Room and Water Output Explained
The Achill 17.5kW splits its heat output between the room and your central heating system. At nominal burn, 6.1kW heats the room directly and 4.1kW goes to the water circuit. At maximum output, up to 11.5kW is delivered to the water, making it capable of contributing significantly to your home's radiator and hot water system. This makes it an excellent choice for homes looking to reduce their reliance on oil or gas central heating.
Clean Burn System
A tertiary air system pushes hot air into the firebox above the normal flame height, allowing excess gases to combust fully. This results in a cleaner, more efficient burn with lower particulate emissions.
Airwash
A specially placed vent draws air across the inside of the glass, helping to keep it clear and giving you an unobstructed view of the flame throughout the burn.
Warranty
Includes 1 year standard manufacturer's warranty. Register your stove online within 3 months of purchase to receive an additional 2 years, giving 3 years total cover.
