Termatech TT21 Classic Wood Burning Stove

The TermaTech TT21 Classic Wood Burning Stove combines timeless Scandinavian styling with robust construction and efficient woodburning performance. Its distinctive rounded, almond-shaped design and traditional cast iron door create an attractive focal point in both modern and traditional homes. The smooth black steel sides and large curved glass viewing window provide an excellent view of the flames, while the compact design allows the stove to sit neatly against a straight wall or in a corner.

With a nominal heat output of 5kW and an efficiency rating of 81%, the TermaTech TT21 Classic is designed to provide comfortable warmth while making effective use of seasoned firewood. Its operating range of 3kW to 7kW offers flexibility for different heating requirements, and its convection design helps distribute heat throughout the room. A simple air control with an integrated ignition function makes lighting and managing the fire straightforward.

Practical features include a heat-resistant magnetic door closure, which avoids the need for conventional moving door-latch components, and an integrated airwash system to help keep the glass clear. The generous 4.5-litre ash drawer comes with a lid to help contain dust when emptying. An optional external air supply connection and top or rear flue outlet provide additional flexibility when planning your installation.

Designed with everyday usability and durability in mind, the TermaTech TT21 Classic is an excellent choice for homeowners seeking a quality Scandinavian woodburning stove with straightforward controls, attractive cast iron detailing and dependable 5kW heating performance.
