The insulating properties of many modern houses are extremely high and
Inner skin of plasterboard
many external walls are now constructed with an inner skin of
plasterboard, supported on a wooden frame which is thermally insulated
from the outer skin of brick. Having such a low thermal conductivity makes
it impossible to use the outer wall as the back of the stove's housing unless
a means of ensuring that non of the heat from the stove is transferred to
the house wall. Whilst this may sound daunting the reward will be a vast
increase in heating efficiency.
One solution to the problem is to leave a space between
the stove's housing back and the wall and provide ventilation to give an
air flow between the two. The housing should be constructed with
insulating blocks and faced with brick or an insulating board and for extra
protection the housing can be lined with rockwool but these should be
supported so as not to touch the stove body.
The provision of insulation and air flow will also apply to the heat reaching
the ceiling of the room and this will need extra care if the chimney is to
be routed internally through the property.
