General information about heat
accumulating fireplaces
10
10
Heat accumulating fireplaces differ from other fireplaces
10
in that they are intended to provide a moderate heat
for prolonged periods with a limited time of burning.
10
Conventional fireplaces give off strong heat during the
11
burning period but with a very limited cool-down period.
11
11
The heat accumulating fireplaces from Nordpeis have
11
a long duct system where the heat developed in the
combustion chamber passes through the duct system
11
before it exits through the chimney. The heat from the
11
gases is absorbed by the material surrounding the
11
smoke ducts, and by the time the smoke exits through
11
the chimney, the temperature is reduced to little over
11
100 °C (212 ºF). The efficiency of a well-constructed
heat accumulating fireplace is thus far better than the
11
efficiency of a conventional fireplace.
12
12
A heat accumulating fireplace can keep an even
12
temperature throughout the day with only one heating
12
cycle.
12
Bypass Damper
12
When the bypass damper is open the smoke gasses
12
exit directly through the chimney without first travelling
12
through the duct system. This gives far better draught
13 which can be beneficial for lighting a fire when the
fireplace and/or the chimney are cold. The bypass
13
damper should only be open during when necessary
13
for short periods (10-15 minutes) at the time a fire is
14
lit, and at new loads, in order to prevent smoke or ash
14
escaping into the room. Persistent combustion with
14
an open bypass damper can result in exceeding the
maximum allowed chimney temperature.
14
14
Flue Damper
15
The flue damper seals off the fireplace from the
chimney. This is to ensure that as much as possible of
15
the stored heat in the fireplace is emitted to the room
15
and not out of the chimney after the last load in the
heating cycle. The damper has a small built-in opening,
16
so even when closed it protects against smoke being
produced and released. The flue damper must be open
during burning, but can be closed after the last load of
firewood has become ember.
Air Vent
When burning in a heat accumulating fireplaces the
air vent is traditionally kept open to a maximum. This
ensures optimal combustion and minimises carbon
deposits in the smoke duct system. In addition it makes
it easier to keep the glass clean during intensive
burning. However, should one wish for a longer burn
period and slower flames, the air vent is adjusted
and reduced. Salzburg is equipped with secondary
combustion technology, which can normally only
be found on modern fireplaces. This ensures clean
combustion and high efficiency, even at lower loads.
