Electrical thermal storage heater

摘要

A constant convection warm air flow is achieved from the storage heater by means of a multitude of small; diameter holes through the insulation material and one or more events in walls of the casing. The electrical heat storage appliance (1) has electric heating elements contains within thermal storage material (12). Holes of relatively small diameter (22) are provided in the insulation (14) to allow a constant flow of convected heat to be supplied through at least one side wall (21) through vents (28, 29).
