Fireplace

December 2nd, 2009

A fireplace is an architectural structure to contain a fire for heating and, especially historically, for cooking. A fire is contained in a firebox or firepit; a chimney or other flue directs gas and particulate exhaust to escape. Fireplaces are a central household feature, as the flames and crackling sounds are comforting, even when not necessary for heat or cooking. Fireplace mantels are a focus for interior decoration.

Types of fireplace

Diagram of a fireplace.
A. Cool air enters.
B. The cool air is heated and is released.
C. Smoke is released.

A fireplace may have: a foundation, a hearth, a firebox, a fireplace mantel, an ashdump door, a chimney crane, a cleanout door, a grate, a lintel, a lintel bar, overmantel, a chimney breast, a damper, a smoke chamber, a throat, a flue, a chimney chase, a crown, a cap, a shroud, or a spark arrestor.

Fireplace types:

  • Masonry (brick or stone fireplaces and chimneys) with or without tile lined flue. Unreinforced masonry chimneys do not stand up to earthquakes well.
  • Reinforced concrete chimneys. Fundamental flaws (the difference in thermal expansion rates between steel rebar and concrete which caused the chimney flues to crack when heated) bankrupted the US manufacturers and obsoleted the technique.[citation needed] This type of chimney often shows vertical cracks on the exterior of the chimney which worsen as the internal rebar rusts.
  • Manufactured (“prefab”) fireplace with sheet metal fire box and double or triple walled metal pipe running up inside a new or existing wood framed or masonry chase with a chase cover, a cap, and spark arrestor at the top to keep small animals out and sparks from exiting the chimney cavity. This type of fireplace is very popular for new construction for ease of installation and is very cost effective. This type of fireplace is currently being made for wood, natural gas, biomass and lp/propane fuel sources.
  • Ventless Fireplace (duct free fireplace) that are fueled by either gel, LP/bottled gas or natural gas. Some states and local counties have laws and ordinances regarding these types of fireplaces. They require little installation and do not use the same BTUs as a traditional fireplace. The gas burning version of a vent free fireplace while using less BTU’s worth of fuel, burn that fuel at close to 100% efficiency, making them very powerful heaters. This being the case, before purchasing a gas burning vent free appliance make sure to size it according to the cubic feet of the area it is going to be installed in. Aside from the heat output there are also air quality control issues due to the amount of moisture they release into the room air.

History

An outdoor fireplace

Ancient fire pits were sometimes built in the ground in the center of a hut or dwelling. Smoke escaped through holes in the roof. Smoke would be blown outside or back into the room. Chimneys, invented much later, partially fixed this problem, venting smoke outside.

In 1678 Prince Rupert, nephew of Charles I, raised the grate of the fireplace, improving the airflow and venting system. The 1700s saw two important developments in the history of fireplaces. Ben Franklin developed a convection chamber for the fireplace that greatly improved the efficiency of fireplaces and wood stoves. He also improved the airflow by pulling air from a basement and venting out a longer area at the top. In the later 1700s, Count Rumford designed a fireplace with a tall, shallow firebox that was better at drawing the smoke up and out of the building. The shallow design also improved greatly the amount of radiant heat projected into the room. Rumford’s design is the foundation for modern fireplaces.

One famous tradition in the United States during the Great Depression was President Franklin Delano Roosevelt’s “fireside chats”, weekly radio addresses in which he made use of the family gathering time to state his views.

Many homes no longer have open fireplaces, their inefficient heating replaced by central heating, or electric heaters, its social function by the home entertainment center. Some fireplaces have been closed off not allowing them to be used. For homeowners that want the ambiance of a fireplace without the energy loss they have a few options. They can install into a new home or addition a high efficiency gas or wood fireplace. They do not have the appeal of a true open fireplace, but offer the fireplace effect while adding true heating value to the home. For people with existing fireplaces, the alternative to simply closing them up is to install a high efficiency gas, wood or biomass fireplace insert. Some governments have a partial ban on solid fuel burning fireplaces due to air pollution. Ventless fireplaces have received attention recently: they are free standing, requiring no chimney and no hearth. Prefabricated fireplaces are popular because of their lower construction cost and safer and more reliable operation. Brick or stone fireplaces can be designed to meet exact specifications for opening size, depth, and facing material. They cost more to build and require more maintenance.

Accessories

A wide range of accessories are used with fireplaces, which vary between countries and regions, and historical periods. For the interior, common in recent Western cultures are grates, fireguards, logboxes, andirons pellet baskets, and fire dogs, all of which cradle fuel and accelerate burning. Heavy metal firebacks are sometimes used to capture and reradiate heat, to protect the back of the fireplace, and as decoration. For fireplace tending, tools include pokers, bellows, tongs, shovels, brushes and toolstands.

Fireplace Inserts

March 11th, 2010

Fireplace inserts are heating units that can transform an inefficient fireplace into an efficient, heat producing zone heater. It is installed completely or partially within the firebox area of an existing fireplace, which may be factory-built or masonry.

Fireplace inserts are usually made from cast iron or steel. It includes self cleaning doors made of glass through which fire can be viewed. Some inserts have fans that radiate heat in the room and some even have thermostats or remote controls for automatic regulation of fire. Most fireplace inserts are equipped with blowers for circulation of heat. These units are vented with the help of a working chimney. Vent free inserts are also available.

Fireplace inserts can be those of natural gas, EPA certified wood, propane, pellet, and coal. The inserts come in a wide variety of designs and colors and vary in size too. The size mainly depends on the length, width, and height of the opening of the fireplaces.

Fireplace inserts can be single or double walled units. In single wall units, room air is absorbed under the firebox and heating is done between the masonry walls of the fireplace and the backside of the unit. But in double walled units, space is provided between the interior and exterior walls for circulation of air and heating. The second type is the commonly used type of fireplace inserts which are safer and more efficient, compared to single-walled units.

Fireplace inserts are convenient and easy to use. They increase the efficiency of fireplaces and provide heat even if there is no power. Consumption of fuel in a cost effective manner is another added advantage.

Certain conditions should be checked for installation. One should also know to operate these heating units. So before purchasing fireplace inserts, it is necessary to consult a specialty retailer, who can provide necessary information about how to operate the insert and also its installation and maintenance details.

What is a Masonry Or Brick Fireplace?

March 6th, 2010

Most traditional fireplaces can be identified as masonry fireplaces. The creation of masonry fireplaces throughout the world continues to be included in the construction of new homes. Masonry fireplaces are created with the use of natural materials such as brick, cement blocks, or natural stones which will include the use of some sort of binding agent that helps to hold the individual components of the fireplace together.

Depending on the design, the masonry material may include one or more types of materials. A masonry fireplace may be constructed mainly of bricks that have been cured and fired, but treated to a façade of stones that are fixed in place with the aid of cement or other binders. The stones may be an eclectic mixture of shapes and sizes or smooth and uniform.

The masonry fireplace is created mainly for the purpose of acting as a heat-generating source within the home. The chimney section of the fireplace will be fitted with a flue and other mechanisms that allow the homeowner to close the fireplace when the device is not in use.

Masonry fireplaces are usually wood-burning fireplaces, but one may choose to install a gas jet into traditional fireplaces and make use of gas heaters or logs.

Another option is the environment friendly Ethanol Fireplaces – BioGrate which is for use inside existing fireplaces and may be easily used as a replacement within a standard fireplace, there is no installation except for placing it inside the existing fireplace. The hearth is equipped with a tank for about of 1.5 litres of Biofires BioFuel and a damper to adjust the flame height. The hearth dimensions have been determined in such a way to make it possible to place it inside most of the traditional fireplaces.

They may also be placed inside fireplaces with cast iron inserts (fireplace inserts with closed burning chamber). Using the BioGrate still allows you to enjoy living fire in your original fireplace, but is free of ash and one does not need to clean the fireplace and chimney. Smoke moving back into the room is a disadvantage in most of the traditional fireplaces, causing unpleasant smell, and in extreme cases leading to intoxication.

It is a relatively easy task to add a fireplace home if it is not already built with a masonry fireplace. It is also possible to purchase modular masonry fireplace systems that can be easily installed in the home, or even added to an outdoor patio as a source of heat on a chilly evening. The modular fireplace units are usually less expensive than installing a permanent masonry fireplace and require little or no assembly.

Why Choose an Electric Fireplace insert

March 6th, 2010

This is the first post in series on the different types of Fireplace inserts available to the consumer. IN this first post I will start with the electric fireplace insert. This has to be one of the original forms of inserts.

Typically this is on the cheaper end of the price range. With the fuel being electrical it makes for a very easy and cheap installation. There is no need to worry about installation of propane tanks which you get with gas systems.

So what do you get with an electric fireplace insert, three main components, the heat, the back flames and the logs.

The heat, this is generated by a heating element within the fire. Typically you will buy based on the BTU level. For information on BTU selection check my post on the topic. The elements are standard and their isn’t much difference between the various units.

The back flame, heres where you start to pay for what you get. The back flame is the image the fire projects to suggest a real fire. This is normally cast onto the back of the fire in a flickering manner that gives the impression of a real fire

The logs similar to the back flame, the more you spend the more realistic they look. Electric fireplace insert logs tend to have the bulbs inside them and are designed in such away to let light emit. This is done in such away that they look alight.

I’m not a big fan of this type of fireplace as I prefer a live flame. However for multiple reasons you may pick an electric format. My favorite of the ranges is the Arrowflame series, the log design and back flame give a good impression.

I also like the Drayton electric fireplace, this has a more subtle lighting effect that works better.

If you have questions or comment on electric fireplace inserts please post them below.

Facts About Wood-Burning Fireplace Inserts and How to Make Them Work

November 27th, 2009

Many households enjoy the antique atmosphere of having a fireplace serving as the centerpiece of any living room. But it takes a little bit of knowledge to understand how these traditional fireplaces actually work. Fireplaces cannot do their functions without any air as the fire will cease to burn. A draft then occurs after the air is channeled towards the fire and subsequently heated thus pulling the air from inside up the chimney. A vacuum is then created pulling the cold air in which is the main problem here.

Wood burning fireplace inserts are there to solve the problems when it comes to handling the burdens and expenses involved. Because these wood burning fireplace inserts use the same working technologies that wood burning stoves use, it is sure that these types of fireplace inserts will increase the heating efficiency of the fire being burned while maintaining Environmental Protection Agency certification to ensure that they can be safely used within the home.

Wood burning fireplace inserts are primarily made up of cast iron or plate steel to ensure clean burning and they have frontal doors that are made of glass to allow a clear view of the fire. These doors are special because they are self-cleaning so they can stay closed to further increase the heating efficiency.

Many of these fireplace inserts have blowers that are built in to enhance heat circulation in the room that it is installed in as well as other adjacent rooms. Depending on the model chosen, these blowers can be found mounted on the sides of the insert or inside the front. Some models may allow manual control while others can be controlled automatically through the use of a thermostat.

Vermont Castings offers a small and fine selection of wood fireplace inserts to choose from that can match the decors of any home. It uses the heat circulating blower standard and is EPA approved to meet the safety and environmental requirements. When looking for good wood burning fireplace inserts that match the quality of the ones offered by Vermont Castings, make sure that they are highly efficient while at the same time requiring as little wood as possible to avoid extra handling. Also take note of the BTU, burn time, and heating area to make sure that you get the best benefits possible.

Installing wood burning fireplace inserts is possible only if the insert has a positive connection from the outlet to the very first section of the flue liner. This is needed to make sure that the smoke goes up the chimney while minimizing the combustible deposits that cause condensation within the fireplace. An ideal installation option is to fully reline the chimney and make use of the smaller pipe size to provide a better draft. This installation method adds a significant margin of safety. It also makes cleaning a bit easier of the stainless steel pipe goes all the way to the chimney’s peak.

With knowledge in choosing the right wood burning fireplace insert and setting up the wood fireplace insert, you should be able to feel the benefits of having one in your home especially during the winter time.
