Possible problems with wood burning stoves, their reasons and solutions


General recommendation

It is always recommendable to pre-heat the stovepipe before heating up the stove. This is done with a piece of newspaper within the stove near the outlet. This causes the pipe to warm up very quickly and will improve the draft. Following a list-up of possible problems, their reasons and solutions.

Unsatisfying heat

 

Cause: Too much heat lost by the thouse.

Minimal solution: Seal up doors and windows.
Optimal would be the installation of double pane windows and a good insulation of the house.


Cause: Bad combustion caused by unsufficient draft.

Solution: Improve the working range of your chimney.


Cause: Lecks in the outlet

Solution: Change your outlet system


Possible cause: External part of the outlet is cold.

Solución: Insulate the outlet.


Possible cause: Outlet connections seeping.

Solution: Check the installation.

Uncontrolled combustion

 

Cause: Outlet too long

Solution: Put in an isolation flap or shorten the outlet

Cause: Outlet overdimensioned

Solution: Put in a pipe with appropriate diameter inside the chimney or reinstall the outlet with appropriate diameter.

back

 

Unsufficient combustion

 

Cause: Outlet overdimensioned.

Solution: Reinstall the outlet with appropriate diameter


Cause: Strong winds

Solution: Install a wind protection

Smoke coming out the stove

 

Cause: Cold outlet

Solution: It is always recommendable to pre-heat the stovepipe before heating up the stove. This is done with a piece of newspaper within the stove near the outlet. This causes the pipe to warm up very quickly and will improve the draft


Cause: Outlet blocked

Solution: Clean the entire outlet. Generally it gets blocked by excess of soot


Cause: Outlet overdimensioned, too narrow or too short

Solution: Always install the outlet with appropriate diameter and with a length of at least 4 meters


Cause: More than one device connected to the outlet

Solution: Keep closed all connected devices

back

 

Varnish of the pipe damaged

 

Cause: Excessive draft

Solution: Check the draft. Might be it needs an isolation flap

back

 

Rebound of air

 

Cause: Combustion range extremely low.

Solution: Run your stove within appropriate combustion range


Cause: Cold outlet

Solution: Preheat the outlet before putting on fire the cold stove

Cause: Outlet blocked

Solution: Check the outlet and the connections, because if blocked there can be an excessive accumulation of tar

Cause: Outlet with in appropriate dimensions

Solution: Reinstall the outlet with appropriate dimensions


Cause: Outlet too short

Solution: Increase the length of the outlet.


Cause: Outlet with infiltrations

Solution: Seal the connections between the pipe segments

Is it posible to heat the whole house with a wood burning stove?

Yes. This can be realizec by installing a central heating system. With a common stove usually this is not possible

back

 

What is Soapstone?

Soapstone is a volcanic stone of grey color. It has vast termic energy enabling it to store an impressive amount of heat.

Some of the WAMSLER stoves have an external finishing with this material. Together with the double combustion system this provides a considerable improvement of efficiency

back


What fuel can be used with WAMSLER stoves?


Most of the stoves are designed to burn wood, although in many of the models also cole can be used. Other sort of fuels, like plastic or organic waste, cannot be recommended because they cause a lot of residues and diminish the durability of the device

back

 

What are the advantages of a WAMSLER stove compared with an open chimney?

 

Open stoves belong among the most estimated equipment of a household, but the inconvenience of smoke, the low ratio of efficiency (aprox. 10%) and the risks of open fires are not very recommendable. A closed stove provides following advantages. Las estufas abiertas son uno de los equipamientos del hogar más valorados, pero por la incomodidad del humo, la escasa aportación térmica (un 10% aprox.) y el riesgo del fuego abierto no tan recomendados. Una estufa cerrada aporta estas siguientes ventajas:

1.)Enormous increase of efficiency (up to around 80%), because the heat does not escaped unused through the chimney. The heat is distributed by air convection and not only by radiation like with an open chimney.

2.)Control of combustion. An open stove or chimney not only does not transmit much energy to the room, it also does not allow a controlled combustion. Therefore it always at maximal range and the load of wood does not last very long. A closed stove alows to regulate the speed of combustion and so increase the durability of the load.

3.)Increase of safety. For many users this is the most valued issue, because they can leave the house or sleep calmly while the stove is still in function.

4.)Convenience and neatness. The smoke of the combustion does not penetrate the room where the stove is. This avoids bad odor (although the flavour of the wood keeps persisting) and dangerous increase of toxic gases. All stoves dispose of an ashtray, which simplyfies cleaning.

Who can do the installation of a stove or chimney?

The installation is very simple. Talk to a reliable mason

back

 

Is it recommendable to conect a flue pipe if the stove is inserted into an open chimney?

Yes, at least parcial. Not putting any pipe could cause problems because with the mix of cold room air and the combustion smoke within the funnel. Although the assembly of the tubes could require to break down the chimney this is a recommendable step

back

 

Is it more complicated to install a closed wood burning stove or an open chimney?

As a general rule the installation of a closed stove is easier (and cheaper) as the construction of an open chimney, because the draft can be obtained by pre-fabricated pipes of iron or steel without extensive works of masonry.

Is there any protection for the furniture necessary against the heat of the WAMSLER stove?

WAMSLER stoves are built with double steel panels. Those double panels diminish the safety distances to inflamable furnishings to 20-30 cm

back

 

What is the key factor in the installation of a stove or a chimney?

The key factor is the correct construction of the flue outlet. Without adequate draft the advantages of a stove cannot be enjoyed. Some of the basic rules are written down in this document. For further information please download the installation manual of WAMSLER. The three basic rules are having an outlet with enough height (4-5 meters), installing the outlet flue as direct as possible and install the outlet with the appropriate diameter

How works doble combustion?

First the primary air mainly burns the fuel on the grate. Then the secondary air supplied some centimetres above the fire box floor allows complete combustion of unburned particles in the flames. To obtain a second combustion the stove has to be constructed with a special design, because this process requires a particular combination of heat in the firebox, height, temperature and quantity of injected fresh air.
The stream of secondary air burns the residues of the first combustion and then passes the window like a curtain so that also the mayor part of residues on the window are burned, keeping it extensively clean. Watch out for vendors who sell stoves with the seal of double combustion, although they only have some simple openings in the upper part of the stove. It is not that simple.

Which sort of wood has good efficiency ratio?

Wood is an excellent fuel with huge termic capacity. To be really efficient it should be dry y of good quality like Eucalyptus (for closed stoves preferrable the red or coloured Eucalyptus).

back

 

What maintenance requires a stove or a chimney?

Apart from the regular removal of the ash it is highly recommendable to check and clean the whole flue outlet on a regular basis.
