Pellet fireplace insert SP20-IN

steelnatural convectioncontemporary

Overview
The sP20-in is a fully recessed pellet insert by Stûv that delivers a wide, calm and colourful flame thanks to Stûv's patented flower burner. The continuous-line combustion chamber extends into the door to provide an unobstructed view of the fire.

Fire appearance and combustion
The patented flower burner shapes a broad, calm flame with colour and dynamics similar to a wood fire, optimising visual comfort and even combustion.

View of the fire
The continuous-line combustion chamber extends into the door so the flame remains visible from any point in the room without interruption.

Operation and comfort
The sP20-in operates by natural convection: there is no blower and therefore no ventilation noise or audible pellet drop. Heat rises naturally, ensuring quiet operation. Front loading is performed through an integrated cold hatch. Ash removal is automated and the ash reservoir is generously sized to reduce maintenance frequency.

Installation and integration
The sP20-in is fully recessed: the flue is concealed, no visible grille, loading hatch and ash drawer remain invisible. Frame, niche and masonry finishes can be customised; uprights are available in standard or extended versions up to the ceiling. A pre-installation casing is fitted during structural works and the fire unit is installed at the finishing stage. The appliance is removable to simplify servicing.

Heating distribution
An optional ductable convection kit allows distribution of warm air beyond the main living space to adjacent rooms or upper floors.

Modernisation and compatibility
Designed to fit existing fireplace recesses to modernise a wood insert or traditional fireplace with minimal building work while preserving the original character.

Connectivity and control
Programmable heating periods and remote temperature adjustment are available via the Stûv Pellets app for scheduling and remote control.
