BAD EXAMPLES OF STOVES SETUPS
TRUE PUBLIC HEALTH HAZARDS
WHAT YOU SHOULD NOT DO
! |
|
PLEASE BE AWARE THAT POORLY EXECUTED SETUPS WHEREIN SHOWN, WERE
MAINLY INSTALLED BY COMPANIES WHICH WORK IN THIS AREA, AND WERE PERFORMED BY,
ALLEGEDLY, SPECIALIZED TECHNICIANS, OFTEN WORKING IN COLLUSION WITH CONSTRUCTION
COMPANIES.
WHEN THE GOAL IS “TO SAVE MONEY”, YOU GET WHAT YOU SEE BELOW.

BAD EXAMPLES ON HOW TO USE ROCK WOOL
IN MOST OF THESE SETUPS, AIR CONVECTION INSULATION WOULD BE IDEAL
|
|
THE RISK OF CARCINOGENIC DUST RELEASE IS WELL VISIBLE HERE, AS WOOL
PARTICLES ARE RELEASED THROUGH THE GRATES WITH THE HEATED AIR.
|
|
|
Poor sealing of the hotte using rock wool around the duct. Besides being
dangerous, it lets the heat escape.
|
|
Improper placement of the rock wool. The wool is not
fully covered with aluminum foil; furthermore, the
poor quality foil is detaching itself from the wool. |
|
|
|
 |
|
|
|
|
PICTURE TAKEN THROUGH THE FRONTAL GRATE
Rock wool placed on the upper slab of a hotte (fireplace hood) without
the required aluminum foil protection. |
|
Badly set rock wool on a regular stove without
housing (encasement). Some care was shown by the
covered couplings of rock wool on the back. However,
the frontal area hasn’t any aluminum foil covering
(see arrow in picture). |
|
These situations are particularly dangerous when the air is used for
heating children’s rooms, as the dust particles are inhaled by them,
causing the already known health problems. |
|
Dust is slowly released by the wool to the room
through the grate of the hotte (hood).
|
|
 |
|
 |
|
We can also see that the duct hasn’t any stainless
link, but only aluminum tape, which will eventually
melt. Odors are going to be released when the resin
starts to leak down the joint. |
|
We can see that inside the hotte, which is made of
pladur (plasterboard),
rock wool was applied; one of the areas even has 3
layers. As we can see, the technician didn’t want to
take the scraps with him, so he left them inside the
hotte. |
|
ROCK WOOL SLOPPILY APPLIED ON A
REGULAR STOVE WITHOUT HOUSING
The dust, released by the wool, will quickly spread
to the living room and bedroom through the grates
|
|
 |
|
 |
|
We also notice that a bit of everything (bricks, tiles, plaster, cement and
glue) was used to make the foundation of the stove, instead of using proper
materials. We also see trash and paper scraps at the bottom, which will
cause undesired odors. |
|
Rock wool, or a protection beam, should have been
applied on the displayed area (lintel). |
|
HARDLY
USED FIREPLACE ALREADY CRACKED, EVEN AFTER ROCK WOOL HAS BEEN APPLIED |
|
n this stove, no lower openings for air intake were
made, thus hindering the air convection. Only little
amounts of air exit through the grate. Besides all
the problems inherent to the poor setup, due to the
lack of a lower air intake, the stove efficiency is
very low. That’s one of the reasons for the stone to
have cracked, even using rock wool. |

RETIRANDO A GRELHA
PODEMOS VER LÃ DE ROCHA SOLTA DEVIDO À SUA MÁ APLICAÇÃO
|
|
It’s amazing how one can be so irresponsible while
setting up a stove.

more than 50 setups installed by the same unprofessional company. |

INSPECÇÃO E
ALTERAÇÃO DE UM RECUPERADOR (NORMAL) INSTALADO INCORRECTAMENTE |
|
Rock wool was inadequately applied, covering the
stove and hampering its efficiency, as well as
releasing its dust into the living room.

|
In the picture we can see that the
stove is completely covered in rock wool |
View of the stove after the rock wool was fully removed. As
we can see, its sides are also completely covered, preventing any heat
recovery at all. |

slab. |
|
SEVERAL
EXAMPLES ON HOW NOT TO DO IT |
|
THIS DUCT WAS LEFT AS SHOWN
A 180 mm stainless duct tucked into a 200 mm one. It
wasn’t used any kind of stainless link, only
aluminum tape which melts at 100º Celsius. No
sealing was applied, which will cause the heat to
leak upwards. The cardboard would release unpleasant
odors until it burned completely.
|
|
WITHOUT ANY DUCTING
The fumes go through this “maze” of bricks and beams |
|
|
|
|
|
REPAIR
AND MODIFICATION OF A POORLY INSTALLED STOVE |
|
A stainless duct connecting the stove was set, which
would let the fumes pass through its joints and leak
outside the fireplace hood (hotte), staining the
walls and ceiling and filling the house with smoke.
Despite being a good quality stove, its bad assembly
resulted in low heat efficiency. This stove had been
installed by a known company that works in this
business. Afterwards, we removed and modified it,
setting up a housing,
manufactured by us, and also rear ventilation. |

EXAMPLES WHERE NO FLUE PIPES WERE PLACED |
|
|
Picture of a hotte (hood) where flue pipes weren’t
set.
Besides this little “detail”, the fumes must go
through a beam and its iron girders to reach the
outer duct, which renders its cleaning impossible.
Demolition is needed to install a stove. |
|
|
|
|
|
|
Picture of a supposed flue pipe, where we can see
that the fumes pass directly through the brick frame
which leads to the chimney without any ducting,
which would allow the cleaning of the soot. There’s
a high risk of flue leakage through the brick
joints. |
|
|
POR INCRÍVEL QUE PAREÇA HÁ QUEM COLOQUE CARTÃO PARA
ISOLAR A ALVENARIA DE UMA HOTTE |
|
AMAZINGLY, THERE ARE PEOPLE WHO
USE CARDBOARD TO INSULATE THE MASONRY OF A HOTTE |
|
|
The piece cracked right in the middle |
|
As we can see, the piece melted in its center area,
due to heat exposure |

Sometimes, this is what you get when purchasing poor
quality stoves; to save some money, you may end up
with a whole lot of problems |
