Choosing a Stove
Choosing a stove sounds so simple yet
can become an expensive mistake if you overlook some key questions.
At Clearview, our in-depth knowledge and love of stoves will make
choosing your stove an easy and enjoyable experience.
Together we will take you through:
- your exact heating requirements
- the type of fuel you wish to burn
- your space requirements and proportions
Whatever your requirements, there is a Clearview
stove that is the perfect solution - offering superior design and
fuel burning efficiency at exceptional value for money.
Vs Open Fires
A pound of fuel will produce at least
three times more heat when burned in a stove than when it is burned
on an open fire.
In addition to this, a stove requires
considerably less air in order to burn the fuel than does an open
fire and so cold draughts are usually eliminated when a stove is
fitted. An open fire will continue to suck warm air from the room
as long as the room is warmer than air outside, and so all the heat
produced by an evening fire is lost to the sky at night. Heat produced
by other sources such as a night storage heater or radiators is
also sucked up the chimney.
When these matters are taken into account,
perhaps we can expect something like eight times more heat from
a stove than an open fire. This means that not only can a stove
heat the very largest rooms, the heat can also be expected to rise
up stair wells and warm landings, travel through floors and take
the chill off bedrooms. This heat will be absorbed into the walls
which act as heat reservoirs.
In many cases a simple room-heating stove
can go a long way to heating a whole cottage, or take a load off
an existing central heating system in a sizeable house.
Heating with wood or solid fuel has few
limitations; the limitations are our independence and how much we
wish to reduce our reliance on the nuclear, oil and gas industries.
whether hard or soft, is an excellent fuel and
by far the cheapest commonly available. Ideally wood should be burned
with a moisture content below 20%. A small stove will burn 3 to
4 tons, larger stoves 5 to 6 tons and central heating boilers (50,000
to 75,000 BTU) can burn 10-15 tons per season in average use. Wood,
when burned in a modern stove, is clean, economical, good for the
garden (the ashes) and above all it is a renewable resource.
such as peat, or compressed paper, straw, or wood waste
can be burned in most wood-stoves. As they often have a very low
moisture content, they burn very hot. They can be mixed with logs,
but do not overfill the stove .
Coal or solid
fuel could be considered as convenience fuels, in that they
are compact and no storage is required. Though considerably more
expensive than wood, its high density means a small stove can be
operated on as little as a one cwt. bag full a week. This is far
cheaper than economy 7 or bottled gas and there are no transmission
losses, pipelines or nuclear waste.
Traditionally wood-stoves have been long
airtight boxes that burned wood on a bed of ash, using air from
above the fire. Coal stoves had tall, cylindrical fireboxes with
air travelling up through a grate and the fire. Two very different
The majority of stoves on the UK market
have started life as either a wood-stove, to which a grate has later
been added in order to call it a multi-fuel stove, or a coal stove
that is large enough to burn wood reasonably well. Very much a compromise,
especially when they may have not been particularly efficient originally.
The hotter wood or coal is burned, the
more complete the combustion. The particularly high combustion temperatures
reached in the Clearview firebox results in clean glass, cleaner
chimneys and high efficiency. Whenever possible a stove should be
allowed to heat an area by natural convection, or with the use of
ducting, or fans. In some cases hot water or central heating may
be an additional benefit. The unique modular construction of Clearview's
stoves allows various boilers to be fitted at any time. It is rare
to find stoves that have large boilers which can be fitted or replaced
in the future. Fitting a boiler in any stove will increase sooting
and tarring of the glass and a clear view of the glass may be impaired.
It is essential that a wood-stove is
airtight, so good sealing round all doors is necessary. Gaskets
or seals will compress after a short period of use. For most stoves
this means air leaks. The rapid hinge and catch adjustment on a
Clearview means air-tightness can be maintained. Clearview’s
door catch can be adjusted in about five seconds without tools.
Internal door catches, common on many stoves are prone to corrosion
These are some of the features which
we believe put Clearview in a class of its own.
and Flue Lining
A chimney is a passage from the place
of combustion to the outside world. Warm flue gases should rise
through this passage to the point of exit. For a chimney to operate
satisfactorily it should be smooth, warm and as straight as possible.
If a chimney is irregular and rough, or cold and damp, flue gases
will move slowly. Cooler gases will mean inadequate chimney suction
and poor flue gas speed.
We always advocate flue lining where
possible for the following reasons:
- A flue liner will substantially decrease your chimney
volume. Consequently, higher temperatures will be maintained and
flue gases will travel faster, generating a greater and more consistent
draft. When possible, flue liners should be insulated, increasing
flue temperature. A warm flue will collect less deposit, cleaning
will be much easier and condensation should not occur in the flue.
It is possible to clean a lined flue well, leaving the liner almost
as clean as new. It is rarely possible to remove all deposits
that accumulate in unlined flues as there are always holes and
corners a brush does not reach.
- The combination of a Clearview clean burning stove
and a warm flue liner should mean chimney fires are a thing of
the past. Chimney fires are a common and frightening occurrence
in an unlined chimney and may cause substantial damage.
- A well installed stove should emit no smoke or
fumes to the room. If a flue is damp and cold it will produce
a poor draft, this poor draft may reduce further during slow burn
periods as the flue cools. Chimneys are usually in much better
condition externally than internally. Many years of sulphur attack
may have eaten half way through brickwork and mortar. Internal
feathers dividing one flue from another may have perforated or
collapsed allowing flue gas to pass into redundant, uncleaned
Clearview Stoves produce little smoke;
some five times less than conventional stoves. They are tolerant
and less demanding than other stoves and will operate in most unlined
chimneys, however we advocate lining to avoid risks and long-term
problems. When using a stove to heat radiators we would advise a
well insulated flue liner is used without exception.
