Why this product?
Airtight unit RT2012 / RE2020 compatible

Ideal for low-energy consumption construction (BBC), RT2012 or RE2020. The unit is equipped with a central fresh air input on a connection nozzle:
* no air intake in the room,
* direct connection possible to crawl space or external air intake.

Cast iron door and top

The thermal properties of cast iron improve the quality of combustion and the performance of the appliance. Cast iron parts are durable over time.

Cast iron-clad combustion chamber

In addition to its thermal properties, the cast-iron housing gives this model a unique style.

Clean glass

The clean glass system slows deposit buildup on the glass. An air supply above the glass creates a protective curtain. The preheated air is propelled along the glass. It triggers combustion of gas and volatile materials, thereby protecting the glass against smoke and soot deposits.


The unit operates with regular loading of small quantities of wood. This operating method is particularly high-performing and respectful of the environment.

Optional heat accumulator

Composed of refractory bricks, the Neosen heat storage kit continues to heat your interior long after the flames have disappeared. H 234 x W 500 x D 500 mm – Option reference P696300

Post-combustion system

Injection of pre-heated air into the combustion chamber The supplementary air intake in the back enables hydrocarbons to be destroyed at a high temperature. Complete combustion reduces pollution.

Removable handle

The handle is removable and placed high for the safety of children.
