Most warmly recommended: Modern solid fuel heaters

Modern fireplaces for solid-fuels meet the highest requirements. They are safe, well-shaped and easy to use. Sophisticated combustion engineering makes their operation especially efficient and low-emission.

Multi-fuel: Flexible and comfortable

Renowned manufacturers offer a wide range of high-quality heating appliances approved and tested for wood and lignite briquettes. This allows you to make optimal use of the advantages of each type of fuel and to combine them intelligently. Make sure a grate is installed in the bottom of the combustion chamber and there is an ash pan.

A principle distinction can be made between so-called single-room fireplaces such as wood stoves and heating fireplaces and solid-fuel boilers with a heating circuit ("central heating system"). Combination with a solar heating system, linked via a buffer storage, is also possible. Experts call this a "hybrid heating system".


Individual solutions

Whether as a standalone or auxiliary heater, a single-room fireplace or a heating boiler or combined to form a modern hybrid system:

A solid-fuel burning device for lignite briquettes can be used flexibly in many ways — to suit your requirements and needs. Ask your specialised dealer about components and system solutions!

Single-room fireplaces

Multi Fuel Stove

The solid fuel stove — also called Scandinavian stove or multi fuel stove — is an ideal source of heat for all those wishing to have the experience of a "fire" in their homes, quickly and cheaply and without major construction work. The freestanding stove is a series-produced fireplace with a metal basic structure. Clad with metal, ceramics or soapstone, a wide variety of shapes and colours are available.

The combustion chamber is usually lined with a mineral material and should have a grate or a combustion chamber trough with a shaking grate. Moreover, to use lignite briquettes, it is advisable to use an appliance with a larger ash pan.

Solid fuel stoves give off heat to the room comparably quickly in the form of radiant and convective heat. Combustion air may be supplied through the installation room or from outside of the building.

Pot-bellied stoves / coal-burning stoves

The pot-bellied or coal-burning stove is the younger brother of the wood stove. With a much reduced design, practical utility is the main feature. Wrongly also called an "omnivore", some appliances can burn hard coal products in addition to wood and lignite briquettes. Carefully check the manufacturer's specifications in this regard!

The pot-bellied stove (also called "space heater") is made of steel or cast iron and usually has no mineral storage surfaces outside. The compact combustion chamber is designed as a flat or filling-trough firing without a viewing glass or with a smaller viewing glass than that of a usual wood stove.

Titles Stoves / Inset Stoves

Whether minimalist modern or traditional rustic style: the tiled stove is the epitome of wellness and cosiness. A hot-air tiled stove — also called storage heater — consists of a factory-made metal combustion chamber or heating insert with a downstream heat exchanger. It is contained in an individually encased, hand-crafted heating chamber made of mineral materials (e.g. tiles, fireclay etc.).

The combustion chamber usually is clad with a mineral material and, depending on appliance type, has a flat or filling-trough firing. Important: To be able to optimally combine wood and lignite briquettes, you should go for a heating insert with a grate and ash pan already at the planning stage. Ask your stove manufacturer about appliances approved for lignite briquettes.

Depending design and materials used, a tiled stove stores heat substantially longer than a wood stove. Also, depending on installation, several rooms may be heated simultaneously.

Heating fireplaces

The heating fireplace is the reasonable alternative to the "open fireplace" and characterised by substantially better use of energy and lower pollutant emissions. The heating fireplace consists of a factory-made metal combustion chamber (fireplace insert) with a large window. Be sure it has a grate and ash pan for "mixed fuels", so you can combine wood and briquettes.

The heating fireplace has a hand-crafted casing or is installed as a factory-made construction kit. Firing and heat emission are comparable to that of wood stoves, provided a heat exchanger is installed downstream of the combustion chamber.

Ranges / Cookers

The last years have seen a revival of the modern solid-fuel ranges, also called "coal-burning" or "wood-burning" ranges. They are primarily used for cooking and baking and at the same time give off heat to the room where they stand. The ranges often have a height-adjustable grate. Its position determines the amount of fuel and the burning time.

Ranges approved for wood and lignite briquettes give you the highest degree of comfort and flexibility. Ask your specialised dealer for information.

Pellet stoves

Due to their surface, special size and consistency, pellets cannot be burnt in normal stoves for wood and lignite briquettes. The small pellets require pellet appliances especially designed for this kind of fuel.

From a fuel reservoir, the pellets are mechanically transported to a combustion device where they are ignited. The correct amount of fuel is supplied automatically based on the defined desired thermal output. Pellets burn with a clearly smaller flame than firewood or briquettes. The burning rate is controlled via a fan system. The noise caused by the fan varies widely depending on manufacturer and design. Unlike most wood stoves, operation of a pellet stove as a rule requires electric power.

Before you decide to buy a pellet appliance, you should carefully check the wood pellet supply situation in your area.

Solid-fuel boilers and heating systems

Solid-fuel boilers / coal-fired boilers

If the primary aim is to permanently and economically generate heat, e.g. for a single-family house, modern solid-fuel boilers and boiler systems are a reasonable alternative. They enable the use of natural energy sources such as lignite and wood on a large scale and can be integrated into closed heating circuits. This is usually done by means of a buffer storage. Depending on the model, use as a gravity heating system may also be possible.
Modern solid-fuel boilers, coal-fired boilers or briquette gasifiers are characterised by especially efficient and low-pollutant combustion. Due to the high efficiency of a modern heating boiler, substantially less fuel is needed to generate the same amount of heat compared to older boilers.

As with an oil-fired central heating system, the temperature in various rooms can individually and comfortably be regulated by means of the control system of the water-filled radiators or the floor heating system. It is also possible to integrate a solid-fuel boiler into an existing heating system, e.g. with a condensing oil boiler heating and solar thermal energy system, to create an innovative hybrid system. In this way, a modern briquette boiler not only provides low-cost heat but also a maximum of comfort, flexibility and independence.

Water-containing stoves

They are the link between the conventional single-room fireplace and the real heating boiler system. Water-containing stoves and fireplace inserts feed part of the heating energy into the water circuit via water pockets and heat exchangers. In this way, the heat generated can be distributed across several rooms. In this respect, it makes sense to use a buffer storage. Usually, the central heating system (e.g. oil/gas heating, heat pump etc.) also supplies the heated water into the buffer storage.

The look of water-containing fireplaces often resembles that of the basic types such as wood stove, heating fireplace, tiled stove or solid-fuel range. However, their installation and planning is considerably more complex and should, therefore, at any rate be carried out by an experienced specialised dealer. To use lignite briquettes, you should choose appropriately approved appliances with grate and ash pan.
