The heat in Marktl am Inn is generated centrally in a modern heating plant, which forms the heart of the district heating network. There, various renewable energy sources are combined and stored efficiently.
Renewable heat generation
The heating supply is based entirely on renewable energy, using a large-scale heat pump and a wood chip boiler.
The large-scale heat pump has a capacity of 600 kW and is powered by electricity from 100% renewable energy sources. The electricity is sourced from the public grid via a dynamic electricity tariff, enabling the system to passively help relieve the strain on the electricity grid and generate cost-effective heat as base load.
The 330 kW wood chip boiler can handle peak heat demand and provide redundancy. The heating plant has already been designed with sufficient space to double biomass generation capacity, enabling the supply area to be consolidated and expanded in the long term.
Efficient heat storage
A key component is the heat storage tank, which enables the flexible use of renewable energy.
Heat is generated specifically at times when electricity from renewable sources is particularly cheap and readily available. The heating network is then supplied reliably from the buffer tank in line with demand.
