Swimming center Vesiveijari, Kokkola
At Vesiveijari Swimming Center in Kokkola, spa guests can enjoy a comprehensive spa experience thanks to the indoor and outdoor pools. The spa is open all year round and there are also pools in the outdoor areas, where you can experience the variation of the seasons alongside Finland’s changing climate.
The city-owned spa wanted to improve the property’s energy efficiency and ended up recycling the heat from the pool and shower water back to the property. The system was introduced in December 2017, when the Ecowec hybrid exchanger was installed to heat pool and shower water and preheat new hot water before the district heat exchanger. In connection, an external plate heat exchanger and hydrostatic wastewater control enhance heat transfer without a heat pump. The system operates almost maintenance-free and significantly reduces the need for district heating and peak power.
