Pellet Boiler Stoves (Idro)

A pellet boiler stove (idro) heats your living space with a visible flame and simultaneously feeds your central heating and domestic hot water. Part of the power radiates directly into the room, while a built-in heat exchanger directs the remaining power to the water, heating radiators or underfloor heating throughout the rest of the house.

What is a pellet boiler stove?

Also known as an idro-pellet stove, this device combines the ambiance of a wood stove with the convenience of automatic pellet heating for the entire house.
