Does it matter what kind of wood to burn in my fireplace or stove?

Not exactly, it is much more important that the firewood is of the season and rightly dry. All kind of wood contains approximately the same calorific yield per kg. But the softwoods are less dense, so if you buy the wood per cubic meter, kg will get less and therefore less heat. Also, some types of wood such as pine, pepper and pop incandescent sparks - so be careful with your carpet when you use the stove with the door open. The cork does not burn.

Make sure that your supplier of firewood gives you a good amount of underbrush to firelighters and small logs to light the fire.

Whatever the type of firewood you will use, make sure that your stove is well heated. A stove cold or in slow burning will not provide you any comfort and will only produces deposits of creosote, the unpleasant sight and smell, and the glass chimney.

What are the advantages and disadvantages of iron and / or steel?
Which provides the best source of heating for my investment?

We could write a lot of pages on this subject. The advantages and disadvantages apply more on manufacturing than in use. For you as user, the main difference is on appearance of the device. Iron gives you a more rustic with intricate carvings, etc.. Steel gives you a trendy look. The heat generated daily and effectiveness is similar. Remember that, in general, the heavier the unit the greater the time required for heating, but will stay hot for longer and probably will be more robust size by size. The important thing is that the parts of the stove that are in direct contact with flame are made of materials resistant to heat, made from the best quality and preferably easily replaceable.

Finally, who sales your stove is often more important than buying the stove. Choose not only an excellent reputation but also a renowned retailer. And remember - a heat exchanger is only as good as the chimney where it is installed!

When I turn my stove on cold, smoking instead of going up the chimney comes into the room. What should I do?

It is a common problem. A chimney is a heavy cold air mass with low cold draft. In this case you should move up this cold air mass. Before starting your fire, burn a few sheets of newspaper in the fireplace. This will warm your chimney without producing smoke and creating the draft needed.

I acquired a stove from serious ecological - Model E700. I note, however, that after installation and while I´m satisfied with the performance of the stove every day it forms a great accumulation of tar on the glass doors, especially on the left. Because it becomes very difficult to remove the tar even using adequate clean glass, I required this information about the reason why does tar forms although the used wood is perfectly dry.

There are some reasons to get your stove dirt:

1) Use of wet or green wood.
2) It is necessary that the stove is hot enough before closing the combustion air´s control.
3) Let the flame die out - to keep the glass cleaner is necessary to leave a slow flame.
4) The chimney doesn´t have a good draft.

Just bought an apartment in Lisbon where they have installed a heat stove. When I light it (after heated the fireplace with the some sheets of newspaper´s flames) and after a few minutes of burning, the smoke comes out the door. This situation doesn´t verifies / is less verified if I open the room´s window. Other reason could be exhaust fans in kitchen and bathrooms of the apartment. The side wall of the kitchen has installed air intake. Is there any problem or am I not comply with any procedure?

Thank you for your e-mail received. The problem is lack of combustion air to the stove, a common problem in well insulated homes especially those that have forced ventilation in the kitchen and bathrooms. If your house is well insulated with double glazing and has no air leaks through windows or down the doors (or have a few), then you should let fresh air gets in the room where the stove is installed and also in the kitchen / or bathrooms that have forced ventilation. Clearly the vents are not in reference area sufficient for these magazines and the stove. So you have two options:

1. Increasing the area of air intakes existing and / or
2. Putting a vent in the outer wall, preferably as closer to the fireplace as possible.

Ensure the following:

• minimum clear area of the grid must be 100 cm2;
• Do not place the used area of the room (sofa) between the grid and the fireplace to prevent drafts.
