Jetmaster Standard convector box
The Jetmaster Standard Convection boxes offer the attraction of an open log or coal fire together with the extra efficiency afforded by the double skinned convection chamber. This clever but simple idea converts your open fire from 10% to 45% efficiency. It also allows you to have more control over the burning rate by use of the built in flue damper. The damper also reduces heat loss up the chimney when the fire is not in use.
The Jetmaster standard convector box is available to suit either a 16″ or 18″ British standard fire opening. Requiring just the removal of the existing back brick.
