TermaTech TT21 RS Grey Sandstone 5kW Woodburning Stove

TermaTech TT21RS Grey Wood-Burning Stove

The TermaTech TT21RS Grey is a contemporary wood-burning stove designed to combine efficient heating with understated Scandinavian styling. Featuring attractive grey sandstone panels and soft curved lines, it is an excellent choice for homeowners looking to add both warmth and a stylish focal point to their living space.

One of the standout features of this model is its heat-retaining sandstone exterior. The natural weight and thermal properties of the stone allow it to absorb heat during operation and continue releasing warmth gradually, helping to create a comfortable atmosphere even after the fire has reduced.

The TT21RS Grey is equipped with an elegant cast iron door that uses a magnetic closing system. By avoiding traditional moving door-latch components, the design provides simple operation with fewer wear parts.

The handle is cooled through convection, allowing it to be operated comfortably without the need for protective gloves during normal use.
