2.4 Fuel and water quality requirements

2.4.1 Logs

The BSV 20/30 boiler is designed for the combustion of untreated wood. With the BSV 20/30 boiler, you use

wood in the form of logs (fuel in accordance with § 3 of the 1st BImSchV No. 4). The boiler is also ideally

suited for use in hot water heating systems.

The fuel should have the following properties:

- Dry, untreated logs with a maximum water content of 20%;

- The firewood is split and adapted to the size of the filling shaft;

- The logs should have a length of approx. 50 cm and an edge length of max. 10 cm.

Wood info

Units of measurement when buying logs

Various units of measurement are used when buying logs. The units used every day are

Solid cubic meter (Fm) (Ster)

A solid cubic meter is one cubic meter of wood without cavities. This corresponds to the size of a cube with

edge lengths of 1 m wide, 1 m long and 1 m high.

Cubic meter (Rm)

A cubic meter is one cubic meter of loosely stacked wood, including the cavities. In southern Germany, the

term “Ster” is also used for this.

Bulk cubic meter (Srm)

A bulk cubic meter is one cubic meter of loosely stacked wood with cavities.

Comparison of cubic meters - bulk cubic meters

Conversion factors can be used to compare the different units of measurement. The type of wood, i.e. soft-

wood or hardwood, and the length of the billets must be taken into account.

When using logs, it is essential to ensure that the moisture content is below the legal limit of 25%. 25% wa-

ter content corresponds to a water content of approx. 20%. Freshly harvested wood must always be dried for

one to two years before use - depending on the nature of the storage location and the state of preparation

(sawn or split).

There is a difference between the water content and the moisture content of the wood. The water content

is the mass of water in the wood in relation to the total mass of the wood. The moisture content of the wood

refers to the mass of water in relation to the dry mass of the wood.

If the fuel is too wet, unnecessary emissions are produced during combustion. In order to maintain an opti-

mum water content of 15 to 20 percent in the wood for combustion, the logs must be stored in a well-ventilat-

ed place protected from rain.

The individual logs should be stacked in such a way that air can flow through the wood pile and there is no

direct contact with the ground.

The storage period is one to two years, depending on the type of wood and the ventilation of the storage lo-

cation.

Storing firewood

Storing firewood correctly

1. store your firewood in sunny, well-ventilated areas (south and west sides of your building);

2. create a dry background (pallets or logs);

3. store your firewood at least 15 cm from the ground;

4. your firewood dries particularly quickly when stacked crosswise;

5. cover your firewood with a rain cover after the summer drying period;

6. if you store your firewood under a canopy, a house wall or an airy wooden hut, leave a gap of at least 10

cm between the wood and the building wall for ventilation;

7. if possible, store the day's fuel consumption in your heated room.

1 Canopy or roof overhang 3 Stacked without supports (at the edge)

2 Supports 4 Round timber cross bearing

Principle of drying:

The wood surface is heated (A) and the water evaporates (B). The air absorbs the water vapor from the

wood surface (C), the air cools down (D), falls downwards (E) and escapes (F).

2.4.2 Heating water

Heating water

In modern heating systems, the quality of the heating water has a significant influence on the functionality

and service life of the heating system due to the combination of different heat generators and components

such as high-efficiency pumps or modern sensor technology. For this reason, there are corresponding na-

tional specifications such as VDI 2035 in Germany, ÖNORM H 5195-1 in Austria and similar regulations.

BRUNNER therefore recommends filling and refilling the heating system with appropriately treated water.

Drinking water analyses for the respective supply area can be requested from the responsible water supply

companies.
