HEATWAVE

Is Austria set to break record for longest heatwave?

The whole of Austria remains under a heat warning until Friday, with temperatures in some parts of the country slated to hit 36C over the next few days.

Despite a long cold and rainy spell at the beginning of the month, August in Austria is ending in an outdoor sauna.

It’s been a month of extremes, with the first third of August marking Austria’s coolest since 2006 – followed by this summer’s longest heatwave – and possibly ever.

The University of Innsbruck – which has measured weather and temperatures in Austria since 1777 – previously recorded the Tyrol capital’s longest heatwave in 2003.

That heatwave, which meteorologists define as at least three days in a row of temperatures above 30C, lasted for 13 days.

The current heatwave is not expected to end until Saturday. If it lasts that long, it will set a new heatwave record of 14 days.

The Alpine city has also had nearly 30 days this summer above 30C. That’s above the average of 22 it saw between 1991 and 2020.

Meanwhile, the capital in Vienna saw another record. At 25.5C, the city saw the warmest night ever recorded in the final two weeks of August – giving little chance for residents to be able to cool off in the evening from scorching daytime highs.

To help deal with the heat, local authorities recommend comfortable and loose clothes, lukewarm drinks to keep the body hydrated, and to take midday breaks if possible.

Vienna reveals new plan for how to move away from gas heating

Authorities in Vienna want to replace the city's 600,000 gas heating systems with greener alternatives and have presented a plan for how they will do it.

Vienna reveals new plan for how to move away from gas heating

The “Vienna Heat Plan 2024” was presented this week which outlines a concrete strategy for replacing the city’s 600,000 currently installed gas heating systems with renewable energy alternatives.

Vienna has committed to ending its reliance on fossil fuels for heating and hot water by 2040.

As part of this goal, the capital wants to replace around 600,000 gas heating systems with renewable energy alternatives. On Monday May 8th the city presented the “Vienna Heat Plan 2024”, providing a clear plan for this transition.

The plan considers all buildings in the urban area and identifies where it is possible to expanding district heating, referring to a centralised heating system which efficiently serve multiple buildings.

The goal is to make district heating completely climate-neutral by 2040. Additionally, the plan also identifies areas where alternative solutions may be necessary, reported ORF.

The plan divides areas in three categories 

The areas in Vienna have been categorised into three groups based on demand and local conditions.

The first category include areas where district heating is most suitable.

The second category refers to areas with good potential for local heating networks. These networks can accommodate smaller, localised heating systems that serve buildings located close to each other. Additionally, the third category includes areas where individual climate-neutral heating solutions are needed for single buildings or properties, ensuring necessary adjustment to specific needs of a property.

Additional divisions within these groups have been made, considering factors like existing district heating connections and the possibility of expansion. The city wants to expand the district heating network to cover 1,700 kilometres in the future, according to Vienna.at.

Geothermal energy planned to be used in outer districts

The areas selected for local heating networks are mainly situated in the outer districts of the city. In those areas authorities plan to use geothermal energy, heat derived from the Earth’s core. Through the use of heat pumps, the plan is to supply heat to multiple buildings simultaneously, reported ORF.
