from outside your
building rather than through a vent into the room, thus eliminating
draughts and adding to the overall heating efficiency.
Stovax High output Boiler stove are
specifically designed to provide domestic hot water and/or run
radiators as part of a stand alone system. The number and size of
radiators you can operate will depend on the ‘heat output to water’
of the particular model.
Alternatively, you can ‘link up’ some boiler
stoves with your existing heating system. The ‘link up’ system can
connect with gas or oil sealed heating systems, combi’s, underfloor
heating, advanced electronic controls and solar panels, helping to
save money on fossil fuels and reducing your reliance on single

Smoke Control Areas
Most town and city homes are located in Smoke
Control Areas as designated by the Clean Air Act 1993. To burn logs
on a stove in these locations, the model installed must have been
granted exemption from the regulations by the government through
DEFRA. This exemption is given only to appliances which have been
independently tested to demonstrate particularly cleanburning
combustion. Otherwise, you may only burn smokeless fuels on a multi
fuel stove within a Smoke Control Area. Stovax have one of the most
comprehensive choices of stoves for use in Smoke Control Areas.
information on smoke control areas.
The difference between Wood burning only and Multi fuel
Wood burns best on a bed of ash with its
combustion air coming from above so wood burning only versions of
stoves have a flat fuel bed and no ashpan.
Multi fuel stoves usually have a riddling
grate for the effective combustion of solid mineral fuels but also
have airwash so that they can also effectively burn wood. The
riddling grate allows the ash and cinders from smokeless fuels,
anthracite or peat/turf briquettes to be riddled into an ashpan
below, maintaining the primary airflow through the fuel bed and,
hence, creating the optimum conditions for efficient combustion of
those particular fuels.
According to models, Stovax multi fuel stoves
may have either an internal or externally controlled system for
riddling the grate.

How to choose the right stove for you
We would always recommend taking
advice from your local Stovax retailer before
selecting your stove. However, the key factors to you
will need to take into consideration are:
- Style/ aesthetics you desire
- Heat output appropriate for the room/space you want to
- Fuel type – wood burning only or multi fuel
- Do you wish the stove to heat water as well as the room?
- Are cleanburn, airwash and efficiency important to you?
- Do you wish to burn wood on a Smoke Control Area?
The answers to these questions will narrow
down your selection and help guide you to the ideal stove for you.
