Abstract (en)

A heater in the form of a hot air gun 1 has a heat mass (8,9) capable of storing heat energy from heat sources (13) and capable of transfering that heat energy to a fluid e.g. air to be heated. The air enters the gun 1 through inlet 6 and passes via conduit 10, in which it is heated by contact with the heat mass (8, 9) to a plenum chamber (11). A venturi (14) pumps the air from the plenum chamber (11) to an outlet (5), via a conduit (12) where the air is again heated by contact with the heat mass (9). The heat mass (8, 9) transfers heat to the air rapidly so that during a pulse of air, much energy is transferred, but between air pulses the heat mass acts as a reservoir of heat.
