They are based on exactly the same principle as pellet stoves but also have a water heat exchanger. They are therefore designed to be connected to a hydraulic circuit (central heating and / or domestic hot water DHW). They can heat the room, the water or both at the same time. They are a good solution for preparing DHW in winter.

They are, in fact, stoves hybridized between the boiler and the pellet stove, hence their second name: boiler stove.
