An electrical heater and method includes heating member, a cable, and a connector. A resistance heating element is within a sheath of the heating member. A proximal end of the sheath is inserted into a slot of a first fitting and welded to the first fitting with first and second leads extending into the first fitting. The second fitting is threadably engaged with the first fitting. The second fitting defines a central bore disposed about the axis. An end of a power cable extends into the second central bore. A first wire is coupled to the first lead. A second wire is coupled to the second lead.

A heater for melting glass includes: a heating member containing carbon (C) configured to emit heat rays upon power feeding; and a tubular member made of metal configured to have one end closed, and to house the heating member. The heating member includes a first heat generating part and a second heat generating part along an extending axis direction of the heater, and the first heat generating part is arranged at a position closer to the one end of the tubular member than is the second heat generating part. Denoting a unit-length resistance of the first heat generating part along the extending axis direction by X (Ω/m), and denoting a unit-length resistance of the second heat generating part by Y (Ω/m),

( 1/30)X<Y<(½)X  Formula (1)

is satisfied.

An inline heater includes a heater core that includes a heat spreader assembly comprising a tubular heat spreader that extends axially along a longitudinal axis and that comprises an external surface. The heat spreader assembly includes a fluid inlet and a fluid outlet. At least one conduit extends helically about the longitudinal axis of the heat spreader between the fluid inlet and the fluid outlet to define a fluid heating flow path that fluidically connects the fluid inlet and the fluid outlet. The heat spreader assembly further comprising an electrically operated heating element for heating the heat spreader.

Disclosed is a heating element (1) for a non-combustible aerosol provision device (100), the heating element (1) having a rod (10), wherein the rod (10) has a longitudinal axis, a distal end portion (13), and first and second tapered portions (11, 12) at respective longitudinal positions along the longitudinal axis. The second tapered portion (12) extends from the distal end portion (13) towards the first tapered portion (11), and a cross-sectional area of the rod (10) increases with distance from the distal end portion (130) in each of the first and second tapered portions (11, 12). A first angle between the longitudinal axis and an outer tapered surface (11s) of the first tapered portion (11) is smaller than a second angle between the longitudinal axis and an outer tapered surface (12s) of the second tapered portion (12).
