14. FREQUENTLY ASKED QUESTIONS
How often should I have my chimney swept?
At least once a year. If you use your fi re more than three times a week on
average, have your chimney swept more often. Have the chimney swept by a
recognised company. Your fi re insurance policy may make this a condition and
ask for proof.
Does a fi replace insert have better output than an open fi re?
Yes, a fi replace insert has between 7 and 8 times the effi ciency of an open fi re.
(See also sections 7.2 and 7.3)
What is the difference between net capacity, gross capacity and effi ciency?
Net capacity (= Nominal output) represents the net amount of heat that the
appliance generates.
The total heat content of the fuel is the so called gross capacity.
Effi ciency is the percentage of fuel converted into useful heat. It is the ratio of
net capacity and gross capacity.
How can I keep the glass clean?
By making a point of using dry, clean wood in the stove. Wood that is too damp
immediately gives off lots of ash.
Make sure the seals are in good working order. Any air seeping out around the
glass part of the door will cool the air, resulting in the fi re not burning cleanly.
How much wood will I use?
That depends entirely on how you heat your room, what sort of appliance you
have and the size of the room you are heating. As a general rule, a fi re used in
accordance with our guidelines (no air under the fuel, topped up once an hour)
each kg wood produces an output of about 3 kW.
In an averagely-insulated house, the general rule is that in a room of 80 m
3
, you
need a fi re with an output of around 7 kW. For each subsequent 10 m
3
, add on
0.6 kW.
In a relatively well-insulated house, the general rule is that in a room of 80 m
3
,
an appliance of 5.5 kW is adequate, and for each subsequent 10 m
3
, you need
to add a further 0.4 kW.
