An electrical resistance water heating device, particularly intended for use in coffee or other beverage preparation machines, includes a solid metal heating plate having planar upper and lower surfaces. A fluid throughflow duct is formed between the upper and lower surfaces and includes at least two elongated, spaced, side-by-side branches having corresponding ends interconnected by a connecting conduit to form a continuous fluid flow path from a water inlet to a water outlet. An elongated slot is formed between each pair of side-by-side branches and at...
