The Debrecen Sports Swimming Pool has been the emblematic center of the city and the region's aquatic sports life since 2006. The facility serves both international and domestic elite sports and competitions, water polo youth and public swimmers, while also hosting swimming training camps and various sports programs. The complex can accommodate more than 1,200 people, making it ideal for organizing prestigious sports events. The backbone of the Sports Swimming Pool is a 50-meter, 10-lane competition pool, one of the special features of which is the movable partition, thanks to which the pool can be used in a 25 or 33-meter configuration, making it suitable for short-course competitions, water polo matches and mixed programs. The competition pool is complemented by a 25-meter training pool, a teaching pool, as well as a jacuzzi, a plunge pool and a Finnish sauna. The swimming pool also has an outdoor thermal pool, which helps regeneration after training and competitions.
The Debrecen Sports Swimming Pool is heated partially by the Komondor supercomputer, installed in the local university. The heat produced by the supercomputer is transferred to the pool, and this ensures the heating of the pool area. This was an investment with a quick payback, and the pilot year was successfully concluded.
The waste heat continuously generated during the operation of the supercomputer located on the property next to the swimming pool is transferred to the swimming pool’s mechanical room via a heat exchanger and a pair of pipes, where it is utilized by the building’s heating system through the installation of a heat pump.
Technical innovation
292531.25 EUR (115 Million HUF (net))
The investment consisted of two financial sources: Debrecen Sport Centre own resources and financial support from Municipality of Debrecen.
Based on current parameters, the payback period is expected to be 8 years. (The payback period depends on the unit price of the district heating purchased; in other words, the figure is quite different when the price was 56 HUF/GJ at the time of the investment compared to the current price of 9,033 HUF/GJ.) Until waste heat is available, it is a long-term investment.

Yearly energy usage is electricity: 870 000 kWh and heat: 9000 GJ. This innovation is a win-win situation for both parties. Operating a supercomputer would involve costs associated with dissipating waste heat, while the swimming pool serves as a heat sink capable of absorbing and utilizing that heat for nearly the entire year. With a favourable exchange rate, operation is cost-effective.
There are several other developments have been planned that would reduce the building’s reliance on district heating for its heating needs, e.g. HPC Phase II (High Performance Computing) – if the HPC plant were to operate at higher capacity, A heating system that will use geothermal energy is also planned (a shallow geothermal energy usage - 100 – 200 m depth boreholes and heat pumps)
