Abstract
A heating element made of metal mesh through which electric current may be passed to heat fluid passing through the mesh. The mesh is made of intersecting metal wires defining apertures though which the fluid to be heated passes. These apertures are made small enough to cause all the heating to be achieved by conduction and convection. Typical apertures sizes are 40 to 60 .mu.m effective diameter.
