Things are getting serious with the energy district of Feldafing.

The heating in the basement of the gymnasium will be replaced.

Two new combined heat and power plants will supply six buildings with heat from the fall – if they are delivered in September as planned.

Feldafing

- It's actually a normal heating exchange that takes place in the Feldafing gym.

And yet it is much more: It is the beginning of a new era of energy supply for Feldafing.

In addition to the gymnasium, the energy quarter will supply five other buildings: the assisted living, the kindergarten, the library, the old police station and the fire station.

This makes Feldafing significantly more energy self-sufficient and, above all, the investment is an important step towards CO2 neutrality.

Work has been going on on the new heating since last week.

The old one has already been removed, red-lacquered metal parts, sometimes more dented, sometimes less, lie in front of the boiler room next to the underground car park.

Behind it, the three employees from H+V Energietechnik from Nordkirchen near Münster have already installed the new buffer storage.

They will later store the excess heat and release it when needed.

There is a lot of air in the boiler room because the old system is out and the new combined heat and power plants are not there yet.

The heating distributor is already attached to the wall, with the appropriate labeling: "Floor heating, ground floor + upper floor" is written there, for example, or "Ventilation system, 2nd floor heat meter".

Nothing is connected yet, but it should be done by the end of the week, as H+V boss Wendelin Vogt says.

Since there is no heating at the moment, a replacement heater ensures, among other things, that the water in the assisted living facility is warm.

The mobile heat pump is as big as a trailer, it is located north of the gymnasium and draws heat from the air.

"It was last in the Ahr Valley and heated a hotel," reports Vogt.

The block-type thermal power station there, which his company had installed, was flooded during the flood disaster.

The company had applied for the contract with the municipal planning company in the course of the second call for tenders.

In the first round nobody had reported.

That's another reason why the project kept getting delayed, as Pewu employee Teresa Janik says.

"Because of the funding, it was very important to adhere to all the guidelines." The funding for the energy quarter is decent.

260,000 euros come from the federal government, the project should cost a total of 900,000 euros.

The first municipal council decision to found the energy district was made in July 2019, and Pewu and energy consultant Arthur Dornburg have been working on it ever since.

In September, so Vogt and the Pewu hope, the combined heat and power plants should be delivered.

Then Vogt and his employees come back from North Rhine-Westphalia to install the 1.45 meter high cubes with a size of one meter by 2.40 meters.

Vogt just got a taste of how it can go.

He needs ten sliders, but the relevant wholesaler only has eight.

"I was able to take two with me, I'll get six more," he says.

"It's crazy that you have to run after such small things."

Small things for the big picture.

The next steps for the energy district are the installation of photovoltaic systems to produce the electricity for the combined heat and power plants.

Until then, they will be heated with gas, as Pewu boss Andreas Keller says.

The gymnasium roof is probably structurally unsuitable, and in the case of the old police building, it is not yet clear whether the monument protection authorities will take part.

However, PV systems are planned for assisted living and the library.

And a PV field at the building yard - then the Feldafinger path to CO2 neutrality has become significantly shorter.
