How heat accumulation stoves work
Unlike conventional stoves, heat accumulation models are built with high thermal mass materials such as cast iron or dense refractory ceramics, which retain thermal energy during combustion. Once the fire has gone out, the stove continues to emit stored heat over an extended period. This delayed heat release transforms the stove into an efficient, passive heating system and an attractive central feature in any living room.
Sustainable and cost-effective heating
These modern fireplaces offer a sustainable alternative to electric or gas heating. By maximising fuel efficiency and reducing heat loss, heat accumulation stoves help lower energy costs and minimise environmental impact. They are ideal for eco-conscious homeowners seeking both performance and design appeal.
Typical applications
-
Building high-mass stoves with long heat retention
-
Installing modern wood-burning fireplace systems
-
Enhancing energy efficiency in domestic heating
-
Reducing reliance on active heating during cold seasons
