Most solid fuel stoves are approximately 40-50% more efficient than an open fire and allow the user to have control over the rate of burn and heat output to the room. Often a large percentage of the heat generated by central heating is lost from a room where an open fire is present (even when not in use). The installation of a stove will mean that the room is much warmer as the air flow is greatly reduced due to the installation of a register plate and the ability to close the air controls fitted on the appliance.
