Fireline inset and freestanding stoves are designed and engineered to be highly efficient and environmentally friendly. The wood burning and multi-fuel stoves provide heating using advanced firebox and combustion technology developed exclusively in our Telford laboratory. The results are our cleanest burning, most efficient stoves yet. Our wood burning stoves begin at 78% efficiency (where some other products peak) and rise to 81.5%. Our combustion technology is developed to harness the unique Fireline designed airwash as an integral part of the system and not just an add-on like some older designs of stove.
