How to install a fireplace insert

Fireplace and stove: this is how you can install it at home

If you want a crackling fire in your house, you have the choice between a fireplace, tiled stove or fireplace. Before purchasing, you should find out more about a device.

In autumn and winter, many homeowners keep toying with the idea of ​​a fireplace in their own home. Experts explain what is necessary for installation.

The stove must match the chimney

The basic requirement for fireplaces and stoves is a chimney. If this is already installed in the house, it must be of sufficient size for the selected fireplace.

"If an old chimney does not fit the new fireplace, there is the possibility of adapting the chimney within a certain framework. For example, by pulling a steel pipe into an old brick chimney," explains Tim Froitzheim from the Central Association of Sanitary Heating and Air Conditioning (zvshk).

It is important that the stove fits the cross-section of the chimney and that the height is correct. "How high the chimney has to be is also determined by the respective environment," explains Alexis Gula from the Federal Association of the German Chimney Sweep Trade.

To protect the neighbors from smoke, the exhaust outlet must be at least 15 meters away from their windows or roof structure. "If that is not the case, the chimney must protrude at least one meter above the window or the roof structure," says Gula.

As Rolf Heinen from the Industrial Association of House, Heating and Kitchen Technology (HKI) in Frankfurt knows, the stove does not have to be placed directly on the chimney. However, "the closer the better" applies. Heinen explains that there is no point in laying the stove pipe generously through the living room. Long pipe networks also damage the chimney. "A short distance is not a problem," adds Gula. The stoves can therefore not only be set up directly on the wall, but also in the middle of the room.

Which oven variants are there?

According to the HKI, wood-burning stoves made of steel or cast iron are the most widely used heating devices. They have a window that allows a view of the flames. These ovens heat up quickly and heat the room with air currents. They are available in many designs - from rustic to timelessly elegant.

Tiled stoves are more individual. A stove builder builds them according to the customer's personal wishes. The combination of a large firebox with a relatively small viewing window is typical of these stoves. So little heat radiates directly into the room and heat accumulators absorb the heat, which means that the heat is released over a long period of time. In addition, tiled stoves score with a seat directly on or near the stove.

As a third variant, the fireplace has a heating insert made of cast iron or steel. It heats well, but should also convey the experience of fire. You can enjoy the view of the fire through at least one large window. It is therefore the efficient further development of the open fireplace.

Stoves and fireplaces need combustion air

"If they are properly installed and operated, they are safe systems," says Gula. Most rooms are large enough to provide enough combustion air. "The so-called dilution room becomes scarce if the air is still extracted by other devices such as extractor hoods, tumble dryers with exhaust air technology or controlled domestic ventilation."

Safety devices are stipulated here that step in in an emergency - such as contact switches for the windows or differential pressure monitors. This does not affect so-called air-independent fireplaces that have received certification from the German Institute for Building Technology (DIBt).
