Fireplace insert – with or without external supply of fresh air?

For fuel burning in the fireplace oxygen is needed, the fire consumed for heating air. What is removed, it must also be fed back somewhere. It also applies in this case. To ensure proper operation of the fireplace while protecting the residents, must provide adequate ventilation.

The issue of fresh air is always current with chimneys. In the past, the natural leaks around windows and doors for the air supply to the installation of a chimney space were sufficient so that no special measures were necessary.
That has changed. Density design with modern low-energy buildings can be no accidental openings in the building envelope. The manufacturer of fireplace inserts and stoves have responded to this new challenge. Modern wood heaters can be connected to an external air duct to secure the necessary combustion air.
This air duct is supplied at the top by an air-exhaust-chimney. Air exhaust chimney is a specialchimney, which is next to the Flue outlet also has its own Lüftungszug available at the Zuluftrohrleitung is connected from the stove or fireplace insert. Specialized companies guarantee you a professional chimney.

Nowadays you can find in almost every chimney manufacturers a solution for room sealed wood combustion. Partly it is well-crafted systems, for example, allow a preheat the combustion air. This is important for effective combustion in the fireplace insert. The preheated combustion air mixes better with the wood gases that escape from wood combustion in the combustion chamber, and allowing her perfect burnout before escaping into the chimney. The result is a high efficiency of the fireplace insert and low emissions.

Another possibility is to supply the combustion air with an air duct from the basement or outside. But that is sometimes associated with more complex structural measures, and of course with the breaking of the thermal envelope of the house. The air must be the room that serves the fireplace with combustion air can be fed back somewhere. Furthermore, protection against pests are provided.

In deciding whether the fireplace can be operated in the given case, with or without external air supply, only the instructions of the competent chimney sweep are essential. So the question you should immediately move into the planning phase of the fireplace with house building and construction, or consult the project with the chimney sweep in advance.This is responsible for final inspection of the fireplace and the hearth operators can save a lot of subsequent actions.

How to build a fireplace

A classic fireplace probably all know. For several centuries it was used as a heater. But today’s demands for efficiency and effectiveness of the heating system is no longer an open fireplace.

To meet the new needs of the operator, a fireplace (also developed gennant hot fireplace).Fireplace insert is equipped with a fireplace, the fireplace has closed, and thus for much better energy utilization of the fuel (usually wood) provides.

The fireplace insert has fireplace with glass door, so you can watch the fire as in a fireplace. Around the fireplace insert a chimney lining is created, so you can see after the installation of only the front of the fireplace insert.

Fireplaces (including fireplaces) are subject to acceptance. You should consult your plans in advance with your local chimney sweep.

This guide is only meant to make an idea about building a hot air stove. It is not a complete guide and take over for the accuracy of the information will not be liable. All requirements must be met in the construction of a fireplace.

The chimney lining can be executed from different materials, depending on what you want to achieve. Suitable for the storage of heat from a panel fireclay, bricks, lava rock, etc. If you do not need heat storage and a “cold” chimney lining is satisfied, then enables the whole chimney lining of lightweight calcium silicate boards (Silca, Promasil, …) make easily.

From aerated concrete (gas concrete) during construction of the panel recommended, as this time with the action of high temperatures and as a result aushällt developed dust in space.

Aerated concrete is only the chimneys of the brick lining the wall behind the fireplace and used on the inside he is also insulate with insulation panels (see above).

The entire floor, walls and ceiling inside the chimney must be insulated cladding. In addition to the appropriate carrying capacity of the soil must be checked.

The chimney lining should be provided with grate to secure the air circulation and prevent heat buildup. One usually placed under the grate and fireplace insert in the upper part of the fairing. In this way, the natural circulation of air is secured within the shell. Regarding the size and number of fireplace screens are to observe the instructions of the manufacturer.

For the fender minimum distances apply from the roof and combustible materials, which must be observed. The upper grate is placed directly under so-called “false ceiling”. This “false ceiling” is running diagonally up toward space and prevents the accumulation of hot air above the fireplace grid (which would otherwise at this point, a cushion of air created by hot air).

During construction of the chimney must also be ensured that adequate ventilation. The fireplace insert can be run either open flue or connect to an external air supply. These are commonly used air-exhaust chimneys, which have a separate channel for supply air and exhaust gases. More on this issue, see our article “fireplace insert – with or without external supply of fresh air”.

This video shows the construction of a chimney:

The fireplace insert is close to the chimney flues. This should have a minimum wall thickness of 2 mm. The connection to the chimney must be run tightly. For the sealing of all leaks, you can use the heat-resistant Ofenkitt. The chimney connector is designed with a double wall lining.

The chimney diameter should generally equal to or greater than the exhaust pipe diameter of the insert. Depending on the manufacturer you can possibly the exhaust pipe between the fireplace insert and chimney reduced to a smaller diameter. These adjustments affect the path of the flue gas chimney. A prior consultation with chimney is necessary here.

Some fireplace inserts have no exhaust valve. In sollchen cases, the installation of a flue pipe with damper is recommended. With the throttle valve can be regulated by the draft.

Hot air distribution
Fireplaces give some of the energy as heat radiation through the glass window and the fireplace insert from the body. These can be stored in the surrounding chimney lining. The greater part of the heat is given off as convection. Convection means that the chimney is heated by the air flowing through disguise.

This hot air can be used not only for the installation space but also result in more targeted areas. For this purpose, fireplace inserts are used with so-called hot-air jacket. Warm air jacket is an additional sheet metal casing that surrounds the fireplace insert and thus traps the warm air.

The hot air jacket has to be connected at the top of hot air outlets (hot air nozzle) to the flexible Aluflexrohren. This pipe can then be distributed to the desired way in the house.There are a variety of trim pieces, with which one can realize the branch.

Shorter distances (up to about 4 feet in a horizontal direction from the insert) can be realized by exploiting the natural air flow. If the branches of the distribution of warm air to be longer, you must use a thermo fan which carries the hot air.

Serve as the final elements of the air distribution grid or fireplace Lockable either anemostats (rotary disc valves).

As you heat the house with a fireplace

A fireplace or wood stove are becoming increasingly popular. Wood is a future-proof alternative to fuel oil or gas and the Holzverbrennnen is the proper handling and use of a modern heating system naturally friendly.

That’s why more and more homeowners access to a wood heater. Here are several options. From wood pellet boiler or furnace, stoves, up to a hot fireplace. Today we would like Focusing on the last alternative.

Fireplace as a whole house heating
A fireplace or hot fireplace is a modern heater, which can be used not only heat up the room but even the whole house. Fireplace is a further development of the fireplace. It consists of a fireplace insert and fireplace trim.

The fireplace insert is the basic element of the fireplace in his dar. combustion chamber the combustion takes place and the fire can be seen through the large glass door in the fireplace. For this reason, the hot fireplace is the perfect solution except when the heating function and the ambience of the living room to cheers from the flames.

For the heating of several rooms of the fireplace insert is additionally equipped with a hot air jacket. There is a sheet metal casing, which is mounted on the fireplace insert. The heated air from the fireplace insert is captured by the hot-air jacket and removed the hot air pipe. This pipe is connected to the hot air nozzle of the hot air jacket and comprises flexible Aluflexrohren.

The entire system is very flexible and, thanks to a variety of accessories, the warm air throughout the home. Special form available galvanized parts with which you can perform the desired turn-off are: Y-pieces, tees, reducers and connectors. The individual parts of the distribution of warm air are attached with clips. Leaks can be sealed with fireproof tape.

The heated air has a high temperature. Therefore, the distribution of warm air to make sure that the entire pipeline is adequately insulated. Here we use mineral wool. There are also special Aluflexrohre available, which already contain a layer of mineral wool insulation. The erleitert the workflow for the installation.

The distribution of warm air in the house can be done with the use of natural air flow (thermodynamics). This type of warm air distribution for shorter branches (up to 4 meters in a horizontal direction from the insert) suitable.

If the hot air can be transported over long distances, a heating fan is to be applied. There are special fans for fireplaces that are designed for high temperatures.

In the rooms to be heated is installed on the end of the hot air pipe grate or anemostats (rotary disc valves).

For the proper function of the distribution of warm air, the hot air taken away again forwarded to the fireplace insert. This one uses either natural leaks under the inner door or grille.

What to consider when a chimney?

Chimneys for fireplaces and stoves
A fireplace or stove requires a chimney principle, which discharges the flue gases. An exception is bioethanol fireplaces or Gelkamin that can be operated without a chimney.Chimneys for fireplaces and stoves must comply with EN 18160th

The chimney-minimum cross-section should at least open fireplaces 400 cm2 (20 x 20 cm) are in closed fireplaces 196 cm2 (14 x 14 cm).

A fireplace will usually have a separate chimney. The multiple occupancy of a chimney (multiple sites on a chimney fire) is only possible if the furnaces meet the DIN 18891 type first Sollche fireplaces / stoves should only be operated with a closed fire door. But even here there are certain rules and multiple use of the chimney must be approved in advance by the chimney sweep.

What are the chimney are there?
In the election of the chimney, you have several options available. Classic brick chimneys are being replaced by prefabricated chimneys, or chimneys.

Modern furnaces are due to its high efficiency, low exhaust temperature. This has the effect that the temperature of the flue gases at the chimney head falls below the dew point and condensation water is formed, which will damage the masonry. Modern chimney systems are often suitable for moisture-resistant and heating systems with lower exhaust temperature.

Effective stack height
In connection with the chimney is often referred to the effective stack height. As an effective stack height is defined as the portion between the exhaust pipe of the fireplace insert or the bottom ledge of the fireplace flue opening up to the top of the chimney opening.

The effective height of the Chimney must be occupied with a simple chimney at least 4 meters. Multiple finished chimneys are connected to the combustion of solid fuels require at least 5 m effective stack height.

The manufacturer of fireplace inserts or stoves may require greater effective stack height, to ensure the proper function of the heating system. The chimney (buoyancy of the flue gases) improves with increasing effective stack height.

Determine the required heat capacity at water fireplace inserts

The basis for effective and pleasant wood heating is the correct size of the insert, ie thedetermination of the required heat output. The heat demand of a building is dependent on several factors, such as the heat loss of each hall, as well as those planning the local climate.

Who plannt installing a hot water fireplace insert or stove, we recommend to best the exactheat requirements and the required heat output of the insert and the individual rooms are calculated by a professional. These data are necessary documentation from the house.

Who has this information may not be available, investigators with the help of our Simplifiedchart approximate the required heat output of the fireplace insert heat exchanger.

Cartridge Fireplace – a tailored solution for your fireplace

Who wants to convert a fireplace into an effective wood heating that is to weigh theretrofitting of the fireplace with a chimney tray.

Fireplace cassettes allow you to lock in a simple way to open fire. Thanks fireplace with heat resistant glass door, the flames can be observed as usual.

The fireplace tray is made ​​exactly to size and then inserted into the fireplace and sealed.This ensures that no smoke enters the room.

The retrofitting with a fire box has the effect that arises in the higher combustion chambertemperature. The cassette has drawn fire in the lower area to fresh air, this is then heatedand blown into the upper area again in the room.

The retrofitting fire cartridge has the following advantages:

Fireplace is being used effectively for heating
Reduces fuel consumption
Fumes in the room is prevented
Chimney improves
Danger of flying sparks is eliminated
the services we fireplace cassettes meet the demands of the ”fine regulation” (1BImSchV)
So if you want a fireplace, consider retrofitting with fire cartridge in any case.
