    Buffer tank for heat pumps

    Thermia WT-V is made up of a series of buffer tanks that can be used to increase volume, for flow equalization and the reduction of any fluctuations in heating systems.

  • Flexibility


    WT-V 100, 200, 300 and 750 have four connections while WT-V 500 and 1000 have six connections. WT-V 300, 500, 750 and 1000 can be connected to an immersion heater.

    WT-V 500 FC, WT-V 750 FC and WT-V 1000 FC all feature connections on the front for easier transportation and installation. The boiler can easily be made narrower and easier to handle by removing the insulation.

    3-bar and 6-bar variants make it possible to use the units in buildings where a higher working pressure is required. Moreover, both the 3-bar and 6-bar variants are available in a DN 80 version, with 4 DN 80 connections for applications where a larger flow is required.

  • The essence of Scandinavian durability

    The essence of Scandinavian durability

    The WT-V buffer tank is made from black carbon steel, which has two advantages: it is resistant to corrosion and other chemical deterioration and performs better than most other materials in environments that experience a high level of shock and vibration.

    Moreover, black carbon steel can be produced from recycled materials and is easy to recycle later, meaning fewer CO2 emissions. These characteristics make black steel a great choice for projects that prioritize minimizing environmental impact.

Quality is part of our DNA

We have always followed the same basic philosophy: to have the best products on the market. Or in the words of Thermia’s founder, Per Anderson himself: “The products one releases must be not only the best of their time, but before their time, over time.”

To this day, this philosophy forms the backbone of all products developed by Thermia.
