Abstract
Abstract A superheater for a fireplace in order to obtain a greater amount of the heat from a fire and move the heat into the room; the device consisting of a cradle upon a middle of which logs can be placed for burning, the cradle consisting of a series of pipes through which air is forced so to become heated before blown into the room, the air intake side of the pipes being connected to a manifold into which a duct leads from the outside of the house so that fresh air, laden with oxygen, enters the room hot and maintains more oxygen for the fire so to burn more intensely.

Total Claims: 3
Claim 1
Independent Claim
206 words
An energy saving fireplace heater comprising in combination, a cradle placable into a fireplace and consisting of a series of generally C-shaped pipes in parallel spaced apart relation, each said pipe comprising a horizontal lower leg, a vertical leg and an upper horizontal leg with bends therebetween, an end of said lower leg being inserted into an air manifold connected to an air duct leading outwardly of a house, said duct being intercepted by a motor-driven fan having controls for variable speed, each said lower leg of each said pipe being supported above the fireplace floor by a leg near a rear end thereof, and the ends of said pipe upper legs extending into a room at various angular positions, said manifold being located outside the fireplace on the room floors wherein said ends of said pipe upper legs are all retained in a common supporting plate, wherein a valve is provided along each said pipe horizontal lower leg including an outlet directing air toward a fire upon said cradle, said valve comprising a sleeve slidingly mounted over a perforated portion of said lower leg and including a handle extending beyond the manifold into the room for controlling the amount of air directed upon the fire.
