    Hot water cylinder with TWS

    WT-T is a hot water cylinder with TWS technology inside (coil) that works quickly and efficiently. Thermia WT-T has an outlet for an immersion heater and HWC (hot water circulation) and can be used as a final heater in domestic systems to guarantee the right temperature of outgoing hot water. The WT-T cylinder fits perfectly to hot gas technology available with Mega and Solid Eco heat pumps.

  • More hot water, faster

    More hot water, faster

    WT-T is fitted with our TWS (Tap Water Stratification) technology. This means that hot water is produced faster and at higher temperatures than with traditional technology. Because the hot water is diluted to tap water temperature, the volume of usable hot water is considerably higher thanks to the high temperature.


  • Flexibility


    Thermia WT-T is available in 300 and 500 liter sizes and can be cascade-connected if greater volumes are required.

  • The essence of Scandinavian durability

    The essence of Scandinavian durability

    The WT-T hot water cylinder is made with pickled stainless steel, which makes it extra resistant to corrosion, as a result of which no sacrificial anode is needed in the tank.

Incredible, but true…

Incredible, but true…

The sun sends the earth 174,000 terawatts of free energy – every day.

It makes sense to use this gift of nature to heat and cool our homes.
