TermaTech TT20R

The TermaTech TT20R combines a gently rounded profile with straightforward operation and a practical 5kW nominal heat output. Its elliptical black-steel sides give it a softer appearance than a conventional square stove, making it well suited to customers looking for contemporary TermaTech design in a versatile size.

With an operating range of 3–7kW, the TT20R is designed for spaces requiring controlled, dependable heat without an unnecessarily large appliance. TermaTech quotes an indicative heating area of 30–120m², although the output required for an individual room will depend on insulation, layout and other building characteristics.

Convection helps circulate warmth around the room, while the airwash system helps keep the fire view clear during correct operation. Combustion is managed through a single air-control handle incorporating a startup and boost function, keeping everyday use uncomplicated.

The stove has a ventilated cold handle, an ash drawer and a deep combustion chamber incorporating a cast-iron base and cast-iron inner door frame. Its flue can be connected from the top or rear, with a UK 150mm flue spigot supplied with the stove. An optional Ø80mm TermaTech Airbox system is available for a dedicated fresh-air connection.

TT20R is listed for use in UK Smoke Control Areas when installed and operated in accordance with the approved exemption requirements. Use in a Smoke Control Area requires the separately purchased TermaTech DEFRA kit, part number 69TT2022DK, which is not included with the stove.

Up to 5-year warranty, subject to TermaTech’s warranty terms and conditions.
