No Chimney Required

December 10th, 2009

One of the growing trends in home decor is the  gas fire, which can come with or without a flue.  In general terms, a fire that comes with a flue needs a chimney for the venting of any dangerous gases that build up during combustion. Ashlea lights Marble Fireplaces

Conventional gas fires are open-fronted fireplace and inset into a standard sized chimney. The fire draws air from inside your living room to create the flames and the by-product gases escape up the chimney.  Of course, these fires look good but they’re not very good for the air quality in your home because the fire is constantly ’stealing’ air to keep on burning.

Flueless gas fires, on the other hand, are, as the name sugggests, designed to work without any flue at all.  Generally they use catalytic converters to convert the noxious gases into harmless vapour, which is then allowed into the room.

Balanced flue gas fires use an system allows the products of burning to pass out through the wall directly behind the fire while at the same time drawing in the air needed for combustion via the same route.  This type of fire is usually glass fronted and the appliance is completely sealed off from the room.

Power flue gas fires transport combustion products to the outside of the house by means of a fan at the rear of the appliance.

If you want to buy a new fire but are unsure about what type of chimney you have (if any), the quick rule of thumb is that homes built before the late 1960’s tend to have what is  chimney_typesknown as a Class 1 chimney, which is the typical brick built chimney.  Homes built after that time could have a Class 2 flue or a Class 2 pre-cast flue. The pictures should help you decide exactly what chimney you have but it is vital that you are certain what type of chimney you have before choosing your gas fire.

Chimneys and Chimney Sweeps

October 30th, 2009

A whole article about chimneys?  Yes, why not, there’s a lot to talk about… and a lot to learn.  Did you know for instance that, in the UK, there is a National Association of Chimney Sweeps (NACS)?

chimneysweepIn its 27th year now, the NACS was set up to promote high standards for the sweeping, inspection and maintenance of chimneys and it is the UK national trade association for sweeps, representing over 250 of them. Forgot those images of  young sweeps, just small boys,  being sent scuttling up chimneys by the fire lit beneath them, today new members of the NACS undertake compulsory training and on-site assessment.

They are also checked, prior to enrolment, for public liability insurance and to ensure they have all the necessary tools and equipment to ensure the public is well protected by the services of a professional sweep.

Given that sweeping chimneys is such an ancient profession, you might be surprised by the modern equipment many sweeps carry, including smoke generator machines and CCTV cameras to help them assess chimneys and diagnose any faults.

If you have a solid fuel fire, the NACS recommend that you have your chimney swept at least once a year; this, they say, is because all appliances, whatever fuel they burn, be that coal, wood, oil or gas, need to be able to ‘breathe’ in and out. It is for this reason that current Building Regulations, Document J, stipulates that suitable access is provided for the cleaning and inspection of flues – so you must ensure that soot doors and cleaning plates on flue pipes are incorporated into any newbuild fireplace.

As much as a chimney sweep does for the care and maintenance of your fireplace chimney, he also does far more.

Chimney sweeps double as in-home fire prevention specialists. While they are busy scrubbing away at the crud in your chimney, they are feverishly searching for any unsafe condition that can lead to a chimney fire, or unhealthy or fatal air quality. In truth, chimney sweeps don’ t just clean your chimney; they can also save your life.

With this in mind, you could do a lot worse than select your sweep from the register of the NACS and, to help you do so, they provide a useful county list of registered chimney sweeps.

Fireplaces and Chimneys: A Brief History

October 1st, 2009

Recent research for a novel based in 17th century England highlighted just how much fireplaces and chimneys can tell us about how our ancestors lived. These architectural features were not simply essential tools for living, they were the very heart of the home. They tell us too about technological advances at the time of build, as well as changing styles of interior decor. Furniture may become sawdust and textiles may rot but hearths remain to tell their tale. crying by fire

The word hearth was originally used simply to describe the part of a room where the fire was made; initially constructed  simply by beating the earth to compress it. This fireplace came to be constructed from stone, brick and tiles, the earliest fires being retained in a simple shallow stone pit.

Similarly, chimney design went through a number of changes before they became something we would recognise today. The first chimneys were, in fact, simple holes in the roof that allowed the smoke to escape, thereby freeing householders from choking on it, and they tended to be confined to cooking areas and kitchens. As always, necessity was the mother of invention.

Governments and rulers have always understood that taxation on necessities is a good earner, and fire has always been a necessity, so it was that the Anglo-Saxons paid their smoke farthings to the king, unless they were deemed to be too poor to afford it. Then, in 1662, the English government levied a tax on all hearths, save those in the meanest cottages.  This 17th century tax was a profitable one and, at two shillings per hearth,  resulted in £170,000 a year flowing into the government’s coffers; it was also unpopular tax and was repealed in 1689.

From the 12th century onwards, chimneys survive in profusion, however they were so costly that only the rich could afford them, the rest of the population relied on timber smoke hoods were used to draw the smoke from the room. The wisdom of using timber to build a structure so close to an open fire is debateable. Up until this time, dwellings were simply one storey constructs; it wasn’t until masonry chimneys and fireplaces replaced the smoke hoods that ordinary houses could have more than one floor.

By the 17th century, however, chimneys had become so desirable an architectural feature that  houses were actually designed around them.  This is why, in some homes from that era, you will see that a stone chimney stack is the sole supporting structure for not just one house, but the one next door too.

It is, though, from the fire’s fittings and accoutrements that we can learn most about how life was lived.

History of the Chimney Sweep

September 25th, 2009

The history of the chimney sweep is a long and colourful one, and in fact it is one of the oldest occupations in the world – chimneys have been in existence for hundreds of years. However, the chimney sweep has only been recognised as a profession in the last 200 years, around the time of the industrial revolution, when chimneys became spacious enough for a man to fit in.

Paul Seignac: Child Chimney Sweep in Snow, 1876

In the 18th century, child chimney sweeps were a common sight. Such children were very small, usually boys between the ages of 4 and 7, and they were badly exploited by their employers. Employers of these young chimney sweeps liked to send children up the chimneys because they were small, yet the youngsters sometimes got stuck up the flues, which were often still hot, and many were killed in this way. In any event, all child chimney sweeps were covered in soot and suffered from the associated effects. They also endured painful sores and scratches on their skin from being confined in a small space.

Most children were employed until they became too big to enter the bottom of the chimney, and this was a godsend for these children. The tragedy is that the plight of the child chimney sweep was largely ignored in the 18th and 19th centuries and their misery continued for many years. William Blake graphically told of the plight of the child chimney sweep in his poem The Chimney Sweeper.

A bill was passed in Parliament in 1788, named ‘The Act for the Better Regulation of Chimney Sweepers and their Apprentices’. This ruled that chimney sweep apprentices must be 8 years or older, but this was never fully enforced, so child exploitation continued for many years after. Finally, in 1875, a law was passed that made it illegal for anyone under the age of 21 to work as a sweep – this saw the end of the child sweep, ending the miserable existence of thousands of such children.

The history of the chimney sweep continues today, with the business still thriving in the UK. However, the role of a chimney sweep has changed somewhat, in accordance with the passage of time. With the invention of central heating came a decline in the use of real fires and thus a decline in the need for chimneys – however, many homes today still have a solid fuel fire, and such chimneys need sweeping once or twice a year. Also, modern chimney sweeps will perform an inspection of a chimney before sweeping, to check for structural or safety problems – if there are any such problems, most chimney sweeps are able to put them right.
