Bad Wiessee – Bad Wiessee wants sustainable heat supply for planned projects.

The Committee on Energy, Climate and Mobility has now made an initial decision.

It is a topic that is currently burning under the nails, as Mayor Robert Kühn emphasized at the most recent meeting of the Committee on Energy, Climate and Mobility: the use of renewable energies, including heating with wood.

"In view of the war in Ukraine, the topic has moved onto the agenda with a vehemence that was unimaginable recently," said the mayor.

Specifically, this evening was about the future heat generation for the planned new day care center and elementary school as well as for the sports facility and the two community centers on Hagngasse that are being planned.

Wood pellets or wood chips as fuel

Although the meeting had also been announced as a participation committee for citizens, interest seemed to be rather restrained.

Just two interested people had gathered in the meeting room for a specialist lecture and subsequent discussion.

At the beginning, expert Bernhard Haberl from the Lower Bavarian company HDG presented various options and boiler systems, in order to then specifically address the circumstances and needs in the municipality of Bad Wiessee.

For the needs of the four objects, a system with an output of 800 kilowatts is necessary, the expert explained.

Wood pellets or woodchips could be used as fuel, although Haberl recommended pellets because they take up less space for storage and are easy to handle.

Three locations are possible:

• the old fire station

• the boiler room of the elementary school

• a location on the Hagngasse site

Location elementary school has advantages

However, the installation of a large boiler would not be possible in the two existing buildings, explained Haberl.

The output would have to be achieved with two 400-kilowatt boilers each.

The elementary school location would have the advantage that after the old oil heating system had been removed, the existing system could be built on.

"With a wood heating system that includes the existing building, you are future-proof," the expert finally concluded.

Haberl's lecture was then followed by a lively discussion, which revolved around the question of fuel.

Rolf Neresheimer (FWG) expressed skepticism about the pellet variant in view of the price development.

“They are currently chasing the price of gas,” he pointed out.

From an ecological point of view, he also saw the long delivery routes as a minus, while wood chips were produced on site in large quantities.

Prefer regional availability

Bernd Kuntze-Fechner (SPD) agreed.

Because of the regional availability, one should keep this variant on the screen.

Karl Schönbauer (Greens) was also convinced that this would keep the added value in the valley.

The question of possible subsidies also came up.

Martin Brugger from the Technical Building Authority explained that there are basically funding opportunities for the municipal company.

However, the municipality itself has no right to support for the measures.

Deadline for funding until 2026

Mayor Kühn warned at this point not to plan with subsidies from the outset.

The subsidies for the heating of the day-care center building have been applied for, but the corresponding measures must be implemented by 2026 in order not to lose the funding.

The question of whether two different locations for two boilers would make sense, such as the elementary school and Hagngasse, which could possibly be connected, was also discussed.

Peter Kathan (CSU) thought that was not very economical.

In addition, the line would not only run through community land, thus requiring easements from property owners.

The decision is made by the municipal council

Wilhelm Dörder (FWG) advocated a central location halfway around the Zeiselbach Bridge.

From there, the connection can be made via public roads.

Johannes von Miller (Greens) suggested having a general view of the establishment of local heating networks for the future.

Finally, Mayor Robert Kühn asked the members of the committee to discuss the topic in the parliamentary groups.

A decision will then be made by the council.
