Stove Selection Check List
Pellet stoves feed their fuel into the combustion chamber automatically, burn it with almost no residual material, and only require low time commitments to refill fuel and dispose of ashes.
Wood-burning stoves offer a more romantic appearance and, with the exception of wood-burning stoves with water heat exchanger (water+), require no additional energy. Wood must be refilled once every hour to achieve the desired thermal output.
wodtke stoves get the most out of their fuel. The only requirement is that the fuel is thoroughly dried. This is not a problem with pellets or wood briquettes. Wood chips are fully dried as they are pressed in the factory. Sustainable natural wood straight from the forest must be dried first. This can take multiple years in the open air, or can be accomplished artificially in a kiln. You will need a protected and well-ventilated outdoor area to store your logs. If you don't have a suitable space in your yard or garden, you would be better served using compressed wood products or lignite briquettes. These can be stored indoors.
The nominal thermal output of your new stove must be appropriate for your living room. This is where the majority of your heat will be emitted; it is difficult to distribute heat through open doors and stairwells. For older buildings, you should assume about 1 kW of thermal output required per 10 m² of living room. In well insulated new buildings, passive, or low-energy houses, your heating needs will be much lower. You may be able to heat up to 20 m² with one kilowatt per hour.
Ask your architect or your home designer about your heating requirements.
A wood-burning or pellet stove doesn't always have to be operated at its nominal thermal output. The performance range for wood-burning stoves starts at about half of its nominal thermal output, ending about 20 percent above this range. Using just a small amount of wood, you can maintain a low level of thermal output. This is why our wood-burning stoves are designed for 25 cm logs. You regulate your heat output by changing the amount of wood in your stove.
With pellet stoves, you can easily change the thermal output by pressing a button, or control it automatically based on room temperature.
This stove is well sealed against the room of installation and disposes of a self-locking fire door. It has been granted a General Construction Authority Certification by the DIBt (German Institute for Building Technology). This stove is ideally suited for installation in highly insulated buildings such as low-energy or passive houses in combination with a controlled home ventilation system. For independent operation, the combustion air supply must use a duct leading outdoors or be connected to an exhaust air flue.
Of course, this stove can also be operated using room air for combustion, which does not require air supply from outdoors.
Please consult your local chimney sweeper in advance.
The thermal energy of wood-burning and pellet stoves with integrated water heat exchanger is fed through the buffer storage system into the heating cycle. Stored energy can be released from the buffer at any time and as needed. As most of the thermal output goes to the buffer storage, these stoves are ideally suited for use in low-energy or passive houses. Pellet stoves radiate only max. 20% of their nominal thermal output directly into the room, wood-burning stoves only max. 30%. So, the living room can't be overheated that quickly.
Please consult your local HVAC dealer to check the possibility of connecting your stove to the central heating system.
wodtke offers wood-burning stoves with integrated filters for especially efficient and low-emission combustion.
With innovative filter materials and a well-thought-out air supply, emissions and fuel consumption are effectively reduced, while the stove's efficiency and radiant heat exchange are increased significantly.
The depth filter made of ceramic foam and positioned above the combustion chamber retains the particles generated primarily during the initial phase of combustion. After the ignition temperature is exceeded, these are burnt, leaving the filter clear after each combustion phase. The filter also retains combustion gases for a longer period of time at a significantly higher temperature in the combustion chamber, leading to noticeably better combustion.
A massive storage block absorbs the heat generated in the combustion chamber to slowly give it off into the room. This way the wood-burning stove gives you hours of cosy fireside enjoyment and warmth.
Advance Planning Check List
Everything starts with a good chimney. You will need an appropriate flue or chimney as the foundation of your new stove. Check with your local chimney sweep early in the planning process for advice, and ask whether the flue or chimney in your home is suitable for the project, or if you need to build a new one and what it should be like. You will require an operating permit for your wood-burning or pellet stove before you can begin using it.
Consult your local chimney sweep association.
In general, the connection between your stove and flue should be designed to be as short as possible. Depending on the diameter of your flue, a minimum spacing of 35-40 cm is required between your stove pipe and combustible materials. Besides studded wooden walls, concrete ceilings and interior doors also require protection. You can find more specific information in our instructions. Connecting pieces to your wood-burning stove are fitted by Default for vertical pipe attachment. For horizontal attachment, the pieces can be re-fitted (not for rotating wood-burning stoves and pellet stoves).
Consult your local chimney sweeping association.
All flammable components, furniture or furnishing fabrics in the immediate vicinity must be protected against the effects of heat. In general, a distance of 20 to 30 cm on the rear or sides will be sufficient. At least a distance of 80 cm must be provided in the viewing area of the fire. You can find more specific information on individual stoves in our instructions.
Please observe the set-up instructions for the furnace you have selected.
Flooring made of combustible materials such as carpet, wood, or cork must be protected or replaced. We offer glass plates customised to work with our stoves. Fireproof floor plates must protect an area of at least 50 cm in front and 30 cm to the sides, measured from the opening of the combustion chamber.
Stoves require a sufficient air supply in order for combustion to function properly. In general, the air available in your living space will be sufficient. Modern buildings today, however, are being built more airtight. Additional installed ventilation systems in your kitchen or bathroom, additional heat sources such as a gas boiler, or ventilation systems can disable uninterrupted air supplies. We offer specific room-air-independent wood-burning and pellet stoves for these "problem areas". Alternatively, a room pressure monitoring system with the wodtke DS01 can fulfil the necessary safety requirements.
Please consult your local chimney sweeping association.
For safety reasons, the room in which your stove is set up must be a minimum size to ensure that natural air movement provides sufficient ventilation for combustion. At least 4 m³ of spatial volume is required per kW of heating output.
For example, to set up a 6 kW wood-burning stove, you would need at least 24 m³ of spatial volume. Assuming a ceiling height of 2.50 m, this would correspond to a room approx. 10 m² in size. The room may be smaller if air circulates between it and an adjacent room, or if an air duct to the outdoors is installed.
If you doubt your set-up location to be too small, please consult your local chimney sweeping association.
