Pevex 40 Inset Ecodesign Convector Cassette Stove

The Pevex 40 Inset Ecodesign Convector Cassette Stove is a beautifully crafted inset stove designed and built to high standards right here in the UK. Its full glass door window and straightforward air controls make it as easy to live with as it is to look at, while its compact dimensions — fitting a standard 16" x 22" UK fireplace opening at just 13" deep — mean it slots neatly into existing chimneybreasts without extensive building work.

With a nominal output of 4.5kW and an impressive 80% efficiency on wood (83.5% on smokeless fuel), this stove delivers noticeably more warmth than a traditional open fire. The generously sized firebox accepts logs up to 290mm in length, reducing the need for constant reloading and making for a more relaxed fireside experience.

Installation flexibility is a genuine strong point. The stove can sit directly on a hearth or be elevated into a wall opening, and it can be finished with either a three-sided or four-sided frame to create a truly bespoke focal point in any room. Whether you're renovating a period property or updating a contemporary interior, the result is a striking centrepiece that earns its place.

Fully Ecodesign 2022 compliant and DEFRA approved as a smoke exempt appliance, the Pevex 40 Inset is suitable for use in smoke control areas across the UK, giving homeowners in towns and cities the freedom to enjoy a real wood-burning fire with complete confidence.
