Abstract
A shield for a combustion chamber of a hot water heater is described. The combustion chamber is a sealed or not combustion chamber and the metal heat shield encircles and is spaced about the burner and pilot which is located in the combustion chamber. The shield is also spaced from the skirt and a bottom wall of the combustion chamber. The shield is further provided with apertures to permit passage of air supplied by an air supply duct. The shield provides for heat concentration on a lower heat transfer wall of the inner casing containing the water to be heated. The shield also reduces heat loss through the skirt and the bottom end wall of the combustion housing.
