Akvaterm

What Akvaterm does

Akvaterm is a Finnish manufacturer specializing in hot water accumulator tanks and HVAC tanks for residential and industrial heating systems. Founded in 1993 in Kokkola, Central Ostrobothnia, the company was originally established as Akvaterm Oy and in 2017 merged into Kaukora Oy, with production transferred to Kaukora's facilities in Raisio and Turku. The Akvaterm brand continues as a product line within Kaukora Oy's portfolio alongside the Jäspi and Jämä brands, with a dedicated sales office remaining at Kaarlelankatu 21 in Kokkola.

The company's product portfolio centers on customizable accumulator tanks ranging from 300 to 10,000 litres. The standard line includes Akva EK (versatile accumulator for all energy sources), Akva Geo (hybrid for heat pumps), Akva Solar (hybrid with solar coil), and Akva Nero (boiler optimization with proprietary LK Max finned copper coil offering double the heat-transfer surface area of typical domestic water coils). The Akva PRO line provides custom-engineered tanks for industrial applications including cooling water storage, equalizing tanks, and large-volume applications. All products use seamless 100mm polyurethane insulation with metal casing for thermal efficiency, and carry the Key Flag Symbol (Avainlippu) certifying Finnish origin.

Akvaterm operates a B2B hardware sales model through direct enterprise field sales with named account managers covering domestic Finland, Nordic exports, and Central European exports. The company also distributes through a network of heating installers and building contractors serving end consumers. Export markets account for approximately one third of turnover (as of 2018) and include Sweden, Norway, Russia, Germany, and the United Kingdom. Akvaterm is a wholly-owned subsidiary brand of privately held Kaukora Oy, which delivered over 50,000 heaters annually across its brand portfolio.
