In earlier times, homes were heated by varities of fuel and chimneys were constructed to propel emissions outside to prevent pollution inside the house. Fumes were drawn out of the house using tubes within walls. Now these have become decor aspects of homes. These are built of bricks with fireplaces on all floors and caps to prevent drafts and water coming in.
These days, an external chimney adjacent to the external wall is also constructed as a decorative feature.
The chimney includes the base as fireplace. This setup can also include an electric heater including a counter space.
Modern treatments also include polished marble, granite or glass when a contemporary idiom is required. The spaces defined by the fireplace are ideal for curios, pictures and books. Soft lighting can be used to highlight decor objects and also for ambience of spaces.
Rising from fireplace is a stack that is a channel to blow smoke out. Nowadays, this area above the base is projected out of the level wall surface to mimic the actual design. This is a good area to display paintings.
The most distinctive element of this component of architecture is the stack rising well above the building. The stick is often broader at the base to handle the load above and becomes narrow as it rises upwards, For modern interiors it can be made of reinforced concrete and treated with other materials for the facade.
The crowning feature of this structure is the cap designed to protect the internal pipes. Nowadays they can be used as a mock, yet defining feature of the chimney. The construction could also be of brick or other traditional materials so that the elevation evokes earlier eras.
These days, chimney stacks are best used for a manor, country style, or farm house concepts of a home. In the urban context, it may seem discordant and the extra space required for the design may not be available within the minimal size of plots. If the elevation is highly stylised, then the chimney may also be embellished to suit the theme. Carved brick types are ideal.
The chimney adds a virtue of virtual verticality to a structure. Thought this is not translated into useable space within the home, on the outside, the added height makes the building imposing. The effect achieved is one of grandeur, with a subtelty that comes with the delicate proportions of the stack.
SELECTING AND LOCATING A CHIMNEY
Whether utilitarian or not, the chimney certainly enhances the elevation. It is an expression of artistry from the past and looks best when set in green surroundings in large estate with sombre rustic of red.
A chimney is a long-term investment so it pays to get the right chimney installed properly. It is easy to make mistakes in selecting and locating a chimney, so here is some reliable advice that will help you avoid problems and get maximum performance from your chimney and wood burning appliance.
Match the chimney to your stove or fireplace
To work properly, your new wood burning appliance needs a chimney that suits its characteristics. There are two main factors to match:
The chimney flue (the hole that gases flow through) should match the size of the outlet on the stove. Bigger is definitely not better when it comes to chimneys. In special cases (like with a very tall chimney), a chimney flue can be smaller than the appliance outlet. Always get professional advice before selecting a chimney of a different size than the stove outlet.
High performance stoves and fireplaces need high performance chimneys. And high performance chimneys always have insulation. If you have selected a purely decorative fireplace without gasketed doors and air controls, then an uninsulated chimney like conventional masonry or air cooled metal might be satisfactory. But if you have an advanced stove or fireplace, you'll need a high performance chimney like a 650°C model, a specialized fireplace chimney or a lining system in a masonry chimney.
Put the chimney inside the house
By far the biggest mistake you can make in buying a new chimney is to have it installed up the outside of your house. Outside chimneys allow leakage of cold air and odors into the house when there is no fire burning in the stove, and can lead to smoking when a fire burns. Here is why.
Give the chimney some of the heat
You might think that any heat flowing into the chimney with the exhaust is waste, but it is not. The chimney needs heat to stay clean and free from corrosive moisture. Don't be afraid to burn the stove or fireplace hot, at least for a brief period, each time you start a fire. This practice heats up the appliance and chimney structure and 'primes' the chimney to make reliable draft for the rest of the heating cycle.
